Description

  The present invention is a scalp treatment (hair care treatment) solution for washing off the dirt on the hair and scalp, replenishing moisturizing components and the like to provide protection or shaping (styling) properties of the scalp and hair, and The present invention relates to a method for treating a hair portion to be used. In particular, the present invention relates to a treatment liquid and a treatment method for performing a hair care treatment suitable for a person having sensitive or inflammatory skin such as atopic property, or a hair care treatment suitable for a nursing care scene.

  In general, a shampoo process and a subsequent treatment process have been required to remove stains on the hair and scalp, replenish moisturizing components, and protect the scalp and hair. The shampoo liquid is blended with various cleaning ingredients and active ingredients such as moisturizing ingredients, and by devising these combinations, it has the safety as much as possible and the effectiveness from various viewpoints. Yes. The shampoo solution contains an active ingredient to improve hair feeling, styling, hair quality, etc., such as cationic polymers such as cationized cellulose and oils such as silicone. We are trying to improve the scalp and hair.

  In other words, although it is a shampoo, it is necessary to arrange not only the components to be washed but also the components that adhere to the hair, and the shampoo substrate is improved in fingering and foaming at the time of washing, and water rinsing properties after washing In addition, ingredients are blended and designed to produce a texture of squeak and hair (for example, Patent Documents 1 to 3).

  Conventional shampoos are basically characterized by washing with foam of a surfactant, and the foaming becomes worse as much as the scalp and hair are dirty. In order to avoid excessive baffling during shampooing, use a lot of shampoo solution at once, or re-wash with shampoo solution 2 to 3 times, and divide it into 2 to 3 times. It is necessary to remove the dirt step by step. Moreover, a lot of rinse water is needed for the washing off.

  Conventional shampoo liquids are designed to a level that can withstand the use of safety, but in order to exhibit the original safety, the washing-out process becomes quite important. The amount of water or lukewarm water used for shampooing is considerable, and for women's long hair, the amount of water required for shampooing reaches 5 to 10 cups in a regular basin. In addition, it can be washed away, but if left on or left unwashed, it may cause skin irritation or skin trouble. In particular, it tends to remain in the hair and scalp because of the treatment ingredients.

  In the case of a conventional shampoo solution, although it takes a lot of work, it is not always enough to remove dirt plugged in pores and dirt around the hair root such as old sebum and exfoliated keratin. It was not easy. The amount of shampoo used, and whether to use many shampoos at one time or to wash twice, are individually selected and adjusted by individuals. It was generally difficult to remove the nearby dirt.

  The conventional shampoo solution is not particularly suitable when there is a scalp trouble such as atopic dermatitis or other inflammation or hypersensitivity. Even after rinsing with a shampoo solution, the condition of the scalp quickly deteriorated, and itching, inflammation, dirt near pores, keratophylls, exfoliated keratin, dandruff, Or hair loss increases. Therefore, even if the hair is regularly washed, symptoms such as dandruff, inflammatory scalp, seborrheic dermatitis, dandruff, alopecia, and atopic dermatitis are not improved. Rather, it seems that only a moment washed with shampoo has been cleaned, and the condition of the scalp deteriorates after several hours.

  This is not only because keratin plugs and old sebum and exfoliated keratin are not completely removed from the pores, but also because it is irritating when washed with surfactant foam, and it can be irritating as much as possible. It is thought that this is because the shampoo solution cannot be completely washed away. Stimulation with shampoo solution during washing and stimulation with residual shampoo solution after rinsing cause rash and itching after washing the hair.

  That is, in the case of having seborrheic dermatitis or atopic inflammation, the condition of the scalp and pores seems to be reduced on the day of washing, but it is observed on the first and second days without washing with shampoo. Then, the inflammation itself tends to get worse. Therefore, it is necessary to wash the hair at intervals of about two days, but before the inflammation and dandruff increase, it becomes a rhythm that is reduced by treatment with oil. However, since the deterioration is returned to a certain level before the deterioration progresses too much, the level does not improve beyond a certain level.

  Development of hypoallergenic shampoos that can be used by persons with atopic dermatitis has also been attempted (for example, Patent Document 2). However, it is formulated with the idea of suppressing inflammation with herbal medicines while reducing the concentration of surfactant, and even though the safety is basically good, the cleaning action on pores and scalp is not The current situation is incomplete. For this reason, using a mild shampoo solution does not tend to improve inflammation with the passage of time.

  In conventional hair care methods, after washing with a shampoo solution and rinsing off, it is common to add oil and treatment components to the hair by applying a separate rinse solution or treatment solution (for example, Patent Document 4). In this way, not only does it require additional steps, but if the hair follicles have not been completely cleaned and an unnecessary ingredient such as a rinse or treatment agent is added to the scalp, the healthy state of the skin can be improved. Causes skin problems if damaged or accumulated over time. The same applies to the rinse component and the treatment component blended in the shampoo solution.

  In particular, if you use excessive shampoo twice a day, such as a morning shampoo, or a shampoo that does not have a sufficient cleaning effect, such as a rinse-in shampoo, there will be a fundamental shortage of shampoo safety problems and pore and scalp cleaning For this reason, even women who are not sensitive skin, etc., have caused scalp troubles such as hair loss.

  This is different from the original hair care system. Originally, the pores and scalp should be kept clean by arranging a mechanism to release the sebum of the scalp itself, and if so, it promotes healthy growth of the hair root itself by prompting sebum and eliminating skin damage. Should not interfere.

  On the other hand, as a hair care method, a method of cleansing pores and scalp with oil itself before shampooing, and then washing the oil with shampoo is also conceivable. However, if you actually try it, you can see that the oil does not drop well even if you wash it two or three times with shampoo. Even after washing three times, the oil does not fall sufficiently, so the styling of the hair itself is limited and the oil is wet.

In addition, it is also considered that aerosolized synthetic oil is used for wiping and cleaning for a completely different use from that for hair care (Patent Document 5).
Japanese Patent Laid-Open No. 10-175826 JP 2000-96083 A JP 2003-160797 A JP 2003-26549 A Japanese Patent Laid-Open No. 5-70340

  On the other hand, as a hair care method, it is also proposed to cleanse the scalp with a cleansing cream and wash it off with shampoo. However, cleansing cream itself contains various unnecessary things such as waxes, polymers, surfactants and parabens, so safety when applied to the skin is not perfect. In addition, the cleansing cream alone does not sufficiently clean the horn plug and requires a water-soluble shampoo, so the above-mentioned problems of the water-soluble shampoo remain. Therefore, in the care scene, the rinsing process for shampooing cannot be simplified, and a lot of rinsing water is required, so that the burden for hair care cannot be reduced.

  It is conceivable to use a massage or cleansing process such as oil, but always use an aqueous shampoo later. This is not a problem for healthy people, but it is a problem for those with a scalp trouble, such as those with weak scalp and sensitive skin. Although blood circulation promotion effect, relaxation effect, and removal effect of dandruff etc. are exhibited by massage, problems occur at the time of washing and rinsing with shampoo. Remove the oil, or make sure to apply a shampoo process somewhere, apply a large amount of shampoo agent, use foaming, and rinse with a large amount of water. In normal shampooing shampoos, the oil after oil massage in this case cannot be easily washed away. It can only be accomplished with a fairly clean water-based shampoo, the scalp problem seems to be considered, and the problem arises in the washout.

  Therefore, in the case of scalp with sensitive skin such as atopic dermatitis, it does not tend to improve, and does not promote sufficient self-sebum secretion, so a clue for solving cannot be found. Even when there is no scalp trouble, it is necessary to use a hair treatment agent after shampooing, or use a water-based shampoo blended with a treatment. Therefore, even if it appears that the pores are completely and safely removed after washing the hair, it does not stimulate the secretion of sebum and irritation is inevitable, so daily shampooing and rinsing It is necessary to wash and maintain the shape of the hair. On the other hand, inflammation and dandruff tend to get worse.

  The present invention has been made in view of the above-mentioned problems of the prior art, and in the treatment liquid and treatment method for washing off the dirt on the hair and scalp, and for protecting the scalp and hair or imparting formability, An object of the present invention is to provide a device capable of preventing or improving the occurrence of inflammation or reducing the burden for hair care.

  The hair part washing treatment liquid of the present invention is a hair component washing treatment liquid for washing off the dirt on the hair and scalp, and for protecting the scalp and hair or imparting formability. This is characterized in that a lipophilic nonionic surfactant having HLB 6 to 8 is dissolved or dispersed therein.

  Here, the vegetable oil of the low-temperature compression manufacturing method means oil extracted from a plant seed, fruit, nucleus, germ, etc. without undergoing chemical purification treatment or modification. In addition, the vegetable oil as a main liquid component means that the vegetable oil has a continuous phase even if the weight fraction of the vegetable oil is 50% or more and an aqueous dispersion phase or the like is included.

  The vegetable oil used in the present invention is preferably at least one selected from the group consisting of olive oil, pomegranate oil, hemp seed oil, jojoba oil, sesame oil, rice germ oil, grape seed oil and rosehip oil. More preferably, it is at least one selected from the group consisting of olive oil, hemp seed oil, sesame oil, rice germ oil, and rosehip oil. If these vegetable oils are used, they are effective not only for removing dirt on the scalp and pores, but also for preventing hair loss, alopecia areata, prevention of inflammation and hair loss, etc. depending on the vitamins and minerals contained. is there.

  Nonionic surfactants blended with vegetable oils have an HLB (hydrophile-lipophile balance) of 6 to 8 and are slightly lipophilic and almost equal to normal fats and oils. It has the safety of. Preference is given to triesters of higher fatty acids of oxyethylenated glycerin, such as POE (polyoxyethylene) glyceryl triisostearate. The compounding quantity of nonionic surfactant is 2-30 weight part with respect to 100 weight part of vegetable oils, for example, Preferably it is 3-20 weight part, More preferably, it is 5-20 weight part.

  Preferably, the essential oil is further blended with the vegetable oil. The essential oil is a volatile liquid having a fragrance obtained from plant leaves and leaves, rhizomes, bark, fruits, flowers, buds, resins, etc., preferably rosemary oil, lavender oil, sage oil, clary sage oil, tea tree oil And at least one selected from the group consisting of eucalyptus oil, ravensara oil and peppermint oil. The blending amount of the essential oil is 0.005 to 10 parts by weight, preferably 0.1 to 3 parts by weight, and more preferably 0.5 to 1 part by weight with respect to 100 parts by weight of the vegetable oil. The blending of essential oils is more effective because it can provide antibacterial, anti-inflammatory, antioxidative effects, and relaxing effects due to aroma.

  In addition, the hair part treatment method of the present invention, after applying the hair part washing treatment liquid to the hair part, washing the hair with a scalp and massaging the scalp, simply rinsing with water or wiping with a steaming towel, It is characterized by completing the washing, rinsing and rinsing of the hair.

  When the hair care treatment liquid of the present invention is used, no adverse effects are observed on the scalp and hair, the hair portion can be washed by a simple method, and no separate hair treatment treatment is required. In particular, it has an effect of preventing or improving atopic dermatitis and other sensitive skin and scalp troubles such as inflammation, alopecia or seborrhea.

  In addition, when shampooing as a care service, rinsing can be performed by simply rinsing a small amount of water or wiping with a steaming towel or the like.

  As described above, the hair part washing treatment liquid of the present invention is not an aqueous system but an oil containing an extremely safe surfactant component, and is completely different from a conventional shampoo liquid or a diluted liquid thereof with water. It should be called "oil shampoo".

  The hair part washing treatment liquid of the present invention has another feature in that it uses an unpurified vegetable oil obtained by a low-temperature pressing method, instead of a generally used refined vegetable oil.

  Vegetable oils used in toiletry products are almost always refined using organic solvents to improve odor and color, and use, for example, distribution with aqueous solutions. After removing the impurity components, the organic solvent is removed by heating and drying. In such a purification process, denaturation due to heat or the like is often caused.

  Conventionally, refinement of vegetable oil is generally regarded as quality improvement, and the merit of using a crude extract or a non-refined product has not been recognized at all. In the case of skin patch tests established as a method for evaluating skin irritation, there is absolutely no difference between low-temperature pressed oil of vegetable oil, solvent extracted oil, and chemically purified vegetable oil. Not observed.

  However, the present inventors recognize the difference between low-temperature compressed oil and refined oil that has been overlooked so far by adopting a completely new evaluation method called “wave search test” or “wave measurement method”. I was able to. In particular, when the test was performed by a person with a scalp that is vulnerable to irritation such as atopicity, the effect of improving skin inflammation was observed by using a cold-pressed refined oil. Such an effect was not observed at all when the refined oil was used in the same manner.

  “Wave search test” or “wave measurement method” is a method for quantifying whether the human body is beneficial to the human body in terms of what is called a “code” using the human body as an amplifier. It can be used as non-destructive data. In this case, regarding skin irritation, the difference in safety and effectiveness at a level that does not appear in the patch test appeared as a dramatic difference in actual specific situations.

  It is unclear what kind of component the difference between the low-temperature compressed oil and the refined oil was expressed specifically, but it is considered that the component removed as an impurity was very useful. This can be compared to the difference between brown rice and white rice. Rice is generally eaten as a symbol of abundance, as if it were a symbol of post-war Japan, “clean and delicious”. However, in fact, by using 3 parts of brown rice, polished rice, white rice, or non-washed rice, the useful ingredients are lost, and brown rice tends to be deficient in producing bodily toxins and maintaining alkalinity. It is recognized that it has the function of supplementing vitamins.

  In other words, in making the present invention, a style completely different from common sense, such as using brown rice in which white rice is considered to be natural, has been adopted, and the novel effect thereby has been applied to normal skin. It was confirmed by a method completely different from the stimulation test method and by an actual use test.

  In addition, as vegetable oil by a low temperature pressing manufacturing method, even if it was not necessarily obtained by the low temperature pressing manufacturing method itself, it can be used if it was extracted in the equivalent state. Moreover, the vegetable oil obtained by organic cultivation (organic) cultivation is preferable. In other words, if no chemical pesticides or chemical fertilizers are used, or if vegetable oils obtained from plants grown using only a small amount are used, irritation to the skin and other adverse effects caused by residual substances etc. should be excluded. Is more preferable.

  In making the present invention, a specific nonionic (non-ionic) surfactant is further added to the vegetable oil produced by the above-described low-pressure squeezing method. It has been found that it has the same level of safety and the effect of improving skin inflammation.

  Here, as described above, the specific nonionic surfactant is a slightly lipophilic one of HLB 6 to 8, and a polyglycerin surfactant, a polyoxyethylene sorbite fatty acid ester surfactant, etc. can be used. It is. However, as mentioned above, preferred are triesters of higher fatty acids of oxyethylenated glycerin, such as POE (polyoxyethylene) glyceryl triisostearate. The number of moles of ethylene oxide polymerized in the polyoxyethylene chain (PEG chain) is preferably 10 to 30, more preferably 15 to 25. When an isostearic acid triester is used, the number of moles of about 20 (PEG of triisostearic acid ( 20) Glyceryl) is particularly preferred. As described later, these are comparable to general refined vegetable oils in terms of safety to the skin.

  The oil-based shampoo composition of the present invention can further contain other components as long as the effects of the present invention are not impaired. Examples of such components include vegetable oils, animal oils, synthetic esters, nonionic surfactants other than the above, essential oils other than the above, vitamins, plant extracts, alcohols, polyols, fragrances, antioxidants , Anti-inflammatory agents, pigments and polypeptides. In order to keep the hair in a soft state after washing, the addition of a protein surfactant such as acylated hydrolyzed silk sodium is excellent and advantageous. As for the components to be additionally added as described above, an appropriate one can be selected by performing the above-described “wave search test” as necessary.

  One of the reasons why the invention of the present invention cannot be made using a patch test or the like that has been used conventionally is the fact that it is actually difficult to try many prescriptions with the human body. When atopic dermatitis becomes extremely worse, the pain and burden on the tester is very large. Therefore, in practice, surfactants that can be used have been selected based on safety measurements at the cellular level for presumably infinite prescriptions. However, the water-based shampoo solution thus obtained, when used by people with atopic skin, as described above, seems to have a clean scalp, rash, dandruff, etc., just after hair washing, as described above. However, it was getting worse as time went by one day or two days.

  By making the present invention as described above, the state of the sensitive scalp such as atopy can be directed to the daily improvement direction, and it is safe for the hair part to remain on the scalp for hours. The drug was born. This safe cleaning agent not only can be used for scalp massage safely, but can also radically improve the scalp environment in response to antioxidants and antibacterials. After washing with this detergent, it was only necessary to rinse off with water, and basically it was not necessary to use an aqueous shampoo, so the atopic scalp could be improved every day.

  The present invention is a gospel for patients with atopic dermatitis and provides a guideline for recovery from atopic dermatitis. In addition, it is a hair care system that does not basically use water-based shampoos and is safe and effective, and it does not require a large amount of water to be washed away, so it is economically and environmentally beneficial. is there. And since the time for washing away the shampoo liquid can be saved, and further, a relaxing effect in the massage action can be obtained at the same time, the effect obtained psychologically is more beneficial than ever before.

  By using the treatment liquid and treatment method of the present invention, it is possible to improve or prevent scalp inflammation, seborrhea, atopic dermatitis, etc., particularly in home hair care in the home, and prevent hair loss and health. Virtuous hair care that grows healthy hair can be realized. In addition, a shampoo system for nursing care that is safe and does not need to be washed away at the time of nursing care is enabled, and a person who receives a hair washing service for nursing care can also be relaxed by massage or the like.

  Since the hair part treatment liquid of the present invention does not have any adverse effect even if it is applied to the hair part for a while, it can be applied to the hair in advance to scrub the hair and massage the scalp. And even after leaving it for a while, it is possible to remove dirt from the scalp including pores by simply rinsing with a small amount of warm water. Basically, it does not require any normal foam shampoo, rinse or treatment.

  For example, take an appropriate amount in the living room or in the bathtub while taking a bath, apply it evenly to the scalp, and spread it while using the fingers of both hands. Although it may be applied only, massage with both fingers on the scalp not only promotes blood circulation of the scalp, but also applies oily shampoo itself to the scalp to physically remove scalp and pore dirt and dandruff This is necessary because it has the effect of Although the method of the massage is not particularly limited, it is preferable to apply a mass of 8 to 10 fingers to the scalp and move the scalp while holding the head part. Further, when one place is over, the method of moving the scalp while changing the place where the finger of the finger is applied is effective for the sensitive scalp and the inflamed scalp without giving any stimulus. This method is also effective for promoting blood circulation and removing keratin plug materials such as dandruff.

  This massage can be done by yourself, but it is usually preferred in the sense of skinship to have someone else massage. In particular, it is also preferable in terms of strengthening family bonds. Normally, when you become an adult, you do most of the shampoo while bathing yourself, but oil-based shampoo is difficult to drip during application, so it is a perfect way to do skin massage by doing hair massage in the room before bathing Become a material. Although it may be applied to the entire hair by hand after the massage, it is preferable to apply an oily shampoo to the entire hair using a brush or the like. In this way, it is excellent in the effect of applying a small amount to the entire hair, and is also excellent in hair washing and treatment effects economically.

  After massage, it is desirable to leave for 1 to 60 minutes, preferably 5 to 30 minutes, more preferably 10 to 15 minutes, and relax while smelling the scent of essential oil. By leaving it after the massage, the dirt naturally floats up, and this is a necessary process for effectively removing the scalp and pores in advance before washing with water.

  In addition, leaving it after massage can be relaxed psychologically by smelling the scent of essential oil, and is also effective for mental hair removal. In other words, providing a stage for an invisible mental effect that cannot be obtained with regular shampoos, with the skinship of having a massage for family and others, and the aroma effect of essential oils left after massage. It will be.

  After massaging and standing, washing with water (water is from room temperature to about 43 ° C.) is performed, but in the case of the present invention, the amount of rinsing water is usually 1/2 to 1/3. This is because dirt is sufficiently removed during massage, and excellent emulsification performance is exhibited by the lipophilic nonionic surfactant dissolved in the oil. Further, because of the excellent safety of the lipophilic nonionic surfactant used in the present invention, there is no problem even if it remains slightly. According to the conventional method, the shampoo washing itself is performed twice in a cold place in the winter, after going out of the bathtub, and a considerable number of washing steps are performed. In the case of a person with long hair, rinsing hot water about 5 to 15 times is performed, but this is physically fatigued, and the amount of water used is large, which is economically and environmentally burdensome.

  Foam washing with water-based shampoo, which has always been done, is usually unnecessary. When using foam washing with an aqueous shampoo, such as when it is very dirty, it is usually sufficient to wash only the hair while keeping the amount to less than half that required when using the shampoo. In this case, the purpose of washing can be achieved with less than half the amount of normal shampoo used, and at the same time, the foaming state is more effective than usual. This is because the oil-based shampoo of the present invention effectively removes dirt, and the difference in the amount of shampoo used is further widened compared with mere shampooing oil massage oil. 10 amount. Even in home care, the purpose of the oil-based shampoo of the present invention can be sufficiently achieved by washing with water. It can also be done. At this time, it is advantageous that the amount of shampoo itself used is reduced, foaming is increased, the amount of washing with water is reduced, and the tendency of the scalp to be deteriorated is reduced as compared with normal shampoo use.

  The hair care system of the present invention covers all of pore cleaning, scalp cleaning, blood circulation recovery, and safety that can be applied to the skin and can also serve as a skin protectant. Therefore, it was possible to remarkably improve the change in the scalp state after washing the hair, which has been taken for granted until now, that is, the cycle of changes such as inflammation and dandruff getting worse as the day passes without washing, With use, the condition of the scalp can be improved.

  The hair part washing treatment liquid of the present invention does not deteriorate the condition of the hair and scalp even if the hair is scrubbed and the scalp massaged, and then only wiped off with a steamed towel, without being washed away. And even if it is left without shampooing for several days, the state of the hair and scalp is maintained well and glossy. In particular, it is possible to give a life to the cared person from the joy of keeping the scalp and hair clean and good for the care recipient.

  In addition, after applying the hair washing treatment solution of the present invention to the hair, scrubbing the hair and massaging the scalp, leaving it for a while and then performing the washing-based treatment, the relaxation effect on the customer, promoting scalp blood circulation Effects such as hair growth effect and ease of treatment can be obtained.

  Hereinafter, examples and comparative examples of the present invention will be described using data in the drawings and tables.

<Evaluation of hypoallergenicity of compounding ingredients>
First, various vegetable oils, various essential oils, and nonionic surfactants (PEG (20) glyceryl triisostearate) as base components were evaluated by a nondestructive wave search evaluation method. The PEG (20) glyceryl triisostearate used here is one obtained by adding or condensing a polyoxyethylene chain having an average polymerization mole number of 20 and 3 molecules of isostearic acid to one molecule of glycerin.

  The evaluation was performed by measuring numerical values corresponding to each code with three skilled operators using a wave measuring device, and then averaging the numerical values. The evaluation results are shown in Table 1 below, and the evaluation values are viewed as follows.

+17 to +21 Excellent +11 to +16 Good +06 to +10 Standard +01 to +05 Caution −06 to −10 Caution −11 to −21 Strict Caution As shown in Table 1 below, cold compressed oil is used for hair loss, alopecia, and circular hair loss. Compared with refined vegetable oil, the evaluation for the scalp symptoms such as symptom and dandruff was much better. In addition, low-temperature compressed oil is also excellent in the evaluation of the skin disease “itch”, which is the most important factor when changing the scalp environment of atopic sensitive skin.

次に、上記成分を配合した各実施例及び各比較例の頭髪部洗浄処理液の組成（重量部）について下記表２〜３にまとめて示す。これら表には、各実施例及び各比較例における処理方法（番号に対応する内容は欄外に記載）についても、まとめて示す。 In addition, PEG (20) glyceryl triisostearate was the safety base of this time because it can be said to be as safe as general refined oil.

Next, the compositions (parts by weight) of the hair part washing treatment liquids of Examples and Comparative Examples in which the above components are blended are shown in Tables 2 to 3 below. These tables also collectively show the processing methods in each example and each comparative example (contents corresponding to numbers are described in the column).

以下に、各実施例及び比較例についての、評価方法及び評価結果について説明する。 In Example 9, the composition of Example 3 and “hypoallergenic shampoo solution 2” (composition of Comparative Example 2) described in the column were sequentially used. In Example 10, the composition of Example 6 and The “hypoallergenic shampoo solution 2” (composition of Comparative Example 1) described in the column was used in sequence.

Below, the evaluation method and evaluation result about each Example and a comparative example are demonstrated.

フケ指数：敏感肌、アトピー肌２０名の初期ふけ状態を観察し、下記表５に示すように、ふけ指数で数値化した。施術直後、１日後、２日後と１ヶ月後の変化値を求めた。頭皮スコアの場合と同様に、最初の２日間は何も頭皮や頭髪に施術はしていない。その後同じサイクルでの施術をくりかえし１ヶ月後の変化値を求めた。評価の結果を、図２に示す。

図１〜２に示すように、頭髪部状態は、全ての比較例において、最初の状態から１日後、２日後と変価値がプラスなので、状態が悪化する傾向になる。まず、水系シャンプーでの洗浄のみを行った比較例１〜２では、直後は頭皮やフケがきれいになったように見えるが、発疹が日をおうごとに悪化し、フケも日を追うごとに増えるため根本的な治療効果が考えられなかった。 <Observation of hair>
Scalp score: The initial scalp conditions of 20 sensitive skins and atopic skins were observed and quantified by stimulation index as shown in Table 4 below. Change values were determined immediately after treatment, 1 day, 2 days, and 1 month later. During the first two days, there was no treatment on the scalp or hair. Thereafter, the treatment in the same cycle was repeated every 3 days, and the change value after 1 month was determined. (Negative stimulation index change is better, positive is worse.)
The evaluation results are shown in the graph of FIG.

Dandruff index: The initial dandruff state of 20 sensitive and atopic skins was observed and quantified with the dandruff index as shown in Table 5 below. Immediately after the treatment, the change values after 1 day, 2 days and 1 month were obtained. As with the scalp score, there was no treatment on the scalp or hair for the first two days. Thereafter, the treatment in the same cycle was repeated, and the change value after one month was determined. The evaluation results are shown in FIG.

As shown in FIGS. 1 and 2, the hair portion state tends to deteriorate in all the comparative examples because the value of change is positive one day and two days after the first state. First, in Comparative Examples 1 and 2 in which only washing with an aqueous shampoo was performed, the scalp and dandruff seemed to be clean immediately, but the rash worsened with the sun and the dandruff increased with the sun. Therefore, the fundamental therapeutic effect was not considered.

  Comparative Examples 3 to 4 are examples in which a system of only a low-temperature compressed oil and an essential oil was used before or after washing with a water-based shampoo at a normal use amount. In Comparative Example 4 in which oil was applied before washing with an aqueous shampoo, the oil does not have self-emulsifying properties, and therefore it is necessary to perform considerable washing off with an aqueous shampoo. If the washing is insufficient, the hair and scalp will be sticky and cannot withstand actual use, increasing the amount of aqueous shampoo used. For this reason, stimulation increases. On the other hand, in Comparative Example 4 in which oil is applied after washing with an aqueous shampoo, it is at best to maintain a scalp state that is neatly prepared immediately after washing with an aqueous shampoo until the first day. This is because it is virtually impossible to apply a uniform amount to the entire scalp without sticking.

  In Comparative Examples 5-7, it is a case where the low-temperature pressing oil of this invention was changed into refined oil. In this case, the washability is ensured using a nonionic surfactant, but the scalp score is good only on the first day, but shows a worsening tendency on the second day. After one month, it gets worse. On the other hand, the dandruff index is not improving in all the comparative examples. This is considered to be because the natural components necessary for healing have been removed by a purification action such as chemical extraction or have been altered by exposure to high temperatures during the purification.

  In contrast to these comparative examples, surprisingly, in each of the examples, the state of the scalp and dandruff of the sensitive skin was improved every day, and after one month, the state was further improved. .

  In Examples 7 to 8, the hair was rinsed with two steamed towels without rinsing after massaging the hair part, but after rinsing with water after treatment with the same washing treatment liquid, Example 1 The condition of the hair portion was improved to the same extent or more than in the case of ~ 2. That is, it is known that the hair part treatment liquid and the treatment method of the present invention are particularly useful in the scene of care. With the method of the present invention, it is considered that psychological healing can be obtained with a relaxing effect with a psychological massage and a steam towel at an appropriate temperature, and mental improvement in a nursing situation that cannot be obtained by the conventional method is obtained. It is done.

  On the other hand, in Examples 9-10 in which washing with an aqueous shampoo was used in combination, the improvement effect tended to be smaller than in Examples 1-8 using only the treatment liquid of the present invention.

20 volunteers (those with atopic sensitive skin) are given hair care in a 3-day cycle, and when they are washed with water, they are netted in a bathroom and counted. The average number of people who lost hair after one month was measured. The result is shown in FIG.

  The result of FIG. 3 was almost the same as the state of the hair part of FIGS. For people with sensitive skin, the number of hair loss may be an appearance of the scalp, but inflammation scalp, itching and hair loss often occur as a set, and as a result, it is considered that the number of hair loss has been improved. However, regarding hair removal, comparative examples 1-2 and comparative examples 5-7 show a very slight improvement effect. Moreover, although the improvement effect was small compared with Examples 1-2 and 6-9, Examples 9-10 which used aqueous | water-based shampoo together were not very different from Examples 4-5.

<Evaluation of mental relaxation effect>
Sensory evaluation was performed about the effect after an actual use test by 20 persons.

＜スタイリング性評価＞
梅雨時、くせ毛の者２０名により、頭髪洗浄処理を行った後、ドライヤー使用及び不使用(ブラシ、くしは必要に応じて使用)の場合について、翌日のスタイリング保持感を評価した。評価は、下記のような基準で行った。この評価の結果を表７に示す。 The evaluation results are shown in Table 6 below. Evaluation criteria are shown in the lower column of the table.

<Styling evaluation>
In the rainy season, 20 hairy persons performed hair scrubbing treatment, and then evaluated the styling retention feeling of the next day for the cases of using the dryer and not using it (brushes and combs were used as necessary). Evaluation was performed according to the following criteria. The results of this evaluation are shown in Table 7.

表７の結果から明らかなように、全ての実施例において、ドライヤーの使用・不使用に拘わらず、良好なスタイリング性が得られた。すなわち、ドライヤーなしで、できるだけ直毛に近い状態で保持することが可能となった。 The next day's comb hair is barely visible. 4
The next day's hair is a little bit 3
The next day's hair has a shape 2
The next day, a lot of comb hair appears 1
The average number of people is 3 or more and less than 4 ◎
2 or more and less than 3
1 or more and less than 2 X

As is apparent from the results in Table 7, in all Examples, good styling properties were obtained regardless of whether or not the dryer was used. That is, it becomes possible to hold the hair as close to straight hair as possible without using a dryer.

  On the other hand, in any of Comparative Examples 1 and 2 using an aqueous shampoo and Comparative Examples 3 and 4 using washing and aqueous treatment in combination with an aqueous shampoo, the styling property was not sufficient. In addition, since the comparative examples 5-7 were the compositions similar to an Example except having used refined vegetable oil, the effect with respect to a styling property was favorable similarly to the case of an Example.

  The excellent styling retention effect is very significant as follows. First, for people with sensitive skin such as atopy, blow with a dryer and blow with daily styling have caused the scalp condition to deteriorate, but this can be avoided as much as possible. In addition, those who are not necessarily sensitive skin, who have non-straight hairs, hairs, etc., have difficulty in styling in rainy seasons and high humidity, and the heat of the dryer hurts the scalp. However, this can also be avoided.

<Evaluation of rinse off>
20 persons evaluated how many times it was necessary to wash off with a washbasin.

水での洗い流しが、実施例１〜６ではおおよそ２回くらいですんでいる。これは、界面活性剤が泡の立つものでないこと、すすぎ落ちに優れていること、及び、よくすすがなくても頭皮に悪影響をあたえないことが主原因である。また、実施例７〜８は蒸しタオル使用のため、水でのすすぎはゼロ回である。さらに、実施例９〜１０は、シャンプー使用量が１／３のため、すすぎが少なくてすんでいる。それにくらべて、比較例は、水系シャンプーをしっかりとすすぎ落とす必要があるため、４回以上となり、実施例の倍以上のすすぎ回数となる。 The evaluation results are shown in Table 8 below.

The washing with water is about twice in Examples 1-6. This is mainly due to the fact that the surfactant is not foamy, excellent in rinsing off, and does not adversely affect the scalp even if it is not rinsed well. Moreover, since Examples 7-8 use a steam towel, the rinse with water is zero times. In Examples 9 to 10, the amount of shampoo used is 1/3, so that rinsing is small. In contrast, in the comparative example, it is necessary to rinse off the water-based shampoo firmly, so that the number is four times or more, and the number of times of rinsing is more than double that of the example.

  Even in the embodiment, although the rinsing is necessary, the number of times of rinsing can be reduced, which is advantageous for keeping the scalp healthy. Although it is not known unexpectedly, even the water that is washed out during shampooing causes rough scalp for sensitive skin such as atopy. Therefore, for those with sensitive skin, rinsing properties are very important. In addition, the amount of water used is reduced, which is advantageous in terms of environment and economy.
