Description

Cosmetic composition for hair or scalp for enhancing volume of hair and use thereof

The present invention relates to a cosmetic composition for hair or scalp that enhances the volume of hair. More specifically, it relates to a cosmetic composition for enhancing the volume of hair, which comprises The hydrophobicity (Hydrophobicity) to exert the effect of increasing the fluffy feeling of the hair is a single hydrophobic polymer as an active ingredient, or a mixture of a hydrophobic polymer and a nonionic polymer is used as an active ingredient.

Hair is a thin and thin protein structure with an average thickness of about 0.07mm, and can be roughly divided into the hair shaft (Hair Shaft) exposed outside the skin and the hair root (Hair Root) inside the skin. The scalp has a basic structure and physiological function similar to the skin, and the hair follicle of the scalp is characterized by being more complex than other parts and having many sebaceous glands. The hair root is the part inside the hair follicle, which is the part buried in the scalp and has a depth of about 2~4mm. The very bottom of the hair root expands like a bead. This part is called the hair bulb (Hair Bulb), and the thickness of the hair depends on the size of this part.

Enlarging the cross-section of the hair, it can be seen that it is divided into three parts, namely, the innermost and central medulla (Medulla), the fur cortex (Cortex) that wraps the hair medulla, and the outermost cuticle (Cuticle) . The cuticle is a highly chemical-resistant part that covers the surface of the hair and wraps the inside of the hair. It is composed of epicuticle, exocuticle, and endocuticle from the outside. Consists of three layers. The fur cortex exists on the inner side of the cuticle and occupies most of the hair (85~90%). Its main component is keratin, which is composed of cortical cells and intercellular binding substances, and is hydrophilic and susceptible to hot dyeing. . The hair medulla exists in the center of the hair, with some melanin particles, and there are many large and small air bubbles in the medulla, so it contains air.

Generally, hair is composed of a protein called keratin, and specifically, hair is keratin containing 14 to 18% of cystine among 18 kinds of amino acids. These keratins are very strong proteins under mild conditions such as water or neutral solvents, but they are easily damaged by excessive physical and chemical treatments such as combing, heat during blow drying, dyeing, and perms. Recently, the hair is damaged due to physical, chemical or environmental factors such as frequent perms and dyeing, resulting in rough hair and loss of luster, resulting in reduced softness and flexibility, and increased friction This makes it difficult to manage the hair, and in addition to problems such as hair breakage or split ends, the hair becomes thinner and loses elasticity, leading to loss of vitality and drooping, thereby losing volume.

The fluffiness of the hair depends on the total area of the whole hair consisting of one or more strands covering (occupying) the skin. For example, given two people with similar head shapes and hairstyles, one with long hair length and one with short hair length, the person with the longer hair length will have a larger area of hair compared to the person with the shorter hair length , it can be said that the fluffy feeling of the hair is greater (the fluffy degree of the hair is high). In addition, the distance between the strands of hair constituting the braid (Hair Bundle or Hair Tress) is especially greater than that of the hair shaft at the end of the hair (hair tip) compared to the hair shaft near the hair root (hair shaft, hair shaft). The greater the spacing between hair strands, the more volume the hair will have. That is, a person who has a large overall area of hair on the skin and a large space between the hair strands of the braid is generally considered to have thicker hair because the volume of the hair increases.

In the case of hair, aging of the skin or hair due to aging of the skin, especially due to outdoor exposure to ultraviolet rays, or lack of components constituting the hair fiber and/or hair fiber structure due to chemical/physical damage The thickness of the hair fiber becomes thinner due to deformation and the like, and the strength of the hair fiber also becomes weaker, which tends to show a tendency for the hair to become less fluffy.

In particular, even among people with similar head shapes and hairstyles, the volume of the hair varies depending on the thickness and strength of the hair fibers. For example, if the strength of the hair fibers becomes weak, the hair growing from the The power to support the remaining hair until the end of the hair shaft where the hair root protrudes to the outside of the skin decreases. As a result, the hair as a whole "sags" and causes cosmetically negative sensations such as "looking less fluffy", "looking weak" and "aging the hair" Hair management, such as hairstyles, may also be difficult.

In order to maintain and enhance the volume of the hair, it is important to increase the elasticity of the hair. In particular, by strengthening the hair root (hair root) to enhance the elasticity of the hair, it is possible to give the effect of focusing on the overall hairstyle.

Hair can absorb 40% of the hair's weight in liquid/gas state water, and the moisture content of hair is mostly affected by the surrounding environment. For example, it is known that the moisture content of hair increases when it is exposed to an environment in which a high temperature continues, an environment in which pH changes greatly, an environment in which hydrogen bonds of hair are broken due to hair damage, and the like.

It is known that changes in hair hydration (Hydration) affect fiber elasticity (Fiber Elasticity). For example, it is known that when the water content of hair increases by 15-10%, the diameter of the hair (Thread) increases by about 0.5-1% (Maria et al., Brazilian jr of pharm., Vol45, n.1, 2009).

In particular, in terms of the chemical properties of the hair, the hair part near the scalp is different from the hair part far away from the scalp. The cuticle of the hair part near the scalp is in a complete state, but the tip part of the hair (Tip) It exists in a state with almost no cuticle (Bhushan et al., Progress in Materials Science, 53: 585-710, 2008).

In addition, in the case of compositions for cleaning hair or scalp represented by shampoo, its usual function is to cleanse hair and scalp, but recently, various products that have additional functions in addition to the original cleaning purpose are being released. Products, specifically, products under development include products that prevent hair from flying away after drying and improve softness by using silicon, and products that aim to organize and repair hair damaged by hair treatments such as coloring or perming Wait. However, although existing products use silicon to provide conditioning effects such as softness, moisturization, flexibility, and ease of combing, for hair with weak elasticity such as thin hair or damaged hair, it will make the hair less elastic. Too much sagging and drooping have problems in imparting a fluffy feeling to the hair. In order to solve such problems, research has continued on hair cosmetics for improving the softness of hair and restoring and strengthening damaged hair during or after washing. As a result, various methods for imparting a strong and sustained hair conditioning effect have been tried and developed, and have been put into practical use.

According to the prior art, there are examples of using hair coating ingredients in cleansing/hair growth products to express or appeal for the fluffy feeling of the hair in terms of cosmetics, but there is no clear report on what specific ingredients are used to form the fluffy hair feel. In addition, in existing hair cosmetic compositions, polyquaternium-11, polysilicon, polyurethane, etc. have been used alone to impart volume to hair, but the effect of enhancing volume has not yet reached a satisfactory level.

Against this technical background, as a result of continuous efforts of the present inventors to develop an external preparation composition for hair that improves the condition of hair such as fluffy hair, it differs from conventional cosmetic compositions for coating hair (for example, shampoo, hair conditioner, etc.), using the present invention comprising a single hydrophobic polymer as an active ingredient, or a mixture of a hydrophobic polymer and a nonionic polymer as an active ingredient, preferably containing isododecane /Butyl Acrylate/Hydroxypropyl Dimethicone Acrylate Copolymer, Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer and Polyquaternium -55 When the mixture of the hydrophobic polymer and the polyquaternium-11 as the nonionic polymer is used as the cosmetic composition for enhancing the fluffy feeling of the hair as an active ingredient, it is confirmed to have the following effect, that is, the effect of the fluffy feeling of the hair While the formation is improved (increasing the fluffy feeling of the hair), the elastic feeling of the hair on the top of the head becomes rich, and the hair residue feeling of the cosmetic composition is improved, and the finish coating feeling of the hair is improved, thereby completing the this invention.

detailed description

Below, the present invention will be described in more detail by means of examples. These examples are only for illustrating the present invention, and should not be construed as limiting the scope of the present invention to these examples, which is obvious to those skilled in the art.

Example 1: Confirmation of the number of strands of tresses suitable for the efficacy evaluation of improving the volume of hair with a small amount of test substance

The amount of conventional tress (tress) used in the evaluation of hair dosage forms is large, so the waste of raw materials used in the evaluation of dosage forms is serious, and it is difficult to evaluate the fluffy feeling of hair between tresses. The hair braids that are suitable for the evaluation of the efficacy of improving the volume of hair with the test substance (raw material).

First, BMAS-AP (Isododecane/Butyl Acrylate/Hydroxypropyl Dimethicone Acrylate Copolymer) that imparts a fluffy feel to different hair strands number of braids to process, then measure hair The distance from the start point (point) at which the braids are inclined to an angle of 45° is confirmed to confirm whether the hair volume is enhanced, thereby confirming the hair volume of the hair braids suitable for the evaluation of the level of enhancing the hair volume by a small amount of the test substance. number of wires. The specific test method is as follows.

(1) Use quick-drying glue to glue the hair part about 1 cm from the end of the hair root in the black hair with a length of about 25 cm, so as to make 5, 10, 20, 40, 80 and 100 hair parts respectively. Long braids made up of strands ([Option 1]: Decolorize the hair except for the 4~6cm of the hair shaft (hair shaft) that protrudes from the hair root to the outside of the skin (hair shaft part of 5cm) (Treat with a decolorizing agent (the first dose: the second dose = 3: 1) for 30 minutes). The original fluffy feeling of the braids can be reduced by the decolorization treatment, and the hair treated with the test substance can be more clearly confirmed, especially In the hair shaft part of the hair, whether the fluffy feeling of the 4~6cm hair part close to the hair root increases or decreases; [Option 2]: For the end of the braid, which is the end part of the hair shaft protruding from the hair root to the outside of the skin The tip region is dyed. By dyeing, the hydrophilicity (Hydrophilicity) of the end part of the braid becomes higher, and relatively speaking, the hydrophobicity (Hydrophobicity) of the hair part close to the hair root becomes higher, so that it is possible to accurately The effect of the hydrophobic/hydrophilic properties of the hair region close to the hair root on the volume of the hair was evaluated).

(2) After treating the hair shaft of long braids about 5 cm from the end of the hair root with an appropriate amount (for example, 2 g) of the test substance (control group: distilled water), rub it about 20 times and apply it (refer to FIG. 2 ).

(3) After washing the hair shaft part of the dreadlock coated with the test substance with running water and completely drying it (using a hair dryer), leave it at room temperature (18-25° C.) for about 30 minutes.

(4) Complete the step (3), then make the braid parallel to the horizontal plane, and fix it so that the hair shaft part (protruding from the hair root of the skin or scalp to the outside of the skin) will be 4 to 6 cm from the end of the hair. In the hair shaft part of the 4~6cm hair part close to the hair root) (the outer side of the part where the adhesive is present) was used as the starting point O.

(5) Let it incline naturally to the horizontal plane, record the point (A) forming an angle of 45° with the horizontal plane, and measure the point (A) as the starting point O at the hair shaft position to form a 45° angle with the horizontal plane ) length (O-A), thereby confirming the number of strands of tresses suitable for the evaluation of the fluffy feel of the hair.

As a result, as shown in Table 1 and Figure 3, compared with the braids treated with distilled water, the O-A length of the braids treated with BMAS-AP was shown to be longer as a whole, thus showing that it can also be seen by the naked eye. It is most beneficial to confirm the change in the fluffy feeling of hair clearly, especially when the number of hair strands is 100 to less than 150.

The number of strands of braided hair was set to 100, and the level of increase or decrease in the fluffy feeling of hair was evaluated for 7 kinds of raw materials among the test substances in Table 2 below.

As a result, as shown in the following Table 3, it was confirmed that isododecane/butyl acrylate/hydroxypropyl dimethicone acrylate copolymer (BMAS-AP) has the most excellent effect of improving the fluffy feeling of hair, Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer (KSP-101), Acrylates/C10-30 Alkyl Acrylate Crosspolymer (SC-200 ), polypropylsilsesquioxane/isododecane (DC680), etc. are also excellent in the effect of improving the volume of hair.

[Reference Example 1]: Establishment of an evaluation method for hair volume using braids and a screening method for substances that increase hair volume

The shape of the human head is a gentle oval, so except for the top part of the head, there are various inclinations formed by the hair growing from the pores. For example, when a person stands at attention, the inclination (angle) between the skin on the top of the head and the hair (hair root) is 90°, but the inclination between the skin on the side of the head or the skin on the back of the head and the hair (hair root) is 90°. close to 0°. Therefore, in order to evaluate the volume of hair using braids, it is necessary to consider the inclination formed by the scalp surface and the hair. The inclination of the hair needs to consider the influence of the position of the hair, the point where the inclination (bend) starts, and the length from the hair root to the point where the bend starts. In addition, the volume and weight of the hair will inevitably be affected by the overall volume and weight of the hair, so it is necessary to take these factors into account.

[Evaluation Method 1 for Fluffy Hair Feeling]: Evaluation Method for Fluffy Hair Feeling in the Hair Shaft Area Close to the Scalp

First, an evaluation method for the fluffy feeling of the hair in the hair shaft region close to the scalp was established.

(1) Based on the results of Test Example 1, the number of strands of braids was set to 100.

(2) As a result of confirming the appropriate point for fixing the braid, it is preferable to adhere and fix the hair part at a position about 1 cm from the hair root in the hair shaft part of the braid on a flat plate so that it can be fixed with the braid. The ground (horizontal plane) forms a right angle.

(3) As a result of confirming the angle of inclination capable of minimizing the spreading effect caused by the volume and weight of the hair itself, it is preferable to make the tresses form an angle of about 45° with the horizontal plane.

(4) When the braid forms an angle of about 45° with the horizontal plane, start from the inner hair part about 1 cm away from the end of the hair root of the braid, and use the inner hair part as a reference point (1), measure to the length (RS1) of the inner hair part of the tress (reference point (2)) lying on the extension of the direction parallel to said horizontal plane,

(5) measuring the length (RS2) of the outer hair portion of the tress (reference point (3)) from the reference point (2) to the extension of the tress in the vertical direction of the reference point (2),

(6) Calculate the bulkiness RS3 (=RS2/RS1) of the hair, so that the change in bulkiness of the hair portion of 4 to 6 cm close to the hair root can be remarkably confirmed in the hair shaft (see FIG. 4 ).

[Evaluation Method 2 for Fluffy Feeling of Hair]: Evaluation Method for Fluffy Feeling of Overall Hair

A method for evaluating the bulkiness of the overall hair has been established.

(1) The number of strands of braids was set to 100 in the same manner as in the evaluation method 1 of the fluffy feeling of hair.

(2) Place the braid on a horizontal surface with the root of the hair facing up.

(3) Define a specific hair position (point).

R0: 0.5-1.5 cm from the end of the hair root of the braid to the starting point of the hair stem (hair shaft), preferably 0.8-1.2 cm, more preferably 1 cm; R1: the distance from the R0 1.8~2.2cm, preferably 1.9~2.1cm, more preferably 2cm; R3: the distance from R0 is 2.5~3.5cm, preferably 2.8~3.2cm, more preferably 3cm point; M6: the distance from the R0 is 5.5~6.5cm, preferably 5.8~6.2cm, more preferably 6cm; and M9: the distance from the R0 is 8.5~9.5cm, preferably 8.8~ 9.2 cm, more preferably 9 cm points.

(4) In order to show the overall change in the fluffy feeling of hair caused by the test substances, the following index values were calculated.

dR: the value of subtracting the diameter of the braid at point R1 from the diameter of the braid at point R3; and dM: subtracting the braid at point M6 from the diameter of the braid at point M9 The value of the diameter.

From the above-mentioned dR and dM values, it is possible to remarkably confirm the change in volume of the 4-6 cm hair part close to the hair root and other hair parts in the hair shaft part (refer to FIG. 5 ).

Test Example 2: Confirmation of the Effect of Enhancing the Fluffy Feeling of Hair According to Evaluation Methods 1 and 2 of the Fluffy Feeling of Hair of the Present Invention

According to the evaluation methods 1 and 2 of the above-mentioned fluffy feeling of hair, 6 kinds of raw materials (BMAS-AP, KSP-101, Styleze W-10, ADM 8301 E, BELSIL PF 200 and SC- 200) The evaluation of the level of increase and decrease in the fluffy feeling of hair and the sensory evaluation of the feeling of use are carried out. Among them, the hydrophobicity (Hydrophobicity) index used when evaluating the level of increase or decrease in the fluffy feeling of hair is measured and shown by the following method, that is, after the processing (and washing) of each raw material using a pipette Distilled water (approximately 50 μl) was dropped on the braids of the hair, and the time (s) required for the distilled water to be completely absorbed was measured in seconds at the hair root and hair tip of the hair.

The sensory evaluation of the use feeling of the braids is based on the sensory score of a professional panel, and is evaluated by roughness, residual feeling and coating feeling, and each value is based on a 5-point evaluation score. Evaluation ([1] roughness: 0 points - no rough feeling, 5 points - very rough feeling; [2] residual feeling: 0 points - no residual feeling, 5 points - strong residual feeling; [3] coating feeling: 0 points - no coating feeling, 5 points - strong coating feeling).

As a result, as shown in Table 4, it was confirmed that BMAS-AP, KSP-101, Styleze W-10, and SC-200 are suitable for improving the fluffy feeling of hair based on the criteria of Evaluation Method 1 and Evaluation Method 2 above. and achieved a satisfactory level in terms of usability.

With reference to Table 4, it was confirmed that BMAS-AP, KSP-101, Styleze W-10, and SC-200 whose RS3 value was 1 or more according to evaluation method 1, the bulkiness of the hair part of 4~6 cm close to the hair root High, for distilled water with RS3 value less than 1, ADM 8301 E, BELSIL PF 200, the volume of the hair part close to the hair root 4~6cm is low.

In addition, for BMAS-AP, KSP-101, Styleze W-10, and SC-200 whose dR value was 10 or more according to the evaluation method 2, the bulkiness of the hair part of 4~6 cm close to the root of the hair showed a remarkable bulkiness. For ADM 8301 E and BELSIL PF 200 with a dR value of less than 10, the effect of increasing the volume of the hair in hair parts other than the hair part of 4 to 6 cm close to the hair root was shown to be large. This result is also consistent with the results in Table 3.
