Description

Transparent makeup remover

The invention relates to a transparent makeup remover.

On the market, there are water-based makeup removers (water-based makeup removers) that are formulated with surfactants for the purpose of removing sebum, dirt or oily cosmetics from the skin, and remove makeup dirt through the action of surfactants; Or oil-based makeup removers that mainly contain oily ingredients such as oils and remove oily cosmetics and oily dirt through the dissolution of oily ingredients (oil-type makeup removers); emulsions (multiphase) that are made by emulsifying water and oil into white turbidity ) type makeup remover.

Oil-based makeup removers are generally excellent at cleaning oily cosmetics such as lip gloss and foundation. However, they tend to be inferior to water-based makeup removers in terms of performance in removing film-forming mascara, etc. In addition, oil-based makeup removers take time to rinse off, and may leave an unpleasant greasy feeling on the skin due to the oil contained in the oily ingredients remaining on the skin.

On the other hand, water-based makeup removers have excellent rinsing performance, but have been criticized for their poor cleaning power against oil-based cosmetics that have excellent durability (makeup-lasting effect) such as waterproof types.

Furthermore, it is known that emulsified (multiphase) type makeup removers, which are made by emulsifying water and oil into white turbidity, may cause separation in the future. Moreover, oil-in-water emulsified types have low cleaning performance because they are emulsified, and oil-in-oil emulsified types have low cleansing performance. The water-emulsified type has low flushing performance.

The present inventor has completed the invention of a cleansing oil (Patent Document 1). The cleansing oil contains component A: a diester of a branched chain fatty acid with a carbon number of 14 to 22 and a polyglycerol, and an unsaturated polyglycerol with a carbon number of 14 to 22. Either or both diesters of fatty acids and polyglycerol, component B: esters of fatty acids with a carbon number of 6 to 10 and polyglycerol, and the ratio of the degree of polymerization of the polyglycerol to the number of bonds of the fatty acid (= polyglycerol) A substance in which the degree of polymerization of glycerin/the number of bonds of fatty acids) is 2.0 or more and 4.0 or less. Component C: diester oil selected from glycols and branched chain fatty acids, triester oils of glycerol and branched chain fatty acids, and dicarboxylic acids. One or more of the group consisting of diester oils of branched aliphatic alcohols. Component D: hydrophilic compound. This cleansing oil is a cleansing oil that exhibits high cleaning power even when mixed with water, has excellent rinseability after cleansing, and has an excellent greasy feel that does not easily leave oil. However, since this cleansing oil is an oil-type oily makeup remover, it tends to have poor cleaning power against film-forming type cosmetics (film-type mascara, etc.).

Clear makeup removers are loved for their beautiful appearance. From a technical point of view, in makeup removers that contain oil and water, transparency means that they are stable in a uniform single-phase state. Since emulsification does not occur, it is expected that its cleaning performance will be improved compared to emulsified makeup removers.

Among them, each company proposes a transparent makeup remover that allows oil and water to coexist.

As for transparent makeup removers in which oil and water coexist, for example, Patent Document 2 and Patent Document 3 disclose makeup removers in which the water content is 15 mass % or less and the proportion of oil is high. In terms of cleaning performance, it is similar to oil-based makeup removers. It has high cleaning performance for oily cosmetics, but it is not relatively easy to rinse off.

Patent Document 4 and Patent Document 5 disclose transparent makeup removers with a compounding amount of oil agent of 10% by mass or less and a high proportion of water. In terms of cleaning performance, it is similar to water-based makeup removers, and is easy to rinse, but the cleaning effect is relatively insufficient.

Patent Documents 6 to 9 disclose the preparation of a large amount of a nonionic surfactant, or the preparation of a large amount of a monohydric alcohol having 2 to 5 carbon atoms, a glycol such as butylene glycol or dipropylene glycol, polyethylene glycol or polypropylene glycol. Alcohols or derivatives of these compounds are used as surface-active additives in transparent makeup removers. Although makeup removers containing a large amount of these ingredients have improved cleaning power and tend to be easier to rinse off, they may cause irritation or dryness to the skin, eye irritation during use, and excessive degreasing of the skin. And it affects the moisturizing feeling after washing.

Furthermore, in order to make the makeup remover appear uniformly transparent, in addition to the balance of water and oil, and the selection of surfactants, when formulating polyols, it is also important to study the selection and dosage of polyols. That is to say, since not all polyols can be used for formulation, formulators need to spend more effort to design transparent and stable formulas. However, it is still not possible to obtain a substance that meets all the requirements of transparency, stability, cleaning power, and safety at the same time.

In addition, in water-containing makeup removers, it is necessary to take antiseptic measures for the composition. However, in recent years, so-called preservatives such as parabens, which are widely used in cosmetics, have gradually become unacceptable to consumers because they may cause irritation to the skin. Therefore, there is a search for makeup removers that are paraben-free and safe for skin or eyes.

The present invention imparts antibacterial properties to makeup removers, which is important in terms of quality design.

In makeup removers containing ingredients (A) to (E), parabens, etc. can also be blended. However, in order to dissolve parabens in water, heating is performed to dissolve the parabens. However, depending on the storage conditions, there is a risk that the parabens dissolved by heating may crystallize. Furthermore, since makeup removers rub the skin when used, the precipitation of solid substances that may damage the skin, such as parabens, significantly degrades the quality. In addition, preservatives such as parabens are ingredients whose safety to eyes or skin is questionable. Therefore, the makeup remover of the present invention contains at least one type of (F) antibacterial polyol that is highly safe and has no crystallization.

The antibacterial polyol as component (F) is preferably blended and selected from the group consisting of 1,3-butanediol (hereinafter referred to as BG), dipropylene glycol (hereinafter referred to as DPG), and 1,2-pentanediol (hereinafter referred to as DPG) be one or more of pentylene glycol).

In the transparent makeup remover of the present invention, when one or more types selected from BG, pentanediol, and DPG are contained as component (F), the content ratio of component (F) to component (D) is particularly important. As mentioned above, component (D) functions as a surfactant in the makeup remover of the present invention and is effective in improving the solubility of water and oil. Contributes to the transparency and temperature stability of makeup removers. On the other hand, BG, pentylene glycol, and DPG as components (F) cannot replace the solvent function of the oil represented by component (D). On the contrary, they may cause white turbidity in the makeup remover, so caution must be taken. determine its content.

It is less preferable that the component (F) is contained in the same amount as the component (D), or in an amount greater than the component (D).

Regarding component (D) and component (F), it is preferable that the two components are contained in a mass ratio such that (D):(F)=10:9.4 to 100:1, more preferably 10:9 to 100:1, preferably 10:8 to 100:1, particularly preferably 10:7 to 100:1.

If component (F) is contained in the above manner, the effect of containing component (D) can be achieved, that is, it can become a transparent makeup remover that stably coexists water and oil, is transparent and has excellent temperature stability, and has a high cleaning effect. It can impart appropriate antibacterial effect to the composition. If it exceeds this range, the component (F) may destabilize the composition and cause white turbidity or separation.

At this time, it can be judged that the makeup remover does not meet the purpose of the present invention. However, they were still implemented in a constant temperature room of 5°C, 25°C, 40°C, and 50°C. Storage stability test.

(b) Appearance after stability test (transparency, separation)

When the makeup removers of Examples 1 to 18 were stored in constant temperature chambers of 5°C, 25°C, 40°C, and 50°C for 1 month and then taken out to evaluate the transparency, all the makeup removers maintained transparency. On the other hand, the makeup removers of Comparative Examples 1 to 3 and Comparative Example 5 all showed separation after being stored in any temperature range of 5°C, 25°C, 40°C, and 50°C for one month.

If the compositions of Examples 1 to 18 are compared with the compositions of Comparative Examples 3 to 7, the compositions of Comparative Examples 3 to 7 contain polyhydric alcohol BG or DPG in place of the polyhydric alcohol component (D) in Examples 1 to 18. The composition of alcohol is glycerol, diglycerol and polyglycerol. However, the makeup remover becomes cloudy or separates immediately after preparation of such a composition. That is, it was found out that in order to make the makeup remover of water, oil and surfactant transparent, it is necessary to contain glycerin, diglycerin and polyglycerol which are components (D) of polyols like the compositions of Examples 1 to 18.

In addition, it was found that although polyols are contained in makeup removers containing water, oil, and surfactants, when only BG and DPG are contained, white turbidity or separation will still occur, which will hinder the transparency and stabilization of the composition. No benefit (refer to the appearance evaluation immediately after preparation of Comparative Examples 3 to 7).

In addition, Comparative Examples 1 to 7 contain the components (A), (B), (C), and (E) and do not contain the component (D). Among them, Comparative Examples 1 and 2 have compositions that do not contain BG or DPG. On the other hand, the compositions of Comparative Examples 3 to 7 contain BG or DPG. If the appearance evaluation results of such compositions are compared immediately after preparation, Comparative Examples 1, 2, 3, and 5 continue to be white and turbid, while Comparative Examples 4, 6, and 7 are separated immediately after preparation. status.

On the other hand, although Examples 1 to 18 contained BG or DPG, no clouding or separation occurred in the transparency and storage stability tests immediately after preparation. That is, it was found that the transparency and storage stability are excellent. In the embodiment, the mass ratio of the two components (D) and (F) is in the range of (D):(F)=10:9 to 20:5.

<Rinsing performance (measurement of volume standard average particle size of emulsified particles>

Table 1 shows the volume standard average particle diameter of the diluent emulsified particle diameter measured for the makeup removers of Examples 1 to 14 and 18. The minimum value is 66.7nm (Example 9), and the maximum value is 244.2nm (Example 12). Half of the 15 cases measured, 8 cases (Examples 2, 3, 4, 5, 9, 10, 11, and 18), found that "if the emulsified particle size is 100 nm or less, it can be rinsed off more quickly." Evaluation. In addition, the remaining 7 examples (Examples 1, 6, 7, 8, 12, 13, and 14) also received the evaluation "If the emulsified particle size is 101 to 300 nm, they can be rinsed off quickly."

<Ease of rinsing (sensory evaluation)>

The evaluation results of the sensory evaluators are shown in Table 1.

All the makeup removers of Examples 1 to 18 received an evaluation of "○: no oily feeling remains on the skin and they are easy to wash off." The result of easy flushing (sensory evaluation) is consistent with the determination result of the volume standard average particle size.

<Evaluation of cleaning power (evaluation of ease of removal of makeup dirt based on sensory evaluation)>

Table 1 shows the evaluation results of the ease of removal of lipstick, waterproof eyeliner, and film-type mascara.

All the makeup removers of Examples 1 to 18 were evaluated as "○", and it was confirmed that the evaluation of "almost completely removing makeup dirt" was obtained.

<Preservation efficacy test>

According to the test based on the standards of the Japanese Pharmacopoeia, it was determined that there was a "reduction" in any of Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus, and it was judged that there was no problem.

<Evaluator Test>

When the makeup removers of Examples 9, 10, 13, and 14 were given to 20 female reviewers and asked to conduct the reviewer test (home test) at their own homes, the reviewers had no sense of cleaning power at all. Regarding the dissatisfaction, in the opinion column, it received a very high rating that it can remove any type of mascara, waterproof eyeliner, foundation, and lipstick well. Additionally, there were no reported cases of skin or eye irritation.

There are various types of beauty cosmetics on the market, and the choice depends on consumers' preferences. The transparent makeup remover system of the present invention is stably prepared with water in advance, so no matter what type of beauty cosmetics the consumer chooses to use, or no matter what usage scenario the consumer is in (bathroom where there is a high risk of water contamination/no contamination) When performing cleaning actions (makeup removal) in indoor areas where water is a concern, you can achieve excellent and stable cleaning effects. Particularly in the conventional technology, eye makeup that is difficult to remove has to be removed using a makeup remover specifically designed for removing eye makeup, and a separate makeup remover is used to remove makeup from the entire face, which is a complicated makeup operation. Ran However, with the makeup remover of the present invention, all different types of cosmetics can be removed with just one makeup remover. Such a cleaning effect is unimaginable with conventional makeup removers, and the invention that achieves this effect is an epoch-making invention.

In addition, the makeup remover of the present invention has a transparent and stable appearance even if it contains an antibacterial polyol. In addition, it has low irritation to the eyes or skin, so it is highly safe.

"Examples 19 to 27, Comparative Examples 14 to 15"

The optimal blending amount of water as component (E) of the present invention was studied in detail. A detailed description will be given below showing a test and results of a comparative study based on the compositions of Examples 19 to 27 and Comparative Examples 14 to 15 (Table 3).

1. Preparation of makeup remover

Makeup removers having the compositions of Examples 19 to 27 and Comparative Examples 14 to 15 (Table 3) were prepared according to conventional methods.

2. Evaluation test methods

Each makeup remover was evaluated by the same test method as the test performed on the makeup removers of Examples 1 to 18 and Comparative Examples 1 to 13.

The following test items were implemented: "<Appearance observation (transparency)>, (a) Appearance immediately after preparation, (b) Appearance after stability test (stability)", "<Rinseability (volume standard average of emulsified particles) "Measurement of particle size)", "<Ease of rinsing (sensory evaluation)>", "<Evaluation of cleaning power (evaluation of ease of removal of makeup dirt based on sensory evaluation)>".

3. Evaluation results

The evaluation results are shown in the lower part of Table 3 below.

[table 3]

Examples 19 to 27 have the following transparent makeup remover compositions: 7 to 9.6 mass % of (A) component, 6.4 to 9 mass % of (B) component, 23.4 to 44 mass % of (C) component, 8 (D) component to 25 mass %, (E) component to 15 to 44.99 mass %, and (F) component to 5 to 8 mass %.

On the other hand, Comparative Example 14 contains 9.6 mass% of (A) component, 6.4 mass% of (B) component, 44 mass% of (C) component, 25 mass% of (D) component, 5 mass% of ( F) component, 10% by mass of (E) component. In addition, Comparative Example 15 contains 9.6 mass% of (A) component, 6.4 mass% of (B) component, 20 mass% of (C) component, 9 mass% of (D) component, and 5 mass% of (F) Component, 50% by mass of component (E).

<Appearance observation (transparency)>

(a) Appearance immediately after preparation

All the makeup remover systems of Examples 19 to 27 have a transparent appearance. In addition, the makeup remover of Comparative Example 14 is also transparent. On the other hand, the appearance of Comparative Example 15 immediately after preparation was cloudy and opaque. The samples of Examples 19 to 27 and Comparative Example 14 were subjected to a stability test stored in a constant temperature room at 5°C, 25°C, 40°C, and 50°C.

(b) Appearance after stability test (stability)

When the makeup removers of Examples 19 to 27 and the makeup remover of Comparative Example 14 were stored in a constant temperature room at 5°C, 25°C, 40°C, and 50°C for 1 month and then taken out and evaluated for transparency, all the makeup removers were Transparency maintained.

<Rinsing performance (measurement of volume standard average particle size of emulsified particles)>

Table 3 shows the volume standard average particle diameter of the emulsified particle diameter measured for the makeup remover of Examples 19 to 27 and the makeup remover of Comparative Example 14. Among the nine tested examples, two (Examples 21 and 25) received the evaluation "If the emulsified particle size is 100 nm or less, the water can be rinsed off more quickly." In addition, the remaining seven examples (Examples 19, 20, 22, 23, 24, 26, and 27) and Comparative Example 14 also obtained "If the emulsified particle diameter is 101 to 300 nm, the volume standard average particle diameter of the emulsified particles is It can be rinsed off quickly."

<Ease of rinsing (sensory evaluation)>

The evaluation results of the sensory evaluators are shown in Table 3.

All the makeup removers of Examples 19 to 27 and Comparative Example 14 received an evaluation of "○: No oily feeling remains on the skin, and it is easy to wash off." The result of easy flushing (sensory evaluation) is consistent with the determination result of the volume standard average particle size.

<Evaluation of cleaning power (evaluation of ease of removal of makeup dirt based on sensory evaluation)>

Table 3 shows the evaluation results of the ease of removal of lipstick, waterproof eyeliner, and film-type mascara.

The makeup removers of Examples 19 to 27 were all evaluated as "○", and it was confirmed that makeup dirt was almost completely removed. However, the makeup remover of Comparative Example 14 was unable to remove dirt from the film-type mascara, and the test received a "×" evaluation.

The following conclusions can be drawn from the above test results.

That is, it is clear from the fact that the makeup remover of Comparative Example 14 cannot remove film-type mascara. In order to remove film-type mascara dirt, the content of water as component (E) must exceed 10 mass %.

In addition, judging from the fact that Comparative Example 15 was cloudy immediately after preparation, it is believed that the content of water as component (E) must be less than 50% by mass in order to avoid cloudiness in the makeup remover.

On the other hand, Examples 19 to 27 were transparent immediately after preparation and were also transparent after the storage test. In the sensory evaluation, the ease of rinsing and the cleaning effect based on the sensory evaluation were evaluated as "○". This effect is thought to be due to the fact that the water content of component (E) is in the range of 15 to 44.99% by mass.

"Quantitative evaluation test on the cleaning power of waterproof eyeliner and film-type mascara"

In order to accurately measure the cleaning power of the makeup removers having the compositions of Examples 21 to 27 and Comparative Example 14 for waterproof eyeliner and film-type mascara, quantitative cleaning power measurements were performed (refer to Figures 1 and 2 for the results).

<Test method>

In this test, the cleaning rate of beauty cosmetics was calculated based on the color difference, and the cleaning power was evaluated.

(Calculation formula for cleaning rate of beauty cosmetics)

Color value of white artificial leather before application of beauty cosmetics (hereinafter referred to as "beauty") using a colorimeter (device name: CM-2600d, manufactured by Konica Minolta Co., Ltd.) 1. Test after application of beauty cosmetics The color value 2 of the test object and the color value 3 of the test object after cleaning with the test sample are measured, and the color difference (ΔEa; color difference before and after coating, ΔEb; color difference before and after cleaning) is calculated from the measured values Color difference), and further calculate the makeup cleansing rate (%) according to the following calculation formula.

In addition, △E=(△L ² +△a ² +△b ² ) ^1/2 .

Beauty cleansing rate (%) = △Eb/△Ea×100

The higher the beauty cleansing rate (%) value, the higher the cleaning power.

Specifically, it is implemented as follows.

<Cleaning power evaluation method>

(1) Apply 0.005g of waterproof eyeliner or film-type mascara within a diameter of 1cm on a 3cm×6cm piece of white artificial leather that has been previously measured for color value 1 and dry for 30 minutes. Use this as the test object.

For waterproof eyeliner, use Maybelline New York’s Master Liner Creamy Pencil BK-1.

Also, as a film-type mascara, use Attenir’s Perfect Mascara r21.

(2) Use a colorimeter (device name: CM-2600d, manufactured by Konica Minolta Co., Ltd.) to measure the color value 2 of the prepared test object.

(3) Drop 0.1 ml of the test sample onto the test object produced in (1) above, and wipe it with your finger 20 times at a rate of once per second.

(4) Fully rinse the test object with water and dry it.

(5) Use a colorimeter to measure the color value of the dried test object 3.

(6) Based on the calculation formula of the aforementioned makeup cleansing rate, calculate the cleaning rate (%) of waterproof eyeliner or film-type mascara.

． Determination test results of cleaning power

The test results of the cleaning power of waterproof eyeliner or film-type mascara are shown in Figures 1 and 2.

As shown in Figure 1, for waterproof eyeliner, the makeup removers of Examples 21 to 27 and Comparative Example 14 all have high cleaning performance of more than 80%.

On the other hand, regarding the film-forming mascara that formed a film, it was confirmed that there was a large difference in the cleaning power between the Examples and the Comparative Examples. That is, as shown in FIG. 2 , Examples 21 to 27 all exerted a cleaning effect of more than 80% on the film-forming mascara, indicating a strong cleaning effect. Comparative Example 14 has extremely low cleaning power for film-type mascara, with a cleaning power of less than 10%. The test results are very consistent with the sensory test results.

As shown above, from the test using Examples 21 to 27 and Comparative Example 14, it is clear that in order to wash off the film-type mascara, in the makeup remover of the present invention, the amount of water of component (E) relative to the total amount of the makeup remover is The content must exceed 10% by mass. In addition, in order to maintain transparency and stability due to storage, it was found that the optimal content of water in component (E) is 13 to 47% by mass, and more preferably in the range of 15 to 45% by mass.

"Study on the maximum content of component (F) (Study based on Comparative Examples 16 to 31)"

In order to confirm the maximum content of the antibacterial polyol of component (F) of the present invention, studies were conducted based on the compositions of Comparative Examples 16 to 31 (Table 4). Show the test results and explain.

1. Preparation of makeup remover

The makeup removers of Comparative Examples 16 to 31 (compositions in Table 4) were prepared by conventional methods.

Comparative Examples 16 to 29 are those in which the content of components (A) to (E) is adjusted so that the content of the makeup remover of the present invention falls within a range suitable for it, and the content of the antibacterial polyol of component (F) is adjusted. to a composition of 10 to 30% by mass. In addition, in order to increase the content of the antibacterial polyol, the content of cetyl ethylhexanoate as component (C), glycerol as component (D), and water as component (E) is appropriately increased or decreased within the allowable range. Preparation.

In addition, the content of components (A) to (D) in Comparative Examples 30 and 31 is set to an appropriate content based on the composition of the makeup remover of the present invention, but the composition is reduced to the content of water that becomes component (E). 10% by mass, and the BG or DPG of component (F) was adjusted to 30% by mass. Through this operation, the content of the antibacterial polyol is changed.

2. Evaluation test methods

Each test sample was evaluated by the same test method as the evaluation test of the makeup removers of Examples 1 to 18 and Comparative Examples 1 to 13.

In addition, the evaluation test items are based on "<Appearance observation (transparency)>, (a) Appearance immediately after preparation, (b) Appearance after stability test (stability)", "<Rinseability (volume of emulsified particles)" Measurement of standard average particle size)>" is carried out.

3. Evaluation results

The evaluation results are shown in the lower part of Table 4 below.

[Table 4]

<Appearance observation (transparency)>

(a) Appearance immediately after preparation

Only the makeup remover having the composition of Comparative Example 19 is a transparent makeup remover. On the other hand, the appearance of the makeup removers of the compositions of Comparative Examples 16 to 18 and Comparative Examples 20 to 31 immediately after preparation was cloudy and opaque. Therefore, the samples other than Comparative Example 19 were judged to be unsatisfactory, and only the sample of Comparative Example 19, which maintained a transparent appearance, was subjected to a stability test of storage in a constant temperature room of 5°C, 25°C, 40°C, and 50°C.

(b) Appearance after stability test (stability)

The makeup remover of Comparative Example 19 subjected to the stability test was stored in a constant temperature room at 5°C, 25°C, 40°C, and 50°C for 1 month and then taken out to evaluate the transparency. The transparency was maintained at temperatures of 5°C and 25°C, but separation occurred at temperatures of 40°C and 50°C. Therefore, Comparative Example 19 failed to achieve the intended stability and was judged to be unsatisfactory.

<Rinsing performance (measurement of volume standard average particle size of emulsified particles)>

Only the makeup remover of Comparative Example 19 that was transparent immediately after preparation was measured. The volume standard average particle size of the emulsified particle size of the diluent is shown in Table 4, and is 51.2 nm.

As described above, makeup removers having the compositions of Comparative Examples 16 to 31 were prepared, and a test was conducted to confirm the limit of the maximum content of the antibacterial polyol as component (F). However, it is difficult to contain 10% by mass or more of an antibacterial polyol as component (F). That is, it was judged that in order to prepare a transparent makeup remover with high storage stability for the purpose of the present invention, it is more preferable to contain 10 mass % or more of the antibacterial polyol as the component (F).
