Description

[Technical Field]

[0001] The present invention relates to an aqueous cosmetic preparation. [Background technology]

[0002] Aqueous cosmetics are often used in skin care products due to their fresh texture and good spreadability. Furthermore, many plant extracts used as cosmetic ingredients are water-soluble, and therefore are used in aqueous cosmetics (e.g., serums, etc.). With the recent increase in interest in eyelash care, eyelash serums have been attracting attention in the market, and the development of eyelash serums that can produce noticeable hair growth effects is eagerly awaited.

[0003] Technologies relating to eyelash serums and hair growth compositions have been developed to date. For example, a cosmetic product for the eyelashes and eyelash roots has been disclosed that contains a hair growth agent, a thickener, and a film-forming agent with a specific refractive index to promote eyelash growth and achieve long, beautiful eyelashes, and can be applied without stickiness, and has makeup effects such as giving the eyelashes a glossy finish and making them appear thicker (see, for example, Patent Document 1).

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-306854 Summary of the Invention [Problem to be solved by the invention]

[0005]

[0003] Conventional techniques have been excellent in eyelash growth and luster, but have not provided satisfactory qualities in terms of eyelash sting resistance and firmness when the applied aqueous cosmetic composition drips onto the eyes, or drying speed, which is particularly important when used before applying makeup. Furthermore, reducing the amount applied to the eyelashes in order to increase the drying speed has resulted in failure to provide satisfactory qualities in eyelash extension, eyelash sting resistance, and firmness. On the other hand, increasing the amount applied to the eyelashes has resulted in achievement of eyelash extension and eyelash sting resistance, but has sometimes resulted in failure to provide satisfactory qualities in terms of drying speed. Therefore, an object of the present invention is to provide an aqueous cosmetic composition that can be applied in an appropriate amount to the eyelashes and is excellent in eyelash extension, drying speed, eyelash sting resistance, and firmness. [Means for solving the problem]

[0006] As a result of extensive research, the present inventors have discovered that by containing an extract of a plant of the Myrothamnaceae family, a water-soluble polymer, and a lower alcohol, and by adjusting the viscosity at 25°C to 30,000 to 100,000 mPa·s, it is possible to obtain an aqueous cosmetic composition that can be applied in an appropriate amount from the base to the tip of the eyelashes, promotes eyelash growth, and is excellent in all respects: drying speed, resistance to smudging, and firmness, and has thereby completed the present invention.

[0007] That is, the present invention includes the following aspects. [1] The following components (A) to (C): (A) Extract of Myrothamnus family plants (B) Water-soluble polymer (C) Lower alcohol and having a viscosity of 30,000 to 100,000 mPa·s at 25°C. [2] The aqueous cosmetic preparation according to [1], wherein the component (B) comprises (B1) polyacrylic acid or a salt thereof. [3] The aqueous cosmetic preparation according to [1] or [2], which contains two or more water-soluble polymers as the component (B). [4] The aqueous cosmetic preparation according to [1] or [2], wherein the mass ratio (C) / (B) of the component (C) to the component (B) is 5 to 150. [5] The aqueous cosmetic preparation according to [1] or [2], wherein the content of the component (C) is 1 to 50% by mass. [6] The aqueous cosmetic preparation according to [1] or [2] further contains a component (D) (VP / VA) copolymer. [7] The aqueous cosmetic preparation according to [1] or [2], which is a hair cosmetic preparation. [8] [7] The aqueous cosmetic preparation according to [7], which is a beauty serum for eyelashes. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide an aqueous cosmetic composition that is excellent in all respects: an appropriate amount to be applied to eyelashes, eyelash extension property, drying speed, resistance to stinging, and firmness.

[0042] (Manufacturing method) A. Mix ingredients (1) to (11) uniformly at 25°C. B. A was filled into a container using a mascara filling machine to obtain an aqueous eyelash serum.

[0043] [Evaluation method 1] (Evaluation item: eyelash lengthening) A panel of 10 cosmetic product evaluators applied each sample to their eyelashes and lash line once morning and night for one month. Images of each panel's eyelashes were taken from the front before and after one month of use, and a 1cm square was cropped from the image near the center of the eye. The image was binarized so that the eyelashes appeared black and the rest of the eye was white, and the area of ​​the black area corresponding to the eyelashes was measured. The average eyelash areas of the 10 panelists before and after use of the water-based eyelash serum were compared, and Y / X was calculated, where X was the average eyelash area of ​​the 10 panelists before use and Y was the average eyelash area of ​​the 10 panelists after one month of use. [Judgment criteria] (Judgment): (Y / X value) ◎: 1.10 or higher ○: 1.06 or more and less than 1.10 △: 1.02 or more and less than 1.06 ×: Less than 1.02

[0044] [Evaluation method 2] (Evaluation item: drying speed) Immediately after preparation, 1 g of each sample was taken, and its weight (a) on the artificial leather was measured in advance. Immediately after application, the surface was smoothed with a 100 μm doctor blade to form a uniform 100 μm coating film. The weight (b) was measured, and the sample was then left at 25°C for 10 minutes. After 10 minutes, the weight (c) of the coated artificial leather was measured. The weight of the sample before the 10-minute stand [(b) - (c)] was multiplied by the proportion of liquid components contained in the sample before the 10-minute stand [M], and the weight of the sample after the 10-minute stand [(b) - (a)] was defined as N, and the proportion of volatilized liquid components was calculated. The amount of change expressed by the following formula (1) was taken as the proportion of volatilized liquid components. The degree of volatilization was evaluated according to the following criteria. The proportions were converted to percentages for evaluation. [Proportion of volatilized liquid components] Ratio of evaporated liquid component = 1-(N / M) (1) [Judgment criteria] (Judgment) :(Drying speed) ◎: 90% or more of the liquid components have evaporated 〇: Volatilized liquid component is 70% or more but less than 90% △: Volatilized liquid component is 50% or more but less than 70% ×: Less than 50% of the liquid component has evaporated

[0045] [Evaluation method 3] (Evaluation criteria: non-stinging, appropriate amount applied to eyelashes, firmness) For each sample, 20 members of a panel of cosmetic product experts individually rated each sample on a 5-point scale for the categories of "non-staining," "appropriate amount applied to eyelashes," and "firmness," according to the absolute evaluation criteria below, and then used the average of the scores of all panelists to judge the results according to the following criteria: "non-staining," "appropriate amount applied to eyelashes," and "firmness" were evaluated by each panelist immediately after applying each sample to the eyelashes and lash line.

[0046] (Absolute evaluation criteria for stain resistance) (Score) :(Evaluation) 4 points: Very good (no stinging at all) 3 points: Good (slight stinging) 2 points: Normal (a little stinging but no pain) 1 point: Poor (stings and feels a little pain) 0 points: Very bad (stings strongly and causes pain) (Absolute evaluation standard for the appropriate amount of application to eyelashes) (Score) :(Evaluation) 4 points: Very good (just the right amount of application) 3 points: Good (slightly more or less) 2 points: Normal (too much or too little, but still acceptable) 1 point: Poor (too much or too little) 0 points: Very poor (very much or very little) (Absolute evaluation standard for firmness) (Score) :(Evaluation) 4 points: Very good (very firm) 3 points: Good (strong firmness) 2 points: Normal (firm) 1 point: Poor (weak firmness) 0 points: Very poor (no firmness at all)

[0047] (Judgment criteria) (Judgment): (Average score) ◎: 3.5 or above ○: 2.5 or more and less than 3.5 △: 1.5 or more and less than 2.5 ×: Less than 1.5

[0048] As is clear from the results in Tables 1 and 2, the aqueous eyelash serums of the Examples were excellent in all categories: "eyelash lengthening," "non-staining," "drying speed," "appropriate application amount to eyelashes," and "firmness." On the other hand, Comparative Example 1, which contained jujube fruit extract instead of component (A), did not achieve satisfactory quality in terms of eyelash lengthening. Furthermore, Comparative Example 2, which had a viscosity of more than 100,000 mPa·s, did not achieve satisfactory quality in terms of drying speed, appropriate application amount to eyelashes, or firmness. Comparative Example 3, which had a viscosity of less than 30,000 mPa·s, did not achieve satisfactory quality in terms of non-staining, appropriate application amount to eyelashes, or firmness. Furthermore, Comparative Example 4, which contained 1,3-butylene glycol instead of component (C), did not achieve satisfactory quality in terms of drying speed or firmness.
