Description

SKIN COSMETICS, BODY WASHING COMPOSITION AND OILY MAKE-UP COSMETICS}

The present invention relates to an external preparation for skin, and more particularly, to a skin cosmetic that provides a glossy feeling upon application and improves the adhesion to the skin and the retention of makeup of a water-based makeup cosmetic.

Further, the present invention relates to a body cleanser, and more particularly, a body cleanser that has a mild feeling of use even when applied to sensitive areas such as women's delicate zones, and has excellent foam retention during cleansing and provides a refreshing feeling of cleansing. It's about the composition.

Further, the present invention relates to an oil-based makeup cosmetic, and more particularly, to an oil-based makeup cosmetic that can be easily removed with an aqueous cleansing agent, has smooth diffusivity, and does not cause dryness over time.

Conventionally, makeup cosmetics are used for the purpose of creating beautiful skin and impressive eyes and lips with coloring and shadows. In order to maximize the cosmetic effect, it is important to form a uniform and beautiful cosmetic film on the skin. Water-based makeup cosmetics, such as dispersion-type water-based cosmetics in which powder is dispersed in water or water-based emulsified cosmetics containing powder, are popular among the younger generation as cosmetic formulations with a glossy and smooth feeling of use and less burden on the skin. is high

However, while water-based makeup cosmetics have an excellent glossy and smooth feeling of use, they are inferior in adhesion to the skin compared to oil-based makeup cosmetics or water-in-oil makeup cosmetics, and it is difficult to improve the adhesion of the makeup film or the makeup retention.

In view of these circumstances, water-based makeup cosmetics have been proposed for the purpose of improving adhesion to the skin, adhesion of a cosmetic film, and retention of makeup. For example, Patent Literature 1 proposes an aqueous makeup cosmetic characterized by blending glycosyltrehalose, polyacrylate, and powder.

The scalp, eyebrows, eyelashes, armpits, genital area, and the like are sites where oil glands are concentrated, and contamination by secretions such as sebum and protein is easily accumulated. These stains tend to cause various skin troubles due to the proliferation of bacteria in addition to discomfort such as stickiness. In particular, in women's sensitive zones, accumulation of sebum causes odor, furthermore, discomfort due to cold and menstrual blood, and furthermore, troubles such as rashes and eczema occur.

In general, in order to remove sebum and other contaminants from the body, body cleansers such as soap and body shampoo are used. However, general body cleansers have insufficient cleansing power against complex sebum and protein contamination, and a refreshing feeling of cleansing is not obtained. did not

Then, in patent document 2, the skin cleaning agent composition containing a cationic surfactant, a nonionic surfactant, a water-soluble inorganic salt, and alcohol in a specific ratio is proposed. Moreover, in patent document 3, the cleaning agent composition containing silicone oil and a lower alcohol as a cleaning/cleaning component is proposed.

In recent years, along with changes in lifestyle, simplicity and speed in makeup are required, and the share of water-based cleansing materials such as cleansing water and cleansing sheets that can be impregnated with cotton or the like to easily remove makeup is expanding.

On the other hand, regarding make-up cosmetics, solid or gel-type oil-based make-up cosmetics are preferred in the market because of ease of carrying and ease of use. Oil-based makeup cosmetics, since oil is the main component, have high water resistance and excellent durability of cosmetic effects, and by containing a large amount of powder, they can effectively produce smooth diffusivity unique to powder.

However, since oil-based makeup cosmetics contain a large amount of powder, they tend to easily cause dryness due to sebum loss. In addition, since oily makeup cosmetics are the main component, it is difficult to remove them with water-based cleansing agents, and in order to completely remove them from the skin, it is necessary to use oil-based cleansing agents with high detergency such as cleansing oil.

Then, in Patent Document 4, a composition for lipstick containing a specific alkylene oxide derivative to prevent drying over time and having improved moisturizing properties is proposed. Further, Patent Document 5 proposes a makeup cosmetic that can be easily removed even with an aqueous cleansing agent by combining a film-forming emulsion polymer having a specific structure and a water-soluble film-forming polymer.

Japanese Unexamined Patent Publication No. 2008-273943 Japanese Unexamined Patent Publication No. 2001-187726 Japanese Unexamined Patent Publication No. 5-58408 Japanese Unexamined Patent Publication No. 2004-168759 Japanese Unexamined Patent Publication No. 2015-196646

In the water-based makeup cosmetics described in Patent Literature 1, the makeup retentivity is improved to some extent, but the adhesion of the makeup film is insufficient. In addition, various proposals have been made, but it has been difficult to realize the adhesion to the skin, the adhesion of a cosmetic film, and the retention of makeup with an aqueous makeup cosmetic that surpasses that of an oil-based makeup cosmetic.

An object of the present invention is to provide a skin cosmetic that provides a glossy feeling when applied and improves the adhesion to the skin and the makeup retention of the aqueous makeup cosmetic.

The cleaning agent of Patent Literature 2 is excellent in refreshing feeling after washing, but contains a cationic surfactant, so it could not be said to be sufficiently mild for washing women's sensitive zones.

In addition, in the cleaning agent composition of Patent Document 3, a certain refreshing feeling and mildness were obtained, but the durability of the foam during washing of the delicate zone was insufficient.

In this way, a body cleanser that simultaneously satisfies the mildness of the delicate zone, the durability of foam during washing, and the refreshing feeling of washing has not been obtained.

An object of the present invention is to provide a body wash composition that provides a mild feeling of use even when applied to sensitive areas such as women's delicate zones, excellent foam retention during washing, and a refreshing feeling of washing.

It was difficult to sufficiently remove the make-up cosmetics of Patent Document 4 with an aqueous cleansing agent.

In addition, since the composition for lipstick of Patent Document 5 cannot contain a high amount of oil and powder, it is insufficient in terms of smooth spreadability at the time of application.

In this way, an oil-based makeup cosmetic that simultaneously satisfies that it can be washed easily with an aqueous cleansing agent, has smooth diffusivity during application, and does not feel dry over time has not been obtained.

An object of the present invention is to provide an oil-based makeup cosmetic that can be easily removed with an aqueous cleansing agent, has smooth diffusivity, and does not cause dryness over time.

In order to solve the above problems, the present inventors paid attention not to the water-based makeup cosmetics themselves, but to the makeup foundation, and to make the makeup foundation act as a binder, so that the adhesion to the skin and the makeup retention of the water-based makeup cosmetics can be improved. I thought it wasn't. As a result of intensive examination by the present inventors, it was found that a skin cosmetic composition in which two types of alkylene oxide derivatives, a water-soluble thickener, and water were combined in a specific ratio solved all of the above problems, and completed the present invention.

That is, the 1st invention contains 0.1-25 mass % of the following component (a), 0.01-5 mass % of component (b), and 0.01-5 mass % of component (c), and component (b) It relates to a skin cosmetic characterized in that the mass ratio ((b)/(a)) to component (a) is 1/200 to 1/6.

[Component (a)]

In the polyalkylene oxide derivative represented by the general formula (1) in the present invention, Z is a residue obtained by removing a hydroxyl group from an alcohol having 1 to 6 carbon atoms (Z(OH)p), p represents the valency of the alcohol, and 1 is ~ 6.

When the carbon number of the alcohol (Z(OH)p) exceeds 6, gloss at the time of application is impaired, so it is set to 6 or less, but 3 or less is more preferable. In addition, when the number of carbon atoms of the alcohol (Z(OH)p) is zero, that is, when it is a hydrogen atom, the adhesiveness of aqueous makeup and the retention of makeup decrease, so it is set to 1 or more. In addition, when the valence p of the alcohol (Z(OH)p) exceeds 6, the adhesion of aqueous makeup and the retention of makeup decrease, so it is 6 or less, but it is more preferably 3 or less.

The alcohol (Z(OH)p) is, specifically, methanol, ethanol, n-propanol, isopropanol, n-butanol, sec-butanol, tert-butanol, pentanol, hexanol, ethylene glycol, propylene glycol, butyl Examples include alcohols such as len glycol, pentylene glycol, hexylene glycol, glycerin, erythritol, pentaerythritol, xylitol, trimethylolpropane, and sorbitol.

The average added mole number “p×m” of A ¹ O as a whole in component (a) is 1 to 70, preferably 3 to 50, more preferably 5 to 40. When "p x m" exceeds 70, the gloss at the time of application is impaired, and when it is less than 1, the adhesiveness of aqueous makeup and makeup retention properties deteriorate.

n is the average added mole number of EO per 1 hydroxyl group of the alcohol. The number of moles of EO added in the component (a) as a whole is from 1 to 70, preferably from 5 to 60, and more preferably from 10 to 50. When "p x n" exceeds 70, the adhesion of water-based makeup and make-up retention properties decrease, and when it is less than 1, gloss at the time of application is impaired.

The ratio "n/(m + n)" of the average number of added moles of the oxyethylene group EO to the sum of the average number of added moles of the oxyalkylene group A ¹ O and the average number of added moles of the oxyethylene group EO is 0.15 to 0.75 , preferably from 0.30 to 0.72, more preferably from 0.45 to 0.70. When this ratio exceeds 0.75, the adhesion and makeup retention properties of aqueous makeup deteriorate, and when it is less than 0.15, gloss at the time of application is impaired.

1: Residual foundation was clearly confirmed

0: Almost could not remove foundation

<Examples 1 to 6 and Comparative Examples 1 to 10>

A body cleanser was prepared and evaluated by the method described above. Table 9, Table 10 and Table 11 show prescriptions and results. In addition, in all formulations, it was prepared on a 100 g scale. In addition, since separation was confirmed immediately after preparation, or problems such as non-solidification or non-aggregation of preparations were confirmed for those described as "-" in the evaluation column of Table 11, evaluation was not performed.

About Examples 1-6, it could be easily removed with an aqueous cleansing agent, had smooth diffusivity, and was good also in the absence of dry feeling with the passage of time.

On the other hand, a sufficient effect was not obtained about Comparative Examples 1-10. In Comparative Examples 1 to 4, since component (a') outside the scope of the present invention was used instead of component (a), all properties were deteriorated.

In Comparative Examples 5 and 6, since component (b') outside the scope of the present invention was used instead of component (b), all properties were deteriorated.

In Comparative Example 7, since the component (b) was not contained, it was insufficient in the washability by the aqueous cleansing agent.

In Comparative Examples 8, 9, and 10, since the contents of component (a), component (g), and component (h) respectively exceeded the scope of the invention, stable formulations could not be obtained.
