Description

Anhydrous Eyebrow Make-up Cosmetic Composition

It relates to an anhydrous makeup cosmetic composition comprising a silicone elastomer, an oil thickener, and a plate-like powder.

In the case of eye-makeup, it can be divided into mascara, eyeliner, shadow, eyebrow, and the like. In particular, in the case of eyebrow makeup, it is recognized as a very important factor in determining a person's first impression, and various eyebrow makeup products are being released. In general, the effects that the eyebrow makeup cosmetic composition should have include color development, uniform application, and long-lasting durability without being easily spread by sweat and oil.

The eyebrow makeup cosmetic composition is classified into a pencil type, a powder type, a cream type, etc. according to the formulation. Among them, the pencil type is characterized by ease of use and waterproof function, but due to the nature of the formulation, it lacks lasting power due to smearing due to oil, and it has disadvantages in that it cannot cover the eyebrow hair. In addition, while the powder type has a natural makeup effect, it has a problem of durability such as dusting and cannot cover the eyebrow hairs like the pencil type. The cream type is largely divided into an oil-in-water type, an emulsion type, and an anhydrous type, and it can be applied to the mascara brush applicator to cover the eyebrow skin and hair. In the case of the underwater type, the color development is high, but there is a disadvantage that it does not have a waterproof effect. The emulsified type has a creamy texture and good spreadability and finish, but has a disadvantage of low color development due to the nature of the emulsified formulation. In the case of anhydrous type, it has high color development and strong waterproof effect, but there is a risk of oil separation, and the first touch is oily and the finish is stiff, so makeup is unnaturally expressed.

Accordingly, the present inventors have combined silicone elastomer, oil thickener, and plate-like powder in a certain ratio to develop an anhydrous makeup cosmetic composition having excellent formulation stability and a smooth finish without oily, and excellent adhesion. It was confirmed that it has excellent stability, is not oily on the first touch, dries quickly and adheres to the skin, and exhibits a soft finish makeup effect.

One aspect provides an anhydrous makeup cosmetic composition comprising a silicone elastomer, an oil thickener, and a plate-like powder.

One aspect provides an anhydrous makeup cosmetic composition comprising a silicone elastomer, an oil thickener, and a plate-like powder.

The silicone elastomer is present in an amount of 1 to 20% by weight, such as 1 to 19% by weight, such as 1 to 18% by weight, such as 1 to 15% by weight, such as 1 to 12% by weight. may include. When out of the above range, if the content of the silicone elastomer is low, the drying rate may be slow and adhesion may be deteriorated, and if the content of the silicone elastomer is high, the stability of the formulation may be deteriorated or the spreadability may be poor. Therefore, when the cosmetic composition contains the silicone elastomer in an amount within the above range, the adhesion and feeling of use of the formulation may be improved.

The silicone elastomer is dimethicone, dimethicone/dimethicone crosspolymer, dimethicone/vinyldimethicone crosspolymer, polysilicone-11, polymethylsilsesquioxane, dimethicone crosspolymer, dimethicone/PEG-10/15 Cross polymer, vinyl dimethicone/methicone silsesquioxane cross polymer, lauryl dimethicone cross polymer, dimethicone/polyglycerin-3 cross polymer, vinyl dimethicone/lauryl dimethicone cross polymer, diphenyl dimethicone/vinyl di It may be at least one selected from the group consisting of phenyldimethicone/silsesquioxane crosspolymer, and combinations thereof.

The silicone elastomer may be of a liquid type. In one embodiment, as compared to a cosmetic composition containing a powder type silicone elastomer, a cosmetic composition containing a liquid blend type silicone elastomer has an appropriate drying rate, and exhibits superior formulation stability, finish, spreadability and spreadability was confirmed.

The oil thickener is 1.5 to 15.5% by weight, such as 1.5 to 15% by weight, such as 2 to 15% by weight, such as 2 to 14.5% by weight, such as 2 to 14% by weight. , For example, 2.5 to 13.5% by weight, for example, 2.5 to 13.5% by weight, for example, it may be one comprising 3 to 12% by weight. When out of the above range, if the content of the oil thickener is low, stability and film feeling may be deteriorated, and the durability may be lowered, and if the content of the oil thickener is high, the spreadability of the formulation may be poor. Therefore, when the cosmetic composition contains the oil thickener in an amount within the above range, the stability of the formulation and the film feeling can be improved.

The oil thickener refers to a substance that increases viscosity. The oil thickener may include any substance used for the purpose of increasing the viscosity. Specifically, the oil thickener is dextrin palminate, dextrin palmitate / ethyl hexanoate, disteadimonium hectorite, ethylene / propylene copolymer, silica dimethyl silylate, silica silylate, glyceryl behenate / It may be at least one selected from eicosadioate, hydrogenated ethylene/propylene/styrene copolymer, and hydrogenated butylene/ethylene/styrene copolymer, and combinations thereof. In one embodiment, the oil thickener may be dextrin palminate, dextrin palmitate/ethylhexanoate, disteadimonium hectorite, or ethylene/propylene copolymer.

The plate-like powder is present in an amount of 13 to 44% by weight, for example, 13 to 34% by weight, for example, 15 to 34% by weight, for example, 15 to 27% by weight, for example, 13 to 27% by weight. may include. When out of the above range, if the content of the plate-like powder is high, aging may occur or the feeling of use may be rough, and the spreadability may be inhibited. Therefore, when the cosmetic composition contains the plate-shaped powder in an amount within the above range, the stability of the formulation, the finishing feeling such as matteness and creaminess, and the drying speed can be improved.

The powder means a collection of fine solid particles, and the plate-shaped powder means that the powder has a plate shape. Specifically, the plate-like powder is mica, talc, boron nitride, sericite, synthetic fluorophlogopite, barium sulfate, alumina ( Alumina), kaolin (kaolin), and may be at least one selected from the group consisting of combinations thereof. In one embodiment, the plate-like powder may be talc.

The cosmetic composition may be formulated in a form consisting of an oil-in-water (O/W) type, a water-in-oil (W/O) type, a water-in-silicone (W/Si) type, or an anhydrous type. Specifically, the cosmetic composition may be an anhydrous formulation. The anhydrous formulation comprises less than about 5%, less than about 4%, less than about 3%, less than about 2%, less than about 1%, or less than about 0.5% water by weight relative to the total weight of the composition. It may mean a composition. The anhydrous formulation may be used interchangeably with an anhydrous composition.

The cosmetic composition may be used for eye makeup. For example, the cosmetic composition may be a shadow, eyeliner, mascara, eyebrow mascara, eyebrow liner, etc., but is not limited thereto. Specifically, the makeup cosmetic composition may be used for eyebrow makeup.

The cosmetic composition can improve the stability and drying speed of the formulation by appropriately mixing the silicone elastomer, the oil thickener and the plate-shaped powder appropriately. In addition, the cosmetic composition may have improved feeling of use, such as color development, finish, spreadability, spreadability, or adhesion.

The cosmetic composition may further add components such as a dispersant, an antioxidant, a preservative, a pH adjuster, a humectant, and a lubricant, if necessary. In addition, the cosmetic 　 composition further includes a substance that can supplementally provide essential nutrients to the skin, preferably a natural fragrance, 　 cosmetic fragrance, or an auxiliary agent including but not limited to plant extracts. .

The cosmetic composition for anhydrous makeup containing silicone elastomer, oil thickener and plate-shaped powder is not oily and has a soft finish and adhesion, so it can overcome the limitations of the existing anhydrous makeup cosmetic composition, which has poor finish and formulation stability. have. In addition, it has excellent color development and durability, and may have a strong waterproof effect.
