Description

TECHNICAL FIELD [0001] The present invention relates to a cosmetic composition having excellent moisturizing properties and a method for preparing the same,

The present invention relates to a color cosmetic composition, and more specifically, to a color cosmetic composition which is soft and smooth and has improved spreading properties, and is capable of smooth skin cosmetic expression and excellent moisturization, and a method for producing the same.

Typical makeup cosmetics include a liquid foundation or a solid foundation, and a compact, two-way cake, pressed powder, or compressed fact, which is made up of a powder as a main component. The purpose of each of the above-described products is to mask stain or dirt, and is used to give skin coverage and bright skin expression. The makeup cosmetics have spreadability, adhesion, and moist feeling, but may cause lift-up phenomenon due to particle aggregation.

Looking at recent make-up trends, makeup cosmetics are being demanded not only for their mood properties such as coverage, adhesion, and spreadability, but also their moisturizing properties. In addition, consumers who use makeup cosmetics also regard moisture as very important, which has become a key buying factor in product selection criteria. Accordingly, various studies have been carried out to improve the moisturization of makeup cosmetics. However, there is a problem in that when the moisturizing effect is improved in a conventional color cosmetic composition, particularly a liquid foundation or a solid foundation cosmetic composition, the adhesion is deteriorated. In addition, although the moisturization can be improved by changing the ratio of oil and water, it is possible to increase the skin roughness and make up the skin smoothly, and oil or grain aggregation may occur in the local area. Further, when an oil having a low viscosity and an oil having a phenyl group bonded at a terminal or branch type are used, the luster and moisturization are improved, but the adhesion and the sustainability are deteriorated.

Also, a method of blending a high amount of ester oil in the form of an oil binder in order to improve the moisturizing effect of a cosmetic composition such as a powder foundation or a compact, which is a main component of the powder, a method of reforming the powder surface with a natural-derived wax or synthetic wax, Emulsions, emulsions, emulsions containing water-in-oil type emulsifying binders including starch or modified starches, etc. However, these methods have limitations.

That is, when a high content of ester oil is blended with an oil binder which is a binder used for compression molding, the moisture content is improved but there is a limit in the blending amount. When the powder surface is coated or modified with a natural-derived wax or a synthetic wax, it is difficult to sufficiently exhibit the effect in a small amount. When a large amount of the coating is applied, the surface of the wax or synthetic wax A phenomenon in which the product is not picked up when picking up the product with a puff or a brush may occur. Further, greasing phenomenon or caking phenomenon caused by aggregation of oil or wax may occur. In addition, a cosmetic composition containing an emulsion of starch or modified starch and containing a polyol and an emulsion is subjected to a sintering process in order to evaporate moisture in the formulation and improve stability. In order to impart moistness, And the moisture may not be exerted. In addition, although the makeup cosmetic material of the plastic type is attempted to be formulated using an aqueous dispersion binder, a water-in-oil type or an underwater type emulsion binder, there is a limit to impart moisture. In addition, the firing type cosmetics have a disadvantage in that the surface has hardness and cracking phenomenon, the drop stability is low, and the ability to express color is insufficient.

In the make-up cosmetics, moist feeling and adhesion are indispensable factors, but powder formulations are particularly limited in their ability to impart a moist feeling due to their formulation properties. In addition, powder formulations may cause caking phenomenon or grazing phenomenon, and may cause cosmetic clumping phenomenon or clumping of makeup due to particle clumping during application of the product. As described above, various methods have been tried to improve the moist feel of the cosmetics, but the effectiveness is still insufficient and the effect that the consumer feels has not been exerted.

Accordingly, there is a need to develop a color cosmetic composition having excellent moisturizing feel and adhesion while exhibiting smooth skin cosmetic expression without causing clumping of makeup.

A problem to be solved by the present invention is to provide a color cosmetic composition which is improved in moist feeling and adhesion at the same time, and has a smooth skin expression and little lift-up phenomenon.

The present invention provides a tinted cosmetic composition comprising a wet-coated sericite, a synthetic mica, and a spherical powder. In addition, the composition may additionally comprise a talc coated with a fatty acid, an emulsifier, or a mixture thereof. In addition, the color cosmetic composition may be preferably a light-colored cosmetic composition.

As a result, the inventors of the present invention selected sericite to provide a feeling of soft feeling in order to improve the feeling of moist feeling, and various attempts were made to modify the surface of the sericite having a specific particle size and distribution. In addition, spherical powders having excellent dispersibility and having a wide range of particle size distribution and having a sharp shape were used together for smooth spreadability. In addition, for the purpose of adhesion, a talc processed by a specific material was selected as a material. The color cosmetic composition prepared as described above has remarkable discoveries that it is excellent in wetting and moisturizing, has excellent skin adhesion, and exhibits a smooth cosmetic effect, thereby completing the present invention.
