DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gel cosmetic, and more particularly, to a gel cosmetic having good spreadability when applied, low stickiness, and excellent storage stability.

[0002]

2. Description of the Related Art Conventionally, there are various forms of cosmetics such as liquid, gel, cream, and stick. Among them, gel cosmetics are widely used because they are easily taken out by hand and easily spread when applied. ing. In general, gel cosmetics contain a carboxyl group-containing thickening polymer typified by a carboxyvinyl polymer, neutralized with an alkaline substance such as potassium hydroxide, sodium hydroxide, or triethanolamine, and blended with cellulose derivatives or guar gum. It blends natural polymers such as derivatives and adjusts its viscosity.

[0003] In addition, cosmetics conventionally include oils and fats, waxes, hydrocarbon oils, fatty acids, higher alcohols, ester oils, silicone oils, ultraviolet absorbers, water-insoluble vitamins and derivatives, flavors, powders and the like. Incorporates water-insoluble substances such as the body to adjust various feelings (moist, dry feeling) and functions (sunscreen, fragrance). It is known and widely used to incorporate a water-soluble alcohol in order to adjust the moisture retention and drying properties of the cosmetic.

However, when a gel-type cosmetic containing a carboxyl group-containing thickening polymer is blended with a water-soluble alcohol at a high concentration, the viscosity is impaired when a pressure is applied during application, making it difficult to apply or having an external appearance with time. And the storage stability is impaired, for example, resulting in a change in viscosity and a decrease in viscosity. In addition, even when a water-insoluble substance is added, storage stability such as a change in appearance over time or a decrease in viscosity tends to be impaired. When a nonionic surfactant is blended, the storage stability is improved, but when a large amount of the nonionic surfactant is blended, it causes stickiness. In addition, gel cosmetics containing a natural polymer tended to feel sticky in general.

[0005]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a gel cosmetic which has good spreadability at the time of application, has less sticky feeling, and has excellent storage stability.

[0006]
