Description

TECHNICAL FIELD The present invention relates to a composition for stabilizing cosmetic compositions using pentaerythritol and derivatives thereof,

The present invention relates to a cosmetic stabilizer composition containing a polyol compound having four hydroxy groups. The present invention also relates to a cosmetic composition containing a polyol compound having four hydroxy groups.

Recently, researches are being conducted to give new value to cosmetics using various cosmetic formulation techniques. In particular, emulsions are the most commonly used formulations in the cosmetics industry, in which the oil phase and water phase are evenly dispersed using emulsification technology, and the pickling emulsion means an emulsion stabilized by solid particles. Compared to emulsions using emulsifiers, the Pickering emulsion does not use emulsifiers. Therefore, it has excellent safety and has strong thixotropy, which gives a new feeling of use such as good dripping. Therefore, not only in the field of cosmetics but also in the field of medicine, And most of them are developed and applied as an underwater type emulsion which is easy to stabilize. Korean Patent Laid-Open No. 10-2009-0028309 (a method of stabilizing a cosmetic composition containing an oil and a polyol and a cosmetic composition using the same) is an underwater type in which moisture is exposed to the outside, and the polyol component is used as an oxidation stabilizer However, the stability of the water-in-oil type curling emulsion has not been disclosed at all. The water-in-oil type pickling emulsion has the advantages of excellent water resistance and durability, but it has a problem that the long-term stability is not good. Therefore, the water-in-oil type pickling emulsion has a problem of poor water resistance and durability. Many studies have been conducted to improve the stability of Pickering emulsion.

The inventors of the present invention have conducted studies on powder essence with excellent stability against temperature change and microvibration, and as a result, they have found that the stability depends on the number and position of the hydroxyl groups of the polyol. The present invention has been completed through experiments.

Accordingly, an object of the present invention is to provide a cosmetic stabilizer composition.

It is another object of the present invention to provide a cosmetic composition containing the stabilizer composition.

Other objects and advantages of the present invention will become more apparent from the following description of the invention and from the claims.

According to one aspect of the present invention, there is provided a cosmetic stabilizer composition containing a polyol compound having at least four hydroxy groups. The polyol compound means a polyhydric alcohol, that is, an aliphatic compound having two or more hydroxyl groups, typically glycerol having three hydroxyl groups and pentaerythritol having four hydroxyl groups.

When the content is less than 5%, there is a problem of weakness of the moisturizing effect. When the content is 40% or more, it is not preferable in view of sticky feeling and occlusion phenomenon.

The cosmetic composition of the present invention is characterized in that the composition of the present invention is at least one selected from the group consisting of softening agents, convergent lotion, nutritional lotion, nutritional cream, massage cream, eye cream, eye essence, essence, cleansing cream, cleansing lotion, cleansing foam, cleansing water, , A body cream, a body essence, a body cleanser, a hair dye, a shampoo, a rinse, a toothpaste, an oral cleanser, a regularizer, a hair preparation, a lotion, an ointment, a gel, a cream, a patch or a spray. It is advantageous in terms of feeling of use.

The present invention relates to a cosmetic stabilizer composition containing a polyol compound having at least four hydroxy groups, and the following effects can be obtained by using the present invention.

(a) It is possible to prepare a pickling emulsion powder composition which overcomes the disadvantages of existing conventional polyols and is less affected by temperature and external microvibration in the pickling emulsion system, and which is cool, free from dusting, and excellent in moisturizing properties.

(b) In addition, separation phenomenon can be avoided, thereby providing convenience of distribution of the cosmetic composition.
