Description

The present invention relates to a gel-like cosmetic that gives a warm feeling.

Skin care such as packs and massages normalizes stagnant blood flow, promotes metabolism of the entire skin, activates cell functions to increase the production of important components, and repairs damaged areas. It is a beauty method that gives vitality to the skin by enhancing it, and realizes lively skin, plump, moisturized and supple skin.
Generally, when performing skin care such as facial masks and massages, there is an action process of applying the cosmetics for it to the skin of the face and limbs, and in some cases, the process of keeping the applied cosmetics on the skin for a certain period of time. Is provided. In order to carry out these processes smoothly and to obtain a good feeling of use and beauty effect, the skin care cosmetics used for facial masks and massages use dosage forms such as gels, creams, and foams. Gel-like cosmetics are preferred for their good feel and beautiful appearance.

In addition, various cosmetics that give a feeling of warmth to the skin in anticipation of a blood circulation promoting effect and the like have been proposed. As a warming component to be blended in such cosmetics, plant extracts such as pepper and ginger, vanillyl alkyl ether, and the like are known (Patent Document 1). In addition, polyhydric alcohols such as glycerin and polyethylene glycol also generate high heat of hydration, and are known as warming agents to be blended in cosmetics (Patent Documents 2 and 3). In particular, glycerin and polyethylene glycol are used. It is disclosed that a good warmth can be obtained by combining them into a gel-like cosmetic (Patent Document 4).

In general, the gel dosage form may be inferior in ductility at the time of application as compared with the cream dosage form. The gel-like cosmetics described in Patent Document 4 also give a good feeling of warmth by the combination of glycerin and polyethylene glycol, but have a problem that they are not slippery at the time of application and are difficult to spread on the skin.
In view of such a situation, it is an object of the present invention to provide a gel-like cosmetic which gives a warm feeling, has excellent spreadability at the time of application, and has a good usability.

As a result of diligent research, the present inventors have found that the combination of glycerin and polyoxyalkylene polyhydric alcohol ether improves the slipperiness when applying gel cosmetics, and further combines glycerin and polyethylene glycol. We have also found that a feeling of warmth equal to or higher than that of the case can be obtained, and have completed the present invention.

That is, the present invention is as follows.
[1] A gel-like cosmetic containing a) glycerin, b) a polyoxyalkylene polyhydric alcohol ether, and c) a thickener.
[2] a) The gel-like cosmetic according to [1], wherein the content of glycerin is 50 to 95% by mass with respect to the total amount of the cosmetic.
[3] b) The gel-like cosmetic according to [1] or [2], wherein the content of the polyoxyalkylene polyhydric alcohol ether is 3 to 20% by mass with respect to the total amount of the cosmetic.
[4] b) The gel-like cosmetic according to any one of [1] to [3], wherein the polyoxyalkylene polyhydric alcohol ether is a polyoxyethylene glyceryl ether.
[5] c) The gel-like cosmetic according to any one of [1] to [4], wherein the thickener is an alkyl-modified carboxyvinyl polymer and / or a salt thereof.
[6] The gel-like cosmetic according to any one of [1] to [5], which does not substantially contain a surfactant.
[7] The gel-like cosmetic according to any one of [1] to [6], wherein the water content is 0 to 15% by mass.

The cosmetic of the present invention gives a warm feeling just by applying it to the skin, and it is slippery at the time of application and can be easily spread on the skin. Therefore, according to the present invention, a gel-like cosmetic having a good usability is provided.
