Description

  The present invention relates to an aqueous cosmetic useful as a skin cosmetic.

The aqueous cosmetic composition is a cosmetic composition which is mainly composed of water and a water-soluble component and contains almost no oily component, and its fresh feeling is preferred. In recent years, an aqueous cosmetic having a viscosity imparted by a water-soluble polymer is particularly preferred because it provides a sense of high quality and has the convenience of being able to apply an appropriate amount without dropping when used.
However, since the aqueous cosmetic composition hardly contains an oily component, it tends to cause water evaporation on the application surface of the skin, and even if it is given a moisturizing feeling immediately after the application, it does not reach to give a sustained moisturizing feeling. was there.

  Several inventions have been proposed to solve such problems. For example, Patent Document 1 discloses an aqueous cosmetic containing lysophospholipid, mucopolysaccharide, and a specific polyhydric alcohol containing at least a trihydric alcohol and a tetrahydric or higher alcohol as an aqueous cosmetic excellent in the moisturizing sustaining effect. Has been proposed. Further, in Patent Document 2, one or two or more types selected from mannosyl erythritol lipid, polyoxyethylene hydrogenated castor oil and polyoxyethylene fatty acid sorbitan as an aqueous cosmetic having an improved moisturizing effect, and having a number average molecular weight of 200 are obtained. An aqueous cosmetic composition containing at least 200,000 polyalkylene glycols and water is proposed. However, the aqueous cosmetic composition described in the above-mentioned patent documents is insufficient in the effect of giving the skin a plump feel.

A moisturizing feeling is a feeling that moisture can be felt on the skin surface, and a plump feeling is a feeling that a portion deeper than the skin surface (the back of the skin) can be felt soft. In order to give the skin a plump feel, it is common to blend an oil component. However, in order to exert the effect sufficiently, it is necessary to blend a large amount of the oil component. In order to stably incorporate the oil component into the aqueous cosmetic composition, it is necessary to add a surfactant, and as a result, the fresh feeling at the time of use, which is a feature of the aqueous cosmetic composition, is reduced and further it becomes sticky. There was a problem to occur.
With respect to the above problems, Patent Document 3 describes one or more acrylic acid-based polymers selected from acrylic acid / alkyl methacrylate copolymers, crosslinked polyacrylic acids, and polyacrylic acids, hydrogenated soybean phospholipids, 2- A skin cosmetic comprising one or more kinds of phospholipid polymers selected from methacryloyloxyethyl phosphorylcholine / butyl methacrylate copolymer, trimethylglycine, dimethylsilanol / hyaluronic acid condensation liquid has been proposed. The skin cosmetic described in Patent Document 3 can suppress the stickiness of the skin when applied to the skin, and can give the skin a firm and moist feeling.
However, with the skin cosmetic described in Patent Document 3, although it is possible to temporarily give a firm tension to the skin by enhancing the moisturizing effect, it has not yet reached a point of continuously giving a plump feeling. Furthermore, the effect (hereinafter referred to as "penetration") giving the feeling of penetration into the skin was also insufficient.
