Description

  The present invention relates to an aqueous composition containing tripropylene glycol, 2-methacryloyloxyethyl phosphorylcholine as a constituent unit, a polyoxyalkylene alkyl glucoside and water-containing transparent appearance, and has a moisturizing effect. Further, the present invention relates to a composition characterized by having no stickiness and improving skin transparency.

  Conventionally, aqueous cosmetics have a sense of penetration, and the market has been established as an item with a fresh and refreshing feeling of use. High moisturizing effect and high moisture content of the stratum corneum by adding a large amount of water-soluble cellulose, water-soluble starch, and polyglycerin for the purpose of improving the moisturizing ability, which is the basic quality of skin care cosmetics, and excellent usability (for example, patents) References 1 and 2) Reduction of stickiness, luster, and squeaky feeling due to the use of tripropylene glycol (for example, Patent Document 3), and production of a non-sticky feel by using organic particulate materials such as organosilicone polymers and polyethylene ( For example, a technique such as Patent Document 4) has been known.

However, Patent Documents 1 and 2 do not eliminate unpleasant stickiness due to water-soluble components. Patent Document 3 combines tripropylene glycol that has been tried to eliminate stickiness with a humectant, and Patent Document that contains organic particulate matter. In No. 4, it was not excellent in the persistence of moisture retention and the improvement of skin transparency due to the increase in the stratum corneum moisture content.

In view of such circumstances, the present inventors have conducted extensive studies, and as a result of various studies on water-soluble moisturizing ingredients that impart a moisturizing effect to the skin, polyoxyalkylene alkyl glucosides having a polyoxyalkylene group and having a glucoside structure are obtained. In particular, it was considered excellent from the viewpoint of moisture retention. And in order to increase the moisturizing effect of this component, while examining the aqueous medium, we obtained the knowledge that the moisturizing effect is also affected by the combination with the polyhydric alcohol. It has been found that the moisturizing effect is particularly enhanced by combining with tripropylene glycol. This is thought to be because tripropylene glycol has a feel close to that of a low-molecular oil component and further promotes penetration of the water-soluble moisturizing component due to the stratum corneum softening effect. In addition, as a component for sustaining this moisturizing effect, in the course of studying the third component, a polymer having 2-methacryloyloxyethylphosphorylcholine as a constituent unit significantly improves the moisturizing effect. As a result, it was found that the amount of water in the stratum corneum was increased and the transparency of the skin was improved, and the present invention was completed.
That is, the present invention includes the following components (A) to (D);
(A) Tripropylene glycol (B) One or more selected from a homopolymer of 2-methacryloyloxyethyl phosphorylcholine and a copolymer of 2-methacryloyloxyethyl phosphorylcholine and a hydrophobic monomer (C) Polyoxyalkylene alkyl It is a composition containing glucoside (D) water.
