Description

The present invention relates to an aqueous gel-like cosmetic that is useful as a skin cosmetic.

Aqueous cosmetics are cosmetics that contain almost no oily ingredients, and a fresh feel is preferred. Since the main component of water-based cosmetics is water, the presence of intercellular lipids and sebum in the stratum corneum makes it difficult for them to become lipophilic to the skin, and the feeling of penetration may be insufficient.
On the other hand, it has long been known that the permeation feeling is improved by adding ethanol or a surfactant, but ethanol may be irritating to the skin or is derived from a surfactant. Stickiness may occur.
To solve this problem, Patent Document 1 contains an alkyl-modified carboxyvinyl polymer, ascorbic acids, 1,3-propanediol, a water-soluble polysaccharide, and water, and a feeling of permeation can be quickly felt after application, resulting in stickiness and stickiness. Cosmetics with improved squeaky feeling have been proposed. Patent Document 2 describes phospholipid derivatives such as collagen, hydrogenated soybean phospholipids, hydroxylated soybean phospholipids, 2-methacryloyloxyethylphosphorylcholine / butylmethacrylate copolymers and / or phospholipid polymers, polyoxyethylene methyl. Proposed skin cosmetics containing glucosides and polyhydric alcohols, having an excellent moisturizing effect and reducing the sticky feeling after application.

In addition, in order to further enhance the functionality, there is a need for a function that gives the skin a fluffy feel (a feel that the deeper part of the skin (the back of the skin) feels soft) while taking advantage of the features of water-based cosmetics. ..
To solve this problem, Patent Document 3 contains a water-affinitive compound having a dimethylsilane skeleton and a polymer obtained by radical polymerization of dimethylacrylamide and 2-acrylamide-2-methylpropanesulfonic acid, and skin. Aqueous skin cosmetics have been proposed, which have excellent elongation, familiarity, non-greasiness, freshness, penetration, emollient feeling, and elasticity. Patent Document 4 describes one or more acrylic acid-based polymers selected from acrylic acid / alkyl methacrylate copolymer, crosslinked polyacrylic acid, and polyacrylic acid, hydrogenated soybean phospholipids, and 2-methacryloyloxyethyl phosphorylcholine. Contains one or more phospholipid polymers selected from butyl methacrylate copolymers, trimethylglycine, and dimethylsilanol-hyaluronic acid condensate, which has good spreadability, non-stickiness, high moisturizing properties, and firmness on the skin. Cosmetics to give have been proposed.

On the other hand, in recent years, attempts have been made to give a high-class feeling to a pharmaceutical product in addition to a feeling of use. For example, a water-based gel-like cosmetic containing a water-soluble polymer to give viscosity is high-grade because it has a thick appearance and an appropriate resistance when applied (hereinafter, also referred to as "richness"). You can produce a feeling. However, in order to impart these functions, a large amount of water-soluble polymer may be blended, and in that case, a lack of smooth feel (hereinafter, also referred to as “stickiness”) occurs immediately after application. There was a case.
To solve this problem, Patent Document 5 describes a technique for blending a water-soluble polysaccharide and a specific acrylic polymer compound into a gel-like skin cosmetic having a high viscosity and no unpleasant feeling of use. Proposed. Immediately after applying such cosmetics, moisturizing ingredients contained in the cosmetics remain on the skin, so it is difficult to feel a feeling of being caught, and several hours to a day after application, sebum is secreted, resulting in a feeling of being caught. It is suppressed. That is, the water-based gel-like cosmetics which are hard to feel caught are disclosed immediately after the application of the water-based cosmetics and when several hours to one day have passed after the application.

However, the present inventors feel that the moisturizing component and the oily component are absorbed by the skin or volatilize during the period from 30 minutes to several hours after the application of the water-based cosmetics, resulting in a feeling of being caught. We have found that a new issue arises, that is, it will occur.

Japanese Unexamined Patent Publication No. 2016-204343 Japanese Unexamined Patent Publication No. 2010-12859 Japanese Unexamined Patent Publication No. 2013-12678 Japanese Unexamined Patent Publication No. 2016-09824 Japanese Unexamined Patent Publication No. 2013-107862

Therefore, the present invention has excellent richness and permeation feeling at the time of application, is less sticky, and is less likely to feel stuck even after a while after application, that is, within a period of about 30 minutes to several hours after application, and lasts. The purpose of the present invention is to provide a water-based gel-like cosmetic that can give a fluffy feel to the skin.

As a result of diligent studies to solve the above problems, the present inventors have obtained (A) 2-methacryloyloxyethyl phosphorylcholine / butyl methacrylate copolymer and (B) 2-methacryloyloxyethylphosphorylcholine / stearyl methacrylate copolymer. Contains one or more selected from the group consisting of coalesced, (C) phospholipids, (D) polyethylene glycols with an average molecular weight of 300-5,000, (E) carboxyvinyl polymers and alkyl-modified carboxyvinyl polymers.
