Gel composition for skin

Abstract

The present invention provides a gel composition for skin that can easily gel even in an environment in which an electrolyte and ethanol are present, that exhibits an excellent effect in terms of the stability of the gel formulation thereof, and that exhibits excellent ease of use. The gel composition for skin is characterized by comprising an electrolyte (A), ethanol (B), a pectin (C) having a degree of methyl esterification (%) that is less than 50%, and a hydroxypropylated galactomannan polysaccharide thickener (D), preferably hydroxypropyl guar gum.

Description

technical field [0001] The present invention relates to a gel-like composition for skin. Background technique [0002] In order to impart a refreshing feeling of use to cosmetics applied to the skin, ethanol is generally used. In addition, from the viewpoint of usability at the time of application, the dosage form of cosmetics is often in the form of a gel. Such ethanol-containing gel compositions for skin generally use thickeners such as carboxyvinyl polymers or acrylic acid / alkyl methacrylate copolymers for thickening (see, for example, Patent Documents 1 and 2). [0003] However, when such a composition contains electrolytes, especially polyvalent cations, thickeners such as carboxyvinyl polymers or acrylic acid-alkyl methacrylate copolymers tend to cause aggregation, and the original sufficient cation cannot be obtained. Thickening effect, there is a problem that it cannot be gelled. [0004] On the other hand, in order to thicken compositions compounded with electrol...

Problems solved by technology

[0005] However, although thickening can be achieved to some extent through these attempts, the thickening effect of the nonionic polysaccharide thickener itself is very weak, and in order to make it gel, a high degree of mixing is required, so there are problems with stickiness and stickiness. Issues such as adverse effects caused by usability

In addition, when ethanol is contained in such a composition, the thickening effect of the nonionic polysaccharide thickener is significantly reduced, and there is also a problem that gelation cannot be achieved.

[0006] In attempts to use existing general-purpose raw materials with thickening effects, it is very difficult to make a composition containing both electrolytes and ethanol easily due to poor salt resistance (electrolyte resistance) or alcohol resistance (ethanol resistance). Thickening, and gelling, presents many technical problems
