Description

  The present invention relates to a gel composition that has excellent usability, is excellent in warming effect, massage effect, and makeup removing effect, and is useful as a cleansing, pack, and massage cosmetic. More specifically, the present invention relates to a gel composition having good safety, good elongation on the skin, and a feeling of use that does not become sticky after washing.

  Among polyhydric alcohols that have been widely used in cosmetics, glycerin is known to produce a warm feeling due to heat of hydration when in contact with water, and is widely used as a gel cosmetic such as massages and packs. (See Patent Document 1). This glycerin gelation can be achieved by using polysaccharides such as guar gum, locust bean gum, and xanthan gum, semi-synthetic polymers such as hydroxyethyl cellulose, carboxymethyl cellulose, and alginate, synthetic polymers such as polyvinylpyrrolidone, carboxyvinyl polymer, and sodium polyacrylate. Thickener polymers such as molecules are widely used (see Patent Documents 2 and 3).

  However, the gel produced with the thickener polymer increases or decreases in viscosity due to changes in the degree of polymerization of the polymer due to long-term storage, etc. There was a problem that the elongation deteriorated or that oil separation occurred when liquid oil was blended in order to exert a cleansing effect.

  Acyl polypeptides and salts thereof have amphiphilic properties and are known to be used as emulsifiers and liquid crystals (see Patent Document 4). Attempts have been made to add such acyl polypeptides and salts thereof to an external preparation for skin, combined use with a metal ion sealant (see Patent Document 5), combined use with an extract of a plant or the like (see Patent Document 6). , Carboxyvinyl polymer, combined use with alkyl-modified carboxyvinyl polymer (see Patent Document 7), combined use with glycerin monofatty acid ester (see Patent Document 8), etc.
