Abstract

The object of the present invention is to obtain a gel composition for external skin preparations and cosmetics that is good in skin affinity, has a smooth feeling of use, and is excellent in stability over time, and obtains a gel composition using the composition. Skin external preparations and cosmetics. The gel composition of the present invention includes biosurfactant, polyhydric alcohol, oily component, and ethanol, and the content of ethanol is 0.01% by weight to 10% by weight. The aforementioned biosurfactant is preferably one or more selected from surfactin, nodrolactin, iturin, and salts thereof.

Description

technical field [0001] The present invention relates to a gel composition characterized by containing a biosurfactant such as surfactin, and an external skin preparation and cosmetics using the composition. Background technique [0002] So far, various formulations of cosmetics have been developed. Among them, there are gel compositions (hereinafter, also referred to as "oil-based thickened gel compositions") made by thickening oil-based ingredients, which are used for cleansing cosmetics. Various skin external preparations and cosmetics such as hair cosmetics. As the aforementioned oil-based thickened gel-like composition, conventionally, a composition containing a polyhydric alcohol and a surfactant is known, for example, a biosurfactant containing surfactant or a similar compound thereof, or A gel composition of these salts and a polyhydric alcohol having a valence of 3 or more (Patent Document 1). These gel compositions have good skin affinity and a smooth feeling in u...
