METHOD FOR PRODUCING COSMETIC, METHOD FOR PREPARING GEL FOR COSMETICS, AND METHOD FOR REDUCING QUANTITY OF HIGH-MOLECULAR THICKENER ADDED TO STARTING MATERIALS OF COSMETIC

摘要

There is provided a production method of a cosmetic, a preparation method of a gel for cosmetics, and a method of reducing the use amount of a polymer thickener blended in cosmetic raw materials. The present invention relates to a production method of a cosmetic comprising blending, into the cosmetic raw material in addition to the polymer thickener, at least one lipid peptide-type gelator that contains a low-molecular lipid peptide or a pharmaceutically usable salt thereof at a ratio of 0.1% by weight to 0.5% by weight based on a mass of the polymer thickener to form a thickening gel; a preparation method of a gel for cosmetics comprising blending, into an aqueous medium for cosmetics, a polymer thickener and at least one lipid peptide-type gelator that contains a low-molecular lipid peptide or a pharmaceutically usable salt thereof at the above-mentioned ratio to form a gel; and a method of reducing the use amount of a polymer thickener in production of a cosmetic comprising blending, into the cosmetic raw material in addition to the polymer thickener, at least one lipid peptide-type gelator that contains a low-molecular lipid peptide or a pharmaceutically usable salt thereof at the above-mentioned ratio.
