PURPOSE:An external preparation of the skin such as cosmetic, quashi-drug, etc., having improved greasiness perculiar to water-soluble high polymer and improved sliding feeling when applied to the skin, obtained by blending a water- soluble high polymer with a specific hydroquinone glycoside. CONSTITUTION:An external preparation for the skin containing a water-soluble high polymer (preferably 0.1-1wt% based on the total amounts of the external preparation of the skin) such as gum arabic, pectin, xanthan gum, collagen, carboxymethyl starch, methyl celluose, polyvinyl alcohol, polyacrylic acid, etc. and about 6-20wt% hydroquinone glycoside (most preferably hydroquinone-beta-D- glucose) shown by the formula (R is pentasaccharide residue, hexasaccharide residue, amino sugar residue, uronic acid residue, or methylated group of these residues). EFFECT:The preparation has improved stability, feeding in use, humectant effects on the skin and improved safety. |
