Abstract

PURPOSE:An external preparation for the skin useful as cosmetic, drug, quasi- drug, etc., having improved stability free from change in color with day, obtained by blending a specific hydroquinone glycoside having beautifying action with vitamin E. CONSTITUTION:An external preparation for the skin containing one or more selected from hydroquinone glycosides (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) and one or more selected from vitamins (e.g., alpha-tocopherol, nicotinic acid tocopherol, etc.). Preferably the amount of the hydroquinone glycoside blended is 6-20wt% and the amount of the vitamin E blended is 0.05-0.2wt% based on the total amounts of the external preparation for the skin.
