PROBLEM TO BE SOLVED: To provide a 4-alkylresorcinol derivative having an excellent bleaching effect and excellent safety. SOLUTION: This 4-alkylresorcinol derivative represented by the general formula (I) (R 1 is a branched alkyl selected from 1-ethylpropyl, 1-ethyl-2-methylpropyl, 1-isopropyl-2-methylpropyl, 1-butylpentyl and 1-isobutyl-3-methylbutyl) or its salt. The 4-alkylresorcinol derivative (I) has a good melamine production-inhibiting effect and low cytotoxicity. The 4-(1-branched alkyl) resorcinol derivative is obtained by reacting a 4-acylresorcinol with an organic metal compound to introduce an alkyl group into the carbonyl carbon, and then reducing the product.
