ABSTRACT OF THE DISCLOSURE Disclosed is a chemical composition for external application, which comprises a kojic acid or kojic acid derivative and an unsaturated linear fatty acid having from 4 to 26 carbon atoms and having from 1 to 6 unsaturated bonds where the position(s) of the unsaturated bond(s) is(are) any desired position(s) in the alkyl chain of the acid except the terminal opposite to the carboxyl group thereof or a derivative thereof as active ingredients. By the synergistic effect of the two active ingredients, the composition is effective for noticeably preventing formation of melanin to cause freckles and spots in the skin and for noticeably whitening the skin. - 27 -
