Abstract

The process of suppressing body odor by applying to the skin a topical composition containing fat-soluble hydroxycarboxylic acid esters obtained by esterification of polybasic, optionally acetylated hydroxycarboxylic acids containing 3 to 6 carbon atoms by reaction with fatty acids containing 12 to 30 carbon atoms, fatty acid esters of C.sub.12-22 fatty acids and C.sub.1-4 alcohols or with hydroxyl compounds selected from the group consisting of PA1 (a) fatty alcohols containing 12 to 30 carbon atoms, PA1 (b) fatty acid esters of C.sub.12-22 fatty acids and polyols containing 2 to 6 carbon atoms and 2 to 6 hydroxyl groups, PA1 (c) epoxyalkanes containing 12 to 30 carbon atoms, PA1 (d) alkyl glycosides corresponding to the formula R.sup.1 O(C.sub.6 H.sub.10 O).sub.x --H, in which R.sup.1 is an alkyl group containing 8 to 16 carbon atoms and x representing the average degree of oligomerization of the glycoside unit (C.sub.6 H.sub.10 O), has a value of 1 to 4, and PA1 (e) adducts of 1 to 8 moles of ethylene oxide with the hydroxyl compounds (a) to (d).
