Abstract
Abstract Deodorant compositions containing at least one zinc or magnesium salt of a polyacid of the general formula: ##STR1## in which X is--CH═CH--or--CHOH--CHOH--, Y is H, a saturated or unsaturated aliphatic radical of 1 to 10 carbon atoms, which is unsubstituted or substituted by one or more hydroxyls, a saturated or unsaturated alicyclic radical of up to 30 carbon atoms, which is unsubstituted or substituted by one or more hydroxyls and/or a carboxylic acid group, or Y denotes a carboxylic acid radical when p=O, Z denotes a saturated or unsaturated hydrocarbon radical of up to 6 carbon atoms, n is an integer less than 10, p is O or an integer less than or equal to n, and R is H or a lower alkyl group, and of a positional isomer of such a polyacid, exhibit the advantage that they prevent the development of odors without thereby destroying the biological equilibrium of the skin. The compositions may be in the form of creams, lotions, solids, such as roll-on blocks, sticks or compacted powders, aerosols and the like.
