Claim Text:
1. A cosmetic composition comprising: at least one non-nitrogenous zinc salt, and at least one cationic surfactant chosen from the following quaternary ammonium salts and mixtures thereof: quaternary ammonium salts of formula (I): in which the radicals R in which: R R R R r, s and t, which may be identical or different, are integers ranging from 2 to 6; r1 and t1, which may be identical or different, are equal to 0 or 1, r2 and t2 are integers such that r2+r1=2r and t1+t2=2t; y is an integer ranging from 1 to 10; x and z, which may be identical or different, are integers ranging from 0 to 10; X with the provisos that the sum x+y+z ranges from 1 to 15, that when x is 0, then R wherein the weight ratio of the amount of the at least one cationic surfactant to the amount of the at least one zinc salt is less than or equal to 1, and wherein the weight ratio of the amount of the at least one cationic surfactant to the amount of the zinc element ranges from about 0.005 to about 10.
