Claim:
A composition comprising: a) a sunless tanning agent; and b) an adjuvant for the sunless tanning agent, the adjuvant comprising a vicinal primary diamine having the formula wherein a and b are each independently zero or 1; R is H, or C 1-4 alkyl when a is zero and CH—X when a is 1; R 1 is H or C 1-4 alkyl when b is zero and CH—X when b is 1; when a is 1, R 2 is H, C 1-4 alkyl or a C 1-3 alkoxy when b is zero, and CH—X or Y when b is 1; when b is 1, R 3 is H, C 1-4 alkyl or a C 1-3 alkoxy when a is zero, and CH—X or Y when a is 1; each X is independently H, OH, C 1-3 alkyl or —CH 2 (CH 2 ) n OH where n is an integer from zero to 2; Y is oxygen or NR 4 ; and each R 4 is independently H, C 1-6 alkyl, aryl or —CH 2 —(CH 2 ) m —OH where m is an integer from about 0 to about 4; wherein at least about 50% by weight of the vicinal diamine present is not loaded onto a microparticle delivery system, wherein the vicinal diamine comprises 1,2-diamino cyclohexane, and wherein the adjuvant further comprises Vitamin E and/or a derivative thereof.
