Claims38
A skin tanning composition which comprises:
- (a) dihydroxyacetone;
- (b) an azole having the structure ##STR5## wherein X=S, O, or NR.sup.1, and R.sup.1 through R.sup.4 can be the same or different and are hydrogen;
- phenyl;
- C.sub.1 -C.sub.6 alkyl unsubstituted or substituted by phenyl, hydroxyl, carboxy, benzyloxy, amino, halogen, carboxylic acid, sulfonate or phosphonate;
- or --CH.sub.2 --CH(COOR')NR"R"' where R', R" and R"' are the same or different and are hydrogen or C.sub.1 -C.sub.4 alkyl;
- and
- (c) a cosmetically or pharmaceutically acceptable carrier.
A skin tanning composition which comprises:
- (a) from about 1.0 to about 20 percent by weight of the total composition of dihydroxyacetone;
- (b) from about 1.5 to about 7.5 percent by weight of the total composition of an azole having the structure ##STR6## wherein X=S, O, or NR.sup.1, and R.sup.1 through R.sup.4 can be the same or different and are hydrogen;
- phenyl;
- C.sub.1 -C.sub.6 alkyl unsubstituted or substituted by phenyl, hydroxyl, carboxy, benzyloxy, amino, halogen, carboxylic acid, sulfonate or phosphonate;
- or --CH.sub.2 --CH(COOR')NR"R"' where R', R" and R"' are the same or different and are hydrogen or C.sub.1 -C.sub.4 alkyl;
- (c) an organic acid present in an amount by weight of the total composition sufficient to lower the pH of the composition to from about 3 to about 5;
- and
- (d) a cosmetically or pharmaceutically acceptable carrier.
A method for artificially tanning human skin which comprises applying to the skin dihydroxyacetone and an azole having the structure ##STR7## wherein X=S, O, or NR.sup.1, and R.sup.1 through R.sup.4 can be the same or different and are hydrogen;
- phenyl;
- C.sub.1 -C.sub.6 alkyl unsubstituted or substituted by phenyl, hydroxyl, carboxy, benzyloxy, amino, halogen, carboxylic acid, sulfonate or phosphonate;
- or --CH.sub.2 --CH(COOR')NR"R"' where R', R" and R"' are the same or different and are hydrogen or C.sub.1 -C.sub.4 alkyl.
