Transparent self-tanning gels containing a water-soluble/dispersible acrylamido-2-methylpropanesulfonic acid polymer

摘要

Topically applicable, stable, transparent self-tanning aqueous gels, suited for artificially tanning and/or browning human skin, contain at least one self-tanning agent and at least one water-soluble or water-dispersible, crosslinked or non-crosslinked (co)polymerizate of at least the acrylamido-2-methylpropanesulfonic acid (AMPS) monomer, or partially or totally neutralized form thereof, formulated into a topically applicable, cosmetically acceptable support therefor.

主权项

1. A topically applicable, cosmetically acceptable, stable, transparent self-tanning aqueous gel, suited for artificially tanning and/or browning human skin, comprising at least one monocarbonyl or polycarbonyl self-tanning agent and at least one water-soluble or water-dispersible, non-crosslinked copolymer comprising at least an acrylamido-2-methylpropanesulfonic acid monomer, in a form partially or totally neutralized with a mineral base other than ammonia, said copolymer being selected from the group consisting of:
(i) copolymers formed from an acrylamido-2-methylpropanesulfonic acid monomer and vinylpyrrolidone or vinylformamide; (ii) copolymers formed from an acrylamido-2-methylpropanesulfonic acid monomer and sodium acrylate; and (iii) copolymers formed from an acrylamido-2-methylpropanesulfonic acid monomer and hydroxyethyl acrylate; formulated into a topically applicable, cosmetically acceptable support; said gel having a turbidity of less than 400 NTU.
