Structured depilatory compositions
View Patent ↗Provided are compositions comprising a depilatory active; and a surfactant, wherein the composition has a Yield Stress of from about 1 Pascal (Pa) to about 1500 Pa, and methods of use thereof.
1. A composition comprising:
a depilatory active; and
about 2 to about 30% by weight of an anionic surfactant which may be branched or unbranched and is selected from the group consisting of alkyl olefin sulfonates, alkyl sulfates, alkyl ether sulfates, alkyl monoglyceryl ether sulfates, alkyl sulfonates, alkylaryl sulfonates, alkyl sulfosuccinates, alkyl ether sulfosuccinates, alkyl sulfosuccinamates, alkyl amidosulfosuccinates, alkyl carboxylates, alkyl amidoethercarboxylates, alkyl succinates, fatty acyl sarcosinates, fatty acyl amino acids, fatty acyl taurates, fatty alkyl sulfoacetates, alkyl phosphates, and mixtures of two or more thereof; and
about 0.1 to about 10% by weight of a structuring aid selected from the group consisting of C 11 -C 15 linear branched fatty acids or fatty alcohols,
wherein the composition has an H-B dimension of less than about 1.7 and a pH of from about 7.5 to about 13 and further wherein the composition is substantially free of surfactants comprising one or more amide functional groups.
2. The composition of claim 1 , wherein the surfactant is an alkyl olefin sulfonate.
3. The composition of claim 1 , wherein the composition further comprises a monobranched fatty alcohol.
4. A method of making a structured composition of claim 1 comprising combining a depilatory active, the anionic surfactant, and the structuring aid in amounts sufficient to achieve a composition having an H-B dimension of less than about 1.7 and a pH of from about 7.5 to about 13.
5. A method of removing hair from the human body comprising applying to a portion of the human body in need of removing hair a structured composition of claim 1 .
6. The composition of claim 1 wherein the depilatory active is selected from the group consisting of thioglycolates.
7. The composition of claim 1 having a pH of from about 11 to about 13.
8. The composition of claim 5 having a pH of from about 11 to about 13.
