Composition, process for preparation and method of use
First Claim
1. A depilatory composition comprising an emulsion of hydrophobic particles in a continuous aqueous phase, whereinthe continuous aqueous phase comprises a depilatory agent,the hydrophobic particles consist of a fatty alcohol and a vinylpyrrolidone/hexadecene copolymer,the depilatory agent is a sulfhydryl compound, andthe inclusion of a vinylpyrrolidone/hexadecene copolymer and a fatty alcohol in a hydrophobic particle provide adherence qualities of the composition to hairy skin such that the composition has a degradation period greater than three minutes, wherein the degradation period is the time the composition is left in contact with hairy skin to achieve adequate hair degradation even when rinsed or immersed in water,the vinylpyrrolidone/hexadecane copolymer is in an amount of about 1.9% by weight of the total composition,the vinylpyrrolidone/hexadecane copolymer has a molecular weight in the range of 6,500 to 8,500 mass units, andthe vinylpyrrolidone/hexadecane copolymer is a polymer with the structure (C22H41NO)x.

Abstract
Depilatory compositions comprising a depilatory agent, fatty alcohol and VP/hexadecene copolymer provide improved resistance to rinsing of the compositions from the skin. The compositions provide for a method-of depilation in wet conditions using a tool to apply and remove the compositions.
