Abstract:
1. A method for treating hair, wherein the hair comprises two or more free thiol groups, comprising: (a) applying to the hair a formulation comprising a binding agent of Formula I wherein A, B, C, and D are reactive moieties capable of reacting with the free thiol groups and contain one or more charges, and wherein each of A, B, C, and D independently contains a moiety selected from the group consisting of a vinyl sulfone, an acrylate group, a methacrylate group, a styrene group, an acryl amide group, a methacryl amide group, a maleate group, a fumarate group, and an itaconate group; R is a linker that contains two or more charges, wherein the charges are opposite to the charges on the reactive moieties, wherein n=1-10, and wherein R is not a polymer, and wherein the sum of the charges is zero; and wherein the reactive moieties are ionically bound to the linker; wherein each occurrence of p, q, r, and s is independently an integer from 0 to 25, wherein the sum of p+q+r+s is equal to or greater than 2, in an effective amount to covalently bind the free thiol groups.
