ABSTRACT:
A hair relaxant and process in which water-soluble disulfides are added to water-soluble mercaptans, used as reducing agents, to shift the equilibrium point of the relaxer toward the reactants sufficiently such that the relaxant will not cause damage to the hair. The ingredients are carried in a viscous creme base, and there is an absence of sulfite and bisulfite salts. This is followed by rinsing and the use of an oxidizing neutralizer. The process is carried out in the absence of added heat.
