Abstract:
1. A composition for lanthionizing keratinous fibers to achieve relaxation of said keratinous fibers comprising: (i) at least one hydroxide compound; (ii) at least one reducing agent chosen from thiols, sulfites, and derivatives thereof; and (iii) at least one complexing agent effective for dissociating the at least one hydroxide compound in a sufficient quantity to effect lanthionization of keratinous fibers, wherein said at least one hydroxide compound and said at least one reducing agent are present in a combined amount effective to relax keratinous fibers, wherein said at least one reducing agent is present in an amount ranging from 0.1% to 5% by weight relative to the total weight of the composition, and with the proviso that if said at least one reducing agent is chosen from cysteine, cysteine derivatives, and thioglycolic acid, said at least one hydroxide compound is present in an amount such that the amount of hydroxide ion is less than 1% by weight relative to the total weight of said composition.
