ABSTRACT:
Treatment of human or animal hair for purposes of waving, straightening or softening using compositions containing thioglycolic acid compounds commonly leave an undesirable odor due to the presence of residual trace amounts of the thio compound. The compositions of the present invention contain siliceous crystalline molecular sieves either as the sole active ingredient or in combination with hair conditioners. When applied to hair containing conventional, acid or soft wave hair perming solutions, the molecular sieve constituent effectively adsorbs and holds the residual odor-causing thioglycolic acid compound so that its odor is reduced to below its olfactory detection level threshold.
