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.

Abstract: A composition for the cosmetic treatment of human skin, particularly facial skin, to remove retention products from the skin surface and sebaceous follicles, is disclosed. The composition comprises a high-silica zeolite, the principal adsorbent constituent, dispersed in an aqueous medium using colloidal hectorite-type clays, a water soluble alkyl polyol preferably having from 2 to 6 hydroxyl groups, and most preferably a glycol such as propylene glycol, and an anti-microbial agent compatible with the high-silica zeolite.
