Carcinogenicity Data: No adverse reproductive effects are anticipated. Reproductive Data: No adverse mutagenic effects are anticipated. Mutagenicity Data: No adverse teratogenic effects are anticipated. Teratogenicity Data: May cause skin sensitization or other allergic responses. Sensitization is the process whereby a biological change occurs in the individual because of previous exposure to a substance and, as a result, the individual reacts more strongly when subsequently exposed to the substance. Once sensitized, an individual can react to extremely low airborne levels, even below the TLV, or to skin contact. Respiratory / Skin Sensitization Data: None known. Synergistic Materials: tert-Butyl Mercaptan: Inhalation exposure of rats to 9, 97 or 196 ppm tert-Butyl Mercaptan for 90 days produced kidney disease in males. (4) Tert-Butyl Mercaptan gave positive results in the mouse lymphoma forward mutation assay (in vitro). (4) In rodents, acute poisoning by tert-Butyl Mercaptan produced a pattern of central nervous system depression, muscular paralysis and tremors. Skin allergy was observed in guinea pigs following repeated exposure. Following repeated inhalation exposures, mild to moderate lever effect (hypertrophy) and mild kidney effects (proximal tubular nephrosis in males only) were observed in rats. No birth defects were noted in tests using bacteria or animals. Both positive and negative responses have been reported in tests using animal cells. (3) Other Studies Relevant to Material: 12.
