The Uses of 4,4'-Thiobis(6-tert-butyl-m-cresol)

4,4''-Thiobis(2-tert-butyl-5-methylphenol) is an antioxidant. 4,4''-Thiobis(2-tert-butyl-5-methylphenol) is a radical inhibitor which prevented thermal decomposition of the peracid.

General Description

White or light gray to tan powder.

Air & Water Reactions

Sensitive to base hydrolysis and may spontaneously oxidize in solution. . Insoluble in water.

Reactivity Profile

4,4'-Thiobis(6-tert-butyl-m-cresol) may be sensitive to light.

Hazard

Toxic by inhalation. Upper respiratory tract irritant. Questionable carcinogen.

Health Hazard

4,4'-Thiobis(6-tert-butyl-mcresol) (TBBC) is of low systemic toxicity in animals; allergic contact dermatitis has been reported in humans.

Fire Hazard

4,4'-Thiobis(6-tert-butyl-m-cresol) is combustible.

Flammability and Explosibility

Non flammable

Safety Profile

Poison by intraperitoneal route and probably by ingestion and inhalation. Mutation data reported. See also SULFIDES. When heated to decomposition it emits highly toxic fumes of SOx.

Potential Exposure

This material is used as an antioxidant in the plastics and rubber industries; in Neoprene and other synthetic rubbers; in polyethylene and polypropylene.

Carcinogenicity

TBBC was not mutagenic in Salmonella typhimurium strains with or without metabolic activation. In Chinese hamster ovary cells, TBBC induced an increase in sister chromatid exchanges but there were no increases in chromosomal aberrations.

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. May evolve explosive hydrogen sulfide upon contact with moisture or acids.
