| Hazard Information | Back Directory | [General Description]
White or light gray to tan powder. | [Reactivity Profile]
4,4'-THIOBIS(6-TERT-BUTYL-M-CRESOL)(96-69-5) may be sensitive to light. | [Air & Water Reactions]
Sensitive to base hydrolysis and may spontaneously oxidize in solution. . Insoluble in water. | [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. | [Fire Hazard]
This chemical is combustible. | [First aid]
Skin Contact: Flood all areas of body that have contacted the substance with water. Don’t wait to remove contaminated clothing; do it under the water stream. Use soap to help assure removal. Isolate contaminated clothing when removed to prevent contact by others. Eye Contact: Remove any contact lenses at once. Flush eyes well with copious quantities of water or normal saline for at least 2030 minutes. Seek medical attention. Inhalation: Leave contaminated area immediately; breathefresh air. Proper respiratory protection must be supplied to any rescuers. IF coughing, difficult breathing or any other symptoms develop, seek medical attention at once, even if symptoms develop many hours after exposure. Ingestion: If convulsions are not present, give a glass or two of water or milk to dilute the substance. Assure that the person’s airway is unobstructed and contact hospital or poison center immediately for advice on whether or not to induce vomiting. | [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. | [Chemical Properties]
4,40-Thiobis(6-tert-butyl-m-cresol) is a light gray to tan powder. Aromatic odor. | [Chemical Properties]
white to almost white crystals or crystalline | [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. | [Flammability and Explosibility]
Nonflammable(100%) | [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. |
