GHS Hazard Classification

Documented Uses

• Polybrominated diphenyl ethers (PBDEs) are flame-retardant chemicals found in plastics used in a variety of consumer products to make them difficult to burn. Because they are mixed into plastics and foams rather than bound to them, PBDEs can leave the products that contain them and enter the environment. (L628)
• Benzene, 1,1'-oxybis[4-bromo-: ACTIVE
• Polybrominated biphenyls can be absorbed through oral, inhalation, and dermal routes. Once in the body they distribute throughout and bioaccumulate in the blood, breast milk, and adipose tissue. The extent of PBDE metabolism depends on the degree of bromination. Metabolism is believed to involve debromination and methylation, resulting in phenolic metabolites. Metabolized and unmetabolized PDBE compounds are excreted mainly in the faeces. (L628, L881)
