Comments: Polybrominated diphenyl ethers (PBDEs) are non-genotoxic or PTWI because: (1) PBDEs represent a complex group of related chemicals and the May 16, 2008 The primary commercial products of PBDEs are Penta-, Octa-, and Deca-BDEs. Each is a mixture of specific PBDE chemicals or congeners.
Parabens are a group of preservative ingredients used in cosmetic, personal hygiene products, food products and pharmaceuticals.
PBDEs are a class of substances that contain the same base structure but differ in the number of attached bromine atoms. PBDEs do not occur naturally, but are man-made. They are generally produced as commercial mixtures which may contain varying combinations of PBDEs. PBDEs are used as flame retardants to slow the ignition and spread of fire.
Polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) belong to a class of chemicals that are added to certain manufactured products in order to reduce the chances that the products will catch on fire. What are PBDEs? PBDEs are brominated hydrocarbons in which 2-10 bromine atoms are attached to the molecular structure (ATSDR 2015).
PBDEs are a class of substances that contain the same base structure but differ in the number of attached bromine atoms. PBDEs do not occur naturally, but are man-made. They are generally produced as commercial mixtures which may contain varying combinations of PBDEs. PBDEs are used as flame retardants to slow the ignition and spread of fire.
bisphenol A (BPA), and polybrominated diphenyl ether (PBDE), have come under close scrutiny and regulation. Phthalates are plasticizers—softeners used to make plastic products less brittle. Polybrominated diphenyl ether, PBDE, flame retardants are now a world-wide pollution problem reaching even remote areas. They have been found to bioaccumulate and there are concerns over the health effects of exposure to PBDEs, they also have potential endocrine disrupting properties. PeBDE is a mixture with tetra- in which tetra-BDE (TeBDE) is a major component (WHO, 1994). The commercial PBDEs are stable compounds with boiling points ranging between 310 and 425°C.
Polybrominated diphenyl ethers (PBDEs) are a group of brominated flame retardants that are found in a range of widely used consumer products including electronics and electrical equipment (e.g., television sets, computers, printers, fax machines, and cabling); transportation materials (e.g., plastics and upholstery in cars); and textiles (e.g., carpets and upholstery). 1

2001-07-25 · Flame retardants are chemical substances used in various products such as plastics, textiles and furnishing foam to reduce their fire hazards by interfering with the combustion of the polymeric materials. The use of both inorganic and organic flame-retardants has achieved high levels of fire safety (Kuryla and Papa, 1991). PBDEs exist as mixtures of distinct chemicals called congeners with unique molecular structures (ATSDR 2015; EPA 2009). There are three types of commercial PBDE mixtures, including pentabromodiphenyl ether (pentaBDE), octabromodiphenyl ether (octaBDE) and decabromodiphenyl ether (decaBDE).
