Toxic substances list: hexabromocyclododecane (HBCD)

Hexabromocyclododecane, which has the molecular formula C12H18Br6 (HBCD), is a brominated flame retardant. Brominated flame retardants are organic compounds containing bromine that slow the ignition and spread of fire.

HBCD was found primarily in expanded (EPS) and extruded (XPS) polystyrene foam used as an insulation material in the building industry (approximately 99% of its historical use). There were also a number of other minor uses as a flame retardant, such as in textiles used for upholstered furniture and upholstered seating in transportation, and in wall coverings and draperies. It was also used in some glues, paints, adhesives and polymers contained in electronic equipment. The only known intentional use of HBCD in products in Canada is within the automotive sector. Although, HBCD may also be present in products made from recycled plastics including toys.
