1. Hexabromocyclododecane

   Hexabromocyclododecane is a brominated flame retardant. It consists of twelve carbon, eighteen hydrogen, and six bromine atoms tied to the ring. Its primary application is in extruded and expanded polystyrene foam that is used as thermal insulation in the building industry. HBCD is highly efficient in this application so that very low levels are required to reach the desired flame retardancy. Typical HBCD levels in EPS are 0.7% and in XPS 2.5%. At present, according to BSEF, the brominated flame retardant industry panel, HBCD is the only suitable flame retardant for these applications. Any other flame retardant would likely need higher load levels in the polystyrene foam. Other uses are upholstered furniture, automobile interior textiles, car cushions and insulation blocks in trucks, packaging material, video cassette recorder housing and electric and electronic equipment. According to UNEP, “HBCD is produced in China, Europe, Japan, and the USA. The known current annual production is approximately 28,000 tonnes per year. The main share of the market volume is used in Europe and China”. HBCD's toxicity and its harm to the environment are currently discussed. HBCD can be found in environmental samples such as birds, mammals, fish and other aquatic organisms as well as soil and sediment. On this basis, on 28 October 2008 the European Chemicals Agency decided to include HBCD in the SVHC list, Substances of Very High Concern, within the Registration, Evaluation, Authorisation and Restriction of Chemicals framework. HBCD has been found widely present in biological samples from remote areas and supporting evidences for its classification as Persistent, Bioaccumulative and Toxic and undergoes long-range environmental transportation. In July 2012, an EU harmonised classification and labelling for HBCD entered into force. HBCD has been classified as a category 2 for reproductive toxicity. Since August 2010 hexabromocyclododecanes are included in the EPA's List of Chemicals of Concern. On 19 October 2012 the Persistent Organic Pollutants Review Committee, a subsidiary body of the Stockholm Convention on Persistent Organic Pollutants, adopted a recommendation to include HBCD in the Convention’s Annex A for elimination, with specific exemptions for expanded and extruded polystyrene needed to give countries time to phase-in safer substitutes. Final descision will be taken in May 2013.
