	It has been used in many different commonplace products such as textiles, plastics, electronic equipment.and blown insulation materials such as XPS and EPS, as it helps slow down ignition and spread of flames. In May 2013 the Stockholm Convention on Persistent Organic Pollutants added HBCD to Annex A with specific exemptions for production and use in XPS and EPS in buildings, which countries can apply for a period of up to five years. At the time of writing no exemptions were listed on the [https://chm.pops.int/Default.aspx?tabid=5034 Stockholm Convention webpage], with the last expiring in 2021.

Hexabromocyclododecane (HBCD) is a synthetic white crystalline chemical compound made up of carbon, hydrogen, and bromine atoms in a ring that is used primarily as a flame retardant. The hexa in the name refers to the presence of six bromine atoms in the molecule which are responsible for its flame-retardant properties.

It has been used in many different commonplace products such as textiles, plastics, electronic equipment.and blown insulation materials such as XPS and EPS, as it helps slow down ignition and spread of flames. In May 2013 the Stockholm Convention on Persistent Organic Pollutants added HBCD to Annex A with specific exemptions for production and use in XPS and EPS in buildings, which countries can apply for a period of up to five years. At the time of writing no exemptions were listed on the [https://chm.pops.int/Default.aspx?tabid=5034 Stockholm Convention webpage], with the last expiring in 2021.

It has been classified through various supporting studies as Persistent, Bioaccumulative and Toxic (PBT) meaning a class of chemicals that resist degradation and persist in the environment for long periods. As a result of their persistence, when these chemicals are consumed, they bioaccumulate in the fat tissues, bones, and brain of organisms, it has been detected in air, water, soil, and wildlife.

Alternatives: In response to concerns about HBCD, many manufacturers and industries have sought alternative flame retardants that are less harmful to the environment and human health. Safer alternatives are being developed and used in various applications.

Phase-Out: Some countries have taken steps to phase out or restrict the use of HBCD in certain products, particularly in the production of construction and insulation materials. This is part of efforts to reduce the release of HBCD into the environment.

It's important to note that the use and regulation of HBCD can vary from one region to another. Due to its potential environmental impact and toxicity concerns, there is a growing emphasis on finding safer and more sustainable alternatives for flame-retardant applications.
