HBCD (Hexabromocyclododecane)

Hexabromocyclododecane (HBCD) is a synthetic chemical used as a flame retardant, mainly in building insulation materials like foam, textiles, and plastics. It helps reduce the risk of fire but is persistent in the environment, meaning it doesn't break down easily. HBCD can accumulate in living organisms, including humans, and has been linked to potential health concerns such as hormonal disruption and developmental effects. Due to these risks, many countries have regulated or restricted its use, encouraging safer alternatives for fire-resistant materials.
