Where is it Commonly Found?
Tris[2-chloro-1-(chloromethyl) ethyl] phosphate (TDCPP) is a major flame retardant used primarily in polyurethane / polyisocyanurate foam, and also used in plastics, resins, and fabric back-coating (OEHHA 2008).
House dust concentrations of TDCPP are associated with altered hormone levels and decreased semen quality in men (Meeker and Stapleton 2010).
The U.S. Consumer Product Safety Commission (Babich 2006) concluded that TDCPP is a probable human carcinogen based on sufficient evidence in animals. TDCPP is genotoxic according to in vitro studies of bacterial and mammalian cells (OEHHA 2011). As of August 2011, TDCPP is under consideration for listing under California’s Proposition 65. It is structurally similar to tris(2-chloroethyl)phosphate, which is already listed as a carcinogen under Proposition 65, and TDCPP metabolizes to several other Proposition 65 substances (OEHHA 2011).
Exposure: TDCPP has been detected in household and office dust, indoor air, and in streams, sewage and sludge; TDCPP has also been found in human adipose tissue, seminal plasma and breast milk (OEHHA 2011).
