In Europe, however, trixylyl phosphate is on the REACH SVHC Candidate List (Substance of Very High Concern). The Canada “screening assessment” covers the PIN FR trixylyl phosphate and two other organo-phosphate chemicals. Trixylyl phosphate is used as a PIN flame retardant, and also in food packaging, hydraulic fluids, as a plasticiser, and in wire and cable insulation. The other two chemicals assessed are used in cosmetics and in plastics, rubbers and food packaging. Trixylyl phosphate is considered not to meet the Canada CEPA para. 64(a) or (b) criteria, because it does not enter the environment in concentrations susceptible to have intermediate or long-term harmful effects. Population exposure to trixylyl phosphate, in products and dust, is considered low enough to address uncertainties in exposure and health effects.
