  • What is tricresyl phosphate (TCP)?
  • See more... THIS chapter reviews the physical and chemical properties, toxicokinetics, toxicological, epidemiological, and exposure data on tricresyl phosphate (TCP), an aromatic phosphate ester. TCP is one of several aromatic phosphate esters used commercially as flame retardants and plasticizers.
  • Is tricresyl phosphate a flame retardant?
  • The subcommittee also identified data gaps and recommended research relevant for determining the health risk from exposure to TCP. Tricresyl phosphate (TCP) is one of several aromatic phosphate esters used commercially as a flame retardant. The physical and chemical properties of TCP are summarized in Table 17–1.
  • Is TCP a flame retardant?
  • TCP is one of several aromatic phosphate esters used commercially as flame retardants and plasticizers. TCP was chosen as the representative aromatic phosphate ester flame retardant for risk assessment because it has the most complete toxicity database. The subcommittee used that information to characterize the health risk from exposure to TCP.
  • Do aromatic phosphate esters have a dermal RfD for TCP?
  • Quantitative toxicity assessments of aromatic phosphate esters was estimated using toxicity data for TCP. Therefore, these assessments will be overly conservative for the toxicity of other aromatic phosphate esters. No studies were identified that could be used to derive a dermal RfD for TCP.
  • What are the physical and chemical properties of TCP?
  • The physical and chemical properties of TCP are summarized in Table 17–1. Physical and Chemical Properties for Tricresyl Phosphate (TCP), Mixed Isomers. Commercial TCP is a complex mixture containing the meta TCP (TMCP) and para TCP (TPCP) isomers and mixed tricresyl and dicresyl phosphate esters.
  • Is TCP a toxic hazard?
  • A hazard index of 4.3×10 −2 was calculated by dividing the estimated daily dermal dose of 3.0×10 −3 mg/kg-d by the oral RfD for TCP of 0.07 mg/kg-d. These results suggest that TCP is not anticipated to be a toxic risk by the dermal route at the stated application concentrations and under the worst-case exposure scenario.
