Description
An aromatic phosphate that was commonly used as a Flame retardant and Plasticizer. Triphenyl phosphate (TPhP) was placed on the EPA Toxic Substance list in 2014 as a compound that exhibits acute and chronic aquatic toxicity. As a flame retardant, TPhP decomposes with heat to form Phosphoric acid, then further reacts to form pyrophosphoric acid which acts as a heat transfer blocker. In industry, TPhP is considered to be one of the most effective flame retardant for certain polymers, such as polyvinylchloride.
Synonyms and Related Terms
TPhP; TPP
Applications
- Plasticizer often used in glues, varnishes, nail polishes, and casting resins
- Flame retardant in electronic equipment, hydraulic fluids and plastics
Risks
- Low toxicity by dermal and oral contact but some studies have lined TPhP to reproductive and developmental toxicity, neurotoxicity, metabolic disruption, and endocrine effects.
- Widely detected in sediment, soil, indoor dust, and air due to its extensive use.
- Biodegrades in water.
Physical and Chemical Properties
- Chemical formula = C18H15O4P
