Tris(1-chloro-2-propyl) phosphate: A Comprehensive Overview
Tris(1-chloro-2-propyl) phosphate (TCPP) is an organophosphate flame retardant plasticizer that finds extensive use in a wide range of industrial applications. TCPP is manufactured and supplied by INNO Specialty Chemicals, a leading chemical manufacturer and supplier based in China. In this article, we will provide a comprehensive overview of TCPP, including its properties, applications, environmental and human health concerns, and regulations.
Properties of TCPP
TCPP is a colorless liquid with a faint odor. It has a molecular weight of 327.6 g/mol and a boiling point of 387°C. TCPP is soluble in organic solvents such as ethanol, acetone, and chloroform. It is also miscible in water at low concentrations. TCPP is stable under normal conditions but can decompose when exposed to high temperatures or flames, releasing toxic gases such as hydrogen chloride, carbon monoxide, and phosphorus oxides.
Applications of TCPP
TCPP is primarily used as a flame retardant plasticizer in various polymers, including polyvinyl chloride (PVC), polyurethane (PU), and polyolefins. TCPP improves the fire resistance of these materials by reducing their flammability and delaying their ignition and spread. TCPP is also used as a lubricant, viscosity modifier, and anti-static agent in industrial fluids, such as hydraulic fluids, cutting oils, and greases.
Environmental and Human Health Concerns
TCPP has been classified as a Category 2 reproductive toxicant by the European Chemicals Agency (ECHA) due to its potential to cause adverse effects on fertility and development. TCPP is also a suspected carcinogen and neurotoxicant based on animal studies. Moreover, TCPP is persistent, bioaccumulative, and toxic (PBT) in the environment, meaning that it can accumulate in living organisms and cause harm over time.
Regulations for TCPP
TCPP is regulated by various international and national authorities, including the ECHA, the United States Environmental Protection Agency (EPA), and the Chinese Ministry of Ecology and Environment (MEE). In the European Union (EU), TCPP is included in the Candidate List of Substances of Very High Concern (SVHC) due to its hazards to human health and the environment. TCPP is also subject to the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation, which requires manufacturers and importers to submit data on the properties and uses of the chemical and to implement risk management measures. In the United States, TCPP is listed as a toxic chemical under the Toxic Substances Control Act (TSCA), and its use is restricted in certain consumer products, such as children's toys and furniture. In China, TCPP is subject to the Law on the Prevention and Control of Environmental Pollution by Solid Wastes, which prohibits the import and use of PBT chemicals, including TCPP, in certain industries and products.
Conclusion
Tris(1-chloro-2-propyl) phosphate is a widely used flame retardant plasticizer with various industrial applications. However, TCPP poses significant environmental and human health concerns, including its persistence, bioaccumulation, and toxicity. Therefore, it is essential to regulate and manage the production, use, and disposal of TCPP to minimize its adverse effects. As a responsible chemical manufacturer and supplier, INNO Specialty Chemicals is committed to complying with all applicable regulations and promoting the sustainable use of TCPP and other chemicals.
