78-42-2
Product name: Tris(2-ethylhexyl) phosphate
English alias: TOP; Tri(2-ethylhexyl) phosphate; TOF; Phosphoric acid trioctyl ester
CAS: 78-42-2
Molecular formula: C24H51O4P
Appearance: Colorless to pale yellow transparent oily liquid
Package: 200kg/drum, 1000kg/IBC drum
It is a synthetic aliphatic phosphate ester widely utilized as a flame retardant, plasticizer, and functional fluid additive. It is particularly valued for its excellent low-temperature performance, low volatility, and hydrophobic properties. Compared to aromatic phosphate esters, TOP offers superior resistance to hydrolysis and ultraviolet (UV) light stability, making it suitable for applications requiring long-term durability. It is compatible with a wide range of polymers and resins. Its chemical formula is C₂₄H₅₁O₄P, and it typically appears as a colorless to pale yellow, clear, oily liquid with a mild characteristic odor.

1. Flame Retardant Plasticizer: Tris(2-ethylhexyl) phosphate used as a flame-retardant plasticizer in PVC, nitrocellulose, and synthetic rubber, especially valued for its excellent low-temperature flexibility in vinyl applications.
2. Hydraulic Fluids & Lubricants: Tris(2-ethylhexyl) phosphate serves as a base stock or anti-wear additive in high-performance, fire-resistant hydraulic fluids and synthetic lubricants due to its thermal stability and lubricity.
3. Extractant & Solvent: Tris(2-ethylhexyl) phosphate employed as a solvent and extractant in metallurgical processes for the separation of rare earth metals and other metal ions.
4. Cosmetics Industry:Tris(2-ethylhexyl) phosphate functions as a plasticizer and emollient in nail polishes and other cosmetic formulations (requires high-purity grades).
5. Engineering Plastics:Tris(2-ethylhexyl) phosphate acts as a processing aid and flame retardant in various engineering plastics.
6.Rubber Industry: Used as a plasticizer to improve the low-temperature properties and processability of synthetic rubbers.
Cresyl Diphenyl Phosphate (CDP) is generally considered to have lower toxicity compared to tricresyl phosphate (TCP). However, it may still cause mild skin and eye irritation. Repeated or prolonged skin contact may cause dryness. It is recommended to avoid ingestion and inhalation of mists or vapors. Always handle with appropriate personal protective equipment (PPE) including gloves and safety glasses. Ensure good ventilation in the work area. As with all chemicals, please consult the Safety Data Sheet (SDS) for comprehensive handling, first-aid, and disposal information before use.
Store in a tightly closed container in a cool, dry, and well-ventilated place.
Keep away from heat, sparks, open flames, and strong oxidizing agents.
Trioctyl Phosphate is typically packaged in 200kg steel drums or 1000kg IBC totes. It is not typically classified as a dangerous good for transport under most regulations (e.g., ADR, IMDG, IATA) in its pure form. However, it is always the shipper's responsibility to classify the product according to the most current regulations and the specific product specification.
