2-Ethylhexyl diphenyl phosphate

2-Ethylhexyl diphenyl phosphate (CAS 1241-94-7) is an organophosphate ester plasticizer and flame retardant sold under trade names including Octicizer, Disflamoll, Phosflex 342, Phosflex 362, and Santicizer 141. It carries no E-code designation and is identified under EC number 214-987-2 with molecular formula C20H27O4P.

In PVC and vinyl formulations, it functions as a primary plasticizer while simultaneously imparting flame retardancy through phosphorus-based gas-phase and char-forming mechanisms. In industrial lubricants and metalworking fluids, it reduces friction at metal interfaces and improves thermal stability. Coatings and adhesive formulators use it to control film flexibility and reduce flammability ratings.

This substance is subject to REACH registration requirements within the European Economic Area and should be handled in accordance with the applicable SDS. It is supplied in standard industrial drum and IBC formats. Procurement teams should confirm current regulatory status and any applicable restrictions before specification.
