Tris(2-chloroethyl) phosphate (TCEP) is a chemical compound used as a flame retardant, plasticizer, and viscosity regulator in various types of polymers including polyurethanes, polyester resins, and polyacrylates.[2]


Because of its suspected reproductive toxicity, it is listed as a substance of very high concern under the European Union's REACH regulations.
