Description
Triisobutyl phosphate, commonly abbreviated as TiBP, is an organophosphate ester supplied as a clear oily liquid. It carries CAS number 126-71-6 and EC number 204-798-3, and is also referenced under the names tri-isobutylphosphate and Triisobutylphosphat in European trade documentation. No E-code designation applies to this substance.
In polymer and coatings formulations, TiBP functions as a flame retardant by releasing phosphoric acid species during combustion, interrupting the oxidation chain reaction in the gas phase. It also serves as an effective defoamer in industrial coatings and printing inks, where its low surface tension disrupts foam stabilisation at the air-liquid interface. In personal care applications, it acts as a solvent and carrier for fragrance compounds.
TiBP is available in standard industrial grades and is subject to REACH registration requirements within the European Economic Area. It is classified under HS code 2919 90 00 for customs purposes. Procurement teams should confirm SDS documentation and packaging formats directly with the supplier.
