Description
Isononyl isononanoate (CAS 59219-71-5, EC 261-665-2) is a branched-chain ester produced by reacting isononanol with isononanoic acid. It carries no E-code designation and is commercially known under trade names including Wickenol 151. It belongs to the oils, fats, and waxes category of specialty esters.
In personal care formulations, it functions as an emollient carrier and solvent, solubilising active ingredients and spreading them evenly across skin without a greasy residue. In pharmaceutical topical preparations, it acts as a plasticiser and skin-conditioning agent, improving film flexibility in transdermal delivery systems and enhancing penetration of co-formulated actives.
Isononyl isononanoate is supplied in cosmetic and pharmaceutical grades and is subject to REACH registration requirements within the European Economic Area. Procurement teams should confirm supplier compliance documentation, including safety data sheets and certificates of analysis. Standard packaging formats include drums and intermediate bulk containers.
