Description
Butyl benzoate (CAS 136-60-7, EC 205-252-7), also listed as benzoic acid butyl ester or n-butyl benzoate, is an ester formed from benzoic acid and n-butanol. It carries no assigned E-code and is not classified as a food additive. It is registered under REACH and handled accordingly across EU supply chains.
In personal care formulations, butyl benzoate functions as a plasticiser and emollient carrier, improving spreadability while contributing mild preservative activity against microbial growth. In polymer and plastics processing, it acts as a plasticising solvent and process aid, lowering viscosity during compounding. It also serves as a UV-absorber co-solvent in sunscreen and coating systems.
Butyl benzoate is supplied in technical and cosmetic grades, with cosmetic-grade material meeting REACH compliance requirements for EU market entry. Standard packaging includes drums and IBC containers. Procurement teams should confirm grade specification against intended application, as purity thresholds differ between personal care and industrial uses.
