Dodecyl benzoate

Dodecyl benzoate, also known as lauryl benzoate or benzoic acid lauryl ester (CAS 2915-72-2), is a benzoic acid ester formed by reacting benzoic acid with dodecanol. It carries no assigned E-code. It is used across personal care, polymer, and lubricant formulations as a functional ester ingredient.

In cosmetic formulations, dodecyl benzoate functions as a non-greasy emollient carrier that improves spreadability and solubilises active ingredients such as UV filters and fragrance compounds. In plastics processing, it acts as a plasticizer, reducing polymer chain rigidity to improve flexibility and workability. In metalworking fluids, it contributes lubricity through its ester-based film-forming behaviour.

Dodecyl benzoate is supplied as a liquid ester and is subject to REACH registration requirements for EU market supply. Procurement teams should confirm supplier documentation including Safety Data Sheets and certificates of analysis. Packaging formats typically include drums and intermediate bulk containers depending on order volume.
