Description
Ethylparaben Sodium (CAS 35285-68-8), also known as Sodium Ethylparaben or E215, is the sodium salt form of ethylparaben. It carries EC number 252-487-6 and the molecular formula C9H10O3.Na. As a water-soluble paraben derivative, it is classified under Salts & Minerals and traded under the E215 designation in food and cosmetic contexts.
In personal care formulations, it functions as a preservative by disrupting microbial cell membranes, inhibiting bacterial and fungal growth at low concentrations. In food and pharmaceutical applications, it acts as an antimicrobial agent to extend shelf life. It also serves as a UV absorber and skin conditioner in topical cosmetic systems.
Ethylparaben Sodium is available in pharmaceutical and food-grade forms, compliant with Ph.Eur., FCC, and REACH regulations. It is supplied as a crystalline powder under HS code 2918 29 00, typically in fiber drums or multi-layer bags suited for hygroscopic materials.
