Cas no 5531-65-7 (Octadecanoic acid,phenylmethyl ester)

Octadecanoic acid, phenylmethyl ester (CAS 10289-15-3), also known as benzyl stearate, is a fatty acid ester derived from stearic acid and benzyl alcohol. This compound is characterized by its waxy solid form and low solubility in water, making it suitable for applications requiring hydrophobic properties. It is commonly employed as a lubricant, plasticizer, or emollient in industrial formulations, cosmetics, and personal care products. Its chemical stability and compatibility with organic matrices contribute to its utility in enhancing texture and reducing friction in various systems. The ester's non-reactive nature under standard conditions ensures consistent performance in diverse formulations.
