Decyl oleate

Decyl oleate (CAS 3687-46-5) is a fatty acid ester derived from oleic acid and decanol, used across personal care and industrial formulations as an emollient, carrier, and lubricant. It delivers a lightweight, non-greasy skin feel in cosmetic applications while providing effective lubricity in industrial systems. In personal care, it functions as an emollient and solvent carrier.

It is commonly used in skin creams, lotions, sunscreens, and color cosmetics, where it improves spreadability and active ingredient delivery. Industrial lubricant formulators use it as a bio-based base fluid. It serves as an additive in metalworking fluids, where its ester structure provides boundary lubrication and reduces friction on metal surfaces. It also acts as a plasticizer and softening agent.

In polymer and coating formulations requiring improved flexibility, it provides essential performance. As a solvent carrier, it dissolves oil-soluble actives and pigments in various dispersion systems. Decyl oleate is supplied as a clear to pale yellow liquid. It is available in cosmetic-grade and technical-grade specifications, with cosmetic grades typically conforming to standards such as Ph.Eur.

These purity benchmarks are relevant to personal care sourcing. Bulk supply is standard in drums and IBCs, with packaging options suited to both cosmetic and industrial procurement volumes.
