Cetyl Stearate

Overview

Cetyl Stearate (INCI: Cetyl Stearate, CAS: 1190-63-2) is a high molecular weight fatty acid ester, specifically synthesized through the esterification of cetyl alcohol and stearic acid. As a testament to its exceptional purity and versatility, it typically presents as white, waxy flakes or a fine powder, characterized by a mild, virtually imperceptible odor. This unique chemical structure, combining a long-chain fatty alcohol with a long-chain saturated fatty acid, imbues Cetyl Stearate with a powerful blend of functional properties that are highly sought after across numerous industrial sectors, particularly in personal care, pharmaceuticals, and specialty industrial formulations.

CanCastor's Cetyl Stearate is meticulously produced to meet stringent quality benchmarks, ensuring consistent performance as a robust emollient, opacifier, and rheology modifier. Its hydrophobic nature makes it an excellent film-former, providing a protective barrier in topical applications, while its waxy consistency contributes to formulation stability and viscosity building. Our commitment to transparent sourcing and rigorous quality control, including adherence to ISO 9001 standards and REACH compliance, ensures that our Cetyl Stearate is a reliable and superior ingredient for your most demanding applications. Clients trust CanCastor for a product that performs consistently batch after batch, backed by comprehensive technical support and global logistics capabilities.
