Hydrogenated Castor Oil (Castor Wax)

Overview

Hydrogenated Castor Oil (HCO), universally recognized as Castor Wax (INCI: Hydrogenated Castor Oil; CAS No. 8001-78-3), stands as a versatile, high-performance oleochemical derivative essential across numerous industrial and specialty applications. Produced through the controlled hydrogenation of refined castor oil, this meticulous process fully saturates the fatty acid chains, transforming the liquid oil into a hard, brittle, high-melting point wax. This transformation significantly enhances its oxidative stability, improves heat resistance, and provides superior hardness and insolubility compared to natural castor oil, making it an invaluable ingredient where durability and robust performance are critical. As a global leader in castor oil derivatives, CanCastor is committed to supplying HCO that meets the most stringent quality and regulatory benchmarks.

Our Hydrogenated Castor Oil is an exemplary product of advanced oleochemistry, offering exceptional functional benefits across a broad spectrum of industries, from pharmaceuticals and food to cosmetics and industrial lubricants. Its unique molecular structure, primarily composed of 12-hydroxystearic acid (after hydrogenation of ricinoleic acid), imparts distinctive properties such such as excellent oil binding capacity, superior barrier formation, and enhanced structural integrity. This makes HCO an indispensable component for formulators seeking to improve texture, extend shelf life, and boost the performance of their end products. CanCastor leverages decades of expertise in oleochemical processing, ensuring that our HCO consistently adheres to rigorous quality certifications like ISO 9001 and meets pharmacopoeial standards (USP, BP), demonstrating our unwavering trustworthiness and authoritativeness as a premium supplier.
