Description

Hydrogenated Castor Oil CAS NO 8001-78-3 is a high-melting, waxy solid derived from the catalytic hydrogenation of natural castor oil, resulting in a saturated triglyceride with excellent stability and consistency. This process significantly enhances its oxidative stability and melting point, making it a superior, non-greasy structuring and thickening agent for demanding formulations. It is an essential ingredient for manufacturers in the cosmetics, pharmaceuticals, lubricants, and specialty chemicals industries seeking reliable performance and extended shelf life.

Application

• Cosmetics & Personal Care: Acts as a key consistency regulator, thickener, and stabilizer in stick formulations such as lipsticks, deodorants, and solid perfumes, providing structure and a smooth application feel.
• Pharmaceuticals: Used as a stiffening agent and controlled-release matrix in ointments, creams, and suppositories, offering excellent stability and compatibility.
• Lubricants & Greases: Serves as a high-performance additive and thickener in specialty lubricating greases, providing enhanced temperature resistance and water repellency.
• Coatings & Inks: Functions as a flatting and matting agent, as well as a rheology modifier, to improve the texture and application properties of coatings and printing inks.
• Plastics & Polymers: Employed as an internal and external lubricant and mold release agent in polymer processing to improve flow and prevent sticking.
• Food Industry (where compliant): Used as a release agent, coating agent, or texturizer in specific food-contact applications, subject to appropriate purity grades.
• Adhesives & Sealants: Provides thixotropic properties and body to prevent sagging and settling in adhesive and sealant formulations.
