Description

Cetyl Stearate is a high-purity, long-chain fatty acid ester derived from cetyl alcohol and stearic acid. This versatile compound serves as a highly effective emollient, lubricant, and viscosity modifier in a wide range of industrial and personal care formulations. It is an essential ingredient for manufacturers in the cosmetics, pharmaceuticals, plastics, and textile industries seeking to improve product texture, stability, and performance.

Application

• Cosmetics & Personal Care: Acts as a primary emollient and opacifying agent in creams, lotions, lipsticks, and makeup, providing a smooth, non-greasy feel and enhancing skin barrier function.
• Pharmaceuticals: Used as a lubricant and binder in tablet manufacturing, and as a base ingredient in topical ointments and creams for its soothing properties.
• Plastics & Polymers: Functions as an internal lubricant and mold release agent during the processing of PVC, polystyrene, and other polymers, improving flow and surface finish.
• Textile & Fiber: Serves as a softening agent and lubricant in yarn and fabric production, reducing fiber breakage and improving handle.
• Metalworking: Employed as a component in drawing compounds and cutting fluids, providing lubrication and corrosion protection.
• Candle & Wax Blending: Used to modify the melting point, hardness, and burn characteristics of candle waxes and industrial wax blends.
