Description

Isooctadecyl Stearate is a high-purity, synthetic ester derived from stearic acid and isooctadecanol. This compound serves as a versatile and effective emollient, lubricant, and viscosity modifier in demanding formulations. It is essential for manufacturers in the personal care, cosmetics, and specialty lubricants industries seeking stable, non-greasy, and high-performance ingredients. Its excellent oxidative stability and compatibility with a wide range of materials make it a valuable asset for product developers.

Application

• Personal Care & Cosmetics: Acts as a premium emollient and skin-conditioning agent in creams, lotions, sunscreens, and makeup, providing a smooth, non-greasy feel.
• Hair Care Products: Used in conditioners, serums, and styling products to impart shine, reduce frizz, and improve combability.
• Industrial Lubricants & Greases: Functions as a synthetic base oil or additive to enhance lubricity, reduce friction, and improve low-temperature performance.
• Plastic & Polymer Processing: Employed as an internal or external lubricant and release agent to improve flow properties and mold release in polymers like PVC and engineering plastics.
• Textile & Fiber Treatment: Serves as a softening agent and lubricant for synthetic fibers and yarns to improve processing and hand feel.
• Metalworking Fluids: Incorporated as a lubricity additive in cutting oils and drawing compounds to protect tools and improve surface finish.
