Description

Isodecyl Hydroxystearate is a high-performance, non-ionic ester derived from hydroxystearic acid and isodecyl alcohol. This specialty chemical serves as a versatile emollient, lubricant, and coupling agent, prized for its excellent skin feel, thermal stability, and compatibility with a wide range of organic materials. It is essential for formulators in the personal care, cosmetics, and industrial lubricant sectors seeking to enhance product performance and sensory characteristics.

Application

• Personal Care & Cosmetics: Acts as a premium emollient and skin-conditioning agent in creams, lotions, sunscreens, and lipsticks, providing a non-greasy, silky feel.
• Industrial Lubricants & Greases: Functions as a synthetic base oil or additive, offering good lubricity, oxidation resistance, and low-temperature fluidity.
• Plastic & Polymer Additives: Used as an internal or external lubricant and processing aid in PVC and other polymers to improve flow and mold release.
• Metalworking Fluids: Serves as a lubricity additive and corrosion inhibitor in cutting, grinding, and drawing oils.
• Textile Auxiliaries: Employed as a softening agent and lubricant for fibers and yarns to reduce friction and improve handle.
• Adhesives & Sealants: Acts as a plasticizer and rheology modifier to enhance flexibility, adhesion, and application properties.
