Description

Octyl Stearate is a high-purity, synthetic ester derived from stearic acid and 2-ethylhexanol, known for its excellent emollient properties and chemical stability. This versatile compound is valued for its ability to act as a non-greasy lubricant and softening agent in a wide range of industrial and cosmetic formulations. It is an essential ingredient for manufacturers in the personal care, plastics, and textile industries seeking to enhance product texture and performance.

Application

• Cosmetics & Personal Care: A key emollient and skin-conditioning agent in creams, lotions, sunscreens, and makeup, providing a smooth, non-oily feel.
• Plastic & Rubber Industry: Functions as an internal and external lubricant and release agent in PVC, polystyrene, and synthetic rubber processing.
• Textile Processing: Used as a softening agent and lubricant for fibers and yarns to improve handle and reduce friction during weaving.
• Metalworking Fluids: Serves as a lubricity additive in synthetic and semi-synthetic cutting and drawing oils.
• Adhesives & Sealants: Acts as a plasticizer and processing aid to improve flexibility and application properties.
• Industrial Coatings & Inks: Employed as a flow and leveling agent to enhance finish quality and gloss.
