Description

(Z)-9-Octadecenoic Acid 2-(1-Oxooctadecyl)Oxyethyl Ester is a high-purity oleochemical derivative, specifically a diester of oleic acid, valued for its excellent emollient and lubricating properties. This compound is engineered to provide superior performance as a non-ionic surfactant and a versatile chemical intermediate in advanced formulations. It is essential for manufacturers in the personal care, cosmetics, and specialty lubricants industries seeking stable, high-quality raw materials.

Application

• Personal Care & Cosmetics: Acts as a premium emollient, skin-conditioning agent, and opacifier in creams, lotions, and makeup products.
• Lubricants & Release Agents: Serves as a key component in synthetic lubricants, mold release agents, and textile fiber lubricants due to its low volatility and stability.
• Polymer & Plastic Additives: Used as an internal or external lubricant and plasticizer in PVC and other polymer processing to improve flow and surface finish.
• Chemical Synthesis: Functions as a crucial intermediate for synthesizing more complex esters, surfactants, and specialty chemicals.
• Textile Processing: Employed as a softening agent and lubricant in fiber production and fabric finishing.
• Industrial Coatings: Enhances the flow, leveling, and gloss properties of paints, inks, and coating formulations.
