Description

Fatty Acids, C16-18 And C18-Unsatd., Me Esters CAS NO 67762-38-3 is a defined mixture of methyl esters derived from palmitic, stearic, and unsaturated C18 fatty acids, primarily oleic acid. This product serves as a versatile and high-purity chemical intermediate, offering excellent solvency and reactivity for synthesis. It is essential for manufacturers in the personal care, lubricant, and oleochemical industries seeking consistent, high-quality raw materials for further transformation.

Application

• Surfactant & Detergent Intermediate: A key raw material for producing methyl ester sulfonates (MES), a high-performance, biodegradable anionic surfactant.
• Personal Care & Cosmetics: Used in the formulation of emollients, conditioners, and as a base for fatty alcohols in creams, lotions, and hair care products.
• Lubricant & Metalworking Fluids: Acts as a bio-based component and friction modifier in synthetic lubricants, greases, and cutting fluids.
• Plasticizer & Polymer Additive: Employed as a secondary plasticizer and internal lubricant in PVC and other polymer processing.
• Agrochemical Formulations: Functions as a solvent and carrier for pesticides and herbicides, enhancing their efficacy and penetration.
• Biodiesel Production: Serves as a model compound or a component in biodiesel research and quality control testing.
• Chemical Synthesis: A crucial starting material for manufacturing fatty acid amides, alkanolamides, and other oleochemical derivatives.
