Description

Fatty Acids, Soya, Me Esters CAS NO 68919-53-9 are a refined derivative of soybean oil, consisting of the methyl esters of its constituent fatty acids. This product matters as a versatile, renewable, and biodegradable chemical intermediate with excellent solvency and reactivity. It is primarily needed by manufacturers in the personal care, lubricants, and oleochemical industries seeking sustainable raw materials for synthesis and formulation.

Application

• Surfactant & Detergent Precursor: A key intermediate for the production of fatty alcohol sulfates, ethoxylates, and other non-ionic surfactants used in liquid soaps, shampoos, and industrial cleaners.
• Personal Care & Cosmetics: Acts as an emollient, solvent, and carrier oil in creams, lotions, and hair care products, valued for its skin-friendly properties.
• Bio-lubricants & Metalworking Fluids: Serves as a base stock or additive in formulating environmentally acceptable lubricants, cutting fluids, and rust preventatives.
• Plasticizer & Polymer Additive: Used to improve the flexibility and processing of polymers like PVC and as a reactive diluent in various resin systems.
• Agrochemical Formulations: Functions as a co-solvent, penetrant, and carrier in pesticides, herbicides, and adjuvants.
• Oleochemical Synthesis: A crucial starting material for producing fatty alcohols, amides, and other derivatives via transesterification, hydrogenation, or amidation reactions.
