Sodium oleate

Sodium oleate (CAS 143-19-1), also known commercially as Eunatrol, is the sodium salt of oleic acid and functions as a fatty acid soap with emulsifying, dispersing, and cleaning properties across multiple industrial sectors.

It bridges the gap between oleochemical raw materials and functional surfactant applications, making it a practical choice for formulators working across both industrial and personal care markets.

In metalworking and lubrication, this compound acts as a boundary lubricant and rust inhibitor in cutting fluids and metal processing emulsions. Personal care and cosmetics formulators use it as an emulsifier and cleansing agent.

It is frequently found in bar soaps, creams, and skin conditioning products. Textile and leather processing operations rely on it for fiber lubrication, softening baths, and degreasing hides during preparation.

In food-contact and industrial cleaning formulations, it contributes foam control and emulsification where biodegradable surfactant options are preferred. The material is supplied as a white to off-white powder or as a paste.

Technical and food-grade specifications are the most commonly stocked forms, with purity levels typically ranging from 90% to 99%. These grades often meet FCC or USP standards depending on the application.

Buyers should confirm oleic acid chain profile and moisture content when evaluating grades for sensitive formulation work. This ensures the material meets the specific requirements for stability and performance in the final product.
