Description

Sodium Oleate CAS NO 16558-02-4 is the sodium salt of oleic acid, a key fatty acid derivative widely used as an emulsifier, surfactant, and stabilizer. Its amphiphilic nature makes it an essential component for creating stable mixtures of oil and water, which is critical for numerous industrial and manufacturing processes. This versatile chemical is indispensable for producers in the personal care, pharmaceutical, textile, and metalworking industries seeking reliable, high-quality raw materials.

Application

• Soap and Detergent Manufacturing: Acts as a primary surfactant and foaming agent in bar soaps, liquid soaps, and industrial cleaners.
• Cosmetics and Personal Care: Functions as an emulsifier and thickener in creams, lotions, and shaving products.
• Textile Processing: Serves as a lubricant and softening agent in fiber processing and fabric finishing.
• Metalworking Fluids: Used as an emulsifier and corrosion inhibitor in soluble oils and cutting fluids.
• Pharmaceuticals: Employed as an emulsifying agent in topical ointments and creams.
• Rubber and Polymer Industry: Acts as a processing aid and internal lubricant during compounding and vulcanization.
• Food Industry (as an indirect additive): Used in food-grade lubricants and release agents for processing equipment.
• Agricultural Formulations: Serves as an adjuvant and emulsifier in pesticide and herbicide concentrates.
