Applications
1. For Soap And Cleansing Products: Sodium oleate (CAS 143-19-1) is a classic soap base and mild anionic surfactant, providing rich lather, cleansing and emulsifying performance for bar soap, industrial soap and cleansing formulations.
2. For Mineral Flotation Collectors: As a fatty acid salt collector, sodium oleate is widely used in froth flotation of non-sulfide minerals such as fluorite, apatite and iron ores, supporting efficient separation and recovery in mineral processing.
3. For Emulsifiers And Cosmetics: Sodium oleate acts as an emulsifier, thickener and foaming agent in cosmetics, skin care and personal care products, helping formulators stabilize oil-water emulsions and control viscosity.
4. For Industrial And Processing Applications: In textile processing, lubricant and cutting fluid formulations, sodium oleate works as a wetting, emulsifying and anti-corrosion surfactant, and supports rubber isolation and building waterproofing additives.
5. Reliable Supply For Global Industry: Supplied as high-purity powder, flakes and paste with consistent quality, sodium oleate gives soap, mining, cosmetic and industrial manufacturers a dependable fatty acid soap with stable supply, flexible packaging and professional technical support.
Quality Assurance
Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.
