Applications
1. For Soap And Detergent Manufacturing: Sodium stearate (CAS 822-16-2) is the classic sodium soap base, acting as a surfactant and emulsifier in bar soap production, delivering cleansing, lathering and structure to soap formulations.
2. For Cosmetics And Personal Care: As a vegetable-based thickener, gelling agent and emulsifier, sodium stearate is used in creams, lotions, deodorant sticks and emulsion formulations to build viscosity and stable product texture.
3. For Plastics And Rubber Processing: Sodium stearate serves as a lubricant, release agent and stabilizer in plastics and rubber processing, improving mold release and processing flow in PVC, PP and rubber compounding.
4. For Industrial And Textile Applications: The compound is used as an emulsifier, antistatic agent and waterproofing aid in textiles, and in lubricating greases, candles and polish formulations, offering manufacturers a versatile metal soap.
5. Reliable Supply For Global Industry: Supplied as high-purity white powder and flakes with consistent quality, sodium stearate gives soap, cosmetic, plastic and textile manufacturers a dependable stearate salt 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.
Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
