3. Applications
- Food Industry: Used as emulsifier, stabilizer, and texturizer in baked goods, confectionery, margarine, and dairy products; improves texture, prevents oil separation, and extends shelf life.
- Cosmetics Industry: Acts as emollient, thickener, and stabilizer in creams, lotions, and lipsticks; enhances skin moisturization and product spreadability.
- Pharmaceutical Industry: Serves as excipient in tablet coatings and lipid-based drug delivery systems; improves drug solubility and bioavailability.
- Plastic & Rubber Industry: Functions as internal lubricant and mold release agent for PVC, PP, and PE plastics; reduces processing friction and improves product surface finish.
4. Storage and Handling
- Storage Conditions: Store in a cool, dry, well-ventilated warehouse at 15–25 °C. Protect from direct sunlight, heat sources, and moisture. Seal the package tightly to prevent caking and contamination.
- Handling Precautions: Wear protective gloves and goggles during operation. Avoid inhalation of dust and contact with eyes and skin. In case of accidental contact, rinse the affected area with plenty of water immediately.
5. Stability and Reactivity
- Stability: Chemically stable under normal storage and use conditions. Hydrolyzes in acidic or alkaline environments at high temperatures, producing stearic acid and glycerol.
