Industrial, Cosmetic, Pharmaceutical & Food Grade Stearic Acid CAS 57-11-4 Saturated Fatty Acid for Rubber Activator, PVC Stabilizer, Cosmetic Emollie

Stearic Acid (Alias: Octadecanoic Acid, CAS:57-11-4,EINECS:200-313-4, HS Code:3823110000), molecular formula C₁₈H₃₆O₂, molecular weight 284.48. It is white waxy flake or granular solid, insoluble in water, soluble in hot ethanol, ether and organic solvents. We supply industrial grade, cosmetic grade and food grade (Model:1801/1838/1842/1865). It has excellent lubrication, emulsification and dispersion properties, widely used in plastic, rubber, daily chemical, coating and food industries.

Applications
Plastic Industry (Core Application)
Internal & external lubricant, mold release agent and heat stabilizer for PVC plastic, polyolefin, engineering plastics. Improve plastic fluidity during extrusion/injection molding, prevent adhesion to molds, enhance surface gloss of finished plastic products.
Rubber Manufacturing Industry
Vulcanization activator and softener for natural rubber and synthetic rubber. Promote uniform dispersion of carbon black and fillers, accelerate vulcanization reaction, improve rubber flexibility and surface smoothness.
Cosmetic & Personal Care Industry
Basic raw material for cream, lotion, lipstick, soap and facial cleanser. Used as thickener, emulsifier and consistency regulator, improve cream texture, form protective film on skin surface.
Surfactant & Stearate Production
Core raw material to synthesize calcium/zinc/magnesium stearate, glyceryl monostearate and other nonionic surfactants, widely used in emulsifier, anti-caking agent production.
Coating, Ink & Polishing Agent
Flatting agent and dispersant for solvent-based paint and printing ink; raw material for polishing wax, crayons and waterproof coating, improve product scratch resistance.
Food & Feed Industry
Food grade acts as food processing aid, anti-caking agent and defoamer; feed grade serves as energy supplement and emulsifier additive for animal feed.
