Description

Glycerol Tristearate is a high-purity, fully saturated triglyceride derived from stearic acid. This compound serves as a critical emulsifier, thickener, and consistency agent in numerous industrial and consumer formulations. It is essential for manufacturers in the cosmetics, personal care, food, and plastics industries seeking to stabilize emulsions, modify texture, and control crystallization processes.

Application

• Cosmetics & Personal Care: Acts as a key opacifying agent, viscosity modifier, and emollient in creams, lotions, soaps, and makeup products.
• Food Industry: Used as a food additive (E478) for emulsification, stabilization, and as a release agent in baked goods, confectionery, and margarine.
• Plastics & Polymers: Functions as an internal lubricant and anti-static agent in PVC and other polymer processing to improve flow and mold release.
• Pharmaceuticals: Employed as a tablet and capsule lubricant and as a base for sustained-release formulations.
• Candles & Waxes: Used to harden and raise the melting point of candle waxes and other wax blends.
• Textile & Leather: Serves as a softening and finishing agent in fabric and leather treatment processes.
• Metalworking: Acts as a component in drawing and rolling lubricants for metal forming operations.
