Description

Aluminum Stearate is a versatile metallic soap widely used as a gelling agent, thickener, and stabilizer. Its primary value lies in its ability to impart thixotropic properties and water repellency to various formulations. This compound is essential for manufacturers in the coatings, plastics, cosmetics, and pharmaceutical industries seeking to control viscosity and improve product texture.

Application

• Coatings & Paints: Acts as a flatting and suspending agent, preventing pigment settling and improving brushability.
• Plastics & Polymers: Used as an acid scavenger, lubricant, and release agent in PVC and other polymer processing.
• Cosmetics & Personal Care: Functions as an opacifier, viscosity modifier, and emulsion stabilizer in creams, lotions, and makeup.
• Pharmaceuticals: Serves as a tablet and capsule lubricant and a gelling agent in topical preparations.
• Greases & Lubricants: Employed as a thickener to produce consistent, water-resistant lubricating greases.
• Construction Materials: Imparts hydrophobic properties to cement, concrete, and waterproofing compounds.
• Pyrotechnics: Used as a fuel and burning rate modifier in fireworks and other pyrotechnic compositions.
