Description

Stearate CAS NO 646-29-7 is a versatile metallic salt of stearic acid, commonly known as aluminum tristearate. This compound is valued for its role as a thickening agent, gellant, and stabilizer in various industrial formulations. It is essential for manufacturers in the cosmetics, paints and coatings, plastics, and pharmaceutical industries seeking to modify rheology and improve product texture and stability.

Application

• Cosmetics & Personal Care: Acts as a viscosity modifier and opacifying agent in creams, lotions, deodorants, and makeup products.
• Paints, Inks & Coatings: Functions as a flatting and suspending agent to control gloss and prevent pigment settling.
• Plastics & Polymers: Serves as an acid scavenger and lubricant in PVC and other polymer processing.
• Pharmaceuticals: Used as a tablet and capsule lubricant and as a gelling agent in topical preparations.
• Greases & Lubricants: Employed as a thickening agent to produce consistent, high-temperature stable greases.
• Construction Materials: Utilized as a waterproofing agent and rheology modifier in cement-based products.
