Description

Stearic Acid, Compound With 1,1',1''-Nitrilotri(Propan-2-Ol) (1:1) is a specialized chemical complex formed between stearic acid and triisopropanolamine. This compound is engineered to offer enhanced performance characteristics, combining the lubricating and hydrophobic properties of a fatty acid with the emulsifying and neutralizing capabilities of an alkanolamine. It serves as a critical functional additive and intermediate in the production of high-performance industrial formulations, particularly where controlled release, improved stability, or specific surface interactions are required. Key industries that utilize this material include polymer manufacturing, personal care, and advanced lubricant systems.

Application

• Polymer Additive: Acts as an internal and external lubricant, acid scavenger, and anti-static agent in PVC, polyolefins, and engineering plastics processing.
• Personal Care & Cosmetics: Used as a viscosity modifier, opacifier, and emulsifying agent in creams, lotions, and stick formulations such as deodorants.
• Metalworking Fluids: Functions as a corrosion inhibitor and lubricity additive in synthetic and semi-synthetic cutting and grinding fluids.
• Textile Auxiliaries: Serves as a softener and lubricant in fiber processing and finishing to improve handle and reduce friction.
• Rubber Industry: Employed as a processing aid and activator in the vulcanization of various rubber compounds.
• Coatings & Inks: Imparts improved flow, leveling, and pigment dispersion in specific coating systems.
• Adhesives & Sealants: Used as a tackifier modifier and rheology control agent.
• Chemical Intermediate: For the synthesis of more complex esters, amides, and quaternary ammonium compounds.
