Description

Stearic Acid, Compound With 1-Aminopropan-2-Ol (1:1) is a specific organic salt formed from the reaction of stearic acid and 1-amino-2-propanol (monoisopropanolamine). This compound is valued for its dual functionality, combining the hydrophobic, lubricating, and emulsifying properties of a long-chain fatty acid with the hydrophilic, neutralizing, and reactive amine group of an alkanolamine. It serves as a versatile intermediate and functional additive, primarily for industrial formulators and chemical manufacturers seeking to modify surface properties, enhance stability, or create novel derivatives. Key industries that utilize this material include polymer production, personal care, and lubricant manufacturing.

Application

• Polymer Additive & Intermediate: Acts as a processing aid, internal lubricant, and anti-static agent in plastics (e.g., PVC, polyolefins). Also serves as a key intermediate for synthesizing specialized surfactants and emulsifiers.
• Personal Care & Cosmetics: Used as an opacifying agent, viscosity modifier, and emulsifier in creams, lotions, and hair care products, where it helps stabilize formulations and provides a smooth texture.
• Lubricant & Grease Formulation: Functions as a thickening agent and corrosion inhibitor in the production of metalworking fluids, industrial greases, and synthetic lubricants.
• Textile & Fiber Processing: Employed as a softener, lubricant, and anti-static agent in fiber spinning and fabric finishing to improve handle and processing performance.
• Coating & Ink Industry: Serves as a dispersing agent, flow modifier, and flatting agent in paints, coatings, and printing inks to enhance pigment dispersion and film properties.
• Rubber Compounding: Used as a processing aid and activator in rubber formulations to improve mold release, dispersion of fillers, and final product surface finish.
