Description

n-(3-Aminopropyl)Stearamide is a high-purity, long-chain fatty acid amide derivative with a terminal primary amine group. This unique bifunctional structure makes it a valuable intermediate for synthesizing cationic surfactants, emulsifiers, and corrosion inhibitors. It is essential for manufacturers in the personal care, textile, and industrial chemical sectors seeking to develop products with enhanced conditioning, softening, or antistatic properties. Our supply of n-(3-Aminopropyl)Stearamide CAS NO 35567-30-7 ensures consistent quality and reliable performance for your formulation needs.

Application

• Cationic Surfactant Synthesis: A key raw material for producing quaternary ammonium compounds (quats) used in fabric softeners, hair conditioners, and antistatic agents.
• Personal Care Formulations: Serves as an intermediate for conditioning agents in shampoos, conditioners, and skin creams, providing excellent substantivity and softness.
• Textile Auxiliaries: Used in the manufacture of softening and lubricating agents for fibers and yarns, improving handle and processability.
• Corrosion Inhibition: Acts as a precursor for filming amines and other compounds that protect metal surfaces in industrial water systems and lubricants.
• Emulsifier & Dispersant: Functions as an intermediate for non-ionic or cationic emulsifiers in coatings, agrochemicals, and polymer emulsions.
• Biocide & Preservative Synergist: Can be used to formulate compounds with enhanced antimicrobial activity for industrial preservatives.
• Research & Development: A valuable building block in organic synthesis for pharmaceuticals and specialty chemicals.
