Description

Amines, C12-18-Alkyldimethyl CAS NO 68391-04-8 is a high-purity, long-chain tertiary amine surfactant derived from natural fatty acids. This versatile chemical intermediate is valued for its excellent cationic properties, emulsification capabilities, and compatibility with various formulations. It is essential for manufacturers in the personal care, textile, agrochemical, and oilfield chemical industries seeking reliable, high-performance raw materials for their production processes.

Application

• Surfactant & Emulsifier: A key cationic component in fabric softeners, hair conditioners, and cosmetic creams, providing excellent softening and antistatic properties.
• Chemical Intermediate: Used in the synthesis of quaternary ammonium compounds (Quats), amine oxides, and betaines for enhanced biocidal and surfactant performance.
• Agrochemical Formulations: Acts as an effective emulsifier and adjuvant in herbicides, pesticides, and fungicides to improve spreading and adhesion on plant surfaces.
• Oilfield Chemicals: Serves as a corrosion inhibitor, biocide, and demulsifier agent in drilling fluids and production chemicals.
• Textile Processing: Utilized as a softening and lubricating agent for fibers and yarns to improve processability and final hand feel.
• Industrial Cleaning: Incorporated into acid-based cleaners and degreasers for its surfactant and corrosion-inhibiting properties.
