Description

C16-22-Alkyldimethyl Amines are a high-purity blend of tertiary amines characterized by their long alkyl chains. This product is a crucial intermediate for the synthesis of quaternary ammonium compounds, offering excellent surfactant properties and chemical versatility. It is essential for manufacturers in the personal care, textile, and industrial cleaning sectors seeking to produce high-performance cationic surfactants and biocides.

Application

• Primary intermediate for the synthesis of quaternary ammonium compounds (quats) used as fabric softeners and antistatic agents.
• Key raw material in the production of cationic surfactants for hair conditioners, cream rinses, and other personal care formulations.
• Precursor for biocides and disinfectants effective in industrial, institutional, and agricultural applications.
• Used as a corrosion inhibitor and emulsifier in various industrial processes and lubricant formulations.
• Employed in the manufacture of amine oxides, which are mild surfactants for shampoos and bubble baths.
• Acts as a flotation agent and collector in mineral processing operations.
• Intermediate for the production of betaines, used as amphoteric surfactants in cosmetic and detergent products.

Quality Control

Our C16-22-Alkyldimethyl Amines are manufactured under a strict quality management system. Each batch is analyzed to ensure consistent composition, purity, and performance characteristics. A comprehensive Certificate of Analysis (COA) detailing assay, amine value, and alkyl chain distribution is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) to prevent oxidation and absorption of moisture. Keep away from strong oxidizing agents.
