Description

Quaternary Ammonium Compounds, Di-C12-20-Alkyldimethyl, Chlorides are a versatile class of cationic surfactants derived from natural fatty acids. These compounds are highly valued for their potent antimicrobial efficacy, excellent surface activity, and compatibility with a wide range of formulations. They are essential for manufacturers in the industrial, institutional, and personal care sectors seeking reliable and effective biocidal and conditioning agents.

Application

• Industrial & Institutional Disinfectants: Primary active ingredient in hard surface cleaners, sanitizers, and disinfectants for hospitals, food processing plants, and commercial facilities.
• Algaecides & Biocides: Used in water treatment systems, cooling towers, and recreational water to control microbial and algal growth.
• Fabric Softeners & Conditioners: Imparts softness and anti-static properties to textiles in laundry rinse cycles and industrial textile processing.
• Personal Care Products: Acts as a conditioning agent and preservative in hair conditioners, skin creams, and other cosmetic formulations.
• Oilfield Chemicals: Serves as a biocide and corrosion inhibitor in drilling muds, completion fluids, and production systems.
• Paper & Pulp Industry: Used as a debonding agent, retention aid, and biocide in paper manufacturing processes.
