Description

Dodecyldimethylammonium Acetate is a quaternary ammonium compound (quat) that functions as a cationic surfactant and antimicrobial agent. Its value lies in its dual functionality, providing both surface activity and biocidal properties in a single molecule. This makes it a critical raw material for formulators in the personal care, industrial cleaning, and water treatment industries seeking effective and stable active ingredients.

Application

• Disinfectant & Sanitizer Formulations: As an active antimicrobial ingredient in hard surface cleaners, hospital-grade disinfectants, and food processing sanitizers.
• Personal Care Products: Used as a conditioning agent and preservative in hair conditioners, skin creams, and other cosmetic formulations.
• Industrial & Institutional (I&I) Cleaning: A key component in industrial detergents, laundry sanitizers, and fabric softeners for its surfactant and antimicrobial action.
• Water Treatment: Employed as a biocide and algicide in cooling towers, swimming pools, and process water systems.
• Oilfield Chemicals: Functions as a bactericide in drilling muds and fracturing fluids to control sulfate-reducing bacteria (SRB).
• Textile & Leather Processing: Acts as a softener, antistatic agent, and antimicrobial finish for fibers and hides.
• Agricultural Adjuvants: Used as a surfactant and emulsifier in pesticide and herbicide formulations to enhance efficacy.

Quality Control

Our Dodecyldimethylammonium Acetate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and microbiological efficacy are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents and strong acids. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent absorption of atmospheric moisture.
