Description

Dodecylbenzyl Alkyl (70%C12, 30%C14) Dimethyl Ammonium Chloride is a high-purity quaternary ammonium compound (quat) widely recognized for its potent cationic surfactant and antimicrobial properties. This specific blend of C12 and C14 alkyl chains offers an optimal balance of solubility, surface activity, and biocidal efficacy for demanding industrial formulations. It is an essential raw material for manufacturers in the personal care, industrial cleaning, and water treatment sectors seeking reliable, high-performance active ingredients.

Application

• Industrial & Institutional (I&I) Disinfectants & Sanitizers: A key active ingredient in formulations for hard surface disinfectants, food contact surface sanitizers, and algaecides for swimming pools and cooling towers.
• Personal Care & Cosmetics: Used as a conditioning agent and preservative booster in hair conditioners, skin creams, and other leave-on or rinse-off products.
• Fabric Softeners & Textile Auxiliaries: Provides excellent softening and antistatic properties in household and commercial fabric softener concentrates.
• Oilfield & Industrial Water Treatment: Functions as a biocide and corrosion inhibitor in drilling muds, fracturing fluids, and industrial process water systems.
• Agricultural Adjuvants: Employed as a surfactant and emulsifier in pesticide and herbicide formulations to enhance spreading and adhesion on plant surfaces.
• Household Cleaners: Incorporated into all-purpose cleaners, bathroom cleaners, and floor care products for its cleaning and disinfecting capabilities.

Quality Control

Our Dodecylbenzyl Alkyl Dimethyl Ammonium Chloride is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance that meets or exceeds industry standards. A comprehensive Certificate of Analysis (COA) detailing assay, alkyl chain distribution, and key impurity profiles is available for each shipment upon request.

Storage

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