Description

Quaternary Ammonium Compounds, Di-C16-18-Alkyldimethyl, Chlorides are a high-purity class of cationic surfactants, primarily valued for their potent antimicrobial and antistatic properties. This compound is essential for formulators requiring a reliable, broad-spectrum active ingredient with excellent compatibility in various matrices. It is a critical raw material for manufacturers in the personal care, industrial cleaning, and water treatment sectors seeking effective and stable performance.

Application

• Disinfectant & Sanitizer Formulations: A key active ingredient in hospital-grade disinfectants, surface cleaners, and food contact sanitizers due to its bactericidal and virucidal efficacy.
• Personal Care & Cosmetics: Used as a conditioning agent and preservative in hair conditioners, skin creams, and lotions for its antistatic and emulsifying properties.
• Industrial & Institutional (I&I) Cleaning: Employed in floor cleaners, fabric softeners, and dairy/brewery cleaners for its superior cleaning and sanitizing power.
• Water Treatment: Acts as a biocide and algicide in cooling towers, swimming pools, and industrial water systems to control microbial growth.
• Textile & Leather Processing: Serves as a softener, antistatic agent, and dyeing auxiliary to improve fabric handle and processing.
• Oilfield Chemicals: Utilized as a corrosion inhibitor and biocide in drilling fluids and production systems.

Quality Control

Our Quaternary Ammonium Compounds, Di-C16-18-Alkyldimethyl, Chlorides are manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance that meets or exceeds industry standards. Certificates of Analysis (COA) detailing key parameters such as active matter content, amine value, and moisture are available upon request.

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). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
