Description

Quaternary Ammonium Compounds, Dimethylditallow Alkyl, Chlorides are a class of cationic surfactants derived from hydrogenated tallow fatty acids. These compounds are valued for their excellent fabric softening properties, antistatic effects, and biocidal activity, making them a versatile ingredient in industrial and consumer formulations. They are primarily utilized by manufacturers in the textile, personal care, and industrial cleaning sectors seeking effective and stable cationic agents.

Application

• Fabric Softeners & Conditioners: A primary component in liquid and dryer sheet fabric softeners, providing a soft hand feel and reducing static cling.
• Hair Conditioners & Cream Rinses: Used in personal care products to detangle hair, improve manageability, and impart shine.
• Industrial & Institutional (I&I) Cleaners: Acts as a surfactant and disinfectant in hard surface cleaners, floor polishes, and sanitizing solutions.
• Antistatic Agents: Applied in textile finishing and plastics processing to prevent the buildup of static electricity.
• Emulsifiers & Dispersants: Facilitates the formation and stabilization of oil-in-water emulsions in various chemical processes.
• Biocide & Sanitizer Formulations: Utilized for its antimicrobial properties in certain disinfectant and algicide products.

Quality Control

Our Quaternary Ammonium Compounds are manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance and meets specifications for key parameters such as active matter content, amine value, and pH. A Certificate of Analysis (COA) detailing the results is provided with every shipment to guarantee traceability and compliance with your requirements.

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); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality.
