Description

Trimethylstearylammonium Chloride is a high-purity quaternary ammonium salt (quat) widely recognized for its cationic surfactant properties. This compound is essential for delivering superior conditioning, emulsification, and antimicrobial efficacy in demanding industrial and personal care formulations. It is a critical raw material for manufacturers in the personal care, textile, and specialty chemical industries seeking reliable performance and consistent quality.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic surfactant, providing excellent detangling, softness, and manageability to hair.
• Fabric Softeners: Imparts a soft, fluffy hand feel to textiles and reduces static cling.
• Antistatic Agents: Used in plastics, textiles, and industrial processes to dissipate static electricity.
• Emulsifiers & Dispersants: Stabilizes oil-in-water emulsions and aids in the dispersion of pigments and other solids.
• Biocides & Sanitizers: Provides antimicrobial activity in disinfectant formulations for industrial and institutional use.
• Phase Transfer Catalysis: Facilitates reactions between reagents in immiscible phases in organic synthesis.

Quality Control

Our Trimethylstearylammonium Chloride is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance. A Certificate of Analysis (COA) documenting key parameters such as assay, moisture content, and residue on ignition is provided with each shipment to guarantee traceability and compliance.

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 to prevent absorption of atmospheric moisture.
