Description

Hexadecyldimethylammonium Chloride is a high-purity quaternary ammonium compound (quat) widely recognized for its potent cationic surfactant properties. This material is essential for formulations requiring strong antimicrobial, antistatic, and conditioning effects. It serves as a critical raw material for manufacturers in the personal care, industrial biocides, textile, and water treatment sectors seeking reliable performance and supply chain consistency.

Application

• Biocide & Disinfectant Formulations: Acts as a key active ingredient in industrial, institutional, and agricultural disinfectants, sanitizers, and algicides due to its broad-spectrum antimicrobial efficacy.
• Personal Care & Cosmetics: Used as a conditioning agent and preservative in hair conditioners, creams, and lotions, providing softness and manageability.
• Textile & Fabric Softeners: Imparts a soft, antistatic finish to textiles and is a primary component in many commercial and household fabric softener concentrates.
• Water Treatment: Employed as a biocide and flocculant aid in cooling towers, pulp and paper processing, and oilfield water systems.
• Phase Transfer Catalyst: Facilitates reactions between reagents in immiscible solvents in specialty organic synthesis and pharmaceutical manufacturing.
• Emulsifier & Surfactant: Serves as an emulsifying agent in various industrial processes and formulations requiring cationic stabilization.

Quality Control

Our Hexadecyldimethylammonium Chloride 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 residue on ignition are provided to guarantee consistent quality and traceability for our global B2B clients.

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 product is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
