Description

3-Chloro-2-Hydroxypropyltrimethyl Ammonium Chloride is a versatile and highly reactive cationic etherifying agent, primarily used to introduce a permanent positive charge onto various substrates. This compound is critical for modifying the physical and chemical properties of materials, enhancing performance in demanding industrial applications. It is an essential intermediate for manufacturers in the water treatment, paper, textile, and personal care industries seeking to impart cationic functionality for improved process efficiency and product performance.

Application

• Cationic Starch Production: As a key reagent for the quaternization of starch, creating cationic starch used as a wet-end additive and retention aid in papermaking.
• Flocculant and Coagulant Aid: Used in the synthesis of cationic polyacrylamides and other polymers for water and wastewater treatment to remove suspended solids and clarify process water.
• Textile Chemical Auxiliaries: Employed in the manufacture of cationic softeners, dye-fixing agents, and antistatic agents for textiles and fibers.
• Personal Care Ingredients: Serves as a precursor for cationic conditioning agents in hair care products (e.g., conditioners) and skin care formulations.
• Oilfield Chemicals: Used in the synthesis of clay stabilizers and shale inhibitors for drilling fluids in the oil and gas industry.
• Surface Modification: For the cationic modification of cellulose, guar gum, and other natural polymers to alter charge characteristics and improve binding or adsorption properties.

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); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and reactivity. Keep away from strong bases and oxidizing agents.
