Description

Octadecylbis(2-Hydroxyethyl)Methylammonium Chloride is a quaternary ammonium compound valued for its cationic surfactant properties and excellent conditioning effects. This chemical is essential for formulators requiring stable, substantive agents that impart softness and antistatic characteristics. It is primarily needed by manufacturers in the personal care, textile processing, and industrial surfactant sectors.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic surfactant, providing excellent detangling, softness, and manageability to hair.
• Fabric Softeners: Used as a key active ingredient in liquid and dryer sheet formulations to soften fabrics and reduce static cling.
• Textile Auxiliaries: Serves as a softening and antistatic agent in yarn lubricants and fabric finishing processes.
• Industrial Biocides & Sanitizers: Utilized for its antimicrobial properties in formulations for hard surface disinfectants and algicides.
• Emulsion Stabilizer: Functions as a cationic emulsifier and stabilizer in various oil-in-water systems.
• Antistatic Coatings: Incorporated into coatings for plastics and synthetic fibers to dissipate static electricity.

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 lead to caking or degradation.
