Description

Ethylbis(Hydroxyethyl)(Octadecyl)Ammonium Ethyl Sulphate is a quaternary ammonium compound (quat) valued for its potent cationic surfactant properties. This chemical is essential for formulating high-performance products that require effective surface modification, emulsification, and antimicrobial activity. It is primarily sought by manufacturers in the personal care, textile processing, and industrial cleaning sectors for its reliable performance and compatibility.

Application

• Fabric Softeners & Conditioners: A key cationic agent for imparting softness, antistatic properties, and a pleasant feel to textiles.
• Hair Conditioners & Cream Rinses: Used to improve hair manageability, reduce static, and enhance combability in personal care formulations.
• Industrial & Institutional (I&I) Cleaners: Acts as a surfactant and disinfectant aid in hard surface cleaners, floor polishes, and sanitizing solutions.
• Emulsifier & Antistatic Agent: Facilitates the formation and stability of oil-in-water emulsions and prevents static buildup in plastics and synthetic fibers.
• Biocide & Preservative Systems: Incorporated as an active ingredient or potentiator in formulations requiring microbiological control.
• Paper & Pulp Processing: Utilized as a softener, debonding agent, or retention aid in specialty paper manufacturing.
• Metal Working Fluids: Serves as a corrosion inhibitor and emulsifying component in coolants and cutting fluids.
• Agricultural Adjuvants: Enhances the spreading and adhesion of pesticides and herbicides on plant surfaces.
