Description

Ethyldimethyl[3-[(1-Oxooctadecyl)Amino]Propyl]Ammonium Ethyl Sulphate is a quaternary ammonium compound with a long-chain fatty amide group, functioning as a cationic surfactant and conditioning agent. This unique structure provides excellent substantivity to surfaces and materials, offering both emulsifying and antistatic properties. It is a key ingredient for formulators in the personal care, textile, and industrial sectors seeking to enhance softness, manageability, and surface modification.

Application

• Hair Conditioners & Rinse-Off Products: Primary conditioning agent providing excellent detangling, softness, and manageability to hair.
• Skin Care & Creams: Used as an emulsifier and skin-conditioning agent in lotions and creams for a smooth, soft after-feel.
• Textile Softeners: Key component in fabric softener formulations, imparting a soft hand and reducing static cling on fibers.
• Industrial Surfactants: Acts as a cationic emulsifier, antistatic agent, and softener in various industrial processes and specialty chemical blends.
• Antistatic Formulations: Applied in products for plastics, synthetic fibers, and electronics to control static electricity.
• Agricultural Adjuvants: Used as a compatibility agent or deposition aid in pesticide and herbicide formulations.
