Description

Ethanaminium, N-(2-hydroxyethyl)-N-[2-[(2-hydroxyethyl)[2-[(2-hydroxyethyl)[2-[(1-oxohexadecyl)oxy]ethyl]amino]ethyl]amino]ethyl]-2-[(2-hydroxyethyl)(1-oxohexadecyl)amino]-N-methyl-, methyl sulfate (salt) is a high-purity, quaternary ammonium compound valued for its exceptional surface-active properties. This specialty chemical is engineered to deliver superior performance as a cationic surfactant and emulsifier in demanding formulations. It is a critical component for manufacturers in the personal care, textile, and industrial cleaning sectors who require reliable, high-performance ingredients for stable emulsions and effective surface modification.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic conditioning agent, providing excellent detangling, softness, and manageability to hair.
• Skin Care Creams & Lotions: Functions as a powerful emulsifier and softener, enhancing the texture and stability of oil-in-water emulsions.
• Textile Softeners & Antistatic Agents: Imparts a soft, smooth hand-feel to fabrics and reduces static cling during processing and use.
• Industrial & Institutional Cleaners: Serves as a surfactant and emulsifier in hard-surface cleaners, where it aids in soil removal and provides surface substantivity.
• Fabric Dyeing & Printing Auxiliaries: Used as a leveling agent and dye fixative to improve color uniformity and fastness.
• Agricultural Adjuvants: Enhances the spreading and adhesion of pesticides and herbicides on plant surfaces.
• Paper & Pulp Chemicals: Employed as a softener, debonding agent, or retention aid in specific papermaking processes.
• Bitumen Emulsifiers: Facilitates the formation of stable cationic bitumen emulsions for road construction and maintenance.
