Description

1-Dodecanaminium, n-(Carboxymethyl)-N,n-Bis(2-Hydroxyethyl)-, Inner Salt is a high-purity amphoteric surfactant and betaine derivative, valued for its excellent mildness, foam stability, and compatibility with other ionic species. This compound is essential for formulators requiring high-performance, low-irritation ingredients with superior viscosity-building and conditioning properties. It is primarily sought by manufacturers in the personal care, home care, and industrial cleaning sectors for its versatile functionality.

Application

• Personal Care Formulations: A key mild surfactant and foam booster in shampoos, body washes, facial cleansers, and baby care products.
• Home & Institutional Cleaning: Used in dishwashing liquids, hard surface cleaners, and all-purpose cleaners for its grease-cutting ability and compatibility with anionic surfactants.
• Industrial & Metalworking Fluids: Acts as a corrosion inhibitor and emulsifier in cutting oils, lubricants, and degreasers.
• Textile & Leather Processing: Functions as a softener, leveling agent, and dyeing assistant due to its amphoteric nature.
• Oilfield Chemicals: Employed in drilling muds and enhanced oil recovery formulations as a viscosity modifier and stabilizer.
• Agricultural Adjuvants: Enhances the spreading and sticking of pesticides and herbicides on plant surfaces.
