Description

N,n-Dimethyl-n-[3-(Sulfooxy)Propyl]-1-Nonanaminium Hydroxide, Inner Salt is a specialized zwitterionic surfactant characterized by its unique sulfobetaine structure, offering excellent stability across a wide pH range and compatibility with various ionic systems. This compound is valued for its superior surface-active properties, providing effective wetting, emulsification, and foam control in demanding formulations. It is primarily utilized by manufacturers in the personal care, home care, and industrial cleaning sectors seeking high-performance, mild, and stable ingredients.

Application

• Personal Care Formulations: Used as a primary or co-surfactant in mild shampoos, body washes, facial cleansers, and baby care products due to its skin compatibility and low irritation potential.
• Home Care & Industrial Cleaners: Provides excellent wetting and soil suspension in hard surface cleaners, dishwashing liquids, and industrial degreasers, enhancing cleaning efficacy.
• Enhanced Oil Recovery (EOR): Acts as a key component in surfactant-polymer flooding formulations to reduce interfacial tension and improve oil displacement in reservoir engineering.
• Textile & Leather Processing: Serves as a leveling agent, softener, and dyeing assistant, improving process uniformity and final product quality.
• Paint & Coating Additives: Functions as a dispersant and wetting agent to stabilize pigments and fillers in aqueous coating systems.
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to improve spray droplet retention and active ingredient penetration on plant surfaces.
