Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.,.Alpha.'-[[(Carboxymethyl)Octadecyliminio]Di-2,1-Ethanediyl]Bis-.Omega.-Hydroxy-, Inner Salt is a high-purity, amphoteric surfactant belonging to the betaine class, known for its excellent mildness, foam stability, and compatibility with other ionic species. This compound is engineered to deliver superior performance as a viscosity modifier and conditioning agent, offering exceptional stability across a wide pH range. It is a critical ingredient for formulators in the personal care, home care, and industrial cleaning sectors seeking to enhance product texture, mildness, and overall efficacy.

Application

• Personal Care Formulations: Primary use as a mild surfactant and viscosity booster in shampoos, body washes, facial cleansers, and baby care products.
• Home Care Products: Key component in liquid dish soaps, hard surface cleaners, and all-purpose cleaners for its foam stability and compatibility with anionic surfactants.
• Industrial & Institutional (I&I) Cleaning: Used in formulations for vehicle wash, food processing plant cleaners, and dairy detergents due to its hard water tolerance and stability.
• Cosmetic Thickening: Acts as an efficient thickener and emulsifier in lotions, creams, and conditioning treatments, improving sensory feel and product stability.
• Oilfield Chemicals: Employed in drilling muds and completion fluids as a foaming agent and viscosity control additive.
• Textile & Leather Processing: Functions as a softener, leveling agent, and antistatic agent in dyeing and finishing processes.
