Description

1-(Carboxylatomethyl)-4,5-Dihydro-1-(2-Hydroxyethyl)-2-Undecyl-1-Imidazolium is a specialized imidazolium-based zwitterionic surfactant and ionic liquid. This compound matters for its unique combination of a cationic imidazolium head group and an anionic carboxylate functionality, offering excellent surface activity, solubility control, and compatibility in demanding formulations. It is primarily needed by manufacturers in the personal care, textile processing, and specialty chemical synthesis industries seeking high-performance, multifunctional ingredients.

Application

• Personal Care Formulations: Acts as a mild surfactant, emulsifier, and conditioning agent in shampoos, body washes, and skin creams.
• Textile Auxiliaries: Used as a softener, antistatic agent, and dyeing assistant for synthetic and natural fibers.
• Corrosion Inhibition: Serves as an effective additive in cooling water systems and metal treatment fluids.
• Pharmaceutical Intermediates: Utilized in the synthesis of active pharmaceutical ingredients (APIs) and drug delivery systems.
• Enhanced Oil Recovery (EOR): Functions as a surfactant to reduce interfacial tension in oilfield applications.
• Polymer Modification: Employed as a monomer or additive to impart ionic character and modify the properties of polymers.
• Analytical Chemistry: Can be used as a component in mobile phases for chromatographic separations.
• Catalysis: Acts as a solvent or ligand in various catalytic reactions due to its ionic liquid nature.
