Description

1-Ethyl-2-Heptadecyl-4,5-Dihydro-1-(2-Hydroxyethyl)-1H-Imidazolium Ethyl Sulphate is a high-purity, long-chain imidazolium-based ionic liquid with unique surfactant properties. This compound is valued for its dual functionality as a cationic surfactant and a phase-transfer catalyst, enabling superior performance in complex chemical processes. It is primarily sought by manufacturers in the textile, personal care, and specialty chemical industries for its efficacy as a softener, emulsifier, and reaction medium.

Application

• Textile Softening Agent: Imparts a durable, soft hand feel to natural and synthetic fibers, particularly in fabric conditioners and finishing treatments.
• Hair Conditioner & Cosmetic Formulations: Acts as a cationic conditioning agent in shampoos, conditioners, and skin creams, providing excellent detangling and smoothness.
• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, crucial in organic synthesis for alkylation, esterification, and polymerization.
• Antistatic Agent: Used in plastics, fibers, and electronics manufacturing to dissipate static charge and prevent dust accumulation.
• Emulsifier & Dispersant: Stabilizes oil-in-water emulsions and aids in the dispersion of pigments and fillers in coatings and agrochemical formulations.
• Corrosion Inhibitor: Provides protective films on metal surfaces in industrial cooling systems and acid cleaning solutions.
• Biocide & Preservative Enhancer: Used in combination with other antimicrobial agents to improve efficacy in disinfectants and preservative systems.
• Research & Development: Serves as a specialty ionic liquid solvent or reagent in academic and industrial R&D for green chemistry applications.
