  • Applications

    Disodium 1-(2-(2-carboxyethoxy)ethyl)-1-(2-carboxyethyl)-4,5-dihydro-2-(15-methylhexadecyl)-1-H-imidazolium hydroxide (CAS 95046-33-6) is used primarily as a surfactant and emulsifier in cosmetics/personal care products, household cleaners, and related formulations; it also acts as a dispersant and stabilizer in coatings, inks, and polymer formulations; it can serve as an ionic-liquid based solvent or reaction medium, or as a phase-transfer catalyst in industrial synthesis; and as a chelating/sequestering agent for binding metal ions in cleaning formulations. Depending on local regulations and formulation limits, it may function as a specialty additive in these applications.
