  • Applications

    N-(2-Hydroxyethyl)-N-(2-hydroxytetradecyl)beta-alanine (CAS 70521-71-0) is predominantly evaluated as an amphiphilic building block and surfactant; in cosmetics and personal care formulations it can act as an emulsifier and solubilizer for oils and actives; in household and cleaning products it functions as a mild surfactant and compatibility enhancer; in industrial manufacturing, coatings and inks, it serves as a dispersant or stabilizer, helping to control surface tension and rheology; as an intermediate for synthesizing amphiphilic polymers or polymeric surfactants for plastics and coatings, it may be incorporated as a specialty additive.
