Description

Ammonium 2-Hydroxyethanesulphonate is the ammonium salt of isethionic acid, a versatile organosulfur compound. This chemical is valued for its surfactant properties and its role as a key intermediate in the synthesis of specialty chemicals. It is primarily sought by manufacturers in the personal care, detergent, and pharmaceutical industries for formulating mild cleansers, creating amphoteric surfactants, and developing active pharmaceutical ingredients.

Application

• Surfactant Intermediate: A crucial building block for the synthesis of mild, amphoteric, and anionic surfactants, particularly taurates and isethionates.
• Personal Care Formulations: Used in the production of ultra-mild shampoos, body washes, facial cleansers, and baby care products due to its excellent skin compatibility.
• Detergent Industry: Serves as a precursor for high-performance, biodegradable detergents and cleaning agents.
• Pharmaceutical Synthesis: Acts as an intermediate in the manufacture of certain active pharmaceutical ingredients (APIs) and drug delivery agents.
• Chemical Synthesis: Employed as a buffering agent and a source of the sulphoethyl group in various organic synthesis pathways.
• Industrial Cleaning: Found in specialized industrial and institutional cleaning formulations requiring effective yet gentle surfactants.
