Isethionic Acid, chemically identified as 2-Hydroxyethanesulfonic acid, is a bifunctional short-chain organic sulfonic acid containing both a hydroxyl and a sulfonic acid group. Frequently referenced in industrial synthesis as 2-Hydroxy-1-ethanesulfonic acid or Hydroxyethyl sulfonic acid, this compound serves as a critical intermediate in the manufacturing of biodegradable surfactants (such as sodium cocoyl isethionate) and as a starting material for taurine production. We offer bulk supply of this chemical intermediate with competitive factory pricing, customized specifications for concentration levels, and complete regulatory documentation including MSDS, TDS, COA.

FAQ - Technical & Supply Chain
-
Q:
How is the identity of Isethionic Acid verified for industrial formulation?
A: Consistency is confirmed through the presence of both a terminal hydroxyl group and a sulfonic acid group on a two-carbon chain (C2H6O4S). In industrial procurement, this is cross-verified against CAS 107-36-8 and its specific acidity and solubility profiles to ensure it is not confused with simple ethoxylated sulfonates or other hydroxy-alkane acids. -
Q:
Is Isethionic Acid intended for direct use in consumer products or industrial synthesis?
A: This material is intended for use as an industrial raw material rather than a finished product. It is typically applied in the chemical synthesis of isethionate-based surfactants, where it undergoes reaction with fatty acids or fatty acid chlorides within controlled manufacturing environments.
