Identification

Name:

Isethionic acid

Description

Isethionic acid (C2H6O4S) is a short chain alkane sulfonate containing hydroxy group, is a water soluble liquid used in the manufacture of mild, biodegradable and high foaming anionic surfactants which provides gentle cleansing and soft skin feel.; A colorless, syrupy, strongly acidic liquid that can form detergents with oleic acid. The Escherichia coli ssuEADCB gene cluster is required for the utilization of alkanesulfonates (such as isethionic acid) as sulfur sources, and is expressed under conditions of sulfate or cysteine starvation.
