Sodium 2-hydroxyethyl sulfonate (also: sodium isethionate) is the sodium salt of 2-hydroxyethane sulfonic acid (isethionic acid), it is used as hydrophilic head group in washing-active surfactants, known as isethionates (acyloxyethanesulfonates) due to its strong polarity and resistance to multivalent ions. It is being studied as high production volume chemical in the \"High Production Volume (HPV) Chemical Challenge Program\" of the US Environmental Protection Ministry EPA.
