Abstract
The present invention provides novel fatty acid esters of alkoxylated isethionic acid and compositions comprising these compounds. Using the alkoxylated isethionates, stable, concentrated (greater 10% total active) solutions can be prepared (when isethionate is primary surfactant) which would not have been possible to prepare using nonalkoxylated isethionate.
