APPLICATIONS
|
Isethionic acid,
short chain alkane sulfonate containing hydroxy group,
is a water soluble, strongly acidic liquid used in the manufacture of
mild, biodegradable and high foaming anionic surfactants
which provides gentle cleansing and soft skin
feel. Isethionic acid
is the trivial name for 2-hydroxyethanesulfonic acid
which is the parent compound of sodium isethionate.
Sodium isethionate is prepared by the reaction of ethylene oxide with sodium bisulfite
solution. It is used as a key raw material in the manufacturing of Igepon type surfactants
which are ethanesulfonated detergent bars. Igepon type surfactants
include:
