IUPAC NAME: sodium;2-hydroxyethanesulfonate

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

Properties:
Solid sodium 2-hydroxyethyl sulfonate is a colorless, free-flowing, non-hygroscopic solid, which dissolves readily in water and has good biodegradability.
Due to the method of synthesis samples often contain traces of sodium sulfite or sodium hydrogen sulfite causing aqueous solution to possesses a mildly alkaline pH of about 10.

Uses:
The main use of sodium 2-hydroxyethyl sulfonate is the production of the isethionate class of surfactants.
These are readily foaming and particularly mild, making them suitable for cleaning sensitive skin and are therefore mainly used in baby soaps and shampoos.
Because of its pronounced skin compatibility sodium 2-hydroxyethyl sulfonate is added to soaps and liquid skin cleansers with up to 15 parts by weight.

From sodium 2-hydroxyethyl sulfonate the so-called biological buffers such as HEPES, MES, PIPES etc. are easily accessible.
The addition of 2-hydroxyethyl sulfonate to electroplating baths allows higher current densities and lower concentrations than the much more expensive methane sulphonic acid with improved appearance.
Sodium isethionate,more commonly called Sodium Isethionate,is a sodium salt derived from coconut oil.
Sodium Isethionate's a common ingredient that is often used as a replacement for animal-derived sodium salts

Sodium Isethionate finds its way into soaps and cleansers because it acts as a surfactant, which means that it helps to bind chemical compounds that don't typically dissolve in water.
In the case of its use in soaps, it helps water cling to the dirt and oil on your skin, allowing them to be washed away.
Because of its mild nature, it's also often found in toothpastes and in baby soaps, too.
Sodium Isethionate is a colorless, syrupy, strongly acidic liquid that can form detergents with oleic acid

Sodium Isethionate is not regularly found in liquid detergent systems due to its limited solubility in water.
This study focuses on the understanding of enthalpy of solubilization, equilibrium of solubilization, and the structures and properties of Sodium Isethionate and various surfactants.

The purpose of this exercise is to help the formulator to find appropriate surfactant systems to keep Sodium Isethionate in aqueous solution.
The solubility of Sodium Isethionate in water is unfavorable in terms of enthalpy of solvation.
When setting up equilibrium of solubilization, there are three possible phases, and three methods have been developed to prevent Sodium Isethionate from recrystallizing in aqueous solutions.

The first focuses on tying cocoyl isethionate ions within micelles made of secondary surfactants.
The second focuses on the exchange of sodium ions with ammonium ions (and/or triethanolammonium).
The third centers on emulsification of Sodium Isethionate and the subsequent change of micelles into emulsified oil drops.
A combination of two or three of these methods will enable the formulator to use Sodium Isethionate as the primary surfactant in liquid detersive system.

Sodium isethionate is a mild surfactant (cleansing agent) derived from isethionic acid and coconut fatty acids.
