IUPAC NAME: sodium;2-hydroxyethanesulfonate

Isethionates are esters of long-chain aliphatic carboxylic acids (C8 – C18) with isethionic acid (2-hydroxyethanesulfonic acid) or salts thereof, such as ammonium isethionate or sodium isethionate.
Isethionates are also referred to as acyl isethionates or acyloxyethanesulfonates.

Like the taurides, Isethionates are a class of particularly mild anionic surfactants which, unlike ordinary soaps, retain their washing-active properties even in hard water.
Isethionates are obtained on an industrial scale reacting mixtures of carboxylic acids with salts of isethionic acid under acidic catalysis e. g. with methanesulfonic acid.
The mixtures of carboxylic acids are obtained from the hydrolysis of animal fats (tallow) or vegetable oils, preferably coconut oil, but also palm oil, soybean oil or castor oil

Isethionates are solids which are often mixed with fatty acids (up to 30% by weight) to lower their freezing point.
Despite its low water solubility (100ppm at 25 °C), the lower-priced sodium cocoylisethionate has found more widespread use than its well water-soluble ammonium salt (> 25 wt.% at 25 °C).
To solubilize the sparsely soluble isethionates and taurides, the formation of mixtures with amphoteric surfactants (such as cocamidopropyl betaine) are proposed.
From such mixtures, Isethionates are possible to prepare liquid, clear and transparent aqueous concentrates which are liquid at room temperature.

Isethionates are characterized by excellent skin compatibility, excellent foaming (even in hard water), good cleansing properties and a pleasant skin feel.
Isethionates are non-toxic and readily biodegradable.
However, in contrast to the taurides, Isethionates are not long-term stable outside a pH range of 5 to 8.
Isethionates are used in solid soaps (so-called syndet bars) and in other personal care products such as lotions, washing and shower gels, shampoos, liquid soaps, shaving creams, and other cosmetic and dermatological preparations.

Isethionates is an anionic surfactant and a good foamer.
Isethionates offers benefits including soft after feel, mildness and biodegradability.

Isethionates is based upon fatty acids from natural, renewable coconut oil.
Isethionates is used in personal cleansing products like syndet bar, combo bars, foaming facial washes, body washes, shampoos, bath and showers gels and liquid soaps.

Isethionates are considered to be exceptionally mild for skin, hair, and eyes
Isethionates made from natural, renewable coconut oil

Isethionates is very mild to skin and eyes
Isethionates exhibits excellent foam and lather, performs well in hard water

Isethionates imparts a soft after-feel to skin or hair
Isethionates is great for solid cleansing bars, thus avoiding SLS and SLeS

Isethionates creates an opaque and creamy product when used with other surfactants in winter, but in our hot summers this effect can disappear
Isethionates is biodegradable

Soap has been used by humankind since ancient times and was probably already known to the Sumerians.
Isethionates is a fatty acid salt obtained from the reaction of a strong base with a fatty substance of animal (tallow) or plant origin (oil).

Isethionates functions as a:

-Moisturizer
-Emollient
-Cleanser
-Softener
-Conditioner
-Foaming Agent

Isethionates is a mild, biodegradable cleansing agent that is also a very good team-player next to other cleaning agents.
Isethionates is known for its good foam-boosing abilities while improving the mildness of the formula.
Isethionates's performance is similar to Isethionates, another group of cleaning agents known for their gentleness.

Isethionates is a fine white powder that's derived from coconut oil.
Isethionates's a sodium salt that's known to be gentle on the skin
The process of creating Isethionates includes mixing a natural sulfonic acid called isethionic acid with the fatty acids that naturally occur in coconut oil.
Isethionates are used in shampoos, body washes, cleansers, and bars of soap

Isethionates are used as cleansing agents because they mix well with both oils and water
The ingredient can mix with oils to lift dirt off the face, helping to rinse away any residue leftover from the day.

Isethionates helps to:

-Lift and remove dirt
-Hydrate the hair and skin to protect against dryness
-Create rich, foaming lather
-Prevent frizz
-Increase product viscosity
-Moisturize, condition, and soften
-Reduce tangling

Isethionates also a good emulsifier, foaming effectively to allow a rich lather while cleansing,"
Isethionates's used in products as an emulsifier because it reduces surface tension, which helps remove oil and dirt from the skin.
With each pump or squeeze, Isethionates helps lower the surface tension of water, which is what makes the cleanser lather and spread easier.
In other words, Isethionates is what makes the product lather so luxuriously when you apply it.
