Sodium isethionate

Sodium isethionate is an amphoteric detergent used in detergent bar soaps. It makes a dense lather in addition to the lather made by the soap. It is nondrying and mild on the skin. It works equally well in soft or hard water. It is also an antistatic agent in shampoos. [Pg.211]

Sodium cocoyl isethionate is a related amphoteric detergent used in mild bath soaps, toothpastes, and baby soaps. [Pg.211]

No matter how much fun it is to squish our toes in the mud, most people love to be clean. We want our clothes to be fresh, our dishes to be spotless, and our cars to be shiny. We continue to invent new ways to make things clean. [Pg.211]

Detergents have molecules with one side that prefers water (hydrophilic), and another side that prefers oils and fats [Pg.211]

Detergents and soaps are surfactants, which is short for surface-active agent.  [Pg.212]

The viscous fatty acid chloride is mixed with soHd sodium isothionate and is heated under vacuum and agitation without water or solvent HCl is evolved, leaving the product as a finely divided powder. The direct esterification of fatty acid and sodium isethionate has been patented (69). [Pg.242]

In addition to the soaps and fatty acids, some bars contain cocamidopropyl betaine, a mild amphoteric detergent that is added to control irritation without decreasing suds or cleaning power, and benzine sulfonate detergents such as sodium dode-cylbenzinesulfonate. Other detergents, such as sodium isethion-ate and sodium cocoyl isethionate, are also common. [Pg.209]

As a historical note, SAI for Dove was made by this acyl chloride process until a commercial process for direct esterification of fatty acid and sodium isethionate was developed by Lever Brothers Co. in the late 1950 s. The SAI made by direct esterification is generally termed DEFI, an acronym for directly esterified fatty isethionate . The DEFI reaction is follows ... [Pg.278]

Chemistry and general properties. Sodium isethionate is 2-hydroxyethane sulphonate, sodium salt and will form an ester with a fatty acid halide, normally an acyl chloride (Figure 4.26). [Pg.129]

Raw materials. Sodium isethionate is produced by the reaction of ethylene oxide with sodium bisulphite. The most common commercially available isethionates are based on coconut fatty acid. [Pg.130]

Raw materials. N-methyl taurine is the reaction product of sodium isethionate and methy-lamine (see Figure 4.28). Taurine can be made by using ammonia instead of methylamine, but has little use in surfactants. [Pg.131]

Acyl Isethionates are ester-type anionic surfactants formed by monocarboxylic acids and isethionic acid HOCH2CH2SO3H. The latter is formed by reaction of 30 % aqueous sodium bisulphite and ethylene oxide at 70 C [66]. All commercial isethionates (as sodium cocoyl isethionate) are esters derived from natural carboxylic acids by esterification of the acids or acyl chlorides with sodium isethionate ... [Pg.30]

For a better colour it is advantageous to curry out the esterification for up to 90 % conversion and under some excess of sodium isethionate [73]. Acyl isethionates derived from acyl chloride are formed under milder conditions but contain NaCl. [Pg.30]

The hydrolytic stability of a surfactant can be enhanced critically if the condensation is carried out with sodium methyltaurate instead sodium isethionate, for example [10,56,74] ... [Pg.31]
