Isethionate esters

Despite its potential application to charged surfactant analysis, there have been relatively few publications of ion chromatography applications. Dionex in their applications literature demonstrate several possible separations including alkyl sulphates the separation of sodium isethion-ate from its alkyl isethionate ester on a Vydac 302 IC column with methanol 20mM phthalic acid water (3 5 12, 2.5) and conductivity detection is described in [49]. [Pg.230]

The presence of unreacted sodium isethionate can be detected from the NMR spectrum (130). Quantitative analysis is usually performed by ion chromatography. Nonsuppressed ion chromatography is suitable for analysis of isethionate esters, using a Vydac 302 IC column, 4.6 x 250 mm, using a mobile phase prepared from 150 mL methanol and 250 mL 0.020 M phthalic acid, diluted to 1 L with water (131). Conductivity detection is suitable. Separation of the isethionate from chloride and surfactant is excellent. Extended contact of the sample with the mobile phase is to be avoided, as this can cause hydrolysis of the ester to produce additional isethionate ion. [Pg.47]

Most bar soap is indeed soap. A few products consist of synthetic detergent. The products most often used are isethionate esters, alcohol sulfate, and alkyl glyceryl ether sulfonate. [Pg.606]

Fatty esters of isethionic acid were first produced by the I.G. Farbenindustrie in the early 1930s under the trade name Igepon A. A two-step synthesis is required [3]. [Pg.632]

Acyl isethionate could also be classed as an interrupted soap but, unlike ether carboxylates, the additional functionalityis added after the carboxylate and the labile metal ion are replaced with an ester, terminated in a sulphonate group. [Pg.129]

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]

The chemistry of taurates is analogous to isethionates, with the ester link replaced by an amide. This gives taurate improved stability to temperature and pH compared to the equivalent isethionate. [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]

In a similar way, the fatty acid can be attached to 2-hydroxyethanesulfonic acid, thus forming an ester instead of an amide. The sodium salt is the so-called sodium isethionate (2). [Pg.278]

There are several approaches utilized to develop skin-friendly dishwashing formulations. The first approach is to select mild surfactants. Some examples of mild surfactants are the ethoxylated alcohols, alkyl polyglucosides, and although not commonly used in dishwashing detergents, sulfo-succinate esters and isethionates. [Pg.48]

Oxidation from thiol through to sulphonic acid in one step can be accomplished by peracids [233], or activated H2O2 systems, including molybdates, tungstates [234] and ferrous salts [235] among the catalytic activators. Isethionic acid can be prepared from 2-thioethanol [236], and sulpho esters from thio esters [237]. [Pg.291]
