Sulfonates, alkyl glyceryl ether

Although essentially pure soap products continue lo dominate the cleansing-bar field, a few products contain synthetic surfactams in addition 10 soap to act as scum and curd dispersants. Synthetic surfactants used in this application include alkyl sulfates, alkyl glyceryl ether sulfonates, alkyl esters of sodium isothionale. and alkylamides of N-melhyl tauride. 

Miscellaneous—Including two other comparatively minor products—amine oxides and alkyl glyceryl ether sulfonates.

Alkyl glyceryl ether sulfonates are found in some dishwashing liquids, shampoos, and detergent bars and are primarily used to enhance skin emolliency though some claims are made for "cleaning ability."...

It is important to note here that once again an inuniscible liquid system is encountered and good contact between the two phases is essential. A small amount of the alkyl glyceryl ether sulfonate product can be used as a seed to emulsify the two phases and provide more intimate contacting to increase the rate of reaction. ...

There appears to be a synergy between SMEs and sulfonated fatty acids, which allow for improved foam and feel of a soap bar while retaining ease of production. Existing equipment used to make pure soap bars may be able to make combo SME/sulfonated fatty acid/soap bars. Surfactants currently used in combo soap bars include alkylether sulfates, sodium cocoylisethionates, alkyl glyceryl ether sulfonates, and betaines. Incorporation of these surfactants generally requires special equipment and processing. 

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.
