Alkyl citrates structure

Cesalpina Chemicals, a subsidiary of Lamberti Spa., Italy, introduced some years ago three nonionic alkyl polyglycoside esters, namely citrates, sulfosuccinates and tartrates, that can be used in personal care applications [54], The synthesis starts with alkyl polyglycoside (typically C12/14), which is esterified with citric acid, maleic anhydride and tartaric acid, respectively. The succinate is further sulfonated. Structures are shown in Figure 4.5 [55].
