摘要

There are disclosed surfactants consisting of esters of bi- or tri-carboxylic hydroxyacids having general formula: <CHEM> wherein: X = H, -CH2COOR; Y = H, OH, on condition that Y=H when X = -CH2COOR; R, R1, R2, which may be the same or different, are H, an alkaline or alkaline-earth metal, -NH4, a cation of an ammonium organic base or an A radical selected from the group comprising etherified (C6-C16) alkyl polysaccharides containing from 2 to 6 saccharide units and etherified (C6-C16)hydroxyalkyl aliphatic polyalcohols containing from 2 to 16 hydroxyl groups and wherein at least one of said R, R1, R2 is an A radical.
