Abstract

New anionic derivatives of mono and polyglycosides which are surface-active agents are described which anionic derivatives have the general formula ##STR1## wherein G is a glycosyl moiety which is derived from a reducing sugar selected from the group consisting of fructose, glucose, mannose, galactose, talose, gulose, allose, altrose, idose, arabinose, xylose, lyxose, ribose or mixtures thereof, R is an alkyl group substituted at the reducing carbon of the reducing sugar from which the glycosyl moiety, G, is derived, said alkyl group being straight chain or branched chain having 6 to 30 carbon atoms, x=1 to 10, at least one of the hydroxyl groups of at least one of the glycosyl moieties (or of a hydroxyalkyl group attached directly or indirectly to a hydroxyl group of said glycosyl moiety) has a Z group substituted in place of said hydroxyl group, Z is a substituent which is ##STR2## O(CH.sub.2).sub.p CO.sub.2 M, OSO.sub.3 M, O(CH.sub.2).sub.p So3.sub.m and mixtures thereof and R.sub.1 =(CH.sub.2).sub.2 CO.sub.2 M or CH=CHCO.sub.2 M, but Z=O.sub.2 M only if Z is in place of a primary hydroxyl group in which case the primary hydroxyl-bearing carbon atom, --CH.sub.2 OH, is oxidized to form a ##STR3## M=H+, an organic cation or inorganic cation, B=H-, CH.sub.3 - or CH.sub.3 CH.sub.2 -, t=0 to 10, t'=0 to 10, t'=0 to (3x+1), p=0 to 10, and y=1 to 3x+1.
