Abstract
The present invention relates to a new class of carbohydrate based nonionic surfactant, i.e., alkyl and alkenyl glycasuccinimide, and a process for their manufacture.
Claims2
A nonionic alkyl- or alkenyl bis(glyca)succinamide surfactant compound having the formula:
- ##STR112## wherein A.sub.2 is selected from the group consisting of the following structures which are attached to the succinate ring via the nitrogen atom on said structures:
- ##STR113## A.sub.1 is A.sub.2, OR.sub.12, N(R.sub.12).sub.2 group or mixtures thereof;

- W is a CH.sub.2 group, oxygen atom or mixtures thereof;
- R.sub.9 is a straight or branched chain saturated hydrocarbon radical having about 4 to about 24 carbon atoms;
- R.sub.12 is hydrogen, an alkyl, alkenyl or hydroxyalkyl group having about 1 to about 4 carbon atoms or mixtures thereof;
- R.sub.13 is hydrogen, a straight or branched chain saturated or unsaturated hydrocarbon which may be unsubstituted or substituted with a hydroxyl, polyhydroxyl radical having about 1 to about 6 carbon atoms;
- c=1;
- d=1-4;
- e=0-5;
- m=0;
- n=1-4;
