Abstract
A surfactant composition comprising the formula: ##STR1## wherein X is: ##STR2## wherein R and R.sub.1 independently represent the same or different C.sub.1 to C.sub.36 straight or branched chain alkyl, alkene, aryl, alkylaryl and arylalkyl, said R and R.sub.1 optionally further characterized as containing ether, thioether, polyalkylene oxide, amine or quaternary ammonium, amide or ester groups; or are substituted thereby with the open valence filled by R.sub.3 wherein R.sub.3 is hydrogen or R, n is a whole number from 2 to about 4, m is 0 to 10, v is 0 or 1, w is 0, 1, or 2 and x and y are whole number integers of from 1-50. More specifically, R and R.sub.1 can individually represent: ##STR3## wherein R.sub.2 independently is selected from the group defined by R and z is 0 or a whole integer.

A surfactant composition comprising the formula:
- ##STR15## wherein X is:
- ##STR16## wherein R and R.sub.1 independently represent the same or different C.sub.1 to C.sub.36 straight or branched chain alkyl, alkylene, aryl, alkylaryl and arylalkyl, said R and R.sub.1 optionally further characterized as containing ether, thioether, polyalkylene oxide, amine or quaternary ammonium, amide or ester groups;
- or are substituted thereby with the open valence filled by R.sub.3 wherein R.sub.3 is hydrogen or R, n is a whole number from 2 to about 4, m is a number of from 1 to 10, v is 0 or 1;
- w is 0, 1, or 2 with the further stipulation that both w's cannot be 0, and x and y are whole number integers of from 1-50.

- ##STR22## wherein X is:
- ##STR23## wherein R and R.sub.1 independently represent the same or different C.sub.1 to C.sub.36 straight or branched chain alkyl, alkylene, aryl, alkylaryl and arylalkyl, said R and R.sub.1 optionally further characterized as containing ether, thioether, polyalkylene oxide, amine or quaternary ammonium, amide or ester groups;
- or are substituted thereby with the open valence filled by R.sub.3 wherein R.sub.3 is hydrogen or R, n is a whole number from 2 to about 4, m is a number of from 1 to 10, v is 0 or 1;
- w is 0, 1, or 2 with the further stipulation that both w's cannot be 0, and x and y are whole number integers of from 1-50 and at least one additional surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants and mixtures thereof.
