Abstract
The invention relates to a series of polyglycoside derivatives that contain water-soluble groups introduced into the molecule by reaction with the hydroxyl groups present in the starting polyglycoside molecule. The preferred products have more than one water-soluble group per molecule and are made with mild reagents to avoid discoloration and mal odor. The most preferred products have between 2 and 3 functional groups per molecule. The compounds are amino functional and betaine functional alkyl polyglucoside.

A surfactant composition which comprises a mixture of compounds conforming to the following structures:
- wherein;
- R is alkyl having 8 to 22 carbon atoms;
- R1, R2, R3, and R4 are independently selected from the group consisting of
- —CH2—CH(OH)—CH2—N—(CH2CH2OH)2
- and H, with the proviso that R1, R2, R3, and R4 are not all H;
- and
- wherein;
- R is alkyl having 8 to 22 carbon atoms;
- R5, R6, R7, R8;
- R9, R10 and R11 are independently selected from the group consisting of
- —CH2—CH(OH)—CH2—N—(CH2CH2OH)2
