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.
