Abstract
The invention relates to a series of polyglycoside derivatives that contain water-soluble sulfosuccinate groups introduced into the molecule by reaction with the hydroxyl groups present in the starting polyglycoside molecule, with the chloro material. 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.
