Abstract

This invention is directed to a surfactant comprising a carbohydrate group that results in superior cleaning in a dry cleaning system. The surfactant has a hydrocarbon group that is more solvent-philic than a carbohydrate group, and can result in reverse micelle formation in a densified gas like densified carbon dioxide.
