<p>Sugar-derived gemini surfactants contain two disaccharide moieties as the hydrophilic groups that are linked by a bridge. The compounds have general structure (I), wherein R and R1 are the same or different linear, branched, saturated, or unsaturated hydrocarbyl moieties with a carbon chain length of from about C6-C23 and Y and Y1 are the same or different alcohol-containing moieties having at least two and preferably more hydroxyl containing groups such as glucose, fructose, lactose, and the like, and one but not both may be hydrogen, and X is a R2 or -COR2CO- wherein R2 is a C1 to C20 straight or branched chain alkyl, aryl, alkylaryl, dicarboxyaryl, or diaminoalkyl.</p> |
