CA 1078375

Abstract of the Disclosure To obtain nonionic surfactants having solubility and stability in relatively strong aqueous solution of caustic, salt or other electrolytes, corn starch or a similar source of glucose units is reacted with an alcohol containing up to about 4 carbon atoms to obtain a glycoside somewhat more lipophilic than the saccharide, and then the resulting glycoside is reacted with a hydrophobic oxirane-containing material such as a C? to C18 epoxyalkane or a glycidyl ether having about the same number of carbon atoms.
