ABSTRACT:
Nonionic polyalkoxylated glucoside surfactant compositions useful in forming stable emulsions with oil in saline solutions comprising: ##STR1## wherein each R is individually selected from the group consisting of a hydrogen and a methyl group; wherein the sum of w+x+y+z is from about 4 to about 40; and wherein m is from about 2 to about 15; and wherein R' is selected from the group consisting of an alkyl group having about 6 to about 20 carbon atoms, an alkenyl group having about 6 to about 20 carbon atoms and an alkyl aryl group having about 10 to about 20 carbon atoms.
These surfactant compositions are made by reacting the corresponding alkoxylated lower alkyl glucoside with a hydrophobic alkoxylated alcohol by means of an alcohol interchange reaction (transacetalation). These surfactant compositions may be employed in enhanced oil recovery processes and other applications where good emulsification and high salinity tolerances are required, such as textiles, leather, dairy, concrete grinding aids and drilling muds.
