Abstract
Abstract Novel nonionic gemini surfactants are extremely effective emulsifiers for oil-in-water emulsions that provide improved detergency at even low concentration levels. The surfactants are characterized by the formula: ##STR1## wherein R 1 is independently H or a C 1 to C 22 alkyl, R 2 is H or C 1 to C 22 alkyl and R 3 is D 1 --R 4 --D 1 or R 4 --D 1 --R 4 wherein R 4 is independently a C 1 -C 10 alkyl group, --C(O)--, --R 5 O(EO) a (PO) b !--, --O--R 5 --O--, or aryl, e.g. phenyl, and D 1 is independently --O--, --S--, --S--S--, --SO 2 --, --C(O)--, a polyether group --O(EO) a (PO) b --!, an amide group --C(O)N(R 6 )--!, an amino group --N(R 6 )--!, --O--R 5 --O--, or aryl. (EO) a (PO) b is a polyether group and Z is a C 1 -C 4 alkyl, or an alkylaryl or hydrogen wherein EO represents ethyleneoxy radicals, PO represents propyleneoxy radicals, a and b are numbers of from 0 to 100, a is preferably from about 0 to about 30 and b is preferably from about 0 to 10, and wherein a plus b is at least one.
