ABSTRACT:
Mild and environmentally benign bis-alkylphenol alkoxylated gemini surfactants of the formula: ##STR1## wherein R independently represents alkali, R.sub.1 independently represents hydrogen EO represents ethyleneoxy radicals alkyl, R.sub.2 independently represents hydrogen, --SO.sub.3 M, --P(O) (OM).sub.2, --CH.sub.2 COOM, --CH.sub.2 CHOHCH.sub.2 --SO.sub.3 HM, wherein M represents hydrogen, alkyl or alkaline earth metal, ammonium or an organic base salt; R.sub.3 represents alkylene of from one to about 10 carbon atoms or --C(O)--R.sub.4 --C(O)-- wherein R.sub.4 represents alkylene or aryl, and --O--R.sub.5 --O-- wherein R.sub.5 represents aliphatic or aromatic moieties with the proviso that when R.sub.3 is alkylene, then R.sub.2 is not hydrogen, and a and b are numbers ranging from one to about 100, with the proviso that when R.sub.2 is hydrogen, b is not zero.
