Abstract
In one embodiment, the present invention relates to novel two tail--two head and two tail--one head surfactants. In one embodiment, the present invention comprises a novel composition of matter having the general formula: ##STR1## wherein R1 and R2 may be the same or different and are selected from linear or branched hydrocarbon chains with from 6 to 22 carbon atoms; R3 is H, SO.sup.13.sub.y M.sup.+, or --O(CH2CH2O).sub.n X; R4 is SO.sup.--.sub.y M.sup.+, or --O(CH2CH2O).sub.n X; M is H, Li, Na, K, Rb or Cs; n is an integer from 2 to 50; y is 3 or 4; and, X is H or SO.sup.13.sub.y M.sup.+. Preferably, in the above composition when R3 is other than H, R3=R4.
