摘要：
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 liner or branched hydrocarbon chains with carbon numbers 8 and 22;R3 is H, SO.sup.-.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.-.sub.y M.sup.-.Preferably, in the above composition when R3 is other than H, R3.dbd.R4.
