    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:

    wherein R1 and R2 may be the same or different and are selected from liner or branched hydrocarbon chains with carbon numbers 8 to 22;
    R3 is H, SO - y M + , or -O(CH2CH2O) n X;
    R4 is SO - y M + , or -O(CH2CH2O) 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 - y M + .
    Preferably, in the above composition when R3 is other than H, R3=R4.
