1. A bleaching detergent composition comprising from about 0.001% to about 99%, by weight, of one or more mid-chain branched primary alkyl polyoxyalkylenes having the formula:

  • ##STR35## wherein the total number of carbon atoms in the branched primary alkyl moiety of this formula, including the R, R1, and R2 branching, but not including the carbon atoms in the EO/PO alkoxy moiety, is from 14 to 20, and wherein further the average total number of carbon atoms in the branched primary alkyl moieties having the above formula is within the range of greater than 14.5 to about 17.5;

    R, R1, and R2 are each independently selected from the group consisting of hydrogen and C1 -C3 alkyl, provided R, R1, and R2 are not all hydrogen and, when z is 1, at least R or R1 is not hydrogen;

    w is an integer from 0 to 13;

    x is an integer from 0 to 13;

    y is an integer from 0 to 13;

    z is an integer of at least 1;

    w+x+y+z is from 8 to 14; and

    EO/PO are alkoxy moieties selected from the group consisting of ethoxy, propoxy, and mixed ethoxy/propoxy groups, wherein m is at least about 1; and

    from about 1% to about 99.999%, by weight, of one or more detergent adjunct ingredients, said composition having a pH of 9 to 11 in use in an aqueous cleaning operation.
