1. A surfactant blend comprising:

  • (a) 1 to 99% by weight of a polyalkyleneoxide polysiloxane having the general formula ##STR10## wherein x has a value of 1 or 2 and R1 has the formula --Cn H2n O(C2 H4 O)a (C3 H6 O)b R2wherein n has a value of 3 or 4,a has a value of 1 to 15,b has a value of 0 to 14,a+b has a value of 5 to 15, and each R2 is the same or different and is selected from the group consisting of hydrogen, an alkyl having 1 to 4 carbon atoms, and an acetyl group; and

    (b) 1 to 99% by weight of an organic compound having the general formula ##STR11## wherein R3 is the same or different and is selected from the group consisting of hydrogen and an alkyl having 1 to 4 carbon atoms;

    c has a value of 5 to 9,d has a value of 0 to 4,c+d has a value of 5 to 9, andt is 0 or 1R4 is a nonionic hydrophilic moiety with the proviso that when t is O, R4 is ##STR12## and when t is 1, R4 is selected from the group consisting of(i) [C2 H4 O]f [C3 H6 O]g H and(ii) (C6 H9 O5)h --C6 H10 O5wherein f has a value of 1 to 40,g has a value of 0 to 40, andh has a value of 1 to 4 wherein component (b) does not interfere with the spreading ability of component (a).
