Y is SO₂ M or SO₃ M,

Z is hydrogen or a methyl group, and

M is an alkali metal, alkylammonium or ammonium cation and mixtures of each of said sulfinate/sulfonate and said disulfonate with an ether monosulfonate having the following formula:

ROCH.sub.2 CH(Z)CH.sub.2 SO.sub.3 M

wherein:

R is a hydrocarbon group having from about 6 to about 24 carbon atoms,

Z is hydrogen or a methyl group, and

M is an alkali metal, alkylammonium or ammonium cation.
