ABSTRACT:
Detergent active materials capable of heavy duty washing in the absence of phosphates comprising linear alkyl hydrocarbyloxybenzene disulfonates of the formula ##STR1## in which R is linear alkyl of 10 to 24 carbon atoms, X is H or a water-soluble salt-forming cation, Z is H, or an alkyl group of 1 to 6 carbon atoms and Y is H, alkyl of 1 to 6 carbon atoms, alkenyl of 2 to 6 carbon atoms, or aralkyl of 7 to 9 carbon atoms, Y and Z may be polymethylene chain of 2 to 7 carbon atoms, the sum of the aliphatic carbon atoms in R and --CH--YZ is from 17 to 25, and for this purpose an aromatic carbon atom is considered equal to 2/3 aliphatic carbon atom.
