Abstract
Abstract High sudsing phosphate-free heavy duty detergent composition comprises a compound of the formula ##EQU1## in which R 1 and R 2 are substantially linear saturated or unsaturated aliphatic groups of 3 to 19 carbon atoms, R 3 is alkylene of 2 to 4 carbon atoms, u, v, x and y are 0 or 1, z is an integer 1 to 4, M is H or a water-soluble salt-forming cation, the sum of the carbon atoms in R 1 and R 2 is 13 to 21, the sum of the unsaturated sites in R 1 and R 2 is 0 to 1, the sum of u and v is 1, the sum of x and y is 1, and the sum of u and x is 1, and as a foam enhancing component, from 0.05 to 0.30 parts by weight of an essentially straight chain primary alcohol of 11 to 14 carbon atoms.
