Abstract

Isotropic liquid detergent composition comprises specific soil antiredeposition polymers containing a hydrophilic backbone and monomer with hydrophobic side chains. When the molar ratio of the number hydrophilic groups to number of hydrophobic groups on said polymers is below certain critical levels, it has been unexpectedly found that the stability (i.e., clarity) of the composition remarkably increases. The solubility of the polymer is further dependent on the type and amount (minimum required) of hydrotrope; surfactant type and levels; and minimum electrolyte levels.
