<p>Concentrated heavy duty liquid laundry detergent compositions containing an anionic surfactant component, polyhydroxy fatty acid amide surfactant and a water-soluble salt of toluene sulfonic acid, and containing no more than about 50 % water. The concentration of all surfactants in the detergent compositions is greater than about 10 % by weight of the composition. The anionic surfactant component comprises between about 50 % and 100 % alkyl polyethoxylate sulfates. The compositions are substantially clear and isotropic when prepared and remain stable after extended periods of time and under extreme conditions. Toluene sulfonate salts, although known hydrotropes, provides improved phase stability to the compositions unlike other standard hydrotopes and solvents.</p> |
