<p>A stable bleaching and brightening composition is provided comprising (a) an active halogen source; (b) an amine oxide surfactant; (c) a stilbene sulfonic acid type FWA; and (d) a pH adjusting agent; and wherein the ratio of amine oxide:FWA is 3:1 to 10:1. A preferred method for making the composition is to prepare a concentrated surfactant solution of at least 20% surfactant, then dissolve the FWA therein to form a stable premix. The active halogen source, pH adjusting agent and any option ingredients are then combined with the premix. The resulting composition has good brightener and hypochlorite stability, and good brightener solubility.</p> |
