<p>Marginally soluble fluorescent whitener agents (optical brigtheners) can be made hypochlorite bleach resistant, stable and formulated into concentrated aqueous hypochlorite solutions and into detergent compositions where the aqueous fluorescent whitener agent-bleach solution contains from 0.001 weight percent to about 5.0 weight percent fluorescent whitener agent and from 1.5 weight percent to about 20 weight percent sodium hypochlorite. The fluorescent whitener agent is one that is marginally soluble in water at or near room temperature and, according to the method of the invention, is present in crystalline form.</p> |
