Patent ID: 7285522

Claim:
A method of preparing an aqueous bleaching solution with improved textile whitening performance, said method comprising: (i) addition to an aqueous wash liquor of a solid composition comprising: a) 10 to about 90 weight % of a hypohalite-generating compound; b) 1 to about 90 weight % of a bromide-releasing compound; c) 0.001 to about 10 weight % of a fluorescent whitening agent; d) optionally, 0.001 to about 50 weight % of an alkalinity source; wherein said bromide-releasing compound provides between 0.5 to about 1.0 moles of bromide ion per mole of available chlorine in said solution, and wherein said solution increases the measured textile whitening performance versus a control by a ΔW value of greater than about 3.0, wherein said fluorescent whitening agent is not hypohalite bleach stable, wherein the physical form of said solid composition is selected from the group consisting of a granule, tablet, and combinations thereof.
