    • The invention provides methods, compositions and kits for increasing the brightness retention of a fabric laundered using a hypohalite-generating bleach by employing an amount of bromide-releasing compound sufficient to provide between 0.1 to about 1.5 moles of bromine ion to mole of available chlorine in a wash liquor to mitigate the negative effects of said hypohalite bleach on the optical brightener present in either the wash liquor or on said fabric. The invention also applies to fabrics washed using commercial laundry detergents which typically deliver an optical brightener into said wash liquor, said optical brightener generally exhibiting instability in the presence of said hypohalite bleaches. By employing the inventive methods and/or use of the inventive compositions, enhanced protection of the optical brightener is enabled, resulting in increased brightening of the laundered fabrics, determined versus a control as an increase in the Stensby whiteness measure of the fabric by a ?W value of greater than about 3.0.
    • 本发明提供了用于提高使用产生次卤酸盐的漂白剂洗涤的织物的亮度保持率的方法,组合物和试剂盒,其通过使用足以提供0.1至约1.5摩尔溴离子与 洗涤液以减轻所述次卤酸盐漂白剂对存在于洗涤液中或所述织物上的荧光增白剂的负面影响。 本发明也适用于使用商业洗衣洗涤剂洗涤的织物,其通常将荧光增白剂递送到所述洗涤液中,所述荧光增白剂通常在所述次卤酸盐漂白剂存在下表现出不稳定性。 通过使用本发明的方法和/或使用本发明的组合物,可以增强对荧光增白剂的保护,导致增强的洗涤织物的增亮,相对于对照而言,由于织物的斯滕斯比白度测量值的增加, W值大于约3.0。
