Abstract
A thickening system for laundry products incorporates low levels of a fluorescent whitening agent or dye, a surfactant and an acidic pH adjusting agent. At the acidic pH, the fluorescent whitening agent precipitates as a colloidal particle, and is stabilized by associating with the surfactant, resulting in thickening. Optionally, a C.sub.6-18 soap synergistically increases viscosity. The thickening system may be formulated with a bleaching product and preferably with a peroxide bleach product.
