Abstract: Method and apparatus for treating dishware, in which the method comprises the steps of providing a treatment composition comprising a photoactive component, contacting in an appliance the treatment composition with the dishware, and irradiating the treatment composition with visible light. The step of irradiating the treatment composition with visible light is performed with a source of light that is tool free insertable into and removable from the appliance.

Abstract: Photoactivators comprise a photoactive moiety and a hydrophilic moiety. The photoactivators preferably comprise less than about 35%, by weight of the photoactivator, of the photoactive moiety. The photoactivators can be activated to a photo-excited state by excitation with incident radiation of a wavelength between about 350 nm and 750 nm, preferably between about 350 nm and about 420 nm. The photoactivators further encompass those having certain chemical formulations.

Abstract: Consumer product compositions comprise a water soluble organic photoactivator, an electron acceptor which accepts an electron from the photoactivator when the photoactivator is in a photo-excited state and/or reduced state, and a benefit active precursor which converts into a benefit active agent via electron transfer. The electron acceptor is preferably not covalently linked to the photoactivator. Also disclosed are methods of making a benefit active, comprising exposing the consumer product compositions to light, preferably having a wavelength greater than about 350 nm.

Abstract: Method and apparatus for treating laundry.

Abstract: Systems for treating a surface comprise a first composition and a second composition. The first composition comprises a water soluble organic photoactivator. The second composition comprises an electron acceptor which accepts an electron from the photoactivator when the photoactivator is in a photo-excited state and/or reduced state and a benefit active precursor which converts into a benefit active agent via electron transfer. Methods for treating a surface comprise applying the first composition to the surface, applying the second composition to the surface, and exposing the surface to light.
