Abstract
A cleansing composition is disclosed with household and personal care applications and comprises a monopersulfate oxidizing agent and a halide bleaching promoter, to which is added an effervescence promoting compound comprising a perborate salt. The resulting composition is operable and capable of effervescing at an alkaline pH, at which it is also a more effective cleanser.
In a further embodiment, the above cleansing composition may include a colorant and a fade control agent comprising a compound providing a soluble halide ion for applications where it is desirable that the color provided by the colorant will fade within a given period of time. Small quantities of the fade control compound are effective, and do not disturb the desired initial color intensity of the solution provided by the colorant.
