In another aspect of the invention, the stabilizer incorporated into compositions containing a solvent, a surfactant, and water, and optionally a dye provides a beneficial cleaning result. In yet another aspect of the invention, the stabilizer beneficially retards the development of malodors when the compositions of the present invention are contained in a PVC container. Broadly, the incorporation of the stabilizer in said solvent can be employed to neutralize said impurities.Field of SearchSOLVENTS | |
