Abstract
The present invention is directed to a liquid toilet bowl cleaning and sanitizing composition comprising an aqueous dispersion of particles of at least one halogen donating compound wherein said particles have a surface modifier absorbed on the surface thereof in an amount sufficient nanometers (nm). The compositions of the present invention can contain other conventional ingredients in toilet bowl cleaning compositions such as enzymes, surfactants, perfumes, dyes and other similar ingredients. In a preferred embodiment the composition contains: PA1 0.2-10.0 Weight percent surfactant; PA1 35.0-75.0 Weight percent halogen donating nanoparticles; PA1 1.0-7.0 Weight percent dye; PA1 0-3.0 Weight percent alkali; PA1 0.05-0.5 Weight percent fragrance; and PA1 20.0-40.0 Weight percent water.
