Abstract
The invention provides a homogenous, reduced scratching, liquid abrasive scouring cleanser comprising: PA0 (1) about 10-90% by weight scouring abrasive particles with a Mohs hardness of about 2 to 4, wherein a triple tiered weight distribution of said particles comprises PA1 (a) about 20-99% of the weight of said particles being particles having a diameter of greater than about 100 microns; PA1 (b) about 5-50% of the weight of said particles being particles having a diameter greater than abut 250 microns; and PA1 (c) about 0-30% of the weight of said particles being particles having a diameter greater than 300 microns; PA0 (2) a soil removal and suspension effective amount of a surfactant system comprising a mixture of anionic and nonionic surfactants; and PA0 (3) the remainder, water. Standard adjuncts known to those skilled in the art, namely buffers, colorants, fragrances, thickeners, viscosity modifiers and further surfactants can be added to these cleansers.
