Abstract
Stable, false body hard surface cleansers containing a false body fluid phase; relatively heavy abrasive particulate material suspended throughout the false body fluid phase and relatively light particulate filler material also suspended throughout the false body fluid phase. Such compositions can remain for extended periods of time as homogenous false body compositions exhibiting minimal tendency to form a separate liquid phase layer.
Claims11
An aqueous false-body hard-surface scouring composition having reduced tendency to form a liquid layer above said false-body compositions, said composition consisting essentially of:
- A. a continuous false-body fluid phase formed by admixing an aqueous liquid with an organic or inorganic colloid-forming agent capable of forming said liquid phase into a false-body fluid, such that the concentration of aqueous liquid ranges from about 30% to 90% by weight of the total composition and the concentration of the colloid-forming agent ranges from about 1% to 10% by weight of the total composition;
- B. relatively heavy, water-insoluble particulate abrasive material having particle diameters ranging from one micron to about 250 microns and a specific gravity equal to or greater than that of the continuous false body phase, said relatively heavy abrasive material being suspended throughout said continuous false-body fluid phase to the extent that the total concentration of relatively heavy abrasive material ranges from 2% to about 60% by weight of the total composition;
- and
- C. relatively light, water-insoluble particulate filler material having particle diameters ranging from one micron to about 250 microns and a specific gravity less that that of the continuous false body phase, said relatively light particulate material being suspended throughout said continuous false body fluid phase to the extent that the concentration of relatively light particulate material ranges from about 1% to 15% by weight of the total composition;
- wherein the ratio of the average particle diameters of the relatively heavy abrasive material and the relatively light filler material ranges from 0.25:1 to 2.1:1.
