Abstract
A liquid hard surface cleaning composition comprising, by weight, 1% to 20% of water-insoluble, particulate abrasive having a particle size in the range of 1 to 40 microns; 3% to 15% of a synthetic, organic, anionic detergent; 1% to 7.5% of an ethyleneoxylated alkanol nonionic detergent, the weight ratio of anionic detergent to nonionic detergent being from 1.75:1 to 3:1; 1% to 15% of a detergent builder salt, the weight ratio of builder salt to total detergent being in the range of 1:4 to 2:1; and an aqueous medium; the proportions of the components being so adjusted within the specified ranges that some of the detergent is present in liquid crystal form and the abrasive is maintained in stable suspension.
Claims11
A stable, opaque, liquid hard surface cleaning composition comprising, by weight, from 1% to 20% of a water-insoluble, particulate, inorganic abrasive having a particle size in the range of 1 to 40 microns;
- from 3% to 12% of a water-soluble, synthetic, organic, anionic detergent salt of a sulfuric reaction product having a C.sub.6 -C.sub.22 alkyl group and either a sulfonic acid or sulfuric acid radical in its molecular structure;
- from 2% to 4% of a water-soluble condensation product of a C.sub.8 -C.sub.22 alkanol and 2 to 15 moles of ethylene oxide, the weight ratio of anionic detergent to nonionic detergent being from 1.75:1 to 3:1;
- from 1% to 15% of water-soluble inorganic or organic detergent builder salt, the weight ratio of builder salt to total detergent being in the range of 1:4 to 2:1;
- and an aqueous medium;
- the proportions of the components being so adjusted within the specified ranges that some of the detergent is present in liquid crystal form and the abrasive is maintained in stable suspension, said composition having a viscosity in the range of 350 to 1500 centipoises.
