Abstract

An abrasive scouring cleanser composition consisting essentially of a water-insoluble siliceous abrasive material; an alkali metal carbonate; a water-soluble organic detergent; and calcium oxide or hydroxide. Compositions exhibiting desirable cleansing and scouring properties and effective in the removal of smears or deposits of soft metals such as aluminum or porcelain or ceramic surfaces are described.

Claims

1. An abrasive scouring cleanser composition consisting essentially of from 60 to 95 percent by weight of a water-insoluble siliceous abrasive;

from 0.1 to 10 percent by weight of a water-soluble organic detergent; and

alkali metal carbonate detergency builder salt; and

a calcium compound selected from the group consisting of calcium oxide, calcium hydroxide and mixtures thereof;

the weight ratio of the calcium compound to the alkali metal carbonate builder salt being from 0.01;

1 to 0.4;

1.

2. The abrasive scouring cleanser composition of claim 1 wherein the water-insoluble siliceous abrasive has a particle size less than about 0.3 mm. in diameter.

3. The abrasive scouring cleanser composition of claim 2 wherein the water-insoluble siliceous abrasive is present in an amount of from about 80 to about 90 percent by weight.

4. The abrasive scouring cleanser composition of claim 1 wherein the water-soluble organic detergent is a water-soluble synthetic anionic detergent.

5. The abrasive scouring cleanser composition of claim 4 wherein the water-soluble synthetic anionic detergent is an alkylbenzene sulfonate and is present in an amount of from 1 percent to 4 percent by weight.

6. The abrasive scouring cleanser composition of claim 1 wherein calcium compound is calcium oxide and the alkali metal carbonate detergency builder salt is sodium carbonate.

7. The abrasive scouring cleanser composition of claim 6 wherein the weight ratio of calcium oxide to sodium carbonate ranges from 0.02:

1 to 0.3;

1.

8. The abrasive scouring cleanser composition of claim 1 wherein the calcium compound is calcium hydroxide and the alkali metal carbonate is sodium carbonate.

9. The abrasive scouring cleanser composition of claim 8 wherein the weight ratio of calcium hydroxide to sodium carbonate ranges from 0.02:

1 to 0.3;

1.

10. The abrasive scouring cleanser composition of claim 1 wherein the calcium compound is lime, the alkali metal carbonate is sodium carbonate and the ratio of lime to sodium carbonate ranges from 0.02:

1 to 0.3;

1.

11. The abrasive scouring cleanser composition of claim 1 wherein the alkali metal carbonate is sodium carbonate and is present in an amount of from 8 percent to 14 percent;

and the calcium compound is calcium oxide or hydroxide and is present in an amount of from 0.3 percent to 1 percent.
