## Abstract

Cleaning compositions of surfactant-based products containing one or more alkaline builders for the preparation of liquid cleaning compositions are discussed. The surfactant-based product may be any type of cleaning product based on surfactants. Methods of cleaning a household surface and of making cleaning compositions are also discussed.

## Claims

### Claim 1

A cleaning composition comprising:
(i) an ethoxylated or propoxylated nonionic surfactant;
(ii) an anionic surfactant other than a fatty acid soap;
(iii) an olefin/maleic acid copolymer that consists of a C8 olefin/maleic acid copolymer;
(iv) a fatty acid or a salt thereof;
(v) an alkaline builder;
(vi) a thickening agent; and
(vii) an abrasive material.

### Claim 2 (depends on 1)

The composition of claim 1, wherein the ethoxylated or propoxylated nonionic surfactant is a C9-C11 alcohol ethoxylate.

### Claim 3 (depends on 1)

The composition of claim 1, wherein the alkaline builder is chosen from alkali metal or alkaline earth metal phosphates, pyrophosphates, phosphonates, citrates, silicates, borates, carbonates, hydroxides, bicarbonates; monoethanolamine, diethanolamine, triethanolamine; sodium tripolyphosphate; trisodium phosphate; tetrasodium pyrophosphate; sodium acid pyrophosphate; sodium monobasic phosphate; sodium dibasic phosphate; sodium hexametaphosphate; sodium metasilicate; sodium silicates; sodium carbonate; sodium sulfate; borax (sodium tetraborate); ethylene diamine tetraacetic acid tetrasodium salt; and trisodium nitrilotriacetate.

### Claim 4 (depends on 1)

The composition of claim 1, further comprising a solubilizing agent chosen from ethanol, hexylene glycol, pentaethylene glycol hexyl ether, triethylene glycol hexyl ether, sodium chloride, sodium cumene sulfonate, sodium xylene sulfonate or a mixture thereof.

The composition of claim 1, wherein the fatty acid or a salt thereof is a C10-C22 carboxylic acid sodium salt.

### Claim 6 (depends on 1)

The composition of claim 1, wherein the thickening agent is chosen from an inorganic clay or a natural gum.

### Claim 7 (depends on 1)

The composition of claim 1, wherein the abrasive material is chosen from chalk, silica, alumina, sodium silicate, zirconium silicate, sodium carbonate, sodium citrate or a mixture thereof.

### Claim 8 (depends on 1)

The composition of claim 1, wherein the anionic surfactant is present in an amount of about 0.1% to about 8%.

### Claim 10 (depends on 1)

The composition of claim 1, wherein the copolymer is present in an amount of about 0.01% to about 3%.

### Claim 11 (depends on 1)

The composition of claim 1, wherein the alkaline builder is present in an amount of about 0.01% to about 3%.
