Claims (20)

1. A foaming or bubbling carpet cleaning composition comprising:

a) a glycol ether organic solvent; wherein the solvent is selected from either a mixture of dipropylene glycol methyl ether and dipropylene glycol n-butyl ether or propylene glycol n-propyl ether

b) a non-ionic surfactent;

c) a propellant; and

d) water,

the composition may contain at least one hydrotope,

the composition optionally contains at least one cationic surfactant, at least one corrosion inhibitor, pH buffeting agents, perfumes, perfume carriers, pH adjusting agents, pH buffers, antioxidants, antimicroblals, germicidals, fungicidals, acaricides, allergen neutralizer and preservatives,

wherein the foam breaks within ten minutes of application to the carpet.

3. The composition of claim 1 wherein the non-ionic surfactant is a primary alcohol ethoxylate or a secondary alcohol ethoxylate.

4. The composition of claim 3 wherein the non-ionic surfactant is a secondary alcohol ethoxylate.

5. The composition of claim 4 wherein the non-ionic surfactant is a primary alcohol ethoxylate of formula RO(CH 2 CH 2 O) n H wherein R is a mixture of linear, even carbon-number hydrocarbon chains ranging from C 12 H 25 to C 16 H 33 and n represents the number of repeating units and is a number of from about 1 to about 12.

6. The composition of claim 1 wherein the foam breaks within or the bubbling action lasts for less than five minutes of application to the carpet.

7. The composition of claim 6 wherein the foam breaks within or the bubbling action lasts for at least one minute of application to the carpet.

8. The composition of claim 7 wherein the foam breaks within or the bubbling action lasts for at least thirty seconds of application to the carpet.

9. The composition of claim 8 wherein the foam breaks within or the bubbling action lasts for at least fifteen seconds of application to the carpet.

10. The composition of claim 1 wherein the solvent (a) is a mixture of dipropylene glycol methyl ether and dipropylene glycol n-butyl ether.

11. The composition of claim 1 wherein the hydrotope is selected from the group consisting of sodium cumene sulfonate, sodium xylene sulfonate, di-sodium mono- and di-alkyl disulfonate diphenyloxide, and n-octane sodium sulfonate.

12. The composition of claim 11 wherein the hydrotope is sodium cumene sulfonate.

13. A process for the removal of stains from carpeting which comprises the step of applying an effective amount of the composition according to claim 1 to a carpet needing such treatment.
