Abstract

The present invention relates to mildly alkaline bathroom and/or hard surface cleaners providing improved foam performance. In particular, a concentrated, preferably disinfecting, high performance foaming cleaning composition is disclosed which can reduce or eliminate the need for scrubbing on bathroom and other hard surfaces. Methods of use are further disclosed for bathroom and/or other hard surface cleaning. The foam has increased stability for a period of time, followed by dissipation with an audible “crackling” sound and easy rinsability.

First claim

What is claimed is:

1 . A foamable cleaning composition comprising:
a) one or more foaming surfactants b) one or more foaming synergists, and c) one or more foaming antagonists, with the remainder being water or other functional components, said composition having a pH of from 7.0 to 12.5.

2 . The cleaning composition of claim 1 , wherein the foaming surfactant is an amphoteric surfactant.

3 . The cleaning composition of claim 1 or 2 , wherein the foaming surfactant is an amine oxide surfactant.

4 . The cleaning composition of any of claims 1-3 wherein said amine oxide surfactant is one or more of the following: lauryl dimethyl amine oxide, cocamine oxide, and/or octyl dimethyl amine oxide.

5 . The cleaning composition of any of claims 1-4 wherein said foaming synergist is a solvent.

6 . The cleaning composition of any of claims 1-5 wherein said solvent is one or more of the following: diethylene glycol butyl ether, diethylene glycol ethyl ether, propylene glycol, hexylene glycol or cocamidopropyl PG-dimonium chloride phosphate.

7 . The composition of any of claims 1-6 wherein said foaming antagonist has antimicrobial activity.

8 . The cleaning composition of any of claims 1-7 , wherein said foaming antagonist is a quaternary ammonium compound.

9 . The cleaning composition of any of claims 1-8 wherein said quaternary compound is dodecyl dimethyl ammonium chloride.

10 . A foamable cleaning composition comprising:
a) from about 0.5 wt-% to about 20 wt-% of a foaming surfactant b) from about 0.5 wt-% to about 15 wt-% of a foaming synergist, and c) from about 0.5 wt-% to about 20 wt-% of a foaming antagonist, with the remainder being water, or other functional components, said composition having a pH of from 7.0 to 12.5.

11 . The cleaning composition of claim 10 , wherein the foaming surfactant is an amine oxide surfactant.

12 . The cleaning composition of claim10 or 11 wherein said amine oxide surfactant is selected form the group comprising lauryl dimethyl amine oxide, cocamine oxide, and/or octyl dimethyl amine oxide.

13 . The cleaning composition of any of claims 10-12 wherein said foaming synergist is a solvent.

14 . The cleaning composition of any of claims 10-13 wherein said foaming synergist is one or more of the following: diethylene glycol butyl ether, diethylene glycol ethyl ether, propylene glycol, hexylene glycol, or coacmidopropyl PG-dimonium chloride phosphate.

15 . The composition of any of claims 10-14 wherein said foaming antagonist has antimicrobial activity.

16 . The cleaning composition of any of claims 10-15 wherein said foaming antagonist is a quaternary ammonium compound.

17 . The cleaning composition of any of claims 10-16 wherein said quaternary compound is dodecyl dimethyl ammonium chloride.

18 . A method of cleaning a hard surface to remove soil and/or debris comprising;
applying a foaming cleaning composition comprising: from about 0.5 wt-% to about 20 wt-% of a foaming surfactant; from about 0.5 wt-% to about 15 wt-% of a foaming synergist, and from about 0.5 wt-% to about 20 wt-% of a foaming antagonist, to the surface; allowing the foam to dissipate, and thereafter rinsing said surface to that said composition and said soil and/or debris are removed.

19 . The method of claim 18 wherein said foam dissipation takes about 2 to 3 minutes.

20 . The method of any of claim 18 or 19 wherein said foam dissipation results in an audible cracking sound.

21 . The method of any of claims 18-20 wherein said hard surface is a bathroom surface,

22 . The method of any of claims 18-21 wherein said hard surface is one of the following: stainless steel, aluminum, copper, vinyl, plastic, metal, glass, rubber (natural and synthetic), formica, wood, mild steel, melamine, brass, ceramic, or stone.

23 . The method of any of claims 18-22 wherein said surface is a nonhorizontal surface.

24 . The method of any of claims 18-23 wherein said nonhoriztonal surface is on a toilet, glass, mirror, shower, transportation vehicle, or wall.
