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.
Claims8
A foamable cleaning composition comprising:
- a) from about 1 wt.-% to about 15 wt.-% of a foaming surfactant comprising one or more amine oxides selected from lauryl dimethyl amine oxide, cocamine oxide, myristyldimethylamine oxide, and octyl dimethyl amine oxide;
- b) one or more glycol solvent foaming synergists;
- c) from about 2 wt. % to about 12 wt. % of a foaming antagonist, wherein said foaming antagonist is a quaternary ammonium compound, and
- d) from 25 wt. % to about 40 wt. % of a chelating agent, wherein said chelating agent is diethylenetriaminepentaacetic acid, methylglycine-N,N-diacetic acid, glutamic acid-N,N-diacetic acid, aspartic acid-N,N-diacetic acid, or a salt thereof,
- with the remainder being water and optionally, other functional components, said composition having a pH of from 7.0 to 12.5 and free of cocamidopropyl phosphatidyl PG-dimonium chloride and alkyl polyglucosides.

A foamable cleaning composition comprising:
- a) from about 1 wt-% to about 15 wt-% of a foaming surfactant comprising one or more amine oxides selected from lauryl dimethyl amine oxide, cocamine oxide, myristyldimethylamine oxide, and octyl dimethyl amine oxide,
- b) from about 0.5 wt-% to about 15 wt-% of a glycol solvent foaming synergist,
- c) from about 2 wt-% to about 12 wt-% of a foaming antagonist, wherein said foaming antagonist is a quaternary ammonium compound, and
- d) from 25 wt. % to about 40 wt. % of a chelating agent, wherein said chelating agent is diethylenetriaminepentaacetic acid, methylglycine-N,N-diacetic acid, glutamic acid-N,N-diacetic acid, aspartic acid-N,N-diacetic acid, or a salt thereof,
- with the remainder being water, and optionally, other functional components, said composition having a pH of from 7.0 to 12.5 and free of cocamidopropyl phosphatidyl PG-dimonium chloride and alkyl polyglucosides.
