Abstract
An acidic bathroom and/or multi-purpose cleaner providing corrosion protection in the absence of a corrosion inhibitor when present in a metal container, such as an aluminum container, is described. The corrosion protection is provided by the inclusion in the cleaner of a combination of one or more organic acids and one or more anionic surfactants present in the cleaner. The cleaner has a pH equal to or less than 3. The cleaner may also include a nonionic surfactant and has an aqueous carrier, such as purified water. The cleaner can be an aerosol or a non-aerosol cleaner.
Claims24
An acidic bathroom and/or multi-purpose cleaner comprising
- (a) one or more organic acids;
- (b) one or more anionic surfactants;
- (c) optionally, one or more nonionic surfactants;
- (d) optionally, one or more fragrances;
- (e) optionally, a propellant component;
- and
- (f) an aqueous carrier;
- wherein a corrosion inhibitor is excluded from the acidic bathroom and/or multi-purpose cleaner,
- wherein the cleaner has a pH equal to or less than 3, and
- wherein the cleaner provides corrosion protection to interior surfaces of a metal container when the cleaner is stored in the metal container.
A combination product comprising
- (1) an acidic bathroom and/or multi-purpose cleaner including
- (a) one or more organic acids;
- (b) one or more anionic surfactants;
- (c) optionally, one or more nonionic surfactants;
- (d) optionally, one or more fragrances;
- (e) optionally, a propellant component;
- and
- (f) an aqueous carrier;
- wherein a corrosion inhibitor is excluded from the acidic bathroom and/or multi-purpose cleaner, and
- wherein the cleaner has a pH equal to or less than 3;
- and
- (2) a metal container in which said bathroom and/or multi-purpose cleaner is stored and dispensed from in use, wherein the cleaner reduces corrosion of interior surfaces of the metal container when the cleaner is stored in the metal container.
An acidic bathroom and/or multi-purpose cleaner comprising
- (a) one or more organic acids which includes citric acid;
- (b) one or more anionic surfactants which includes sodium dodecyl benzene sulfonate and sodium xylene sulfonate;

- (d) optionally, one or more fragrances;
- (e) optionally, a propellant component;
- and
- (f) a carrier which includes water;
- wherein a corrosion inhibitor is excluded from the acidic bathroom and/or multi-purpose cleaner,
- wherein the cleaner has a pH equal to or less than 3, and
- wherein the cleaner provides corrosion protection to interior surfaces of a metal container when the cleaner is stored in the metal container.
