Abstract
A substantially homogeneous sprayable cleaning gel composition which is substantially free of suspended encapsulated particles exhibits extended dwell time when sprayed on to a surface as compared to a low viscosity spray cleaner. The extended dwell time and anti-static properties of the sprayable cleaning gel composition give rise to several benefits and advantages. The sprayable cleaning gel composition housed in a spray applicator is usable to clean surfaces at any angle. A preferred method of cleaning surfaces is also described.
Claims9
A sprayable cleaning gel composition which is free of suspended encapsulated particles, consisting essentially of:
- from about 75% to about 98% by weight of a liquid carrier;
- from about 0.005% to about 20% by weight of a surfactant component comprising at least one surfactant selected from the group consisting of nonionic, anionic, cationic, amphoteric, and zwitterionic surfactants and mixtures thereof;
- from about 0.001% to about 5% by weight of a carboxylic acid copolymer dispersant;
- from about 0.01% to about 2% by weight of a high molecular weight powdered, crosslinked polyacrylic acid thickener;
- from about 1% to about 20% by weight of at least one supplemental solvent for dissolving oil-based particles in water, said at least one supplemental solvent being selected from the group consisting of:
- ethylene glycol ethers;
- and
- propylene glycol ethers;
- and
- from about 0.05% to about 1.0% by weight of a nonionic ester complex anti-static agent;
- wherein said sprayable cleaning gel composition has a gel consistency having a viscosity ranging from about 900 centipoise to about 5,500 centipoise.

A packaged cleaning gel composition for cleaning surfaces, comprising:
- a sprayable cleaning gel composition which is free of suspended encapsulated particles, consisting essentially of:
- from about 75% to about 98% by weight of a liquid carrier;
- from about 0.005% to about 10% by weight of a surfactant component comprising at least one surfactant selected from the group consisting of nonionic, anionic, cationic, amphoteric, and zwitterionic surfactants and mixtures of the above;
- from about 0.001% to about 5% by weight of a carboxylic acid copolymer dispersant;
- from about 0.01% to about 2% by weight of a high molecular weight powdered, crosslinked polyacrylic acid thickener;
- from about 1% to about 20% by weight of at least one supplemental solvent for dissolving oil-based particles in water, said supplemental solvent selected from the group consisting of:
- ethylene glycol ethers;
- and
- propylene glycol ethers;
- and
- from about 0.05% to about 1.0% by weight of a nonionic ester complex anti-static agent;
- wherein said sprayable cleaning gel composition has a gel consistency having viscosity ranging from about 900 centipoise to about 5,500 centipoise;
- and
- a spray applicator comprising:
- a container having a reservoir for holding said sprayable cleaning gel composition therewithin;
- a spray head movably connected with said container, said spray head having an orifice therein, said reservoir being in fluid communication with said spray head and said orifice when said spray head is selectively moved in relation to said container, and
- means for propelling said sprayable cleaning gel composition sprayably through said orifice responsively to said selective movement of said spray head.

A method for cleaning a surface, comprising the steps of:
- spraying a sprayable cleaning gel composition which is free of suspended encapsulated particles, consisting essentially of:
- from about 75% to about 98% by weight of a liquid carrier;
- from about 0.005% to about 20% by weight of a surfactant component comprising at least one surfactant selected from the group consisting of nonionic, anionic, cationic, amphoteric, and zwitterionic surfactants and mixtures thereof;
- from about 0.001% to about 5% by weight of a carboxylic acid copolymer dispersant;
- from about 0.01% to about 2% by weight of a high molecular weight powdered, crosslinked polyacrylic acid thickener;
- from about 1% to about 20% by weight of at least one supplemental solvent for dissolving oil-based particles in water, said at least one supplemental solvent being selected from the group sonsisting of:
- ethylene glycol ethers;
- and
- propylene glycol ethers;
- and
- from about 0.05% to about 1.0% by weight of a nonionic ester complex anti-static agent;
- having a viscosity from about 900 centipoise to about 5,550 centipoise onto a surface to be cleaned, wherein said sprayable cleaning gel composition clings to and dwells on said surface rather than running downwardly thereon due to gravity at standard temperature and pressure;
- spreading said sprayable cleaning gel composition selectively around said surface with a wiping article;
- and
- wiping said sprayable cleaning gel composition off said surface via the wiping article to thereby clean the surface.
