The cleaning solution and a pressurizable container having a removably mounted cap with an aerosol valve assembly can be provided as a kit to a consumer for preparing a pressurized cleaning solution.Type: ApplicationFiled: December 19, 2008Publication date: July 9, 2009Applicant: BISSELL HOMECARE, INC.Inventors: Christian J.

Patent number: 7553805Abstract: The present invention is drawn to methods of treating disease or injury. In particular, the invention provides methods for treating viral infections, bacterial infections, fungal infections, and cancerous tissue. The methods include the administration of an aqueous composition that can comprise an aqueous vehicle, including water, from 0.0001 wt % to 10.0 wt % of a peroxygen, and optionally, an alcohol. Additionally, from 0.0001 ppm to 50,000 ppm by weight of a transition metal based on the aqueous vehicle content can also be present. Alternatively or additionally, the transition metal can be in the form of a colloidal transition metal, such as colloidal silver or alloy thereof.Type: GrantFiled: August 31, 2006Date of Patent: June 30, 2009Assignee: Solutions Biomed, LLCInventors: Daryl J. Tichy, Brian G. Larson

Patent number: 7547671Abstract: A removal cleaning agent for discolored sections of titanium building materials which comprises at least a water-soluble inorganic acid salt, an organic acid or organic acid salt, a surfactant and a hydrophilic oxygen-containing hydrocarbon solvent, and optionally an discoloration inhibitor, fluoracarbon resin and polishing material. In the cleaning method for discolored sections of titanium building materials, coating is carried out with a bristle brush and a sponge roller, the coated film sections are polished with a nonwoven fabric or foam resin, optionally after aging, and then the discolored sections are removed by washing with water.Type: GrantFiled: September 24, 2003Date of Patent: June 16, 2009Assignee: Nippon Steel CorporationInventors: Michio Kaneko, Kiyonori Tokuno, Hiroshi Shimizu, Takateru Dekura

Publication number: 20090149368Abstract: By introducing droplets of an aqueous suspension, in which particles of a diacyl peroxide are suspended and in which at least one polysaccharide crosslinkable by metal ions is dissolved, into a solution, which comprises metal ions crosslinking the polysaccharide, it is possible to prepare pellets which comprise particles of a diacyl peroxide embedded into a matrix. The pellets are suitable as a bleaching component in cleaning compositions.Type: ApplicationFiled: August 21, 2006Publication date: June 11, 2009Applicant: Evonik Degussa GmbHInventors: Jens Hildebrand, Stefan Leininger, Georg Schick, Harald Jakob
