Filed:

Nov 14, 2008

Appl. No.:

12/270896

Inventors:

Carl S. Weiss - Buffalo Grove IL, US
Anthony J. Wagner - Buffalo Grove IL, US
Wayne M. Rees - Racine WI, US

Assignee:

S.C. Johnson & Son, Inc. - Racine WI

International Classification:

A61L 9/015
A61L 9/00
A01N 59/16
A01N 25/00
A61K 33/24

US Classification:

424 762, 424 7621, 424405, 424617

Abstract:

Compositions, methods and apparatuses for reducing or eliminating malodors from indoor air are described. The method utilizes vapor phase hydrogen peroxide (VPHP) generated from either evaporation from an aqueous-based liquid composition or sublimation from a solid hydrogen peroxide-containing compound. VPHP engages a media coated with at least one transitional metal element or compound, which acts as an oxidation catalyst, in the presence of air that contains malodorous compounds to provide increased efficacy of malodor molecule oxidation. The apparatus can employ a disposable porous non-woven filter pad coated with one or more transition metal compounds, and a solid source of VPHP. Malodor-containing air engages the pad in the presence of the VPHP to effectively oxidize the malodorants. The apparatus can also include a mechanism to provide color change(s) in the presence of VPHP to indicate whether the device contains VPHP or not.

Carl Weiss - Buffalo Grove IL, US

John Schroeder - Racine WI, US

International Classification:

A61L 9/00
A61L 101/38

US Classification:

424076200

Abstract:

Improved single-phase aerosol spray air sanitizers are disclosed. The preferred active ingredient for the air sanitization is a high concentration of triethylene glycol (TEG), made possible in the single-phase aerosol formulation by the use of dimethyl ether (DME) as a propellant. The combination of TEG and DME enables high concentrations of TEG to be utilized in a single-phase aerosol formulation. The formulation is useful for sanitizing air and removing bacteria and other malodorants from the air as well achieving higher bacteria kill rates than existing air sanitization formulations due to the high concentrations of TEG. Because the high concentration TEG aerosol formulation is a single-phase formulation, it can be utilized in automated spray or dispensing systems and does not require shaking or agitation prior to use.

Abstract:

Improved single-phase aerosol spray air sanitizers and deodorizers are disclosed. The preferred active ingredient for the air sanitization is a high concentration of triethylene glycol (TEG), in a single-phase aerosol formulation made possible by the use of dimethyl ether (DME) as a propellant. The combination of TEG and DME enables high concentrations of TEG to be utilized in a single-phase aerosol formulation, without requiring the use of ethanol or water as co-solvents. The formulation is useful for sanitizing air and removing bacteria and other malodorants from the air as well achieving higher bacteria kill rates than existing air sanitization formulations due to the high concentrations of TEG. Because the high concentration TEG aerosol formulation is a single-phase formulation, it can be utilized in automated spray or dispensing systems and do not require shaking or agitation prior to use. Disclosed formulations leave little or no visible residue on hard surfaces when dispensed into the air of a room.
