Appl. No.:

10/112177

Inventors:

William R. Peterson - Phoenix AZ
David Giaccio - Phoenix AZ
Renee E. Berman - Chandler AZ

Assignee:

Coating Systems Laboratories, Inc. - Chandler AZ

International Classification:

A61K 31695

US Classification:

514 63, 556413, 424 63, 424609

Abstract:

A method for application to the skin of aqueous compositions containing antimicrobial organosilane quaternary ammonium compounds, which remain on the skin, are substantive to it and reduce or eliminate bacteria, viruses and fungi present and prevent future contamination by their presence and substantive character. All formulations are aqueous solutions which may be scented and/or colored and all contain a water soluble, organosilicon quaternary ammonium compound or mixture thereof; specifically 3-(trimethoxysilyl)-propyloctadecyl-dimethyl ammonium chloride or 3-(trimethoxysilyl)propyldidecylmethyl ammonium chloride and the trisilanol, polysiloxanol and water soluble polysiloxane derivatives thereof.

C09K 312

US Classification:

252 72

Abstract:

Methods and compositions for dehydrating, passivating and coating HVAC and refrigeration systems having fluid enclosures are provided. The methods include adding a composition including organometalloid and/or organometallic compounds to the system, allowing the compositions to react with water in the system and sealing the system. The organometallic compounds include at least one alkoxy, carboxy and/or enoxy functional group bound to the metal element within the compound. The organometalloid compounds include at least one enoxy functional group bound to the metalloid element within the compound. Compositions for sealing such systems are also provided. The sealing compositions also include one or more organometallic compounds having at least one enoxy, carboxy and/or alkoxy group and/or organometalloid compounds which include at least three hydrolyzable groups, at least one of which is an enoxy group. When added to the system the sealing compositions exit an opening, react with atmospheric moisture and an external surface of the system and seal the opening.
