Patent number: 5133933Abstract: The present invention relates to microbiocidal composition and methods for the preparation and use of of such compositions. Properly used in accordance with the present invention, these microbiocidal compositions are effective in killing or inhibiting a wide variety of harmful, destructive or offensive microorganisms including viruses, bacteria, yeasts, algae and molds. The microbiocidal compositions of the present invention are suitable for use with conventional detergents to provide microbiocidal cleansing agents. The microbiocidal compositions can also be mixed with a liquid to provide an effective disinfectant. The microbiocidal additive can be incorporated into plastic materials and various synthetic fibers thereby imparting microbiocidal activity to the plastic materials or fibers.Type: GrantFiled: March 7, 1990Date of Patent: July 28, 1992Assignee: Interface Research CorporationInventor: Robert H. McIntosh

Patent number: 4647601Abstract: The present invention relates to self-sanitizing epoxy resin and to an additive which is incorporated therein so that the epoxy product or film is made self-sanitizing.The additive is an alkyl phosphate derivative with the following structure: ##STR1## where R is an alkyl group of from 8 to 18 carbon atoms, R.sub.1 is an alkyl group or a hydroxy alkyl group, and R.sub.2 is selected from the group consisting of hydrogen and an alkyl group of from 6 to 18 carbon atoms, with at least one R.sub.2 group being the alkyl group.The additive is highly effective against both gram-negative and gram-positive bacteria and is also highly effective against eukaryotic microorganisms such as yeasts, molds and fungi. In addition to the unique and unexpected microbiocidal properties of the self-sanitizing epoxy, the microbiocidal activity remains in the epoxy product or film over long periods of time.Type: GrantFiled: May 21, 1985Date of Patent: March 3, 1987Assignee: Interface Research CorporationInventor: Robert H. McIntosh
