Abstract

A microbicidal organic polymer material for use in manufacturing of contact lenses, condoms, surgical sutures and gloves, medical examination devices and similar uses is provided by polymers to which is tightly adsorbed a disinfectant organic dye. Many polymers such as polyvinyl chloride and acrylic polymers show exceptional avidity for a number of microbicides, of acidic, basic, aromatic and/or hydrophobic character such as methylene blue and gentian violet. Consequently, devices constructed of these polymeric materials release no free dye to an aqueous solution. The material is generally a natural or synthetic polymer that releases no particles or fines into wounds or body orifices. Presence of adsorbed disinfectant organic dye allows the polymer to inhibit microbial growth in a number of different situations. Several common microbes are killed by being incubated in the present of an embodiment of the invention which contains a combination of methylene blue and gentian violet.
