Abstract
Abstract The present invention relates to microbiocidal compositions 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. In addition, the microbiocidal compositions of the present invention can be incorporated into a wide variety of permanent and nonpermanent coating materials including, but not limited to, paints, varnishes, epoxy coatings and waxes. The microbiocidal compositions can also be used as preservative for protecting wood and wood products from damage by microorganisms or insects. The microbiocidal compositions of the present invention can also be used to kill or repel insects.
