Solid sanitizers and cleaner disinfectants

Abstract

Solid sanitizing compositions have advantages over corresponding liquids and powders. A solid sanitizing product can be contained within a plastic bottle with a label indicating that the contents have antimicrobial or deodorizing properties containing a non-flowable solid composition having greater than about 0.02 percent by weight antimicrobial compounds. The preferred solid sanitizing compositions consist essentially of an antimicrobial compound selected from the group consisting of quaternary ammonium salts, fatty amines and diamines, chlorhexidine gluconate, phenol, derivatives of phenol, parachloro metaxylenol and mixtures thereof, and between 0 and 99.98 percent by weight of a cleaning composition. The solid sanitizing compositions can be effectively used with solid dispensers. The solid dispensers have a bowl with a drain at the bottom and an upward pointing spray nozzle. The spray nozzle directs water into an inverted bottle of the sanitizing composition to produce an aqueous solution of sanitizing compounds which drains from the bottom of the bowl. A second source of aqueous solution or fresh water can combine with the solution draining from the bowl to product a more dilute solution of sanitizing compounds. The relative flow into the spray nozzle and the secondary source can be adjusted to produce a final diluted solution with a desired dilution. Antimicrobial solutions can be used in a variety of industrial and institutional applications including laundry and hard surface cleaning. Four methods of producing the solid sanitizing compositions are described.
