The present invention relates to a solid enzyme cleaning composition in which the enzyme is stable in the presence of mixtures of carbonate and bicarbonate at alkaline pH, and methods employing this composition. The enzyme cleaning composition preferably employs weight ratios of carbonate and bicarbonate to stabilize one or more enzymes in a solid, a concentrate, and/or a use composition, and at temperatures higher than ambient.

Stable solid enzyme compositions and methods employing them

The present invention relates to methods for cleaning, rinsing, and/or antimicrobial treatment of medical carts, medical cages, and other medical instruments, devices or equipment. The method for cleaning employs a solid alkaline, for example a solid carbonate, cleaning composition for cleaning the medical cart, cage, instrument, device, or equipment. The method for rinsing employs a solid neutral or neutralizing rinse composition for rinsing the medical cart, cage, instrument, device, or equipment. The method for antimicrobial treatment employs a solid, for example a solid quaternary ammonium or solid halogen, antimicrobial composition, for antimicrobial treatment of the medical cart, cage, instrument, device, or equipment.

Methods and compositions for cleaning, rinsing, and antimicrobial treatment of medical equipment

Hard floor finishes and other stubborn soils can be removed using an aqueous dispersion of an alkylene glycol phenyl ether solvent combined with an ether alcohol solvent/coupler. Each component is used at a concentration that result in the creation of a visible dispersed appearance of the aqueous dilute use solutions. We have found that the alkylene glycol phenyl ether, in combination with at least one ether alcohol coupler or solvent, interacts with the aqueous medium to surprisingly provide enhanced cleaning performances. Hard to remove soils such as highly crosslinked urethanes and acrylic materials can be solubilized and removed by the alcohol solvent dispersions of the invention. We have found that the alkylene phenyl ether solvent requires a specific coupler cosolvent for activity. Such activity can be enhanced by the presence of a second coupler cosolvent and the use of a specific class of nonionic surfactant materials.
