AI Technical Summary

Benefits of technology

[0009] It has been recognized that it would be advantageous to develop germicidal composition with enhanced microbiocidal activities for killing microbiological spores, microbiological outgrowth from spores, and vegetative microorganisms. The invention provides a germicidal composition with enhanced microbiocidal activities for killing microbiological spores, microbiological outgrowth from spores, and vegetative microorganisms and a method of use thereof.

Problems solved by technology

Reducing agents that reduce disulfide cystine linkages in proteins and enzymes that attack peptidoglycan linkages also weaken the spore coat and increase permeability of the spore.

Abstract

Germicidal compositions with enhanced activity towards killing microbiological spores and vetgetative cells comprising certain quaternary ammonium compounds (QACs), phenolic compounds, monohydric alcohols, hydrogen peroxide, iodine, triclocarban, triclosan or combinations thereof with one or more spore coat opening agents. The invention also provides for the application of the germicidal compositions to animate and inanimate surfaces to help kill germs and protect against the risk of infection from bacteria, molds, yeasts, fungi, viruses, and microbiological spores.

Description

PRIORITY DATA [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 346,216, filed on Jan. 16, 2003, which claims the benefit of U.S. Provisional Application No. 60 / 350,416 filed on Jan. 18, 2002, each of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to germicidal disinfecting compositions. More particularly, the present invention relates to a novel concept for germicidal disinfecting compositions that are effective in killing both vegetative microorganisms and microbiological spores in a single composition. [0004] 2. Related Art [0005] Microbiological spores are among the most resilient forms of dormant life known to man. Although formed by many different types of microbiological organisms, the most commonly studied spores are from various Bacillus or Clostridium species. In particular, Bacillus spores are amazingly resistant to common sterilizing techn...
