Surface disinfectant with residual biocidal property

Abstract

A disinfectant formulation comprising a poly(2-ethyl-2-oxazoline) and a quaternary ammonium compound or combination of quaternary ammonium compounds is provided. A wipe having a residual biocidal property is also provided. The wipe formulation comprises a substrate comprised of a fibrous material, and the formulation present on or in the substrate. The formulation comprises a poly(2-ethyl-2-oxazoline), a quaternary ammonium compound or combination of quaternary ammonium compounds, a surfactant, water, and an optional fragrance.

AI Technical Summary

Benefits of technology

The present invention is about a disinfectant that has a residual biocidal property. The disinfectant is made by mixing a polymer binder, such as an oxazoline homopolymer or an extended or modified version of it, with a biocidal compound. The disinfectant also contains a carrier. The patent text describes the structure of the oxazoline homopolymer, which has different groups that can be attached to it. The invention also mentions other features of the disinfectant formulation and methods of making, using, and applying it.

Problems solved by technology

While some are beneficial to humans and the environment, others may have significant negative consequences for contaminated articles as well as the persons, animals and ecological members coming in contact with them.

Such maladies typically are fungal or bacterial infections and can afflict the victim locally or systemically.

As a result, these facilities house abnormally highly concentrated populations of patients with weakened immune systems.

Their resistance to one or more biocidal agents makes such infections particularly dangerous.

Nosocomial infections further deal a serious blow to the volume, quality, and cost of healthcare provided by hospitals and other institutions.

These programs typically include frequent hand-washing and frequent disinfection of surfaces.

Despite implementation of programs to curb nosocomial infections, infections still occur at unacceptably high rates.

A main disadvantage associated with consumer disinfectants and sanitizers is that, while they can be effective at initially killing microbes, the surface is easily and quickly re-contaminated through contact, airborne microbes, and un-killed residual microbes before treatment.

While some of the disinfectants would continue to offer some control if simply left on the surface, this would result in a greasy or tacky residue that would be easily negated by casual contact with the surface.

Thus, there is a desire for a home care and household cleaner that kills microbes quickly on contact, then acts as a residual disinfectant but yet does not have this undesirable sticky or tacky effect.

The food service industry also faces outbreaks in contamination of pathogens in the workplace and spreading disease out to consumers.

Even though food manufacturers adopt vigorous hygiene plans and comply with tight government hygiene regulations, major outbreaks of microbes are still reported occasionally that causes serious illness among consumers.

Biofilms present a large problem for public health because of increased resistance of biofilm-associated organisms to antimicrobial agents and for the potential of biofilm borne organisms to cause infections.

Current disinfectants do not have the ability to kill biofilms or to seal or lock-in biofilms on surfaces to prevent cross-contamination events and to prevent out growth.

There are limited solutions for surface biofilm problems.

For example, there is a building body of evidence that surface biofilms pose a problem in the healthcare setting for the above mentioned reasons.

In addition, biofilms are a recognized problem of possible contamination within the food industry.
