A disinfecting and sanitizing article comprises a substrate capable of absorbing and retaining a fluid and having two opposed surfaces wherein at least one surface is abrasive, and a nonabrasive liquid formulation for disinfecting and sanitizing is absorbed in the substrate, the liquid formulation comprising an oil-in-water emulsion, whereby initial disinfecting and sanitizing action is achieved by the combination of the abrasive surface of the substrate and the liquid formulation, and further disinfecting and sanitizing action is achieved after the biofilm is broken or dissolved by a combination of the emulsion and the abrasive substrate. Additional disinfecting and sanitizing action is achieved by the absorption of the pathogens into the substrate which has been saturated with disinfectants and sanitizers. The substrate can comprise a cloth-like towel.

This invention relates to cleaners and cleaning articles. More particularly, this invention relates to a disinfecting and sanitizing article.
Disinfectant and sanitizer compositions generally contain germ-killing chemicals of many different types and combinations with the specific intent of killing targeted pathogens. Some of these compositions are phenols, quaternary ammonium chlorides, glutaraldehydes and iodines. These formulations may contain surfactants generally of the non-ionic nature if cleaning properties are also desirable, and water to dilute the germ-killing chemicals to a safe user level. Other miscellaneous additives may also be used, such as perfumes, dyes, wetting agents, phosphates, silicates and solvents, to accomplish specific uses. These products can typically be offered in highly dilutable concentrations of up to one part of disinfectant and sanitizer to 256 parts of water. They may also be purchased in ready-to-use concentrations.
These types of products have to show complete kill of specific pathogens as required by the EPA to be registered for sale to the public. This kill ability is based on accepted laboratory tests under controlled environmental conditions, and kill rate of each pathogen is measured in contact time, which can vary from a few seconds to 20 minutes or longer. Also, the pathogens under conditions in laboratory testing are not contained in hard to remove biofilms such as are formed by dried blood, food grease, saliva and body fluids, which are typically found in actual use conditions in hospitals, nursing homes, restaurants, and many other sources of contamination. Biofilms are organic films or conglomerates under which pathogens can be located.
An example of the acceptable ranges of ingredients of the formulation embodied by this invention is as follows:
______________________________________ Ingredients Acceptable Range ______________________________________ Pathogen killing agents 0.255-10.5 Organic Solvent 10-30 Nonionic surfactant 0.5-2.0 pH modifier 0.1-2.0 Mineral oil 0.5-3.0 Water 50-87.4 ______________________________________
The acceptable ranges of ingredients associated with a preferred formulation in accordance with this invention is as follows:
