Abstract

A disinfecting and sanitizing article is adapted for use on objects to be disinfected and sanitized, including skin and hands and nonporous hard surfaces. The article is formed from a porous substrate formed from an absorbent fibrous matrix. A disinfecting and sanitizing agent is formed as a liquid composition that is absorbed into the substrate. The composition is formulated from an organic solvent present in a concentration of about 10 percent to 40 percent by weight, a surfactant present in a concentration of about 0.5 percent to 20 percent by weight, one or more pathogen killing agents present in a concentration of about 0.255 percent to 10.5 percent by weight, an emollient present in a concentration of about 0.05 percent to 3.0 percent by weight, and water present in a concentration of about 50.0 percent to 89.9 percent by weight. Application of the article provides an abrasive disinfecting and sanitizing action by a scrubbing action on the surface of the object to disinfected and sanitized.

Claims

1. An abrasive disinfecting and sanitizing article, consisting essentially of, in combination to obtain a slower drying time of its liquid composition:

a towel substrate formed from an absorbent fibrous matrix, the substrate having two opposed surfaces, at least one of the opposed surfaces having an abrasive component permanently attached thereto or an integral part thereof; and

,

a disinfecting and sanitizing agent formed as a liquid composition in the substrate, the agent formulated from;

an organic solvent being an alcohol present in a concentration of about 10 percent to 40 percent by weight;

a nonionic surfactant system present in a concentration of about 0.5 percent to 20 percent by weight wherein the nonionic surfactant comprises a mixture of linear secondary alcohols reacted with ethylene oxide;

one or more pathogen killing agents present in a concentration of about 0.255 percent to 10.5 percent by weight, wherein the one or more pathogen killing agents are dual chain quaternary (N-alkyldimethylethylbenzyl chloride, N-alkyldimethylethylbenzyl ammonium chloride), ortho phenyl phenol, paratertiary amyl phenol and parachlorometaxylenol;

an emollient present in a concentration of about 0.05 percent to 3.0 percent by weight, the emollient being an aloe vera gel providing a slower drying time of the liquid composition;

a pH modifying agent present in a concentration of about 0.05 percent to about 2.0 percent by weight; and

water present in a concentration of about 50.0 percent to 89.9 percent by weight,

wherein the abrasive component accounts for about 10 percent to 90 percent of a surface area of the at least one of the opposed surfaces,

and wherein application of the substrate with the agent absorbed therein on object to be disinfected and sanitized provides an abrasive disinfecting and sanitizing action by a scrubbing action on the object.

2. A disinfecting and sanitizing kit, consisting essentially of, in combination, to obtain a slower drying time of a liquid composition:

an air-tight container configured to retain a liquid, and retard evaporation of the liquid, the container having a lid that is closable to substantially prevent evaporation of the liquid;

an abrasive porous substrate formed from an absorbent fibrous matrix, the substrate being disposed in the container and the substrate being formed as a plurality of singulatable towels, each towel having two opposed surfaces, at least one of the opposed surfaces having an abrasive component permanently attached thereto or an integral part thereof;

a liquid composition disinfecting and sanitizing agent the liquid composition being absorbed in the substrate to form a disinfecting and sanitizing article, the liquid composition comprising;

an organic solvent being an alcohol present in a concentration of about 10 percent to 40 percent by weight,

a nonionic surfactant system present in a concentration of about 0.5 percent to 20 percent by weight, wherein the nonionic surfactant comprises a mixture of linear secondary alcohols reacted with ethylene oxide;

one or more pathogen killing agents present in a concentration of about 0.255 percent to 10.5 percent by weight, wherein the one or more pathogen killing agents are dual chain quaternary (N-alkyldimethylethylbenzyl chloride, N-alkyldimethylethylbenzyl ammonium chloride), ortho phenyl phenol, paratertiary amyl phenol and parachlorometaxylenol;

an emollient present in a concentration of about 0.05 percent to 3.0 percent by weight, the emollient being an aloe vera gel and providing a slower drying time for the liquid composition,

a pH modifying agent present in a concentration of about 0.05 percent to about 2.0 percent by weight, and

water present in a concentration of about 50.0 percent to 89.9 percent by weight,

wherein the abrasive component accounts for about 10 percent to 90 percent of a surface area of the at least one of the opposed surfaces, and

wherein the article is adapted for use on an object to be disinfected and sanitized, including skin and hands and nonporous hard surfaces, and

wherein application of the article provides an abrasive disinfecting and sanitizing action by a scrubbing action on the surface of the object, and

wherein the article is stored in the container to maintain the article is a wetted condition.

3. The disinfecting and sanitizing kit in accordance with claim 2 wherein the towels are formed as a roll of towels having a series of perforations therein to singulate the towels from one another.

4. The disinfecting and sanitizing kit in accordance with claim 2 wherein the towels are formed as a series of interfolded towels.

5. The disinfecting and sanitizing kit in accordance with claim 2 wherein the container has an opening therein through which singulatable towels are withdrawn from the container.
