Abstract
A polymeric body covering article that generates and releases gas upon activation by electromagnetic energy and/or moisture. The gas provides antimicrobial and/or antiodor protection to objects in contact or in proximity to the interior surface of the article and/or to objects in contact or in proximity to the exterior surface of the article.
Claims16
A glove for reducing microbiological contamination and/or odor, the glove comprising a gas releasing monolayer, the gas releasing monolayer prepared from a composition comprising:
- from about 74% to about 99% by weight of a plastisol comprising PVC resin and a plasticizer;
- from about 0.005% to about 3% by weight of a thixotropic agent;
- from about 0.01% to about 3% by weight of a dispersing agent;
- and
- from about 0.5% to about 20% by weight of a gas-generating composition which is capable of generating and releasing at least one gas selected from chlorine dioxide, chlorine, sulfur dioxide, carbon dioxide and/or nitrous oxide,
- the gas being released from the glove upon exposure of a surface of the glove to light and/or humidity.
A glove for covering a portion of a mammalian body wherein the glove, when exposed to light and/or moisture, is capable of reducing odor and/or microbiological contamination on the portion of the body and reducing odor and/or contamination of a surface in contact with the glove, wherein the glove comprises a gas releasing monolayer, the gas releasing monolayer prepared from a composition comprising:
- from about 74% to about 99% by weight of a plastisol comprising PVC resin and a plasticizer;
- from about 0.005% to about 3% by weight of a thixotropic agent;
- from about 0.01% to about 3% by weight of a dispersing agent;
- and
- from about 0.5% to about 20% by weight of a gas-generating composition which is capable of generating and releasing at least one gas selected from chlorine dioxide, chlorine, sulfur dioxide, carbon dioxide and/or nitrous oxide,
- the gas being released from the glove upon exposure of a surface of the glove to light and/or humidity.
A method of using a gas-releasing body covering article to reduce microbiological contamination and/or odor, the method comprising:
- contacting a portion of a mammalian body with a body covering article;
- exposing the body covering article to light and/or humidity to generate at least one gas, the body covering article comprising a gas releasing monolayer prepared from a composition comprising
- from about 74% to about 99% by weight of a plastisol comprising PVC resin and a plasticizer,
- from about 0.005% to about 3% by weight of a thixotropic agent, from about 0.1% to about 3% by weight of a dispersing agent, from about 0.5% to about 20% by weight anions which are capable of generating and releasing the at least one gas selected from chlorine dioxide, chlorine, sulfur dioxide, carbon dioxide and/or nitrous oxide,
- and a colorant capable of changing color when oxidized by the gas;
- and
- monitoring the color change of the colorant as an indicator of gas-releasing activity.
