Abstract
An article is applied to the surface of an article, animal housing environment or animal (including humans) to provide antimicrobial activity when activated with a liquid comprising alcohol. The article may comprise a water and/or alcohol absorbent material; and a composition that reacts with water and/or alcohol to produce molecular iodine. The composition provides a local concentration (in the water and/or alcohol) of at least 5 or 10 parts per million iodine in water and/or alcohol carried by the material (that is actual water supported by the water absorbent material) when the material has 5% by weight of water present in the water absorbent.
Claims15
An article for application to a surface to provide antimicrobial and/or anti-odor activity comprising:
- a water and/or ethanol absorbent porous fabric material;
- and
- a composition distributed within the porous fabric material of at least two particulate solid reagents that react in the presence of water and/or alcohol to produce molecular iodine,
- the composition capable of providing a local concentration of at least 5 parts per million iodine in water or ethanol carried by the material when the material has 5% by weight of water and/or alcohol present in the water and/or alcohol with respect to the total weight of the water and/or alcohol absorbent porous fabric material;
- wherein at least one of the two particulate solid reagents is coated with a water-soluble, water dispersible or water-penetrable solid covering of water-soluble or water-dispersible particles that physically separates the two particulate solid reagents and the solid covering prevents ambient conditions of 50% relative humidity at 25° C. from causing more than 10% of the total reagents exposed to the ambient conditions from reacting in a twenty-four hour period.
