Abstract
An article or material is applied to the environment of the body of an animal (including humans) to provide both absorbency and antimicrobial activity. The article or material may comprise a water absorbent material; and a composition that reacts with water to produce molecular iodine. The composition provides a local concentration (in the water) of at least 10 parts per million iodine in water 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. The material may be a flowable material, or the article may be diaper, sanitary pad, bandage, adhesive pad or wrap for an animal.
Claims18
A flowable particle blend of at least three separate and distinct particles for application to an environment that is a habitat for an animal, the granular composition providing both absorbency and antimicrobial activity comprising:
- a) a granular water absorbent solid carrier material carrier comprising superabsorbent polymer in the form of particles, granules or flakes;
- and
- b) a reactive composition;
- the reactive composition consisting essentially of at least two separate particles as a first particle comprising CuSO4 reagent and a second particle comprising KI reagent, the first particle and the composition of the second particle reacting with each other in the presence of water to produce molecular iodine, each of the first particles and the second particles being carried by a water absorbent solid carrier material so that application of aqueous liquid equal to 100% by weight of the reactive composition to the composition will cause the reagents of the at least two separate particles to be combined by the aqueous liquid and react with each other;
- and wherein the two separate particles and the water absorbent carrier are granular, the reactive composition providing a local concentration of at least 10 parts per million iodine in the aqueous liquid applied to the granular composition when the granular composition has 5% by weight of aqueous liquid present in the water absorbent solid carrier material with respect to the total weight of the water absorbent solid carrier material.
A flowable particulate composition for application to a stall or cage for an animal, the composition providing both absorbency and antimicrobial activity comprising:
- a) a water absorbent solid carrier material carrier comprising superabsorbent polymer in the form of particles, granules or flakes;
- and
- b) an at least two particle reactive composition;
- the reactive composition comprising at least two separate particles as a first particle comprising CuSO4 reagent and a second particle comprising KI reagent, the first particle and the composition of the second particle reacting with each other in the presence of water to produce molecular iodine, each of the first particles and the second particles being carried by the water absorbent solid carrier material so that application of aqueous liquid equal to 100% by weight of the reactive composition to the reactive composition will cause the reagents of the at least two separate particles to be combined by the aqueous liquid and react with each other;
- and wherein the two reactive particles provides a local concentration of at least 10 parts per million iodine in the aqueous liquid applied to the flowable particulate composition when the flowable particulate composition has 5% by weight of aqueous liquid present in the water absorbent solid carrier material with respect to the total weight of the water absorbent solid carrier material.
A flowable multiple particle and separate particle blend for application to an environment that is a habitat for an animal, the flowable multiple particle and separate particle blend providing both absorbency and antimicrobial activity comprising:
- a) a water absorbent solid carrier material carrier comprising superabsorbent polymer;
- and
- b) a reactive two particle composition;
- the reactive composition comprising at least two separate particles as a first particle comprising CuSO4 reagent and a second particle comprising KI reagent, the first particle and the composition of the second particle reacting with each other in the presence of water to produce molecular iodine, each of the first particles and the second particles being carried by a water absorbent solid carrier material so that application of aqueous liquid equal to 100% by weight of the reactive composition to the flowable multiple particle and separate particle blend will cause the reagents of the at least two separate particles to be combined by the aqueous liquid and react with each other;
- and wherein the two separate particles and the water absorbent carrier are granular, the reactive composition providing a local concentration of at least 10 parts per million iodine in the aqueous liquid applied to the reactive composition when the flowable multiple particle and separate particle blend has 5% by weight of aqueous liquid present in the water absorbent solid carrier material with respect to the total weight of the water absorbent solid carrier material.
