Abstract

A water soluble strip that includes a carrier film that include water soluble polymer, one or more actives and one or more agents such as heat forming agent and/or degrading accelerator. The water soluble strip can optionally include other additives. The actives includes antimicrobial agent, cleaning agent and/or surfactant. The water soluble strip can include other materials. The heat forming agent and/or degrading accelerator, when used, are designed facilitate in degrading or dissolving the water soluble strip and/or increase the activity of the one or more actives. The water soluble film can be used for a variety of applications such as a hard surface cleaning strip, dishwashing strip, laundry cleaning strip, stop removing strip, drain unclogging strip, toilet bowl cleaning strip and the like. The water soluble strip eliminates the need to purchase and store numerous containers and/or heavy containers of cleaner that take up large amounts of shelf space.

Claims (64)

1. A water soluble strip that includes a earner film, one or more actives and one or more agents selected from the group consisting of heat forming agent and degrading accelerator, said carrier film including water soluble polymer, said active including one or more agents selected form the group consisting of antimicrobial agent and surfactant, wherein said heat forming agent is fully or partially embedded in said carrier film said water soluble polymer formulated cause said carrier film to dissolve in water and release said one or more actives contained in said carrier film as said carrier film dissolves in the water.

2. The water soluble strip as defined in claim 1 , wherein said water soluble polymer includes one or more polymers selected from the group consisting of cellulose, hydroxypropyl cellulose, carboxymethylcellulose, sodium alginate, polyvinylalcohol, and hydroxyethylcellulose.

3. The water soluble strip as defined in claim 1 , wherein said heat forming agent constitutes about 2-45 weight percent of said water soluble strip, said heat forming agent including one or more materials selected form the group consisting of electrolyte salt, lime, metal, activated carbon, metal oxide, polyalkyleneamine, polyalkyleneimine, polyvinyl amine and zeolite.

4. The water soluble strip as defined in claim I, wherein said degrading accelerator constitutes about 0.01-20 weight percent of said water soluble strip, said degrading accelerator including one or more materials selected form the group consisting of alkali metal carbonates, alkali metal hydrogen carbonates and ammonium carbonates.

5. The water soluble strip as defined in claim 3 , wherein said degrading accelerator constitutes about 0.01-20 weight percent of said water soluble strip, said degrading accelerator including one or more materials selected form the group consisting of alkali metal carbonates, alkali metal hydrogen carbonates and ammonium carbonates.

6. The water soluble strip as defined in claim 1 , wherein one or more antibacterial agents is fully or partially embedded in said carrier film.

7. The water soluble strip as defined in claim 1 , wherein said water soluble strip is a roll of strip that includes one or more perforations or markings that are used to designate a recommend strip length for a particular purpose of said water soluble strip.

8. The water soluble strip as defined in claim 1 , including a water tight and air impermeable package that includes one or more of said water soluble strips, said package designed to inhibit or prevent exposure of said water soluble strip to oxygen and water until said package is opened.

9. The water soluble strip as defined in claim 1 , including one or more additives, said additives selected form the group consisting of thermochromic agent, dye, pigment, plasticizer, defoamer, thickener, anti-dye transfer agent, fragrance, preservative, solvent, opacifier, clarifier and humectant.

10. The water soluble strip as defined in claim 1 , further comprising a water soluble adhesive.
