Wound care coverings include a pad comprising a pad material, a lactate-based enzyme crosslinked with the pad material by a crosslinker, and a dye that changes color when H.sub.2O.sub.2 is present. In examples, an enzyme layer comprises a pad material crosslinked with a sugar-based enzyme by a crosslinker, a sugar-containing layer comprises a sugar in a hydrogel, and a rupturable barrier is between the enzyme layer and sugar-containing layer. In examples, a first enzyme layer comprises a first pad material, a lactate-based enzyme and a dye that changes color when H.sub.2O.sub.2 is present; a second enzyme layer comprises a second pad material crosslinked with a sugar-based enzyme by a second crosslinker; a sugar-containing layer comprises a sugar in a hydrogel, where the second enzyme layer is between the sugar-containing layer and the first enzyme layer; and a rupturable barrier is between the second enzyme layer and the sugar-containing layer.

Disclosed is a dissolvable, gel-forming film, and methods for its use, comprising a water-soluble cellulose ether, a hydrophilic rheological modifying agent, and an active proteolytic enzyme or other drug substance. The gel-forming film has a water content of less than 15% w/w and is capable of forming a hydrogel when contacted with water or other aqueous medium. The disclosed films achieve delivery of stable proteolytic enzymes to the desired site of action in a manner that provides uniform delivery of the enzymes.

A biodegradable disposable diaper includes an inner layer comprising a soft, non-woven fabric, the inner layer for resting against a wearer's skin and allowing the passage of bodily waste fluids, a middle layer comprising superabsorbent polymer for absorbing and retaining the bodily waste fluids, an outer layer comprising a liquid impermeable membrane, the outer layer for restricting the passage of bodily waste fluids, and a frangible capsule, dispenser or packet containing a substance comprising mycelium, fungal spores and/or enzymes configured for using bodily waste to grow and degrading the biodegradable disposable diaper in a disposal environment, the frangible capsule, dispenser or packet further for allowing the deposition of the substance into the diaper at the time of disposal. A substance configured for using bodily waste to grow and degrading a biodegradable disposable diaper in a disposal environment, the substance configured for deposition onto the diaper.

Methods of entrapping enzymes in chitosan matrices using mild conditions, such as methods that are compatible with the entrapment of acid-sensitive and/or heat sensitive enzymes, are described. The methods can provide biocatalytic materials with high chitosan to enzyme mass ratios where one or more enzymes can remain active and stably entrapped in the chitosan matrix for many months and/or after repeated washings. Also described are materials including a solid chitosan matrix having at least one enzyme stably entrapped therein, including fabrics, textiles and other flexible materials at least partially coated with one or more layer of the solid chitosan matrix having at least one enzyme stably entrapped therein and the use of the materials as biocatalyst systems, for example in biogas upgrading and other applications.

The present invention relates to a process of enzymatic degradation of an absorbent structure, the absorbent structure being suitable for providing an absorbent core of a hygiene article, wherein the process comprises the step of contacting the absorbent structure with a solution comprising enzymes; wherein the absorbent structure comprises a polysaccharide superabsorbent polymer, such as a cellulose-based or a starch-based superabsorbent polymer.
