An enzyme-degradable system for undergarments and feminine hygiene articles works to decompose the undergarments and feminine hygiene articles upon being triggered by bodily fluids, such as urine. The undergarment or feminine hygiene article comprises an absorbent core, an inner sheet of biodegradable material, and an outer sheet of biodegradable material. The core includes at least one of the following: a cellulose material, a wood pulp, a biodegradable and bioactive thermoplastic aliphatic polyester derived from renewable resources (polylactic acid plasticPLA), and a superabsorbent polymer (SAP). The inner and outer sheets comprise a plant based cellulosic nonwoven material. The cellulose enzyme decomposes the absorbent core, the inner sheet, and the outer sheet upon contact with a bodily fluid. The cellulose enzyme may include DIS-1018 Cellulose-AN, a pH buffer, and additives. Fasteners made from a resilient, biodegradable material help secure the undergarments and feminine hygiene articles to the body.

Disclosed is a moisture-retaining body having a water-absorbing surface, having a structure in which, from a water-absorbing surface side, a water-permeable layer having water disintegrability and water permeability, a moisture-retaining layer having water disintegrability, water absorbability, and water retainability, a water-repellent layer including a water-soluble film and dots of a dot-like water-repellent resin with a diameter of 5 ?m to 150 ?m dispersed on a surface side of the water-soluble film facing the moisture-retaining layer, and a support layer having water disintegrability are sequentially laminated, as a moisture-retaining body which is quickly dissolved or decomposed by coming into contact with a large amount of water when dumped in a flush toilet or the like while being prevented from being dissolved or decomposed by retained moisture.

Systems, apparatus, and methods are described for delivering a therapeutic substance to the tympanic membrane of an ear of a subject, including a reservoir configured to contain the therapeutic substance and a delivery interface by which the therapeutic substance is delivered to the tympanic membrane.

A sanitary absorbing construction to be used by children and infants to hold and restrain liquid and solid dejections, which article is conventionally called napkin, of a single-use or disposable kind, made by combining different raw synthetic or natural materials, comprising apple waste materials, being industrially transformed into composite sub-layers which are assembled together to form articles having different shapes depending on technical or aesthetical requirements, and being biodegradable either before or after their use, when released into the environment, and being compostable or able to be transformed to into organic amending materials, when properly collected and separated or mixed with other organic domestic waste materials and then let into the compost cycle, per se or together with organic waste materials either from foodstuff or not.

An absorbent article (1) comprising: a liquid permeable topsheet (2), a liquid impermeable backsheet (3), and an absorbent core (4) positioned between said topsheet (2) and backsheet (3), wherein the absorbent core (4) comprises an absorbent material (5), said absorbent material comprising a mixture, or blend, of cellulose fibers (5a) and superabsorbent material (5b), characterized in that the superabsorbent material comprises biodegradable superabsorbent material (bioSAP) that has a first color in dry state and a second color in wet state, and in that first color and the second color has a CIELab color space difference (E) of at least 2 as measured according to the test method herein.
