  • Patent number: 10792389
    Abstract: 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 plastic—PLA), and a superabsorbent polymer (SAP). The inner and outer sheets comprise a plant based cellulosic nonwoven material. The cellulase enzyme decomposes the absorbent core, the inner sheet, and the outer sheet upon contact with a bodily fluid. The cellulase 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.
