Enzyme Degradable System for Undergarments and Feminine Hygiene Articles

An enzyme-degradable system for an undergarment and a feminine hygiene article, the system comprising:

• an absorbent core, the core including at least one of the following:
• a cellulose, a wood pulp, a thermoplastic aliphatic polyester, and a superabsorbent polymer;
• an inner sheet comprising a plant based cellulosic nonwoven material;
• an outer sheet comprising the plant based cellulosic nonwoven material;
• a cellulose enzyme being integrated into the absorbent core, or the sheets, or both, the cellulose enzyme helping to at least partially decompose at least one of:
• the absorbent core, the inner sheet, and the outer sheet upon contact with urine;
• and
• at least one fastener disposed at a peripheral region of the inner and outer sheets, the fastener comprises a resilient, biodegradable material.

An enzyme-degradable system for an undergarment and a feminine hygiene article, the system consisting of:

• an absorbent core, the core including at least one of the following:
• a cellulose, a wood pulp, a cotton pulp, a thermoplastic aliphatic polyester, and a starch based superabsorbent polymer;
• an inner sheet comprising a plant based cellulosic nonwoven material, the inner sheet being a nonwoven material;
• an outer sheet comprising the plant based cellulosic nonwoven material;
• a cellulose enzyme including at least one of the following:
• DIS-1018 cellulose-AN, Aspergillus niger cellulase having an activity of 10,000-500,000 units per gram in a solid form or 10,000-500,000 units per gram in a liquid form, cellulases, amylases, pectinases, and an enzyme having an Enzyme Committee number from EC 3.2.1.1 to EC 3.2.1.203,
• the cellulose enzyme further comprising comprises a pH buffer, the pH buffer including at least one of the following:
• inorganic phosphates, diphosphates, triphosphates, pyrophosphates, organic phosphonates and polycarboxylic acids, salts of sodium, potassium, calcium, sodium phosphate, sodium triphosphate, Alanine, N,N-bis(carboxymethyl)-alanine, and N,N-bis(carboxymethyl)-glutamic acid,
• the cellulose enzyme further comprising at least one additive, the at least one additive including at least one of the following:
• adhesive removers, preservatives, glycerol, polyethylene glycol, alcohols with 2-8 carbons, sugars with 3-8 carbons, and sugar alcohols with 3-8 carbons,
• the cellulose enzyme being integrated into the absorbent core, or the sheets, or both, the cellulose enzyme helping to at least partially decompose at least one of:
• the absorbent core, the inner sheet, and the outer sheet upon contact with urine;
• and
• at least one fastener disposed at the peripheral region of the inner and outer sheets, the at least one fastener comprising a resilient, biodegradable material.
