Title
(EN) BIODEGRADABLE INCONTINENCE DEVICE
(FR) DISPOSITIF BIODEGRADABLE D'INCONTINENCE
Abstract
(EN)
The present invention concerns a biodegradable incontinence device such as a diaper. The incontinence device has biodegradability enhancer granules (100) containing an enzyme such as cellulase or hemicellulase embedded therein. The outer layers (60) of the device are preferably made of a biodegradable material such as treated paper or rayon.
(FR)
Cette invention concerne un dispositif biodégradable d'incontinence par exemple une couche. Le dispositif comporte des granulés (100) permettant d'améliorer la biodégradabilité, lesdits granulés incorporant une enzyme telle que la cellulase ou l'hemicellulase. Les couches extérieures (60) du dispositif sont faites de préférence à partir d'un matériau biodégradable tel que le papier traité ou la rayonne.
