Abstract: The invention relates to an environmentally-friendly disposable absorbent article. At least half of the constituent materials used in the disposable absorbent article contain biodegradable compounds and/or compounds of natural origin.

Abstract: The present invention relates to a disposable absorbent article such as a sanitary napkin or a panty-liner, basically comprising an upper layer, a lower layer and an absorbent core of a design suitable to be used with tanga-type underwear, disposed between both layers; the core has a front section and a back section and wings or lateral projections preferably extending along the entire length of the absorbent core.

Abstract: A disposable diaper is described in which the absorbent core's material is distributed in such a way that three zones are made inside of it" one of liquid reception, a zone of distribution-storage, and finally an anti-leakage zone. The reception zone is placed where generally the user discharges urine while using the diaper. This zone is less dense and has a lower specific gravity than the distribution-storage zone that fully surrounds it, in such way that when liquid flows in the reception zone it is immediately absorbed and flows towards the distribution-storage zone, which will distribute the liquid to every zone of the diaper and there it will remain until the diaper is disposed, since when liquid reaches the anti-leakage zone fluid flow is drastically stopped because this zone has lower density than the distribution-storage zone and the liquid will not flow towards it due to the increased size of the capillary radius.
