A composite material (4) for use as, or to provide, a disposable product, such as a nappy/diaper, said composite material being flushable and biodegradable and comprising an outer soluble layer (2) supporting a disintegratable and dispersable liquid absorbent layer (5), and a liquid impervious barrier (3) interposed between the soluble layer (2) and the absorbent layer (5), with the soluble layer and liquid impervious barrier being in synergistic relationship, whereby the composite material maintains its integrity during normal use but loses its integrity in response to the action of water when disposed of in a water flushing system. When the composite material is used, for example as a nappy/diaper, a skin-contacting cover which is also biodegradable covers the absorbent layer (5). |
