A disposable article is formed of an alkali-sensitive film or an alkali-disintegratable non-woven material and is adapted to dissolve in an alkali environment, which may be liquid, having a sufficiently high alkali pH value, say 7.5 or more. An example of such an article is the inner, next-to-body, liner of a disposable diaper which can be disposed of in a toilet bowl with contained body waste matter, the liner disintegrating so that it can be flushed away with the latter. If necessary, the pH alkali value of the water in the toilet bowl can be enhanced by a pH adjuster. Such disposable articles remove health and pollution risks. |
