Abstract
A bulky, water-disintegratable cleaning article is formed of water-disintegratable paper impregnated with 100% to 500% by weight of an aqueous agent. The water-disintegratable paper is a substantially water dispersible fibrous sheet containing a water soluble or swellable binder. The water-disintegratable paper has a great number of protrusions and depressions formed by embossing and has a basis weight of 30 to 150 g/m2. The bulky, water-disintegratable cleaning article has a thickness T1 of 1.0 to 3.0 mm under a load of 0.3 kPa and a thickness T2 of at least 0.9 mm under a load of 1.0 kPa.
