Water-disintegrable paper having moisture retaining property and process for producing the same

Abstract

A water-disintegrable paper which can be used in the same way as the ordinary toilet paper and shows excellent water disintegrability, wiping out property, feel, and moisture retaining property is provided, the water-disintegrable paper comprising: a water-disintegrable body paper; one or more components selected from glycerol, diglycerol, polyethylene glycol having an average molecular weight in a desired range, sorbitol, propylene glycol, 1,3-butylene glycol, glycine betaine, pyrrolidone carboxylic acid, pyrrolidone carboxylic acid salt, maltitol, and sodium lactate, as a humectant; and one or more components selected from sodium carboxymethylcellulose, a starch, a denatured starch, guar gum polyvinyl alcohol, and polyacrylamide, as a dry paper strength additive. The water-disintegrable paper further comprises either polyethylene glycol having an average molecular weight in a desired range or an oil substance, or both the polyethylene glycol and the oil substance in addition to the above-mentioned components. The water-disintegrable paper can be produced with a low cost, does not need any special package or wrapping and shows no decrease in the paper strength.
