PROBLEM TO BE SOLVED: To provide reasonably-priced wet tissue paper quite safe to a human body and having no odor or color during use by impregnating paper of unwoven cloth or a plant family using a reproduced cellulose fiber with chitosan organic acid water solution and benzoic acid salt. SOLUTION: Chitosan organic acid water solution has good resistance to bacteria but not so effective for mildew. On the other hand, a benzoic acid salt, especially the long time use of sodium salt shows that it is effective as a foodstuff additive for preventing the occurrence of mildew. Thus, by impregnating paper made of nonwoven fabric or a plant family mainly using a reproduced cellulose fiber with chitosan organic acid water solution and benzoic acid salt, wet tissue paper is provided, which gives no damage to a human body and no unpleasant feeling in vision, olfaction or gustatory sense in a using state. In this case, preferably, the wet tissue paper contains solid chitosan of 0.05 to 1.0wt.% and benzoic acid salt of 0.05 to 0.1wt.%. |
