PROBLEM TO BE SOLVED: To provide drug solution for wet tissue and wet tissue which do not contain paraben and have excellent takeout smoothness regardless of larger content of water than conventional products.SOLUTION: There is provided drug solution for wet tissue which does not contain paraben, and in which a product of the film thickness of the drug solution and the surface tension of the drug solution measured by the following measuring method is 810 (μm mN/m) or more. As a film thickness measuring method of the drug solution, after dripping 0.03 ml of the drug solution onto a preparation, another preparation having the same size is silently placed and laminated on the preparation. After the preparations are left to stand for 30 seconds, the preparations are observed in a magnified manner by a microscope from an immediate lateral direction, and the film thickness of the drug solution interposed between the preparations is measured. |
