Description

Wet tissue, package of wet tissue, and chemical liquid for wet tissue Technical Field The present disclosure relates to wet tissues, packages of wet tissues, and medical solutions for wet tissues. Background Wet tissues comprising a nonwoven fabric and a chemical solution impregnated into the nonwoven fabric are known. As a preservative, for example, as disclosed in patent document 1, a preservative containing iodopropynyl butyl carbamate (IPBC) having high preservative property is known in the wet tissues. However, IPBC has a limited use country from the viewpoint of security and the like. This is because IPBC presents a concern for allergies caused by iodine. In addition, in order to improve the corrosion resistance of wet tissues, wet tissues containing a cationic surfactant having bactericidal properties are known. For example, patent document 2 discloses a liquid skin cleansing composition (claim 1) which contains (a) 0.005 to 3 wt% of a cationic surfactant, (B) 0.1 to 3 wt% of a nonionic surfactant, (C) 0.1 to 3 wt% of a water-soluble inorganic salt, and (D) 0.5 to 15 wt% of an alcohol. Patent document 2 discloses an example of a wet tissue in which a skin cleansing agent in the form of a composition impregnated into a support (claim 4) and a liquid skin cleansing agent composition are impregnated into a cellulose/rayon blended nonwoven fabric. Further, it is disclosed in paragraph [0012] of patent document 2 that "further, the nonionic surfactant used is preferably hydrophilic. Preferably, the nonionic surfactant has an HLB of 12 to 20, particularly preferably 15 to 20, and most preferably 17 to 19.5 based on Griffin. The effect of moderating the irritation of the cationic surfactant is particularly good by preparing the hydrophilic nonionic surfactant. ". Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2014-70044 Patent document 2 Japanese patent application laid-open No. 2001-187726 Disclosure of Invention Problems to be solved by the invention The wet wipe of patent document 2 contains a cationic surfactant having bactericidal properties as a preservative, and therefore has no concern about IPBC. As a result of the study by the present inventors, it has been found that when a nonwoven fabric containing hydrophobic fibers is impregnated with the liquid skin cleansing composition described in patent document 2 to form a package of wet tissues, particularly a package of pop-up wet tissues, the wet tissues are connected to each other through a water film of a chemical liquid, and a plurality of wet tissues can be easily taken out from the package at a time. Accordingly, it is an object of the present disclosure to provide a wet wipe that is difficult to remove multiple sheets at a time. Solution for solving the problem The present inventors have found a wet wipe characterized by comprising a nonwoven fabric containing hydrophobic fibers and a chemical solution impregnated in the nonwoven fabric, wherein the chemical solution contains (i) a cationic surfactant, (ii) a low HLB surfactant having an HLB of 3.0 to 7.0, and (iii). ADVANTAGEOUS EFFECTS OF INVENTION The wet wipes of the present disclosure are difficult to remove multiple sheets at a time. Drawings Fig. 1 is a view for explaining a package 1 of wet tissues according to embodiment 1. Fig. 2 is an end view at the II-II end of the package 1 of wet wipes. Fig. 3 is a view for explaining a plurality of wet tissues 9. Fig. 4 is an end view of package 1 of wet tissues according to embodiment 2. Detailed Description In particular, the present disclosure relates to the following schemes. Scheme 1 A wet wipe comprising a nonwoven fabric and a chemical solution impregnated into the nonwoven fabric, wherein the nonwoven fabric comprises hydrophobic fibers, and the chemical solution comprises: (i) A cationic surfactant; (ii) A low HLB surfactant having an HLB of 3.0 to 7.0, and (Iii) And (3) water. In the wet wipe, the medicinal liquid contains a cationic surfactant as a preservative. Since the liquid medicine containing the cationic surfactant is positively charged, the liquid medicine tends to be easily fused to the skin as compared with a liquid medicine containing a preservative other than the cationic surfactant, for example, iodopropynyl butylcarbamate (IPBC). On the other hand, when a chemical solution containing a cationic surfactant is used for wet tissues, it tends to be easy to take out a plurality of wet tissues at a time when taking out 1 wet tissue. Hereinafter, the "tendency to take out a plurality of wet tissues at once when taking out 1 wet tissue" is sometimes referred to as "tendency to take out a plurality of wet tissues" and the "ability to take out 1 wet tissue at once when taking out 1 wet tissue" is sometimes referred to as "1-sheet removability". In addition, the wet tissue uses a nonwoven fabric containing hydrophobic fibers as a base material of the wet tissue. A wet wipe compris
