発明の概要
　この種の清拭材では、含有させた陽イオン界面活性剤が対象物に適用されて殺菌効果などを付与することが期待できる。しかし、薬液に所定量の陽イオン界面活性剤を配合しても、対象物に適用される陽イオン界面活性剤の量は低下する傾向がある。これは不織布に薬液を含浸させた直後から数日かけて、陽イオン界面活性剤の不織布への吸着が経時的に進むことが原因である。更に、陽イオン界面活性剤と併用することで、洗浄性や抗菌性向上が期待される非イオン界面活性剤を配合した薬液についても、陽イオン界面活性剤と連動するように非イオン界面活性剤の吸着が進行するという課題を生じる。 Outline of the Invention In this kind of cleaning material, it can be expected that the contained cationic surfactant is applied to the object to impart a bactericidal effect or the like. However, even if a predetermined amount of the cationic surfactant is added to the chemical solution, the amount of the cationic surfactant applied to the object tends to decrease. This is due to the fact that the adsorption of the cationic surfactant to the non-woven fabric progresses over time over several days immediately after the non-woven fabric is impregnated with the chemical solution. Furthermore, even for chemicals containing nonionic surfactants, which are expected to improve detergency and antibacterial properties when used in combination with cationic surfactants, nonionic surfactants are linked with the cationic surfactants. The problem arises that the adsorption of

発明を実施するための形態
　本発明者らは、陽イオン界面活性剤及び非イオン界面活性剤を配合した水性組成物を不織布に担持させても期待される殺菌効果が得られない原因を究明した結果、陽イオン界面活性剤及び非イオン界面活性剤が不織布に吸着することで、対象物に接触する濃度が低下することが原因であることを明らかにした。そして陽イオン界面活性剤及び非イオン界面活性剤に、（ｂ）成分である特定のイオンを含む無機塩を特定条件で用いることで、陽イオン界面活性剤及び非イオン界面活性剤の不織布への吸着を抑制できることを見出した。 Embodiments for Carrying Out the Inventions The present inventors have investigated the reason why the expected bactericidal effect cannot be obtained even if an aqueous composition containing a cationic surfactant and a nonionic surfactant is supported on a non-woven fabric. As a result, it was clarified that the cause was that the concentration of the cationic surfactant and the nonionic surfactant adsorbed on the non-woven fabric was reduced in contact with the object. Then, by using an inorganic salt containing a specific ion as the component (b) as the cationic surfactant and the nonionic surfactant under specific conditions, the cationic surfactant and the nonionic surfactant can be added to the non-woven fabric. It was found that adsorption can be suppressed.

　（ａ）成分と共存時の殺菌性及び対象表面への濡れ性の観点から、（ｃ）成分は、ＨＬＢが１２．５未満の非イオン界面活性剤が好ましい。すなわち、本件の水性組成物は、（ｃ）成分として、ＨＬＢが１２．５未満の非イオン界面活性剤を含有することが好ましい。ここで、（ｃ）成分のＨＬＢは、ポリオキシエチレン基を有する非イオン界面活性剤の場合には、下記一般式（Ｉ）で表されるグリフィン（Griffin）法により求められる。

That is, the aqueous composition of the present invention preferably contains a nonionic surfactant having an HLB of less than 12.5 as the component (c). Here, the HLB of the component (c) is determined by the Griffin method represented by the following general formula (I) in the case of a nonionic surfactant having a polyoxyethylene group.
HLB value = [(Molecular weight of polyoxyethylene group portion of component (c)) / (Molecular weight of component (c))] × 20 (I)
The molecular weight of the polyoxyethylene group portion of the component (c) shall be calculated using the value of the average number of moles of the polyoxyethylene group added.
　ＨＬＢが低い非イオン界面活性剤、例えばＨＬＢが１２．５未満の非イオン界面活性剤は、上記の通り、（ａ）成分と共存時の殺菌性及び対象表面への濡れ性の観点から好ましい成分であるが、陽イオン界面活性剤とともに使用すると不織布に吸着しやすい傾向を示す。本発明では、そのような非イオン界面活性剤についても不織布への吸着を抑制できることから、低ＨＬＢの非イオン界面活性剤を用いることで期待される効果が対象物で十分に発揮される。 A nonionic surfactant having a low HLB, for example, a nonionic surfactant having an HLB of less than 12.5 is a preferable component from the viewpoint of bactericidal property when coexisting with the component (a) and wettability to the target surface, as described above. However, when used in combination with a cationic surfactant, it tends to be easily adsorbed on the nonionic surfactant. In the present invention, since the adsorption of such a nonionic surfactant to the non-woven fabric can be suppressed, the expected effect by using the low HLB nonionic surfactant is sufficiently exhibited in the object.
　ＨＬＢが１２．５未満の非イオン界面活性剤は、（ａ）成分と共存時の殺菌性及び対象表面への濡れ性の観点から、好ましくは８以上、そして、１２．５未満、好ましくは１２以下、より好ましくは１１以下、更に好ましくは１０以下である。 A nonionic surfactant having an HLB of less than 12.5 is preferably 8 or more, and less than 12.5, preferably 12 from the viewpoint of bactericidal property when coexisting with the component (a) and wettability to the target surface. Below, it is more preferably 11 or less, still more preferably 10 or less.
　ＨＬＢが１２．５未満の非イオン界面活性剤は、前記一般式（ｃ１）で表される非イオン界面活性剤であって、ＨＬＢが１２．５未満である非イオン界面活性剤が好ましい。一般式（ｃ１）中、Ｒ１ｃ以外の他の化学構造が同じであれば、Ｒ１ｃの炭素数が大きくなる程ＨＬＢの値は低くなる。また、一般式（ｃ１）中、ＡＯ基は、エチレンオキシ基を含む炭素数２以上４以下のアルキレンオキシ基であり、エチレンオキシ基はプロピレンオキシ基よりもＨＬＢの値を高くさせる。また、一般式（ｃ１）中、ｎ以外の他の化学構造が同じであれば、ｎの数が大きくなる程ＨＬＢの値は高くなり、小さくなる程ＨＬＢの値は低くなる。 The nonionic surfactant having an HLB of less than 12.5 is a nonionic surfactant represented by the general formula (c1), and a nonionic surfactant having an HLB of less than 12.5 is preferable. In the general formula (c1), if the chemical structures other than R 1c are the same, the HLB value decreases as the carbon number of R 1c increases. Further, in the general formula (c1), the AO group is an alkyleneoxy group having 2 or more and 4 or less carbon atoms including an ethyleneoxy group, and the ethyleneoxy group has a higher HLB value than the propyleneoxy group. Further, in the general formula (c1), if the chemical structures other than n are the same, the larger the number of n, the higher the HLB value, and the smaller the number, the lower the HLB value.

The molar ratio to the amount (content of divalent ion) / (content of component (c)) is preferably 0.4 or more, more preferably 0.5 or more, still more preferably 0.9 or more, still more. It is preferably 2.0 or more, more preferably 4.0 or more, and preferably 40 or less, more preferably 20 or less.
