[0040] In the following, examples will be given in order to more specifically explain the configuration and effects of the present invention, but the present invention is not limited to these examples. Ion-exchanged water was placed in a beaker, and while stirring at 150 rpm using a known stirrer, a pH adjuster, a chelating agent, ethanol with a concentration of 99% as alcohol, and polyoxyethylene (2) lauryl ether sodium sulfate as an anionic surfactant were added in this order. Note that "(2)" in the above polyoxyethylene (2) lauryl ether sodium sulfate refers to the number of moles of ethoxy groups added.

[0041] Furthermore, a nonionic surfactant, an alkylamidopropyl betaine having an alkyl group with 8 to 18 carbon atoms as an amphoteric surfactant, povidone iodine as an iodine-based drug, and an iodine stabilizer were added to the beaker in this order and mixed uniformly.

[0042] By the above procedure, the disinfectant composition of Example 1 shown in Table 1 was prepared. The above blending may be carried out in the appropriate order. The disinfectant composition of Comparative Example 1 was prepared in the same manner as in Example 1, using the components shown in Table 1. The disinfectant compositions of Example 1 and Comparative Example 1 were configured as transparent liquids. The values ​​in Table 1 refer to the content (mass%) when the entire disinfectant composition including ion-exchanged water is taken as 100 mass%. The alcohol content (mass%) in the disinfectant composition was calculated by calculating the amount of alcohol contained in 99% ethanol, and the content (mass%) in the disinfectant composition was obtained.

[0043] [Table 1] (Evaluation test) The presence or absence of stagnation was evaluated for the disinfectant compositions of Example 1 and Comparative Example 1. The evaluation criteria for each evaluation test are shown below.

[0044] (Presence or absence of sediment) 140 g of each disinfectant composition was left in an environment of -5°C for 15 hours, and the presence or absence of stagnation was visually observed. Evaluation was performed according to the following evaluation criteria. Note that "stagnation" refers to a state in which each component of the disinfectant composition is separated and becomes cloudy.

[0045] ·Evaluation criteria for the presence or absence of sedimentation 〇 (Good): No sedimentation observed × (bad): If sedimentation is observed In addition, 1 g of the disinfectant composition of Example 1 and Comparative Example 1 was placed in a test tube and shaken up and down 30 times in 10 seconds to generate foam. After shaking, the tube was left to stand, and the state of the foam immediately after standing and after one minute was visually observed. In both Example 1 and Comparative Example 1, foaming was observed immediately after standing, and foaming was maintained even after one minute of standing.

[0046] From the results in Table 1, it can be seen that the present invention was able to suppress stagnation of the disinfectant composition, and also had good foaming properties.
