[0035] Second embodiment A disinfectant spray according to a second embodiment of the present invention will be described below. The disinfectant spray of this embodiment is a container with a trigger filled with the disinfectant composition of the first embodiment.

The disinfectant composition contains an alcohol, an iodine-based agent, and an anionic surfactant, which provides a suitable disinfecting effect, and the disinfectant composition has an alcohol content of more than 0.495% by mass and less than 9.9% by mass, which provides good foaming.
[0039] The effects of the disinfectant composition of this embodiment will be described. (1) By containing alcohol, an iodine-based agent, and an anionic surfactant, the disinfectant composition has a suitable disinfecting effect. Specifically, the disinfectant composition has a suitable disinfecting effect against microorganisms such as mold, bacteria, and viruses including corona. In addition, by having an alcohol content of more than 0.495% by mass and less than 9.9% by mass, the disinfectant composition foams well. Therefore, dripping can be suppressed when used as a disinfectant spray.

[0040] (2) The anionic surfactant contains a polyoxyalkylene alkyl ether sulfate, and the content of the polyoxyalkylene alkyl ether sulfate is more than 0.1% by mass and not more than 1% by mass. This can prevent the disinfectant composition from stagnating, improving the appearance of the disinfectant composition.
[0041] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction. The disinfectant composition of the present embodiment may further contain preservatives, fragrances, colorants, etc., within limits that do not impair the effects of the present invention. EXAMPLES
[0042] 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.
[0043] 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.
[0044] By the above procedure, the disinfectant composition of Example 1 shown in Table 1 was prepared. The above blending may be carried out in any suitable order. The disinfectant compositions of Examples 2 to 5 and Comparative Examples 1 and 2 were prepared in the same manner as in Example 1, using the components shown in Table 1. The disinfectant compositions of Examples 1 to 5 and Comparative Examples 1 and 2 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.
[0045] [Table 1] (Evaluation test) The foaming property was evaluated for the disinfectant compositions of Examples 1 to 5 and Comparative Examples 1 and 2. The evaluation criteria for foaming property are shown below.
[0046] (Foamability) 1 g of each disinfectant composition was placed in a test tube and shaken up and down 30 times in 10 seconds to generate foam. After shaking, the mixture was left to stand, and the state of the foam immediately after standing and after standing for 1 minute was visually observed. The foaming property was evaluated according to the following evaluation criteria.
[0047] ·Foamability evaluation criteria ◎ (Good): Foaming was observed immediately after leaving the mixture to stand, and foaming was maintained even after leaving the mixture to stand for 1 minute. 〇 (Acceptable): Foaming was observed immediately after leaving the sample to stand, and after leaving the sample for 1 minute, the foaming decreased slightly but was maintained. × (bad): Insufficient foaming was not observed immediately after standing. The results in Table 1 show that the disinfectant composition of the present invention had good foaming ability.
[0048] In addition, 140 g of the disinfectant compositions of Examples 1 to 5 were left in an environment of -5°C for 15 hours, and the presence or absence of stagnation was visually observed. Stagnation was observed in the disinfectant composition of Example 4, but not in the disinfectant compositions of Examples 1 to 3 and 5. The term "stagnation" refers to a cloudy state in which the components of the disinfectant composition are separated.
