Description

[Technical Field]

[0001] The present invention relates to a wipe-off disinfectant cleaning composition that does not require rinsing with water, and a disinfectant cleaning method for an object to be disinfected using the same. [Background technology]

[0002] Generally, commercially available laundry detergents for clothing or detergents specifically for athletic shoes are used to clean athletic shoes, sneakers, and the like.

[0003] On the other hand, these detergents are generally used in water, so sneakers must be soaked in the detergent solution, scrubbed with a brush, and then rinsed with water to remove the detergent ingredients and dirt.However, this can cause problems such as damage to the fabric due to scrubbing, and it takes a long time for the sneakers to dry after rinsing, making them unable to be worn immediately.

[0004] Therefore, there is a certain demand for cleaning agents that can be used for cleaning without the need for rinsing with water. For example, Patent Document 1 describes a cleaning sheet that can clean and disinfect dirt from shoes without the need for rinsing with water.

[0005] In addition, anionic surfactants are useful for exerting cleaning power against dirt on shoes, such as dust and mud stains, while cationic surfactants are useful for exerting disinfecting properties. Patent Document 2 describes a disinfecting cleaning composition that uses both of these surfactants. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2021-70815 [Patent Document 2] Japanese Patent Publication No. 2020-147656 Summary of the Invention [Problem to be solved by the invention]

[0007] However, when both anionic surfactants and cationic surfactants are blended, it can be difficult to achieve both cleaning power and disinfecting performance due to the formation of an anionic-cationic complex, etc. Furthermore, by its nature, wipe-off cleaning is a cleaning method in which a relatively high concentration of cleaning solution is likely to come into contact with the hands and fingers, and generally, the stronger the cleaning power, the stronger the skin irritation tends to be, which can cause rashes and sores on the hands and fingers of users.

[0008] Therefore, the present invention aims to provide a wipe-off disinfectant cleaning composition that does not require rinsing with water, which has both good cleaning power and disinfecting performance and is low in skin irritation, even when it contains both an anionic surfactant and a cationic surfactant. [Means for solving the problem]

[0009] In view of the above problems, the present inventors have conducted extensive research and have discovered a wipe-off disinfectant cleaning composition that, by using a combination of specific surfactants, does not require rinsing with water, has sufficient cleaning power and disinfecting performance, and is also low in skin irritation, thereby completing the present invention.

[0010] That is, the present invention is as follows. (1) a cationic surfactant containing two or more hydroxyalkyl groups having 2 to 6 carbon atoms; an α-olefin sulfonate type anionic surfactant; A nonionic surfactant, A wipe-off disinfectant cleaning composition comprising: (2) The wipe-off disinfectant cleaning composition according to (1), which has a surface tension of 24.0 to 30.0 mN / m. (3) A disinfecting and cleaning product in which the wipe disinfecting and cleaning composition according to (1) or (2) is contained in a container for dispensing or spraying. (4) The disinfecting and cleaning product according to (3) further comprising a wiping cloth. (5) A disinfecting and cleaning product according to (3) or (4), wherein the container for discharging is a container that forms foam upon discharging. (6) A method for disinfecting and cleaning an object to be disinfected, characterized in that the wipe disinfectant cleaning composition described in (1) or (2) is ejected or sprayed onto a wiping cloth and wiped onto the surface of the object to be disinfected and cleaned. (7) A method for sterilizing and cleaning an object to be sterilized according to (6), wherein the object to be sterilized and cleaned is made of one or more materials selected from the group consisting of synthetic leather, natural leather, linen, cotton, nylon, vinyl chloride, nubuck, rubber and suede.

The pH of this disinfectant cleaning composition was approximately 7. The content of each ingredient in the table is a value converted from the active ingredient content. These wipe-off disinfectant cleaning compositions (test chemical solutions) were evaluated for detergency, skin irritation, and disinfecting performance using the following methods. Furthermore, the surface tension of each composition was measured using the pendant drop method (measuring instrument: Kyowa Interface Science Co., Ltd.; simple contact angle meter DMe-211). These results are also shown in Table 1.

[0048] [Table 1]

[0049] (Cleaning power test) (1) Synthetic leather with carbon black attached as a simulated stain was used as the test cloth. (2) The stain lightness of the test cloth was measured using a spectrophotometer (Konica Minolta, CM-700d). The amount of stain attached was adjusted so that the lightness Ls was 25±5. The lightness L0 of the synthetic leather before attachment was also measured. (3) Next, the test solution was poured into a commercially available foamer pump. The test cloth was fixed to a Gardner abrasion tester (manufactured by BYK). One pump of the test solution was applied to the wiping sponge, and the cloth was moved back and forth 10 times at a pace of 30 beats per minute. (4) Brightness L of the test cloth after washing w The cleaning rate D (%) was calculated from the change in brightness before and after wiping using the following formula.

[0052] (Skin irritation) Skin irritation was estimated from the following protein denaturation rate test. Specifically, 0.053% ovalbumin (OVA) was dissolved in 500 mL of 0.05 M phosphate buffer (pH 7.0). 1.5 g of each test drug solution was mixed with 28.5 g of OVA solution and allowed to stand overnight at 40°C. The amount of unmodified and unmodified OVA was separated by GPC, and the OVA denaturation rate was calculated from the peak height of the unmodified OVA.

[0054] (sterilization performance) <Test Method> (a) Preparation of test bacterial solution After culturing Staphylococcus aureus (NBRC12732) as the test bacteria, it was suspended and dispersed in 1 / 2 nutrient liquid medium to obtain a bacterial concentration of 1 x 10 8 ~9×10 8 The test bacteria solution was prepared using a 1 / 2 nutrient liquid medium so that the concentration would be cfu / mL, and mixed with an equal amount of a 3% by mass aqueous solution of bovine serum albumin to obtain a test bacteria solution. (b) Inoculation of test bacterial solution A sterilized stainless steel disk with a diameter of 20 mm, a thickness of 1 mm, and a surface grade of 2B was placed in a glass petri dish, and 0.01 mL of the test bacteria solution was inoculated and spread on the surface of the disk using a micropipette. The glass petri dish was left uncovered at 25°C, and after confirming that the test bacteria solution had dried, 0.1 mL of the sample (each of the disinfectant cleaning compositions prepared above) was immediately inoculated into 3.14 cm of the surface of the 20 mm diameter stainless steel disk using a micropipette. 2 After 5 minutes, a certain amount of SCDLP medium was added to inactivate the disinfecting ability of the disinfectant cleaning composition.
