It has become.

  In general, cleaning agents for hard surfaces have compositions suitable for each of them in order to remove different stains to be treated, such as bathrooms, kitchens and floors. For example, kitchen cleaners used around kitchens such as ovens, ovens, walls and floors around the range, and exhaust fans are used to remove oil stains that have been altered by the action of heat, sunlight, oxygen in the air, etc. A cleaning agent containing an activator, a solvent, an alkali agent and the like is used. Also, as bathroom cleaners used in bathrooms such as bathtubs, bathroom walls and floors, metal soaps, especially detergents containing detergents, metal ion sequestering agents, etc., are used to remove dirt from fatty acid calcium salts. The agent is used.

  In addition, when cleaning hard surfaces such as toilets, bathrooms, and kitchen surroundings, it is desired that excellent bactericidal properties be obtained along with detergency. For this reason, a sterilizing component is blended with a hard surface cleaning agent.

  In Patent Document 1, a liquid detergent composition for hard surfaces containing a cationic surfactant, an amphoteric surfactant, and a specific organic compound such as benzyl alcohol under a predetermined condition is generated in a bathroom or the like. It is disclosed that stains exhibiting color and / or red can be effectively removed.

  Patent Document 2 discloses a low-residue antibacterial cleaning composition containing a specific organic carboxylic acid and a hardly soluble monovalent solvent selected from aliphatic alcohols and glycol ethers under predetermined conditions.

  Patent Document 3 discloses a liquid disinfecting composition containing an effective amount of a disinfecting substance and a specific poly (alkylene glycol) alkyl ether.

  Patent Document 4 discloses a pesticide composition comprising a specific emulsion stabilizer, 2- (thiazol-4-yne) benzimidazole, a mixed solvent containing a glycol-based solvent and benzyl alcohol, and a surfactant. It is disclosed.

Apply the solution A as thinly and uniformly as possible on a polypropylene plate (50 mm x 100 mm x 2 mm), let it air dry at 20-30 ° C for 5 minutes, and then apply the solution B as thinly and evenly as possible at 20-30 ° C. Allow to air dry for a minute. This A solution coating → natural drying → B solution coating → natural drying was repeated 30 to 50 times to prepare a model bathroom stain.

An 8 mmφ paper disk was placed on the model bathroom stain, and 40 μl of the composition was dropped on the model bathroom and allowed to stand for 5 minutes, and then thoroughly rinsed with ion-exchanged water. Detergency was determined according to the following criteria. As a specific method, photograph the uncoated plate, the pre-cleaned plate after applying the stain, and the cleaned plate under the same shooting conditions such as brightness, and measure the gray scale of each plate from the obtained image. did. The cleaning rate of the plate after cleaning was calculated by setting the plate before cleaning to 0% for the plate before cleaning and 100% for the plate to which soil was not applied. The image processing software ImageJ 1.47v was used for the gray scale measurement.
1: Cleaning rate of less than 20% 2: Cleaning rate of 20% or more, less than 40% 3: Cleaning rate of 40% or more, less than 60% 4: Cleaning rate of 60% or more, less than 80% 5: Cleaning rate of 80% or more

<Bactericidal evaluation method>
Escherichia coli (strain NBRC3982) and Staphylococcus aureus (strain NBRC12732) were each cultured twice on a nutrient agar medium (prepared according to Nutrient Agar reagent manufactured by Difco) at 37 ° C. for 24 hours. Is suspended and dispersed in 1/2 Nutrient liquid medium (Difco's Nutrient Broth reagent prepared at 1/2 concentration of Nohsho), and bacteria are used using 1/2 Nutrient liquid medium. The concentration was adjusted to 2.5 to 13 × 10 ⁸ cfu / mL to obtain a test bacterial solution.

  In addition, a spore collection solution (prepared from Potato Dextrose Agar reagent manufactured by Becton Dickinson according to the written certificate) on a potato dextrose plate agar medium on which Cladosporium sp. 2 mL of Wako Pure Chemical Industries, Ltd., 0.05% TWEEN 80 solution prepared with water) is dropped, and gently rubbed with a large stick (manufactured by Nissui Pharmaceutical Co., Ltd.), and the recovered liquid is miracloth (CALBIOCHEM) The solution obtained by removing the mycelium by filtration using a product prepared by centrifugation was centrifuged at 10,000 rpm for 5 minutes to remove the supernatant. These operations were repeated 5 times, and a solution (10-fold concentrated) prepared with 1 mL of a spore recovery solution after the final centrifugation was used as a test spore solution.

10 μL of bacterial solution or spore solution adjusted to 10 ⁸ cfu / mL was mixed with 1 mL of the test solution, and contacted at 25 ° C. for 5 minutes, and then 100 μL was collected to obtain 900 μL of LP diluted solution (Nissui) The test solution was inactivated by suspending the product manufactured by Pharmaceutical Co., Ltd. in accordance with the Noh book. After further dilution with LP diluent, Escherichia coli and Staphylococcus aureus were added to lecithin polysorbate-80 soybean casein digest (Soybean-Casein Digest Agar with Lecithin & Polysorbate 80 '' DAIGO 80 WDA '' Reagents prepared as described in Noh) Apply to agar medium and incubate overnight at 37 ° C. Cladosporium is potato dextrose plate agar (prepared Potato Dextrose Agar reagent from Becton Dickinson) The number of surviving bacteria was calculated from the number of colonies obtained by culturing at 30 ° C. for 4 days.

  In addition, as a control operation, the same operation was performed using physiological saline instead of the test solution (10 μL of the bacterial solution was mixed with 1 mL of the test solution and contacted for 5 minutes and then mixed with the LP diluted solution). The logarithmic difference between the number of surviving bacteria after the control operation and the number of surviving bacteria after contact with the test solution was calculated and used as an index of the disinfection performance. In the table, “−” in the bactericidal column means that the bactericidal evaluation was not performed.

The components in the table are as follows.
Lauric acid amidopropyl betaine: In general formula (a1), R ¹ is a linear alkyl group having 11 carbon atoms, R ² and R ³ are each a methyl group, X is an alkylene group having 1 carbon atom, q is 1, r Is a compound of 3; sodium linear alkylbenzene sulfonate: linear sodium alkylbenzene sulfonate whose alkyl group is a mixed alkyl group of linear alkyl groups having 10 to 14 carbon atoms
