<Clean force evaluation method>

Evaluate the cleansing power of the sample bathroom dirt made up of soap residue and sebum. The method for producing sample dirt is shown below. The solid soap (KAO White) 90% by mass and the sample sebum soil 10% by mass were mixed at 50 to 60 ° C and kept warm, and the resulting solution was designated as the A solution. Further, the composition of the sample sebum soil was 40% by mass of linoleic acid, 20% by mass of oleic acid, 20% by mass of palmitic acid, 10% by mass of cholesterol, and 10% by mass of liquid paraffin. The calcium chloride solution having a hardness of 10 ° dH in Germany was incubated at 20 to 30 ° C, and the resulting solution was set as a B solution. The A solution was uniformly coated as thin as possible on a polypropylene plate (50 mm × 100 mm × 2 mm), naturally dried at 20 to 30 ° C for 5 minutes, and then the B solution was uniformly applied as thin as possible at 20 to 30 ° C. Dry naturally for 5 minutes. The coating A solution → natural drying → coating B solution → natural drying operation was repeated 30 to 50 times to prepare a sample bathroom dirt.

之紙碟，向其中滴加組合物40μl並放置5分鐘後，利用離子交換水充分地沖洗。利用以下基準判定清潔力。作為具體方法，對未塗佈污垢之板、塗佈污垢後且清潔前之板、清潔後之板於明亮度等攝影條件相同之狀態下進行攝影，由所獲得之圖像測定各板之灰度。將清潔污垢前之板設為清潔率0%，將未塗佈污垢之板設為100%，算出清潔後之板之清潔率。灰度之測定中使用圖像處理軟體ImageJ 1.47v。 Set 8mm for sample bathroom dirt

On a paper plate, 40 μl of the composition was added dropwise thereto and left for 5 minutes, and then sufficiently rinsed with ion-exchanged water. The cleaning power was determined using the following criteria. As a specific method, the uncoated dirt board, the board after the stain is applied, the board before cleaning, and the board after cleaning are photographed in the same state of photography such as brightness, and the gray of each board is measured from the obtained image. degree. The board before cleaning the dirt was set to a cleaning rate of 0%, and the board to which the dirt was not applied was set to 100%, and the cleaning rate of the board after cleaning was calculated. The image processing software ImageJ 1.47v was used for the measurement of gray scale.

1: cleaning rate is less than 20%

2: The cleaning rate is over 20% and less than 40%

3: The cleaning rate is above 40% and less than 60%

4: The cleaning rate is above 60% and less than 80%

5: Cleaning rate is over 80%

<Bactericidal evaluation method>

Scraping Escherichia coli (strain NBRC3972) and Staphylococcus aureus (strain NBRC12732) on a nutrient agar medium (manufactured by Difco's Nutrient Agar reagent according to the efficacy manual) was repeated twice at 37 ° C / 24 hours. Suspended and dispersed in 1/2 nutrient liquid medium (using the Nutritional Broth reagent manufactured by Difco Co., Ltd. at a concentration of 1/2 of the efficacy specification), using a 1/2 nutrient liquid medium to adjust the bacterial concentration to 2.5~ The test bacterial solution was prepared at 13 × 10 ⁸ cfu/mL.

Further, on a potato dextrose agar medium (using a Potent Dextrose Agar reagent manufactured by Becton Dickinson Co., Ltd. according to the efficacy specification), which is grown with Cladosporium sp. PA-4, spore recovery liquid is used (utilizing a large sputum) 2 mL of a 0.05% TWEEN80 solution manufactured by Wako Pure Chemical Industries Co., Ltd., which is manufactured by the Pharmaceutical Factory Co., Ltd., to be sterilized by a bacteria spreader (made by Rishui Pharmaceutical Co., Ltd.) The method is lightly rubbed, and the recovered liquid is filtered using Miracloth (manufactured by CALBIOCHEM) to remove the bacteria. For the silk, the obtained liquid was centrifuged at 10,000 rpm for 5 minutes to remove the supernatant. This operation was repeated 5 times, and finally centrifuged, and then adjusted with 1 mL of the spore recovery liquid, and the obtained liquid (10-fold concentration) was set as the test spore liquid.

1 mL of the test solution was mixed and adjusted to 10 ⁸ cfu/mL of bacterial liquid or spore solution 10 μL, and after contact for 5 minutes at 25 ° C, 100 μL of the solution was taken and suspended in 900 μL of LP (Lecithin Polysorbate, lecithin polysorbate) Diluting solution (made by the manufacturer of Nishui Pharmaceutical Co., Ltd. according to the efficacy specification), whereby the test solution is not activated. After further diluting with a LP diluent, Escherichia coli and Staphylococcus aureus are coated to lecithin-polysorbate-80 plus soybean-casein-digest (manufactured by Wako Pure Chemical Industries Co., Ltd.) The Soybean-Casein Digest Agar with Lecithin & Polysorbate 80 "DAIGO" reagent was prepared according to the efficacy instructions), cultured at 37 ° C overnight, and the Mycobacterium spp. was applied to potato dextrose agar medium (manufactured by Becton Dickinson) The Potato Dextrose Agar reagent was prepared according to the efficacy specification, and cultured at 30 ° C for 4 days, and the number of the residual bacteria was calculated from the number of colonies obtained.

In addition, the same operation was carried out using physiological saline instead of the test solution (10 μL of the mixed solution of 1 mL of the test solution, and after mixing for 5 minutes, mixed with the LP diluent) as a control operation, and the number of residual bacteria and the test solution after the control operation were calculated. The logarithmic difference of the number of bacteria in the number of residual bacteria after contact is used as an indicator of the sterilization performance. Further, in the table, "-" in the bactericidal column means that the bactericidal evaluation is not performed.
