Summary of the Invention

Problems to be Solved by the Invention

[0004] For example, in detergents for areas around water such as toilets and bathrooms, a bactericidal power against mold (Cladosporium) is required so that the generation of blackened stains can be prevented just by applying the detergent without scrubbing with a brush or the like. Also, for example, when applied to the hard surface of a toilet, in addition to the method of spraying foam into the toilet bowl and flushing it with water, it is desired to be able to use it by spraying foam on the toilet seat and floor and then wiping it off with toilet paper or the like. Therefore, it is required to have a large amount of foam when sprayed (good foaming property), be easy to wipe off, and have bactericidal power against mold, but it has been difficult for conventional technologies to sufficiently satisfy these requirements. An object of the present invention is to provide a liquid detergent for hard surfaces having good foaming property, wipe-off property, and bactericidal power.

The liquid detergent was discharged 5 strokes from this discharge container into a 200 mL tall beaker. The height of the foam was measured with a ruler, and the foaming property was evaluated based on the following evaluation criteria. A score of 5 points, 4 points, and 3 points was considered a pass. (Evaluation criteria) 5 points: The height of the foam is 1.2 cm / g or more. 4 points: The height of the foam is 0.8 cm / g or more and less than 1.2 cm / g. 3 points: The height of the foam is 0.6 cm / g or more and less than 0.8 cm / g. 2 points: The height of the foam is 0.4 cm / g or more and less than 0.6 cm / g. 1 point: Less than 0.6 cm / g.

[0072] <Evaluation of Bactericidal Activity against Molds (Cladosporium)> The bactericidal activity of each liquid detergent was evaluated as follows. (1) Preparation of Test Bacterial Solution Cladosporium cladosporioides HMC1064 cultured on a slant medium of potato dextrose agar (manufactured by Difco) at 25°C for 10 days was suspended in polyoxyethylene sorbitan monooleate (trade name "Tween 80", manufactured by Tokyo Chemical Industry Co., Ltd.) that had been autoclaved to prepare a spore solution of approximately 10 6 CFU / mL. (2) Preparation of Test Glass Plates 0.1 mL of the spore solution prepared in (1) was inoculated onto a slide glass and dried and fixed at room temperature for 2 hours. (3) Measurement of Bactericidal Activity 0.2 mL of the evaluation sample (the liquid detergent obtained in each example) was added to the slide glass in (2). After standing for 10 minutes, 10 mL of GPLP liquid medium (manufactured by Nippon Pharmaceutical Co., Ltd.) was added to wash out the bacteria. The solution was spread and inoculated onto potato dextrose agar (manufactured by Kanto Chemical Co., Inc.), and the number of colonies after culturing at 25°C for 5 days was counted to calculate the viable cell count. Also, 10 mL of GPLP liquid medium (manufactured by Nippon Pharmaceutical Co., Ltd.) was added to the slide glass in (2) to wash out the bacteria. The solution was spread and inoculated onto potato dextrose agar (manufactured by Kanto Chemical Co., Inc.), and the number of colonies after culturing at 25°C for 5 days was counted to calculate the viable cell count before treatment. The logarithmic value of the viable cell count obtained by subtracting the logarithmic value of the viable cell count of the evaluation sample from the logarithmic value of the viable cell count before treatment was defined as the bactericidal activity value, and the bactericidal activity was evaluated based on the following evaluation criteria. Points were assigned on a 5-point scale, and a score of 3 or more was considered passing. 《Evaluation Criteria》 5 points: The bactericidal activity value is 1.5 or more. 4 points: The antibacterial activity value is 1.3 or more and less than 1.5. 3 points: The antibacterial activity value is 1.0 or more and less than 1.3. 2 points: The antibacterial activity value is 0.8 or more and less than 1.0. 1 point: The antibacterial activity value is less than 0.8

[0073] <Wiping property> 100 μL of the liquid detergent of each example was placed on a slide glass and gently wiped once with a toilet paper folded into 8 layers. After drying, a professional panelist scored according to the following evaluation criteria for the remaining state of the wiping marks. A score of 3 or more was considered a pass. ≪Evaluation criteria≫ 5 points: No wiping marks remain at all. 4 points: Thin linear wiping marks remain, without stickiness. 3 points: Thin linear wiping marks remain, with a slight stickiness but not bothersome. 2 points: Wiping marks remain partially. 1 point: Wiping marks remain over the entire surface.

[0074] <Examples 1 to 43, Comparative Examples 1 to 6> Liquid detergents were produced with the formulations shown in the table (unit: mass%). The (F) component was put into 150 g of ion-exchanged water in a 300 ml beaker so that the total amount of the composition was 200 g on the scale, and stirred with a stirrer. Next, the (A1) component and the (A2) component were put in and stirred with a stirrer. Next, the (E) component and the (G) component were added and stirred, and then a pH adjuster was added so that the pH became about 7, and the remaining water was added and stirred to obtain a liquid detergent. Note that the formulation amounts in the table are values in terms of pure components. Also, components not listed in the table are not formulated. The content of the pH adjuster "appropriate amount" is the amount required to adjust the pH of the liquid composition of each example to a predetermined value. Also, the content of water "balance" means the remainder added so that the total formulation amount (mass%) of all the formulated components contained in the liquid composition becomes 100 mass%.
