  Dirt occurs in various places in daily life. Various cleaning agents have been developed to remove such dirt, and studies have been made to enhance the cleaning power. Through these efforts, many means for removing stubborn dirt have been proposed. In general, cleaning agents having compositions suitable for each of them are used 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. Such detergents are often adjusted to be alkaline with a pH of 10 or higher in order to exhibit high cleaning performance. Furthermore, it may be desirable that the cleaning agent used in the kitchen or the dining table can impart a bactericidal effect to the hard surface.

  Patent Document 1 discloses a nonionic surfactant and an amphoteric interface as a hard surface detergent composition that is difficult to adhere to dirt, that can easily be washed off, and that can provide good finish. Described is a hard surface cleaning composition containing at least one surfactant selected from activators and a polymer containing monomer units having a quaternary ammonium group or a tertiary amino group in a specific weight ratio.

The glass petri dish was capped at 25 ± 1 ° C. and left to stand. After confirming the drying of the bacterial solution, the composition was immediately inoculated. Cover the glass petri dish and let stand for 5 minutes. Five minutes after the composition inoculation, take care that the inoculated composition does not flow down. The fungicidal performance of the composition was inactivated, and the bacterial concentration in the LP diluted solution was counted by the pour culture method. A control operation was carried out using 0.05% Tween 80 aqueous solution instead of the composition, and a logarithmic difference in the number of bacteria with the control operation in the LP diluted solution was calculated and used as an index of sterilization performance.

  In addition, the one where this figure is large shows that sterilization performance is high, and it is preferable that it is 2.0 or more.

<Cleaning performance>
A model obtained by applying lauric acid to a polypropylene plate as a representative fatty acid contained in sebum soil was used as a model soil. Lauric acid was heated and dissolved, and 0.5% by mass of Sudan III was added and colored, and then a 2cm x 7cm x 1mm polypropylene plate was partially dipped and lifted up and soiled uniformly. The one that was cooled down was used as model dirt. A fixed amount (50 g) of the composition was placed in a 50 ml beaker, and the polypropylene plate with the model soil adhered was immersed so that all the soiled portions were immersed. After standing at room temperature for 30 minutes, the plate was gently pulled up and immersed in a solution prepared by another 50 ml beaker (softanol 70H (manufactured by Nippon Shokubai Co., Ltd.) 5 mass% added ethanol solution), and further subjected to ultrasonic waves for 15 minutes. The dirt remaining on the plate when applied was completely dissolved. 5% by mass of Softanol 70H (manufactured by Nippon Shokubai Co., Ltd.) was added to the composition in which the model soil was immersed for 30 minutes, and stirred well. The amount of lauric acid dissolved in the composition and the amount of lauric acid remaining on the plate were quantified with a spectrophotometer (Hitachi UV-3300), paying attention to the peak at 500 nm (in the vicinity of the absorption maximum of Sudan III). The washing rate was calculated.
Cleaning rate (%) = 100 × (dissolution amount in composition) / (dissolution amount in composition + residual amount in plate)

  In addition, the one where this numerical value is large shows that cleaning performance is high, 60% or more is preferable, and 70% or more is still more preferable.

  From Table 1, Examples 1 to 3 in which the mass ratio of the component (a) to the component (f) satisfies (f) / (a) = 0.01 to 0.3 have soft foams and good wiping properties. I understand.

  In Comparative Examples 1 and 2 in which the value of (f) / (a) is less than 0.01, the effect of improving the foam quality and the effect of improving the wiping property are insufficient, and the value of (f) / (a) is 0.3. In Comparative Example 3 exceeding 1, not only is the foam too soft, but it is also found that the wiping property is not improved as expected because the component (f) is too much.

  In Table 2, Comparative Example 4 has a composition substantially corresponding to that obtained by removing “Polymer 1” from “Invention Product 6” in Table 1 of Patent Document 1 (Japanese Patent Laid-Open No. 2002-146395). Since the value of (f) / (a) exceeds 0.3, wiping property and cleaning performance are low. Further, in Table 2, Comparative Example 5 has a composition corresponding to “Product 1 of the present invention” in Table 1 of Patent Document 2 (Japanese Patent Laid-Open No. 2008-44993), but the component (f) is added to dipotassium alkenyl succinate. Even if it adds, it turns out that the foam quality improvement effect and wiping property improvement effect like this invention are not acquired. Moreover, since the ratio (d) / (e) of the solvent is not appropriate, the cleaning performance is slightly inferior to that of the example. In Comparative Example 6 in which the component (b) is added to the comparative example 5, the foam quality improving effect and the wiping property improving effect cannot be obtained, and the anionic component and the component (b) are electrostatically interacted with each other. It turns out that sterilization performance is not obtained.
