The HLB of a mixed surfactant consisting of two or more nonionic surfactants is the arithmetic average of the HLB values ​​of each nonionic surfactant based on their blending ratio, and can be calculated by the following formula (3): Mixed HLB=Σ(HLBx×Wx) / ΣWx (3) Here, HLBx is the HLB value of nonionic surfactant X, and Wx is the mass (g) of nonionic surfactant X having the HLBx value.

[0016] POE(n) lauryl ether (POE is an abbreviation for polyoxyethylene) can be used as component (A). Specifically, one or more of POE(16) lauryl ether (HLB 16.2) (a polyoxyethylene lauryl ether in which n is 16 and has an HLB of 16.2; the same notation applies hereinafter), POE(21) ​​lauryl ether (HLB 17.0), and POE(41) lauryl ether (HLB 18.3) can be used as component (A). Among these, POE(21) ​​lauryl ether (HLB 16.2) is preferred as component (A) from the viewpoints of detergency, foam quality, and foam-breaking properties.

[0037] From the viewpoint of adjusting foam quality, a porous membrane filter such as a mesh-like body is preferably provided in the discharge flow path of the foamer container for the detergent composition (for example, provided in the lid body). The porous membrane filter may be arranged in the discharge flow path so that it extends in a direction intersecting the flow direction of the detergent composition, so that the detergent composition filled in the container body passes through the porous membrane filter as it flows through the discharge flow path. From the viewpoint of obtaining finer and better foam quality, such a porous membrane filter is preferably a filter with 90 to 400 mesh (here, "mesh" refers to the number of openings per inch), more preferably a filter with 200 to 400 mesh, and even more preferably a filter with 200 to 305 mesh. Preferably, 1 to 3 such porous filters are arranged in the discharge flow path, and more preferably 2 filters are arranged.

[0040] Examples of foamer containers that can be used include known pump foamer containers, squeeze foamer containers, electric whisks, and pressure-accumulating pump foamer containers that have foam discharging means. More specifically, examples include the Pump Former E3 Type and F2 Type (both manufactured by Yamato Can Co., Ltd.) described in Food and Containers (Vol. 35, No. 10, pp. 588-593 (1994); Vol. 35, No. 11, pp. 624-627 (1994); Vol. 36, No. 3, pp. 154-158 (1995)), a squeeze foamer (manufactured by Yamato Can Co., Ltd.), an electric whisk (manufactured by Matsushita Electric Works), and an air spray foamer (manufactured by Air Spray International).

[0042] The detergent composition may be used to wash the body without applying friction to the skin or hair with a solid (for example, fingers, a sponge, a brush, or the like). The cleaning method of the present embodiment may also include using the detergent composition to wash the body without applying friction to the skin or hair with the solid. In such a detergent composition or cleaning method, when the detergent composition is filled in the former container, the foamed detergent composition discharged from the former container may be applied to the skin or hair, thereby removing dirt. When the detergent composition is used in the shower, the detergent composition may be mixed with water supplied from a shower hose in the unit structure, and a cleaning liquid containing the detergent composition may be sprayed from a shower head, and the sprayed cleaning liquid may be applied to the skin or hair, thereby removing dirt.

[0043] The viscosity of the cleaning composition of this embodiment at 25°C is preferably 1 to 10,000 mPa·s, more preferably 1 to 1,000 mPa·s, and even more preferably 1 to 100 mPa·s, from the viewpoint of dischargeability from a container or shower. A viscosity within this range ensures high fluidity of the cleaning composition, resulting in good dischargeability. Particularly when the container is a non-gas foamer container, the viscosity of the cleaning composition of the present invention at 25°C is preferably 1 to 30 mPa·s, more preferably 1 to 20 mPa·s, and particularly preferably 1 to 12 mPa·s, in order to facilitate operability with human fingers and to ensure discharge in a good foam state.

[0048] <Examples 1-1 to 4-7, Comparative Examples 1-1 to 2-3> Detergent compositions were produced with the formulations shown in Tables 1 to 4. The resulting detergent compositions were discharged from a foamer container to produce foam, and the detergency, foam breaking ability, and foam quality of the foam were evaluated. The results are also shown in Tables 1 to 4.

[0049] (Manufacturing method) The components were mixed and dissolved in ion-exchanged water to produce a cleaning composition. The resulting cleaning composition was filled into a former container. The former container used was one described in Japanese Patent No. 5608433 (a foam-discharging container 10 comprising a container body 12 made of polypropylene and filled with the cleaning composition, a lid 14 attached to the upper opening of the container body 12, and two mesh-like bodies (corresponding to a first mesh 28 and a second mesh 30, respectively) serving as porous membrane filters arranged inside the lid 14 (discharge flow path) so as to expand in a direction intersecting the flow path direction of the cleaning composition).

[0050] (Evaluation method) "Evaluation of foam cleaning power" Model sebum (dirt) stained with 2% NIPex160 IQ POWDER (ORION Engineered Carbons GmbH) was applied to three 3cm square areas on the inside of one forearm, each 20μL in size. One pump of foam was applied to one stain, and the same process was repeated for the other two stains. The inner forearms were then placed facing each other and left to stand for two minutes. Tap water (approximately 40°C) was then used to rinse the stains, running down the arms over them for 10 seconds, avoiding direct contact with the stains. After rinsing, the stain removal from each of the three stains was visually evaluated (scored) on a five-point scale, and the average of the three scores was used to determine the cleansing power of the foam (see Figure 1). 1: Doesn't come off at all 2: Slight drop 3: Falls by about half 4: Almost falls off 5: Completely falls off The cleaning power of the foam (average value of three locations) was evaluated according to the following criteria. ◎: 4.5 or higher. Extremely high cleaning power 〇: 4.0 or more but less than 4.5. High cleaning power △: 3.0 or more but less than 4.0. Good cleaning power ×: Less than 3.0. No cleaning power

[0051] "Evaluation of foam breaking ability" 100 mL of an aqueous solution of the detergent composition diluted 500 times with tap water (approximately 24°C) was poured entirely into a 500 mL separatory funnel. The funnel was covered and vigorously shaken up and down, and then the stopcock was opened and the water was drained for 20 seconds. The stopcock was closed, and 100 mL of tap water was poured into the funnel. The funnel was covered and vigorously shaken up and down, and then the stopcock was opened and the water was drained for 20 seconds. The stopcock was closed, and the distance from the top of the foam remaining in the separatory funnel to the stopcock was measured, and the foam breaking ability was evaluated according to the following criteria. ◎: The distance from the top of the foam remaining in the separatory funnel to the stopcock is less than 5 cm 〇: The distance from the top of the foam remaining in the separatory funnel to the stopcock is 5 cm or more but less than 5.5 cm △: The distance from the top of the foam remaining in the separatory funnel to the cock is 5.5 cm or more but less than 6 cm ×: The distance from the top of the foam remaining in the separatory funnel to the cock is 6 cm or more.

[0052] "Evaluation of foam quality" 1 mL of the detergent composition was dropped onto the palm of a hand lightly wetted with tap water (approximately 24°C), and the palm was rubbed back and forth between hands 50 times. The state of the resulting foam was observed by touch and visually, and the foam quality was evaluated according to the following criteria (see Figure 2). ◎: The bubbles are small, the whole bubble looks white, and it is bulky. 〇: The bubbles are small and appear white △: There are many slightly larger bubbles, and the overall whiteness of the bubbles is low. ×: There are many large bubbles and your palm is visible through the foam.
