[0145] [Cleaning power]

[0146] The cleaning power against denatured oil stains was evaluated.

[0147] 0.02 g of rapeseed oil was uniformly applied to one side of a stainless steel sheet (70 mm x 25 mm) (1 / 2 ≤ (area of application / area of one side of the stainless steel sheet) ≤ 3 / 4). This was left in a 170°C holding furnace for 0.5 h, then cooled to room temperature and weighed, and this weight was taken as Wl.

[0148] A number of pieces of nonwoven fabric (synthetic fiber base, 40 ± 4 g / m 2 , Watahiki Textile Co., Ltd.) measuring 100 mm x 70 mm were cut out, and 1 ml of the cleaner composition of each of the examples and comparative examples in Tables 1 to 4 was added dropwise to each of these nonwoven fabrics, to produce a cleaning sheet for hard surfaces ([mass of the cleaner composition / mass of the base in the non-impregnated state (dry state)] x 100 = 320 mass %). This was then wrapped around an eraser (15 mm x 40 mm x 10 mm) that had been wrapped with aluminum foil.

[0149] The surface of the stainless steel sheet was wiped once with the 15 mm x 40 mm face of the eraser wrapped around the cleaning sheet impregnated with the cleaner composition of Example 1. After waiting for 10 minutes, the stainless steel sheet was weighed again, and this weight was taken as W2.

[0150] The stain on the stainless steel sheet was completely removed, dried, and weighed, and this weight was taken as W0.

[0151] Cleaning power = [(Wl - W2) / (Wl - W0)] * 100 (%)

[0152] W0, Wl, and W2 were calculated to five decimal places at the time of measurement. The results of the calculation were recorded in the table.

[0153] Then, the above operation was repeated, and the remaining examples / comparative examples in Tables 1 to 4 were completed using the same wiping method as in Example 1.

[0157] A number of pieces of nonwoven fabric (synthetic fiber base, 40 ± 4 g / m 2 , Watahiki Textile Co., Ltd.) measuring 20 cm x 14 cm were cut out, and 4 ml of the cleaner composition of each of the examples and comparative examples in Tables 1 to 4 was added dropwise to each of these nonwoven fabrics, to produce a cleaning sheet for hard surfaces (mass of the cleaner composition / mass of the base in the non-impregnated state (dry state) = 320%).

[0158] Use this cleaning sheet to wipe either side of a glass plate (from one edge to the other) 10 times, back and forth, until the entire glass is soaked. Then, take a photo of the wiped glass plate and process the image (using ImageJ) to measure the remaining white residue area on the glass plate. The remaining white residue rate is calculated based on the treated area of ​​the glass plate and evaluated according to the following criteria.
