Thereafter, the test piece was taken out, rinsed and dried with ion-exchanged water, the appearance of the test piece surface was visually observed, and corrosivity was determined according to the following criteria.
Evaluation criteria:
○: No corrosion
Δ: Corrosion is slightly observed, but there is no problem in use. ×: Corrosion is assumed, and ○ and Δ are determined to be practical.

* 8: Iron corrosion prevention test The test piece [cast iron (FC-200), length 50 mm × width 30 mm × thickness 3 mm], which has been previously washed with a neutral detergent, treated with acetone and dried is used. The test piece was immersed in 400 ml of a cleaning solution in which each foaming detergent composition was diluted to 5% by mass with hard water of 75 mg / L [German hardness 4.2 ° DH] in terms of calcium carbonate. Let stand for 1 hour. Thereafter, the test piece was taken out, rinsed and dried with ion-exchanged water, the appearance of the test piece surface was visually observed, and corrosivity was determined according to the following criteria.
Evaluation criteria:
○: No corrosion
Δ: Corrosion is slightly observed, but there is no problem in use. ×: Corrosion is assumed, and ○ and Δ are determined to be practical.

* 9: Bactericidal test method:
The final concentration of 1.5 to 5.0 × was added to 10 mL of a cleaning solution prepared by diluting each foaming detergent composition in terms of calcium carbonate to 5% by mass with hard water of 75 mg / L [German hardness 4.2 ° DH]. A test solution was prepared by adding 0.1 mL of a bacterial solution so as to be 10 ⁵ (CFU / mL) and maintaining the solution at 25 ° C. for 5 minutes. 1 mL of this test solution was mixed and solidified on an SCDLP agar medium and cultured at 37 ° C. for 2 days. After culturing, the number of viable bacteria was measured, and sterilization was evaluated according to the following criteria from the difference from the initial number of bacteria.
Test strain: Pseudomonas aeruginosa NBRC13736 from the Fermentation Research Institute
Evaluation criteria:
○: Log reduction of the test bacterium was 5 or more ×: Log reduction of the test bacterium was less than 5, and ○ was judged as practical.
