A drug in which a nonionic surfactant is mixed with an amphoteric surfactant is known. In addition, a strong alkaline detergent prepared by mixing a caustic soda with a chlorine-based agent is also well known as a detergent and disinfectant. However, since a cleaning agent containing a chlorine-based chemical has drawbacks such as having a pungent odor and corroding the apparatus, it is not always preferred as a cleaning agent and a disinfecting agent for food factories.

It is widely used because of its advantages such as excellent cleaning effect. However, this cleaning agent also has a drawback that it gradually attacks the surface of stainless steel, which is a material of food manufacturing or processing equipment, and finally turns the surface into blackish brown. Such a phenomenon is
It is presumed that this is due to the formation of an oxide film on the surface of stainless steel, but this film may peel off during food production or processing, which causes a serious problem of contaminating food. .
