JP5033380B2 - Disinfectant composition and disinfectant cleaning composition for tableware, cooking utensils, food processing plant or kitchen, and sterilization method or disinfecting cleaning method for tableware, cooking utensils, food processing plant or kitchen facilities using the same - Google Patents

Description

The present invention relates to a disinfectant composition and a disinfectant cleaning composition for tableware, cooking utensils, food processing plants or kitchens , and more particularly, in the case of contamination with proteins or the like during use. The present invention also relates to a bactericidal composition and a bactericidal cleaning composition in which the bactericidal power of a cationic bactericide is unlikely to decrease even under hard water containing a large amount of minerals such as calcium and magnesium. In addition, the present invention relates to a sterilization method or sterilization cleaning method for dishes, cooking utensils, food processing plants or kitchen facilities using these.

Bactericides mainly composed of cationic bactericides are used in a wide range of fields because of their broad antibacterial spectrum, immediate effect, and efficacy at low concentrations.
Moreover, most of the bactericides mainly composed of a cationic bactericidal agent are usually diluted with water. However, the water used for dilution at the time of use is tap water or well water at the place of use, and these generally contain minerals such as sodium, calcium and magnesium as hardness components. It is widely known that a significant decrease in sterilization performance occurs.

On the other hand, as a liquid detergent composition used for hand washing washing of tableware and cooking utensils, a detergent composition mainly composed of an anionic surfactant is used. However, most of the cleaning compositions of this type have no sterilizing power and some have a sterilizing power , but the sterilizing effect is very slight.

Therefore, in places where stronger sterilizing power is required, a sterilizing detergent that combines a cationic surfactant as a sterilizing component and a nonionic surfactant or amphoteric surfactant as a sterilizing component so that sterilization and cleaning can be performed simultaneously. A composition is used.
However, since this type of sterilizing detergent composition is diluted with water and used, the sterilization performance is significantly reduced by the above hardness components, and also when sterilization such as protein is mixed, remarkable sterilization performance It is widely known that this occurs.

  In order to prevent the deterioration of the sterilizing performance for these dishes and cooking utensils, etc., a method using a metal chelating agent such as ethylenediaminetetraacetate or nitrilotriacetate is employed (for example, see Non-Patent Documents 1 to 3). These sequestering agents are concerned with difficulty in biodegradability and carcinogenic problems. In addition, since heavy metal ions in hard water are captured by chelating action, the sterilization performance is not easily lowered, but there is a disadvantage that the cleaning performance is lowered because it is not effective for dirt such as protein. Moreover, when the said metal chelating agent is mix | blended abundantly in a composition, it also has the fault that it will lack a storage stability.

In addition, a sterilization method in which a sterilizing power can be maintained even when a sterilizing performance is deteriorated by adding an excessive amount of a cationic sterilizing agent to the composition has been used. However, if an excessive amount of cationic bactericidal agent is added, the bactericidal performance is not easily lowered even when dirt such as protein is mixed in hard water, but this requires a large amount of cationic bactericidal agent. It has the disadvantage of not being correct.
