Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a sponge, a cutting board,
The present invention relates to a detergent composition which is suitable for sterilizing and cleaning kitchen utensils such as cloths, tableware such as plates, and foods such as vegetables and fruits, and which has extremely low handiness.

[0002]

2. Description of the Related Art Generally, kitchen utensils such as sponges, cutting boards and cloths and tableware such as plates are contaminated with harmful microorganisms derived from raw food materials. Therefore, at home, disinfection with chlorine bleach, hot water disinfection, dry disinfection, sunlight disinfection, etc. are performed. In addition, foods such as vegetables and fruits are easily contaminated with harmful microorganisms, and thus the outflow removal by washing with a neutral kitchen detergent is generally performed at home.

However, it is complicated to sterilize tableware by the above-mentioned means, and in foods, since the quality such as flavor is deteriorated, it is preferable to use a sterilization means other than the outflow removal by the neutral detergent for kitchen. Can not. In addition, removal of spills with a neutral detergent is a physical method, and thus removal of bacteria may be incomplete.

Therefore, a cleaning agent having both a cleaning effect and an excellent bactericidal effect is desired. Japanese Patent Laid-Open No. 7-188696 discloses a neutral liquid detergent composition which is composed of only edible components as such a detergent and has a bactericidal effect. However, even with such a cleaning agent, the antibacterial activity cannot be said to be sufficient, and since the cleaning power is also poor,
A cleaning agent having stronger bactericidal power and detergency is desired. In addition, recently, since there is an increasing demand for a mildness of the detergent to the body, a composition which has not only high foaming power, detergency and bactericidal power but also extremely gentle and less rough on the skin is obtained. Especially requested.
