JP6097639B2 - Cleaning composition and method of using the same - Google Patents

Description

  The present invention relates to a cleaning composition that can be used mainly in food production sites and kitchens, has a high cleaning effect and sterilization effect, and has no unpleasant odor, and a method of using the same.

  Detergents used in food production sites and kitchens are required to have a high cleaning effect, but also have a sterilizing effect as a countermeasure against food poisoning and other pathogenic bacteria. Further, such a cleaning agent is often used on a vertical surface, and it is necessary to impart a certain viscosity to prevent dripping from the vertical surface.

  In order to satisfy these requirements, conventionally, an anionic surfactant as a cleaning component, an amine oxide for imparting a certain viscosity, and a chlorine compound such as sodium hypochlorite for further sterilizing effect Agents have been used (see, for example, Patent Documents 1 to 3). Amine oxide can form a thixotropic thickener by forming a complex with an anionic surfactant. However, sodium hypochlorite added to give sterilization has an irritating odor, which not only makes the user feel uncomfortable, but also improves the health of the user by using it in an enclosed space. The adverse effects of have been pointed out.

  Therefore, in order to obtain a sterilizing effect without using a chlorine compound such as sodium hypochlorite, the use of a cationic surfactant has been studied. Most cationic surfactants have a certain sterilizing effect, but adding a normal cationic surfactant to a system containing an anionic surfactant and an amine oxide results in an anionic surfactant and a cationic surfactant. As a result, a complex is formed, the cleaning effect is lowered, and the viscosity of the system is also lowered. On the other hand, a sufficient cleaning effect cannot be obtained with a system composed of a cationic surfactant and an amine oxide without using an anionic surfactant. In addition, disinfectants other than chlorine compounds such as sodium hypochlorite and cationic surfactants may be used when the disinfection effect is weak, the human body is highly irritating, or as a raw material for cleaning agents. It may be expensive and impractical, and is unsuitable for use as a raw material for detergents in places where foods are handled.
