  In recent years, interest in hygiene has increased, and it has been practiced to give a sterilizing effect to toiletry products such as detergents and softeners. In particular, since tableware detergents and cutting boards that are in direct contact with food are objects to be cleaned, it is strongly desired to give a sterilizing effect to the detergent. On the other hand, such detergents contain a high concentration of surfactant, but in such a system, there is a problem that the expected sterilization effect cannot be obtained even if a normal antibacterial agent is used. is there.

  Some anionic surfactants and amphoteric surfactants are known to have antibacterial effects. However, commercially available detergents are designed to improve the detergency with anionic surfactants and amphoteric surfactants. It is common to use agents together. In such a system, an anionic surfactant and an amphoteric surfactant form a complex, so that a sufficient disinfection effect cannot be obtained. Therefore, there is a demand for a technique that effectively imparts a sterilizing effect to a composition comprising a high concentration surfactant containing an anionic surfactant and an amphoteric surfactant.

  As disclosed in Patent Documents 1 and 2, it is already known that glyceryl ether has a sterilizing effect. However, in a composition containing a high concentration of surfactant, glyceryl ether alone shows little disinfecting effect.

  Patent Documents 3 and 4 disclose a detergent composition having a sterilizing effect with a high surfactant concentration containing glyceryl ether, and citric acid is described as an optional component in the detailed description of the publication. ing. However, these technologies are technologies that impart sterilization effects with other antibacterial agents, and it is completely described that a high sterilization effect can be imparted by containing specific amounts of glyceryl ether and citric acid of a specific structure. It has not been.

Although there are Patent Literatures 5 to 8 regarding the bactericidal detergent composition containing citric acid, synergistic sterilization effect can be achieved by using glyceryl ether having a specific structure and citric acid in combination even if these techniques are taken into consideration. There is no disclosure at all about the point that a high sterilization effect can be exhibited in a composition containing a high concentration of surfactant.

  Patent Document 9 discloses that a mixture containing 1- (2-ethylhexyl) glycerin ether is used to sterilize the surface of an article at 25 ° C. or higher, and citric acid is used as another drug constituting the mixture. And a surfactant is described as one of the auxiliaries. However, there is no disclosure of an example in which 1- (2-ethylhexyl) glycerin ether, citric acid, and a surfactant are combined, and there is no disclosure that the bactericidal power is improved by combining these.

  Therefore, in the present invention, a disinfecting detergent having a high disinfecting effect, and a high disinfecting effect, especially in a composition containing a high concentration surfactant such as a dishwashing detergent, and a disinfecting treatment method It is an issue to provide.

It was crowded. After sealing the bottle, it was allowed to acclimate for 1 hour at 25 ° C., and 0.5 ml sponge was inoculated with the sterilizing detergent shown in Table 1. At this time, as a control, the same treatment was performed with 0.05% polysorbate 80 which does not affect the growth of the fungus. Next, it was uniformly squeezed with a new sterilized glass rod, sealed again, and left at 25 ° C. for 18 hours.

  After standing, 20 ml of neutralizing agent was added to the screw mouth bottle, and the sponge was uniformly squeezed with a sterilized glass rod. A dilution series was prepared using this solution, and the number of colonies was measured by a flat plate coating method.

  The sterilization effect was judged using a numerical value (sterilization activity value) obtained by subtracting the common logarithm of the number of bacteria after the test from the common logarithm of the control sample. If the numerical value is high from the definition, the sterilization effect is high.

  From the comparison between Example 1 and Comparative Examples 1, 4, and 5, it was confirmed that the sterilization effect was remarkably improved by using the components (a) and (b) together. And it was confirmed from comparison with Example 1 and Comparative Examples 2 and 3 that the disinfection effect improves remarkably by adjusting content of (a) component and (b) component.

  The disinfectant cleaning agent of Example 1 can be applied to various cleaning agent uses, and can exhibit a high disinfecting effect and a cleaning effect. When the treatment target is washed with this sterilization detergent, the sterilization effect is enhanced by both the sterilization effect by the components (a), (b), and (c) and the bacteria removal effect (cleaning effect). .

Examples 2-8, Comparative Examples 6, 7
A cleaning composition was prepared using the components shown in Table 2. At that time, pH was adjusted using 48% sodium hydroxide. After the adjustment, the sterilizing effect of these compositions was evaluated in the same manner as in Example 1. The results are also shown in Table 2.

  As is clear from the comparison of the sterilization activity values of Examples 2 to 8 and Comparative Examples 6 and 7, the sterilization effect is synergistically improved by using the components (a), (b), and (c) in combination. It was.

Formulation Example Using the components shown in Table 3, a disinfecting detergent was prepared in the same manner as in the example.
