Description

  The present invention relates to a detergent for tableware.

  Storage containers for storing food materials are widely used in general households, and plastic containers in particular have a high usage rate in general households. However, the plastic container has a problem that not only the surface is easily soiled with greasy dirt, but also the odor of the foodstuff that has been stained is difficult to remove. In view of such circumstances, many studies have been made on the removal of food odor (see, for example, Patent Documents 1 to 5).

JP 2000-212593 A JP 2000-212594 A JP 2000-212597 A JP 2003-82400 A JP 2006-2091 A

  However, when a conventional cleaning agent is used, immediately after cleaning, even if the deodorizing power and the masking power of the fragrance can be removed to the extent that the food odor of the plastic container does not matter, the plastic container is stored afterwards. Then, when it is reused, an unpleasant odor is felt and it may be necessary to clean it again.

  The present invention has been made in view of the above circumstances, and can be used not only for removing stains and food odors when washing tableware such as plastic containers, but also for suppressing tabletop odors after storing plastic containers. The issue is to provide cleaning agents.

  As a result of intensive studies, the present inventors have identified 2-ethylhexyl glycol, 2-ethylhexyl diglycol, and the like for component (a) such as sodium polyoxyethylene alkyl ether sulfate and component (b) such as amine oxide. It was conceived that the above problem can be solved by combining the glycol solvent (c) of HLB and a specific alkanol (d) of HLB such as 2-ethylhexanol, 1-octanol and 2-octanol.

The present invention has the following configuration.
[1] One or more selected from the group consisting of (a) an anionic surfactant, (b) an amphoteric surfactant and a semipolar surfactant, and (c) HLB is 8.5 to 10.5. One or more glycol solvents and (d) one or more alkanols having an HLB of 6.0 to 7.0, [(a) + (b)] / [(c) + (D)] is a mass ratio represented by 2.0 to 15.0, and a mass ratio represented by (c) / (d) is 0.2 to 5.0.

The cleaning agents in the examples described in Tables 1 to 3 are compared to the cleaning agents in the comparative examples described in Table 4, the cleaning performance evaluation of food stains, the odor evaluation of the container immediately after cleaning, and the odor after storage in the container. Each evaluation result of the evaluation was excellent with good balance. There was also no problem with the solvent odor residue.
For example, from the results of Examples 1 to 5 and the results of Examples 6 to 9, the mass ratio (c) / (d) and the mass ratio [(a) + (b) / (c) + (d)] Has an effect on odor suppression after container storage, and it can be understood that when these mass ratios are in a more appropriate range, the odor suppression effect after container storage is more excellent.
Further, from the comparison between Examples 3 and 33 and the comparison between Example 3 and Examples 34 and 35, 2-ethylhexyl glycol of (c-1) was used as the (c) component, and (d) When 2-ethylhexanol of d-1) was used, it was understood that the odor suppression after container storage was very excellent.
Furthermore, from the comparison of Examples 3 and 10, it was understood that the odor suppressing effect after storage of the container can be further enhanced by including the component (e).
Moreover, from the result of the comparative example 13, it was clear that only the component (a), the component (b), and the component (e) do not provide the effect of suppressing odor after storage.
