Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorant detergent for kitchenware such as tableware, cutting boards, kitchen knives, grilled fish, sponges and the like. [0002] Tableware,
On the hard surface of cutting boards etc., the odor of raw fish etc. tends to remain,
It is difficult to completely remove by washing. Unpleasant odors derived from foods such as raw fish are caused by amine compounds represented by ammonia, lower fatty acid compounds such as acetic acid and butyric acid, and sulfur compounds represented by mercaptan. Particularly, amine compounds are washed once. This is one of the unpleasant odors that cannot be easily removed. It is considered that the reason is that the odorous substance is attached to the hard surface in a state of being taken in an oily substance such as oil or wax. [0003] Detergents having a deodorizing performance include those in which a plant deodorant component is blended in JP-A-9-137194, and specific surfactants and chelating agents disclosed in JP-A-8-302393.
