Description of the Related Art Conventionally, as this kind of agent, a washing bleaching agent containing a surfactant and a bleaching agent as active ingredients has been used. It is said that there is a problem. In particular, on the back side of the washing tub, black molds, bacteria, and the like are propagated by using detergent residues, skin proteins, and the like as nutrients, and these adhere to the laundry and cause stains and unpleasant odors.

快臭の原因となっている。[0003] In recent years, so-called fully automatic washing machines have been widely used in home and commercial coin laundry. This washing machine is a fully automatic type in which each step of washing, rinsing, and dehydration is performed in one tub by simply putting laundry into a washing tub, and its convenience is accepted by modern lifestyles. It has spread rapidly. When a fatty acid-based detergent is used in such a washing machine, metal ions such as calcium and magnesium, which are hardness components in the water, react with fatty acid ions of the detergent to form a salt which is hardly soluble in water, so-called soap residue. As a result, it adheres to the washing tub of the washing machine, and deposits and accumulates particularly in deep places where it cannot be reached from the outside. The soap scum also contains organic debris and oils and fats removed from the laundry, so that it can be used as nutrients for black mold and bacteria to inhabit, and the washing tub becomes dirty black and produces an odor. However, the soap scum falls off and adheres to the laundry, causing stains and unpleasant odors.

However, this method requires a great deal of labor and labor, and it is difficult to remove soap scum and black mold. There has been a demand for the development of a washing agent for a washing tub that can easily wash the like.

As the above countermeasure, JP-A-1-213400 discloses that
A powder detergent comprising a chlorinated isocyanuric acid, an alkali builder and a nonionic surfactant is disclosed. However, in order to maintain the cleaning effect, the pH of the aqueous cleaning solution to which the detergent is added must be 11 or more. There is a problem that such an alkaline aqueous solution requires careful handling such as not to directly touch hands and body, and when the washing water after use is discarded, a neutralization treatment must be performed. .

After water was supplied to a washing tub with a high water level of 60 L to the high water level, 25 g of the above-mentioned washing tub cleaner was put into the washing tub, and after operating for 5 minutes, the washing tub was washed by leaving it for 2 hours. After that, the washing tub was rinsed by driving for 5 minutes. In order to confirm the cleaning effect of the product of the present invention, the amount of suspended solids in water in the washing tub at each stage after water was supplied to the washing tub, a washing tub cleaner was introduced to wash the washing tub, and after rinsing. (Hereinafter referred to as SS), turbidity and pH were measured. Table 1 shows the measurement results.

It is considered that the cleaner was peeled off and suspended in water, and it is recognized that the cleaner of the present invention has an excellent cleaning effect. Further, since the pH of the water in which the cleaner of the present invention is dissolved is neutral, there is no need for a neutralization treatment at the time of drainage.

The washing tub was washed and rinsed in the same manner as in Example 1 except that 35 g of the washing tub cleaner was charged. In order to confirm the effects of the product of the present invention, the number of general bacteria, the number of coliforms, and the pH were measured in the same manner as in Example 1.

As a comparative test, 300 g of a commercially available detergent (mainly composed of a nonionic surfactant and a percarbonate) was added instead of the laundry cleaner of the present invention, and the same treatment was performed. In order to compare and examine the effects of the product of the present invention and the commercial product, the number of general bacteria, the number of coliforms, and the pH were measured in the same manner as in Example 1. Table 3 shows the obtained measurement results.

と考えられる。According to the results of Example 3 in Table 3, it is recognized that the product of the present invention has an excellent effect on sterilization of a washing tub. However, according to the results of Comparative Example 1, it is considered that a detergent containing a percarbonate known as an oxygen bleach and a nonionic surfactant has poor sterilization performance and poor cleaning ability. That is, the number of general bacteria after rinsing is increased as compared to before the cleaning, because the contaminants such as soap scum sticking to the washing tub are not sufficiently washed away during the cleaning, and It is probable that some of the bacteria had not been killed and thus they had fallen into the rinse water.

用である。According to the present invention, a cleaner for a washing tub containing a chlorinated isocyanuric acid, an anionic surfactant and an inorganic builder is more effective than the conventional one containing a surfactant or a bleaching agent as an active ingredient. The ability to disinfect and clean black molds, bacteria and other contaminants adhered to the tank wall, especially the back side of the tank, is remarkable. Further, since the pH of the cleaning solution into which the cleaner of the present invention is added is neutral, there is no danger of irritating the skin when touching the body, and there is no need for a neutralization treatment when draining. It is extremely useful as a cleaner.
