JP-A-8-311487

Compared to general kitchen equipment, the temperature of waste water when washing stipon tends to be higher. For this reason, HT pipes (heat-resistant rigid polyvinyl chloride pipes) are often used as drainage pipes for styrene.
However, a problem has arisen that when a stipon is washed for a long period of time using a conventional cleaning agent, a crack occurs in the HT pipe, leading to a water leakage accident.

It is thought that the main cause of cracking in the HT tube is a glycol ether solvent contained in the cleaning agent. It is presumed that the polyvinyl ether pipe such as the HT pipe deteriorates due to the glycol ether solvent.

Therefore, it is considered that the deterioration of the drain pipe of styrene can be suppressed by reducing the content of the glycol ether solvent in the cleaning agent.
However, the glycol ether solvent is an important component for cleaning strong oil stains adhering to stycon. Therefore, if the content of the glycol ether solvent is reduced, there arises a problem that the stycon cannot be sufficiently washed.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a stycon cleaning composition having sufficient detergency while suppressing deterioration of the drain pipe.
Another object of the present invention is to provide a method for cleaning stycon using the cleaning composition.

Patent Document 1 does not recognize the problem that the drain pipe of stycon deteriorates during cleaning. Therefore, the solution for cleaning the stycon is naturally not disclosed.

If the content of the fatty acid or salt thereof is less than 0.1% by weight of the surfactant, the detergent composition may not have sufficient foaming power and may have poor cleaning power. On the other hand, even if the content of the fatty acid or a salt thereof exceeds 40% by weight of the surfactant, there is no significant effect on the improvement of foaming power. Further, when the content of the fatty acid or the salt thereof exceeds 40% by weight of the surfactant, the content of other surfactants is decreased, so that the stycon may not be sufficiently washed. .

Among fatty acids having 8 to 18 carbon atoms or salts thereof, fatty acids having 8 to 18 carbon atoms are more preferable, fatty acids having 8 carbon atoms, fatty acids having 10 carbon atoms, fatty acids having 12 carbon atoms, At least one selected from the group consisting of coconut oil is more desirable, and at least one selected from the group consisting of caprylic acid, capric acid, lauric acid, and coconut oil is particularly desirable.
The above fatty acids are desirable from the viewpoints of availability, cost effectiveness, and handleability.

If the content of the fatty acid or salt thereof is less than 0.1% by weight of the surfactant, the detergent composition may not have sufficient foaming power and may have poor cleaning power. On the other hand, even if the content of the fatty acid or a salt thereof exceeds 40% by weight of the surfactant, there is no significant effect on the improvement of foaming power. Further, when the content of the fatty acid or the salt thereof exceeds 40% by weight of the surfactant, the content of other surfactants is decreased, so that the stycon may not be sufficiently washed. .

As the cleaning agent, it is desirable to use the cleaning composition for stycon of the present invention as a stock solution.
Moreover, it is preferable that the usage-amount of a cleaning agent is about 10 mL with respect to 1 m < ² >.

After being left for several minutes, the steam operation of the stipon is performed for about 15 minutes, whereby the steam is sprayed into the chamber where the cleaning agent is applied. With this steam, dirt adhering to the wall surface in the warehouse can be lifted.

After the steam operation is completed, rinse the inside of the cabinet with water using a hose or the like to wash away the dirt that has floated, and drain the wastewater into the drainage pipe.
As described above, HT pipes (heat-resistant hard polyvinyl chloride pipes) are often used as drainage pipes for stipons.

Further, when the dirt is so severe that it cannot be removed from the inside of the cabinet, the application of the cleaning agent, the operation of the stycon, and the rinsing operation may be repeated.

In the cleaning method for stycon of the present invention, even if the drain pipe is an HT pipe, the stycon can be sufficiently cleaned while suppressing the deterioration of the drain pipe. However, the drain pipe is not limited to the HT pipe, and may be a polyvinyl chloride pipe.

Examples that more specifically describe the present invention are shown below. In addition, this invention is not limited only to these Examples.

(Examples 1-4 and Comparative Examples 1-2)
With each compounding component shown in Table 1, Examples 1 to 4 and Comparative Examples 1 to 2 were prepared as stycon cleaning compositions. Moreover, about the cleaning composition for stipons of Examples 1-4 and Comparative Examples 1-2, it evaluated each as follows.
In addition, the unit of the numerical value in Table 1 is weight%.

(2) Detergency Soybean white squeezed oil is applied on a stainless steel plate surface of 197mm x 138mm in size, and this is heated at a temperature of about 200 ° C for 2 hours to polymerize and alter the oil stain. Was generated. Next, thin paper (20 mm × 20 mm large) was placed on the soiled surface, about 0.5 g of a stock solution of a cleaning agent was dropped on the stained surface, left for about 5 minutes, and then the thin paper was removed. The cleaning effect in this case was judged visually according to the following criteria. When the stain removal was fast and good, ◎, when the stain removal was good, ○, when the stain was uneven, Δ, and when the stain was hardly removed, ×.

(3) Influence on material HT piping material (heat-resistant hard polyvinyl chloride pipe, thickness 0.5 mm) was immersed in a container containing a stock solution of a cleaning agent. After being left in a 40 ° C. incubator for 14 days, the HT piping material was removed from the container and rinsed with water. The influence on the material was visually judged according to the following criteria. ◎ when there is no change compared to before the start of the test, ○ when it is slightly altered compared to before the start of the test, △ when it is significantly altered compared to before the start of the test, △, clearly altered compared to before the start The case where the prototype was not retained was marked as x.
