Description

  The present invention relates to a solid drainage pipe cleaning agent, and more specifically, drainage pipe cleaning that can sufficiently clean the entire drainage pipe interior and achieve the purpose of sterilization, bleaching, deodorization, washing, etc. It relates to the agent.

  Drainage outlets and the inside of drainage pipes in kitchens, washrooms, bathrooms, etc., grow with various germs as they are used, and are covered with slime-like materials, or dirt due to scales or the like. Conventionally, as a simple cleaning of such dirt, carbon dioxide gas is generated by reacting carbonate and organic acid in water, and this foam is brought into contact with dirt, In order to impart foaming properties, surfactants are blended, and oxidants such as chlorinated isocyanuric acid and halogenated hydantoin are blended into these to enhance cleaning power, sterilization, bleaching, deodorization, etc. Preparations for imparting are known. For example, a foaming detergent (Patent Document 1) combining a hydrogen peroxide addition compound, chlorinated isocyanuric acid and a surfactant, and a sterilizing detergent containing a chlorine-based disinfectant, an organic acid, a carbonate, and a surfactant (Patent Document 2) is disclosed and proposed.

  These foaming detergents are dissolved in foaming by contacting with water in the drainpipe trap after being put into the drainpipe, and the inside of the drainpipe is disinfected, bleached, deodorized, washed, etc. Yes, and those with a surfactant are used to wash the entire drainage pipe (especially the inlet side of the trap from the trap) by spreading the foam not only in the trap but also throughout the drainage pipe. It is.

  The above-mentioned conventional drain pipe cleaning agent is one that is left for a few minutes to several hours after being put into the drain pipe, and then washed and disinfected by flowing water. However, since the parts other than the vicinity of the trap of the drain pipe are sterilized and washed with foam containing a bleach component, if the foam duration is short, it will come into contact with dirt inside the drain pipe even if the standing time is extended. Since the cleaning time is shortened, sufficient cleaning or the like cannot be performed, and a bad odor may occur even after the cleaning. In addition, recontamination after cleaning is fast, and there is a problem that the drain pipe must be frequently cleaned.

  Accordingly, there has been a demand for the development of a drainage pipe cleaning agent that can cause the bleach component to act on the entire interior of the drainage pipe for a long time and can sufficiently clean the inside of the drainage pipe.

  As a result of intensive studies to solve the above problems, the present inventor found that the water-insoluble adsorbing component was added to the drainage pipe cleaning agent, and the bleaching agent component carried on the foaming agent even after the bubbles disappeared. It has been found that it adheres to the inner wall and dirt of the drainage pipe, bleaches for a long time, and can wash the entire drainage pipe.

  That is, the present invention is a solid drainage pipe cleaning agent characterized by containing a halogen bleach component, a foaming component, a surfactant and a water-insoluble solid adsorbing component.

  When the solid drainage pipe cleaning agent of the present invention is put into the drainage pipe, it collapses while foaming by reacting with the water in the trap of the drainage pipe, dissolves the bleach component in the trap water, Foaming with a surfactant can fill the entire drainage pipe with foam containing a halogen-based bleach component. At this time, the water-insoluble solid adsorbent remains in the trap in a state where the halogen-based bleach component is adsorbed, and spreads over the entire drainage pipe by bubbles and adheres to the inner wall and dirt of the drainage pipe. Even after the foam disappears, the solid adsorbent containing the bleach component remains on the inner wall and dirt of the drain pipe, and this solid adsorbent gradually releases the bleach component, thereby removing the dirt on the inner wall of the drain pipe. Acts for a long time and bleaches and cleans the inside of the water pipe.

  After that, when the drain pipe is washed away with water, the solid adsorbent remaining in the trap adheres to the dirt of the drain pipe behind the trap of the drain pipe while flowing out, and the bleaching agent component is gradually released there. Thus, the drain pipe can be cleaned.

  Thus, if the solid drainage pipe cleaning agent of the present invention is used, sufficient cleaning and bleaching can be performed over the entire drainage pipe.

  The solid drainage pipe cleaning agent of the present invention contains a halogen-based bleach component, a foaming component, a surfactant and a water-insoluble solid adsorbing component as essential components.

Foam and fill the entire drain pipe with foam containing a halogen-based bleach component. Therefore, the place where the water is always present, for example, a U-shaped trap is preferable. The foam foamed in this trap disappears in a short time, but the water-insoluble solid adsorbent contained in the foam remains adsorbing the halogen-based bleach component, and the drain pipe (especially the drain pipe on the front side of the trap). ) Adheres to the inner wall of the drainage pipe, acts on the inner wall of the drainage pipe for a long time, and cleans the drainage pipe. Then, after elapse of a predetermined time, for example, 1 minute to 12 hours, the drainage pipe (especially, the drainage pipe ahead of the trap) is washed down by washing with water to flow down.

  As described above, the method of the present invention can efficiently clean the inside of the drain pipe by utilizing the property that the solid adsorbent adsorbs the bleach component and the property that the solid adsorbent easily remains on the inner wall of the drain pipe. It can be done.

  EXAMPLES Hereinafter, although an Example is given and this invention is demonstrated in more detail, this invention is not restrict | limited at all by these Examples.

Example 1
Manufacture of solid drain pipe cleaner (1)
Ingredients shown in Table 1 below were weighed out in the indicated amounts and mixed thoroughly. Subsequently, this mixed powder was tableted with a press molding machine at 200 kgf / cm ² to obtain Invention Products 1 and 2 and a Comparative Product.

Example 2
Adsorption component transport and persistence test:
100 ml of 25 ° C. tap water was placed in a 300 ml graduated cylinder. Next, exposed cotton (14.5 cm × 9 cm) was attached to a plastic plate and placed in a graduated cylinder so that at least its lower end was 3 cm or more from the water surface. The inventive products 1 and 2 and the comparative product produced in Example 1 were respectively put into a graduated cylinder and foamed. After 30 minutes, the exposed cotton was taken out from the graduated cylinder and shaken 3 times with 1 L of tap water.

  Next, the exposed cotton is dried in a dryer at a temperature of 50 ° C. for 20 minutes, and the reflectivity of 5 cm, 10 cm and 15 cm on the interface of the exposed cotton is measured by a reflectometer (Tokyo Denki reflectometer). modelTC-6D; using filter G), and the residual amount of the adsorbed component was measured from the following calculation formula. The results are shown in Table 2.

  From the above results, it can be seen that Bincho charcoal, which is an adsorbing component, is carried from the lower part of the drain pipe (meas cylinder) to the upper part by the foam, and remains adhering thereto.

Example 3
Sterilization test of adsorbed components:
3 cm × 3 cm of the exposed cotton used in the test of Example 2 was cut out and used as a test piece. The test piece was placed on an agar medium coated with Pseudomonas aeruginosa (ATCC12689) and cultured at 36 ° C. for 24 hours. After culture, it was visually confirmed whether a growth inhibition zone (halo) was observed. The results are shown in Table 3.

  As shown in Table 3, in the cotton treated with the products 1 and 2 of the present invention, the occurrence of halo was remarkably observed, indicating the sterilizing power of SDIC. That is, it was shown that SDIC was adsorbed to the adsorbing component and its sterilizing power was maintained, and it was determined that the sterilizing action was obtained by the adsorbing component remaining in the drain pipe as well. On the other hand, in the comparative product 1, no halo was observed, indicating that no bactericidal power could be obtained without the adsorbing component.

Example 4
Bactericidal test of adsorbed component The product 3 of the present invention was produced in the same manner as in Example 1 with the formulation shown in Table 4 below. This was dissolved in 100 ml of ion exchange water with stirring. While the precipitated Bincho charcoal was washed several times with ion-exchanged water, it was naturally filtered with Toyo filter paper No2. Thereafter, the filter paper was dried with a dryer at 50 ° C., and Bincho charcoal on the filter paper was collected.

The collected Bincho charcoal (0.01 g) was dispersed in a working tube containing 10 ml of physiological saline, and 0.1 ml of Pseudomonas aeruginosa culture solution (about 10 ¹⁰ CFU (cells / ml)) was further added. As a control, 0.01 g of raw material Bincho charcoal was dispersed in 10 ml of physiological saline, and 0.1 ml of a Pseudomonas aeruginosa culture solution was similarly added. After 40 minutes, 0.1 ml each was taken out from the working tube, diluted 100 times, and then cultured on a normal agar medium at 36 ° C. for 24 hours. The number of Pseudomonas aeruginosa was confirmed and evaluated according to the following criteria. The results are shown in Table 5.

(Evaluation criteria)
Symbol content +++… Pseudomonas aeruginosa count 10 ⁴ CFU or more ++… Pseudomonas aeruginosa count 10 ² to 10 ⁴ CFU
+ ... ... Pseudomonas aeruginosa count 10 ² CFU or less-... ... No growth of bacteria

As is clear from this result, Pseudomonas aeruginosa is not detected from the dispersion solution of Bincho charcoal of the product 3 of the present invention adsorbing SDIC. It was confirmed that it was done.
