Description

TECHNICAL FIELD The present invention relates to a bath cleaning agent that can keep hot water clean for a long period of time by simply putting it in hot water in a bath. .

"Prior art" Conventionally, there are various bath additives such as bath additives and bath fragrances that can be enjoyed in various ways by giving aroma to or coloring the hot water in the bath. There is no bath detergent that can keep the bath clean for a long period of time and prolong the suitable period of use of the bath water.

"Problems to be solved" Some conventionally known bath agents have added agents such as bactericides that can clean the bath water, but the effect is Only for a short period of time after addition to, and not persistent. Moreover, since the bactericide added to the bathing agent is a well-known organic or inorganic compound, the bactericidal effect cannot be sufficient because the concentration cannot be made high for the purpose of use.

Therefore, up to the present, for example, in a family of three, when bathing every day, the bath water and bathtub have to be replaced and cleaned every day or several days.

“Means for Solving Problems” As is well known, it has long been known that copper and silver have a sterilizing action. For example, in hospitals, copper containers were used to store medical instruments, and in the Middle Ages, silver tableware was used to prevent food spoilage. No details are known about the sterilizing action of copper or silver, but it is clear that it is due to the activating action of these ions. In other words, the presence of 0.1 to 0.3 ppm of copper ions prevents the generation of most algae and silver ions.
It is known that the presence of 0.05 to 0.10 ppm kills E. coli in the water column.

Therefore, it is possible to provide a bath detergent using this silver, but not limited to this silver, usually metal ions are often obtained from a metal salt that is a compound of metal, and the elution rate of the metal salt is It is either slower or faster than the range suitable as a bath cleaning agent, and its speed cannot be controlled.

With respect to this problem, the inventors of the present invention have made intensive studies paying attention to the low-speed melting property of glass, and have obtained the following findings. That is, quartz glass is an ideal glass from the viewpoint of physical and chemical stability, but it does not melt at temperatures higher than 1700 ° C, so it is not practical for general use. As is well known, the glass that has been put into practical use is made easy to melt by adding a modified oxide such as soda (Na ₂ O) or lime (CaO) to silicic acid which is a network-forming oxide. The composition and structure make it easy to mold into various shapes. That is,
The covalent bond of the irregular network structure formed by the network-forming oxide is partially cleaved by Na ions, Ca ions, and the like. A typical glass having this structure is soda / lime / silicate glass, or simply silicate glass, which is used in glass products with the highest production volume and is available at low cost. Compared with quartz glass, the surface of this silicate glass is slightly violated by water and moisture. That is, it has low solubility in water. However, its dissolution rate is rather slow, and it is not suitable for controlling dissolution of bath detergent.

When a modified oxide is further added to the silicate glass, the covalent bond due to silicic acid is further broken and the network structure becomes a chain structure. A typical glass with this structure is
It is called soda / silicate glass, and because it is easily dissolved in water, it is used in the composition of water glass, which is often used as an adhesive or curing agent. When a modified oxide is further added to this glass, it becomes a covalently bonded silicate ion, and has a structure of an inverted glass with many ionic bonds. This reverse glass is easy to crystallize in the melting process and difficult to vitrify homogeneously, but it is relatively easy to homogenize it by substituting boric acid or phosphoric acid for part or all of the silicic acid which is a network-forming oxide. It can be a transparent glass.

Thus, the dissolution rate of glass in water requires physical and chemical examination of the process, but the dissolution rate can be controlled by appropriately selecting the composition of glass. As described above, such a glass is simply melted glass (Soluble Glass) or controlled elution glass (Contrble Glass).
olled Release Glass). This soluble glass can contain ions of a metal such as silver, which is an active ion effective up to about half of the constituent components, in a stable state, and by adjusting the melting rate of this glass, effective glass can be obtained. An appropriate amount of metal ions can be eluted at a constant rate from 1 hour to several decades. For example, as shown in FIGS. 3 (a), (b) and (c), when particles 1 of an active element (silver) -containing soluble glass having a controlled dissolution rate are put into water, silver in the glass particles 1 is converted into glass. Elute as ions at a constant concentration with the dissolution of. When the glass dissolution rate and the silver ion concentration at this time are respectively shown as a function of time,
It becomes like FIG. 4 (a) (b). (A) is a graph showing the change in the dissolution rate of soluble glass in a large volume of water, and (b) is a graph showing the change in the elution concentration of silver ions in a predetermined volume of water. Among these figures, the figure (b) in particular shows an important meaning. That is, it can be seen from this figure that the concentration of silver ions is always constant until the molten glass is completely melted.

As mentioned above, the dissolution rate of the soluble glass can be controlled because the glass is an amorphous and homogeneous material, and it is not necessary to control the dissolution rate with a water resistant material such as a coating material or a capsule. is there. In addition, the soluble glass is capable of binding with a large amount of metal ions, and generally does not leave a residue due to melting. Further, since the optimum dissolution rate can be selected, the elution of excess metal ions can be prevented, and the most efficient adjustment can be made while minimizing environmental pollution.

Further, this soluble glass has any shape, for example, powder, fibrous, flake-like, so as to suit the purpose of use.
It can also be foam glass, tubular, or block-shaped. Soluble glass has the advantages that it can be sufficiently produced by conventional glass engineering knowledge, has low environmental pollution, and has high added value.

Based on the above findings, when the optimum composition and particle size of the silver-containing glass agent as a bath cleaning agent was sought, the composition was as follows: B ₂ O ₃ ...... 40 to 76 wt% SiO ₂ ...... 20 to 56 wt% Na ₂ O …… 3 to 20 wt% Al ₂ O ₃ …… 1 to 5 wt% AgNO ₃ …… 0.2 to 2.0 wt% is preferable, and the particle diameter of the granules is 0.5 mm to 10c.
It was found to be m, preferably 1 mm to 5 cm.
