Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an antifouling deodorant, and more particularly to an antifouling deodorant for urine bottles containing an acidic substance as an active ingredient.

By using the antifouling deodorizer of the present invention, it is possible to prevent the generation of bad odor from the urine bottle and the urine bottle from becoming dirty, to suppress the breeding of grouper terriers, and to keep the urine bottle hygienic as it is easy to clean. It can be suitably used in hospitals, nursing homes, and homes with bedridden patients and elderly people.

[Conventional technology]

In hospitals, cleaning with strong acids such as hydrochloric acid and disinfection with chemicals are used to clean urine), but at home, it is common to wash with water or use synthetic detergents.

On the other hand, as a deodorizing agent for human urine on board ships, glyoxal aqueous solution (see JP-A-48-098042), sorbic acid, salicylic acid, dehydroacetic acid, benzoic acid, or a mixture of glyoxal and a salt thereof (JP-A-50 -12
No. 6825), etc. are known, and sulfuric acid and its compounds have been used since ancient times to deodorize human waste.

However, no drug is known for preventing stains or deodorizing urine bottles.

[Problem that the invention seeks to solve]

Urinary bottles are often used by bedridden patients, elderly people, hospitalized patients, etc., and have a relatively complex shape to prevent urine from overflowing.

On the other hand, urine is decomposed by the action of microorganisms, producing a foul odor and producing insoluble decomposition products. This insoluble decomposition product is a mixture of calcium compounds and organic matter, and it firmly adheres to the wall of the urine bottle, and due to the complicated shape of the urine bottle, it cannot be completely removed by normal cleaning methods. It is difficult to do so. Therefore, it produces a bad odor even when not in use, and since there are microorganisms that decompose urine in the attached leta, when it is used, it decomposes the urine in a short time and generates a bad odor. Increase dirt adhesion.

SUMMARY OF THE INVENTION An object of the present invention is to provide a drug that prevents the generation of bad odors from urine bottles and the soiling of urine bottles.

[Means for solving problems]

As a result of intensive research to achieve the above object, the present inventors have discovered that by putting an appropriate amount of an acidic substance into the urine bottle in advance or immediately after use, it is possible to prevent the generation of bad odors from the urine bottle and the staining of the urine bottle. They discovered this and completed the present invention.

The present invention is an antifouling and deodorizing agent for urine bottles, which is characterized by containing an acidic substance as an active ingredient.

In the present invention, an acidic substance is a substance whose aqueous solution has a pH of 7 or less, preferably 5 or less.

For example, hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, boric acid.

Inorganic acids such as pyrophosphoric acid, metaphosphoric acid, sulfamic acid, sodium hydrogen sulfate, potassium hydrogen sulfate.

Acid salts such as ammonium hydrogen sulfate, salts of strong and weak acids such as ammonium sulfate and aluminum sulfate, acetic acid, oxalic acid, gluconic acid, malic acid, maleic acid, fumaric acid, succinic acid, citric acid, and tartaric acid.

Organic carboxylic acids such as adipic acid, isophthalic acid, hydroxyacetic acid, salicylic acid, benzoic acid, gallic acid, ascorbic acid, nitrilotriacetic acid, and acetic anhydride.

Examples include acid anhydrides such as maleic anhydride and phthalic anhydride, organic sulfonic acids such as Hensensulfonic acid and para-toluenesulfonic acid, and cyanuric acid.

In particular, considering that it will be used by unspecified patients, nurses, etc., acidic substances that have little oral effect and are registered as food additives or pharmacopoeia, such as phosphoric acid, acetic acid, gluconic acid, malic acid, Preferably, fumaric acid, succinic acid, citric acid, tartaric acid, adipic acid, ascorbic acid, etc. are used.

The antifouling and deodorizing agent for urine bottles of the present invention contains 0.1 to 5 g of at least one acidic substance as an active ingredient for one use of about 700 m1 of urine bottles, and its dosage form There are no particular restrictions. For example, liquid agents, paste agents, powder agents, granules, gunpowder, tablets, etc. can be employed. In particular, gunpowder and tablets are preferred because they can be easily put into a urine bottle.

If desired, various additives can be added to the antifouling and deodorizing agent for urine bottles of the present invention. For example, fragrances, deodorants,
A bactericidal agent, a chelating agent, a surfactant, a pigment, a binder, a lubricant, a disintegrant, a dissolution rate regulator, etc. are added depending on the dosage form.

The purpose of the fragrance is to mask the slight smell of urine, and various natural and synthetic fragrances are used.

The deodorant is intended to further improve the urine deodorizing effect, and water-soluble human waste deodorizers such as glyoxal and 2°3-dihydroxydioxane can be used.

Disinfectants are used to prevent the growth of germs and putrefaction in urine.

The purpose of adding a chelating agent is to chelate metal ions contained in urine, such as calcium ions, and to prevent the formation of water-insoluble compounds, ie, pollutants. For example, ethylenediaminetetraacetic acid, nitrilotriacetic acid, etc. are used.

The surfactant is used for the purpose of preventing the urine bottle from leaking due to organic matter. For example, nonionic surfactants such as polyoxyalkylene ether and ethylene oxide-propylene oxide block copolymer are preferably used.

Dyes are used to mask the color of urine. As for colors, primary colors have a large masking effect,
A blue color with a clean feel is preferred, and blue No. 1, methylene blue, etc. are preferably used.

Binders are used when forming into granules, powder, tablets, etc. These binders include polyethylene glycol (PEG), polypropylene glycol (PPG)
, water-soluble polymers such as hydroquinepropyl cellulose (+-IPc), polyvinylpyrrolidine (PP), and the above-mentioned surfactants.

A lubricant is used for the purpose of improving tableting properties when compressing gunpowder, tablets, etc. As the lubricant, calcium stearate, talc, etc. are preferably used.

Disintegrants are used for the purpose of promoting dissolution of gunpowder, tablets, etc. in urine. As a disintegrant, carboxymethylcellulose calcium (CM C-Ca), sodium bicarbonate, boric anhydride, etc. are used.

A dissolution rate regulator is used for the purpose of adjusting the dissolution rate of gunpowder, tablets, etc. in urine. As a dissolution rate regulator,
Water-insoluble sublimable substances such as barajichlorobenzene, the water-soluble polymers mentioned above, and the like are used.

The antifouling and deodorizing agent for urinals of the present invention is used by putting a predetermined amount into the urinal before or immediately after using the urinal. For example, in the case of liquids and powders, a method is to measure and add a predetermined amount using a measuring spoon, and in the case of powders and granules, one package of the product is filled with the amount for one use. In the case of gunpowder or tablets, there are two methods:
It is possible to adopt a locking method in which one tablet is molded to be used once and one tablet is inserted. The acidic substances in the gunpowder and tablets that are injected one moment at a time preferably have a solubility in water at 20°C of 3 g/100 gHzo or more, such as dl-malic acid, maleic acid, Mite M, citric acid. , succinic acid, etc. and mixtures thereof are preferably used.

In addition, acid gunpowder, tablets, etc. that have a slow dissolution rate of /8, such as fumaric acid and benzoic acid, and slow-dissolving gunpowder, tablets, etc. that have a dissolution rate regulator added can be used multiple times by putting them into the urine bottle once. can do.

In addition, the stains on the urine bottle can be removed by pouring the antifouling deodorizer for r; can.

[For production]

The antifouling and deodorizing agent for urine bottles of the present invention is characterized by containing an acidic substance as an active ingredient, as described above.

Urine excreted into a urine bottle is decomposed by microorganisms to produce ammonia, and its pH increases in a short period of time. on the other hand,
Calcium ions and phosphate ions contained in urine react to form highly alkaline water i18? (It produces an insoluble salt in l, and a mixture of this salt and indecomposable liquid adheres to the wall of the urine bottle as lη stains.

Therefore, by adding acidic substances to this system,
As a result of suppressing the increase in urine pH, precipitation of calcium salts is prevented. Furthermore, neutralization of ammonia with acid prevents the generation of ammonia odor. In addition, urine p
By lowering H, the proliferation of various bacteria is suppressed, the occurrence of putrid odor can be prevented, and the transmission of diseases through urine bottles can be prevented.

The amount of movement of the acidic substance to produce the above effect varies depending on the type of acidic substance, but is about 700 mj! The amount ranges from 0.1 to 5 g for one use of a urine bottle.

Most of the bad odor generated from urine can be removed by preventing the generation of ammonia odor as described above, but it is difficult to remove the odor of undecomposed organic matter using only acidic substances. Therefore, it is preferable to use a fragrance to mask this odor and a deodorizer to deodorize it.

In addition, although it is possible to prevent the formation of insoluble salts by using acidic substances, it is difficult to completely prevent undecomposed organic substances from adhering to the walls of urine bottles, so they are used as general cleaning agent ingredients. It is preferable to use a chelating agent, a surfactant, etc. in combination.

The dosage form of the antifouling deodorizer for urine bottles is generally tablets, which are easy to handle and allow a constant amount to be put into the urine bottle, but when used by professionals such as nurses, liquid formulations and tablets are preferred. etc. may be used.
