Description

Detailed Description of the Invention [Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleansing agent for human waste, which can prevent a bad odor generated from human night soil such as a storage type, circulating type or portable type toilet and human night soil.

[0002]

2. Description of the Related Art Conventionally, homes, buses, trains, trains, ships,
In toilets such as aircraft, circulation type, portable type, etc., and livestock farms, when human waste has a high concentration, human waste has been stored for a long period of time, or the temperature has risen, human waste rots and has a bad odor. To occur.

In order to deal with this, various deodorants are known.

For example, fragrances for masking malodorous components and agents that react with malodorous components have been used. In the former, it is difficult to completely remove the source of the malodor, and in the latter, the drug that reacts with the malodorous component is consumed up quickly, and a long-term deodorizing effect cannot be expected.

Further, bis (1-oxy-) is used as a bactericidal agent which decomposes undigested proteins, undigested fat and uric acid in human urine to suppress the growth of microorganisms causing an offensive odor.
2-pyridyl) disulfide (hereinafter referred to as "compound X"), N-dimethyl-N'-phenyl- (N'-florodichloromethylthio) -sulfamide (hereinafter referred to as "compound Y"), 2-pyridinethiol-1-oxide (Na salt) (hereinafter referred to as "compound Z") and the like are used (JP-B-56-7433 and JP-B-56-3).

As a result, the solubility may be deteriorated or the urine may be adsorbed to the urine to lose the bactericidal effect and the deodorant effect may not be exerted.

On the other hand, 2,2-dibromo-2-nitroethanol (hereinafter referred to as "compound A") and 2,2-dibromo-2-nitro-1-methylethanol (hereinafter referred to as "compound B") are industrial sterilizers. Agent (JP-A-1-102004

DISCLOSURE OF THE INVENTION The present invention is an alternative to conventional drugs, which has a deodorant effect excellent in the malodor of human waste without being affected by the chemical properties of human urine and has a residual effect. The purpose is to provide a deodorant.

[0009]

[Constitution of the invention]

In order to achieve the above object, various studies have been made on deodorants which are highly soluble in human waste in each pH range from acidic to alkaline and which are not adsorbed by human urine. As a result, dibromo- represented by the following formula (1)
It has been found that nitroalcohol compounds have an excellent deodorizing effect and residual effect on human waste.

That is, the gist of the present invention is

[0011]

Embedded image General formula (1)

[0012] A cleansing agent for human waste, comprising a dibromonitroalcohol compound represented by the formula (wherein R represents a hydrogen atom or an alkyl group) as an active ingredient.

Examples of the compound of formula (1) include 2,2-dibromo-2-nitroethanol and 2,2-dibromo-2-nitro-1-methylethanol.

The stability and solubility of the above compound A and compound B exemplified as the active ingredient of the present invention in an aqueous solution are as follows.

The stability of these compounds in an acidic aqueous solution is, for example, 40 ° C. in an aqueous solution having a pH of about 3 with malic acid.
The decomposition rate after standing for about 2 months is only about 0.1%, and its solubility is the same as when acidic with water containing about 25% human waste and having a pH of about 8. It has a sufficient bactericidal effect because it dissolves to a certain concentration and the sterilizing power is reduced to about 0.3% even after 24 hours at 30 ° C.

The concentration of the compound of formula (1), which is the active ingredient of the present invention, in human waste is preferably 30 ppm or more, but is preferably 30 to 150 ppm from the viewpoint of deodorant effect and economy.

The active ingredient of the cleansing composition for human waste of the present invention comprises a suitable auxiliary agent such as a surfactant (polyoxyethylene alkylphenol ether which is a nonionic surfactant and polyoxyethylene alkyl or an alkylbenzene which is an anionic surfactant). Sulfonate, alkyl sulfate, etc.) and the like, and may be formulated into powders, liquids, granules and the like by a conventional method.

The human waste cleaning agent of the present invention exhibits excellent effects by itself, but if necessary, 2-hydroxyethyl-2-nitro-1,3-propanediol may be used in combination.

Further, in the case of producing the cleansing agent for night soil of the present invention, chemical agents that react with malodorous components, such as glyoxal, organic acids (malic acid, citric acid, etc.), perfumes that mask malodorous components, and night soil color are used. Concealing colorants (dye,
Pigments, etc.) may be added as necessary.

Next, examples and comparative examples of the night soil cleaner of the present invention will be given, but the present invention is not limited to the following examples.

In the examples, "parts" means "parts by weight".

INDUSTRIAL APPLICABILITY The detergent for human waste of the present invention decomposes undigested protein, undigested fat and uric acid in human urine without lowering solubility even when treated with human urine or adsorbed by human urine. Since it completely suppresses the growth of microorganisms that cause the generation of malodor, it has an excellent deodorizing effect and residual effect without generating ammonia gas or hydrogen sulfide gas. Therefore, the cleansing agent for night soil of the present invention is useful in a place where a bad odor is generated.
