DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a deodorant composition,
More specifically, the present invention relates to an inexpensive and safe deodorizing composition that suppresses and deodorizes chlorine odor without reducing the effective chlorine amount of an inorganic chlorine compound having a strong chlorine odor.

[0002]

2. Description of the Related Art Generally, for malodors and unpleasant odors, any of a sensory deodorization method, a physical deodorization method, a chemical deodorization method and a biological deodorization method is adopted according to the type. I have.

[0003] As a measure against drinking water and factory exhaust gas, an adsorption method using activated carbon, which is a physical deodorization method, has been adopted for chlorine odor, and a certain effect has been obtained.

[0004] By the way, the treatment of microorganisms is indispensable for preventing adverse effects on health and aesthetics due to microbial contamination of molds, algae, etc. attached to buildings, and for adjusting the groundwork in repainting.

[0005] However, when removing the microorganisms that cause putrefactive odor, or removing molds and algae that adhere to the structure and impair the aesthetic appearance and damage the material, when sprayed with sodium hypochlorite or salad solution, There was a problem that it was difficult to employ the physical deodorization method due to diffusion. In other words, even though the sterilization and bleaching process using an aqueous solution of sodium hypochlorite, etc. can be performed sufficiently, it is difficult to take measures against chlorine odor that is scattered in the form of mist or gas, and sufficient environmental measures can be taken. No, complaints arise from neighbors.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and deodorizes and suppresses the generation of chlorine odor without reducing the effective chlorine of an inorganic chlorine compound having a chlorine odor. An object of the present invention is to provide an inexpensive and safe deodorizing composition without using expensive germicidal and algicidal agents.

[0007]

Means for Solving the Problems In order to achieve the above object, the inventors of the present invention have conducted intensive studies, and as a result, added a deodorant, an aromatic substance and a surfactant to an inorganic chlorine compound having a strong chlorine odor. As a result, they found that the chlorine odor during use was deodorized and suppressed, and completed the present invention.

That is, the deodorizing composition of the present invention is obtained by adding a deodorant, an aromatic substance and a surfactant to an inorganic chlorine compound having a strong chlorine odor.

[0009] The deodorant contains flavonoids extracted from the leaves of the plant, and the aromatic substance contains plant essential oil distilled off by steam distillation of the plant. The surfactant is sodium polyoxyethylene alkyl phenyl ether sulfate

According to the deodorant composition of the present invention, flavonoids
Deodorants and surfactants containing chlorinated compounds can control or deodorize strong chlorine odor by controlling the volatility, that is, the vapor pressure, without reducing the effective chlorine amount of the inorganic chlorine compound, and can also use aromatic substances ( By using the fragrance, it is possible to improve the working environment by eliminating the balance between the fragrance and the odor and the aversion caused by the taste of the fragrance.

As the inorganic chlorine compounds, sodium hypochlorite (NaClO), high-grade powder [Ca (Cl
O) ₂ · CaCl ₂ · 2H ₂ O] aqueous solution or the like having a strong chlorine odor is used.

The deodorant preferably contains flavonoids extracted from plants .

From the viewpoint of improving the working environment, the aromatic substance contains essential oils obtained by distilling a plant by steam distillation in order to prevent the balance between aroma and odor and aversion caused by taste of the aroma. What you do is best.

Among the anionic surfactants, sodium polyoxyethylene alkyl phenyl ether sulfate is used to prevent the effective chlorine content of the inorganic chlorine compound from decreasing.

Embedded image Is used.

[0015] Sodium hypochlorite (NaClO) as the above-mentioned inorganic chlorine compound, high-grade salad powder [Ca (Cl
O) ₂ · CaCl ₂ · 2H ₂ O] aqueous solution generally has a strong oxidizing power, and when an organic substance is added, it decomposes not only to reduce the available chlorine amount, but also to give off an unpleasant odor such as ether odor instead of chlorine odor. May be presented.

Therefore, it is only necessary to prevent a bad smell from reaching the human sense of smell by the deodorant.

It is said that the natural world always keeps a certain environment, and also performs a purifying action against odor. Based on this idea, a natural extract having a deodorizing effect was developed as a deodorant, using an extract of tea leaves (green tea) which is particularly familiar to humans and has been used for a long time.

After that, development of utilization of various plants has been promoted,
Most plants have been considered for deodorants.

On the other hand, various malodorous components are volatile substances, each of which is composed of a compound or a mixture thereof.

The component of chlorine odor, which is said to be offensive odor, is also a gaseous substance which has a small molecular weight and a low boiling point and is well volatilized in the atmosphere.

The flavonoids do not mask the malodorous component like the aromatic deodorant, but wrap the chlorine odor component by the action of physical or chemical, or form the adducts and the like, so that the flavonoids in the atmosphere can be removed. Eliminates bad smell by suppressing volatilization.

Such a deodorant is an extract from plant leaves and is obtained as a mixture. In order to find a class that has these deodorizing effects and is resistant to the oxidizing power of inorganic chlorine compounds, tea leaves (green tea), cedar, pine,
Extracts from persimmons and the like were separated into chlorophyll, essential oil, flavonoids and residue, and combined with inorganic chlorine compounds. As a result, only flavonoids obtained a stable deodorizing effect. However, the effect was recognized at a low concentration of 1.0% or less effective chlorine.

Extracts of tea leaves (green tea) include flavonoids (epigallocatechin gallate, gallocatechin, kaempferol, quercetin, etc.), amino acids (glutamic acid, aspartic acid, etc.), organic acids (citric acid, succinic acid, etc.), Sugars (glucose, fructose, sucrose, etc.),
Contains chlorophyll, essential oil, etc., and has a deodorizing effect even when used alone.

These deodorizing actions are generally effected by addition, polymerization, condensation and inclusion of phenolic groups of flavonoids to nitrogen and sulfur compounds, neutralization by amino acids and organic acids, inclusion and adsorption by sugars.・ It is estimated to be due to chemical and physical effects such as dissolution.

The reason for choosing an anionic surfactant to stabilize it at a high concentration without reducing the amount of available chlorine is that the plant extract originally contains anionic substances. This is because we have found that flavonoids as deodorant components are also stable.

Further, when searching for a surfactant capable of withstanding the oxidizing power of chlorine compounds, it was found through experiments that anionic surfactants were slightly stronger than cationic surfactants and nonionic surfactants. by.

Therefore, one group described in Examples described later was selected from many anionic surfactants, and as a result of experiments, sodium polyoxyethylene alkylphenyl ether sulfate was selected. In particular, when the alkyl group is C ₈ H ₁₇
~C ₁₁ H _23, n values of the ethylene glycol group is those of 0 was found to best it has stable characteristics.

From these facts, it can be seen that flavonoids as organic deodorant components and polyoxyethylene alkyl phenyl ether sulfate which is an anionic surfactant excellent in wetting, emulsification, dispersion, washing, solubilization, foaming, etc. Sodium was able to counteract inorganic chlorine compounds with strong oxidizing power and emulsify and disperse, in addition to the good compatibility of these three, deodorization of the volatility of inorganic chlorine compounds, that is, the vapor pressure. It is presumed that the components and the anionic surfactant were controlled.

However, experiments have shown that the balance between the oxidizing power of chlorine compounds, deodorant components and anionic surfactants and vegetable essential oils is also limited over time. For example, in the results of storage in a cool and dark place in winter (atmospheric temperature 15 ° C or less), chlorine odors are observed from about 3 months after blending and in summer (atmospheric temperature 30 ° C or more) about 2 months after blending. However, the available chlorine amount suddenly decreases, and the available chlorine amount becomes zero after 7 months at winter temperature and 5 months at summer temperature.

Higher alcohols sodium sulfate, sodium lauryl sulfate, ammonium lauryl sulfate, triethanolamine lauryl sulfate, sodium polyoxyethylene lauryl ether sulfate, sodium polyoxyethylene alkyl ether sulfate, polyoxyethylene alkyl ether sulfate, which are anionic surfactants Triethanolamine, sodium polyoxyethylene alkyl phenyl ether sulfate, sodium polyoxyethylene octyl phenol ether sulfate, sodium polyoxyethylene nonyl phenol ether sulfate, sodium polyoxyethylene lauryl ether sulfate, potassium alkyl phosphate, potassium alkyl benzene sulfonate , Sodium oleylmethyltaurate, etc. It was selected polyoxyethylene alkylphenyl ether sodium sulfate from within the
This is in consideration of compatibility with inorganic chlorine compounds and stability of flavonoids.

As a result, it was possible to store in a cool and dark place for two months with an effective chlorine amount of 9%.

In addition, from the working environment, aromatic substances (fragrances)
Because of the necessity of addition of fragrances, a search was made for essential oils on the plant on the premise that a balance between odor and odor and aversion due to odor preference were not caused.

Commercially available U.S. turpentine oil, abies oil, star anise oil, aromatic oil, okotia oil, coconut oil, jasmine oil, eucalyptus oil, cinnamon oil, cedarwood oil, cassia oil, rosewood oil, bergamot oil,

Obtained.

When the deodorant, aromatic substance and anionic surfactant are mixed with an inorganic chlorine compound, the inorganic chlorine compound must be in the form of an aqueous solution.

Therefore, in the case of sodium hypochlorite, a mixture of a deodorant, an aromatic substance and a surfactant can be stored in a cool and dark place for two months. The ratio is 0.1 parts by weight of an anionic surfactant (sodium polyoxyethylene alkylphenol ether sulfate) and 100 parts by weight of deodorant (flavonoids) based on 100 parts of sodium hypochlorite (effective chlorine amount: 9%). And / or fragrance as aromatic substance (vegetable essential oil)
It is preferable to set the amount to 0.2 to 0.3 part from the viewpoint of the effect.

[0036] Therefore, for the salad liquid other than sodium hypochlorite, a commercial product (8% by weight) can be directly added with a deodorant, a fragrance and a surfactant. , Perchloric acid, sodium perchlorate, high-grade salad powder and the like are added at the above ratio after confirming the effective chlorine amount in the aqueous solution.

The stabilized chlorine dioxide solution (ClO ₂ ) is not suitable unless added and used within one hour.

The order of mixing the product of the present invention is as follows. A predetermined amount of a chlorine compound is added to dilution water, and a surfactant, a deodorant, and a fragrance are added in the process of mixing and stirring. The effect of suppressing occurrence is obtained. Moreover, according to the product of the present invention, the chlorine odor was not felt sensuously, and the effective chlorine was maintained without being extremely consumed by organic substances.

Therefore, it is possible to proceed with the treatment of microorganisms inside and outside the building without any trouble.

[0040]

Embodiments of the present invention will be described below.

(Example 1) The following test was conducted to check the deodorizing effect of the deodorant.

The correlation between each part of the plant extract and the chlorine odor and the amount of residual available chlorine were measured.

The odor was evaluated by panelists of 10 women (college female students) based on the 6 levels shown in Table 1. Table 2 shows the evaluation results. The numerical values in Table 2 represent the difference between the evaluation values before and after the addition of the deodorant (for example, when the odor level was 5 before the addition of the deodorant and the odor level was 1 after the addition of the deodorant, the evaluation value was 4). The higher the value, the greater the deodorizing effect. The amount of residual chlorine in Table 2 is based on the industrial water test method and residual chlorine (JIS K0101, 28).

It can be seen from Table 2 that the green tea flavonoid portion (effective chlorine content 0.1% by weight, residual chlorine content 0.098% by weight) has an excellent deodorizing effect.
