Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a deodorant composition,
More specifically, the present invention relates to an inexpensive and safe deodorant composition that suppresses and eliminates 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 a bad odor or an offensive odor, one of a sensory deodorant method, a physical deodorant method, a chemical deodorant method and a biological deodorant method is adopted depending on the type. There is.

For chlorine odor, a physical deodorizing method using activated carbon, which is an adsorption method, is used as a measure against drinking water and factory exhaust gas, and a certain effect is obtained.

By the way, microbial treatment is indispensable for preventing adverse health and aesthetic effects due to microbial contamination of molds, algae, etc. adhering to buildings and for adjusting the groundwork in repainting.

[0005] However, in the case of using sodium hypochlorite or a salicis liquid for spraying for the removal of microorganisms which generate putrid odors, and for the removal of molds and algae which adhere to the structure and spoil the appearance and damage the material, There is a problem that it is difficult to adopt the physical deodorant method because of diffusion. That is, even if the step of sterilizing and bleaching with an aqueous solution of sodium hypochlorite can be sufficiently performed, it is difficult to take measures against the chlorine odor that is scattered in the form of mist or gas, and sufficient environmental measures can be taken. It is not possible, and complaints are generated from the neighborhood.

[0006]

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 available chlorine of an inorganic chlorine compound having a chlorine odor, It is an object of the present invention to provide an inexpensive and safe deodorant composition without using an expensive bactericidal or algicidal agent.

[0007]

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

That is, the deodorant composition of the present invention comprises an inorganic chlorine compound having a strong chlorine odor, a deodorant, an aromatic substance and a surfactant.

The deodorant contains flavonoids extracted from plant leaves, and the aromatic substance contains plant essential oil distilled by steam distillation of the plant. The surfactant is sodium polyoxyethylene alkylphenyl ether sulfate.

According to the deodorant composition of the present invention, the deodorant and the surfactant suppress the strong chlorine odor by controlling the volatility, that is, the vapor pressure, without reducing the effective chlorine amount of the inorganic chlorine compound. Alternatively, it is possible to deodorize, and it is possible to improve the work environment by eliminating the aroma and odor balance due to the aromatic substance (fragrance) and the dislike of aroma due to taste.

Examples of the inorganic chlorine compound include sodium hypochlorite (NaClO), high-grade coconut powder [Ca (Cl
O) ₂ · CaCl ₂ · 2H ₂ O] aqueous solution having a strong chlorine odor is used.

The deodorant preferably contains flavonoids extracted from plant leaves.

From the viewpoint of improving the working environment, the aromatic substance contains a plant essential oil distilled by steam distillation of a plant in order to prevent an aversion from being caused by the balance of aroma and odor and taste of aroma. What you do is the best.

As the above-mentioned surfactant, sodium polyoxyethylene alkylphenyl ether sulfate among anionic surfactants is used for the purpose of not reducing the effective chlorine amount of the inorganic chlorine compound.

Embedded image What contains is used.

Sodium hypochlorite (NaClO) as the above-mentioned inorganic chlorine compound, high-grade coconut powder [Ca (Cl
_{O) 2 · CaCl 2 · 2H} 2 O] aqueous solution or the like are generally oxidizing power is strong, not only reduces the effective amount of chlorine by decomposition when adding organic matter, odor ether odor or the like instead of the chlorine odor May be present.

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

[0017] It is said that the natural world always maintains a constant environment and also performs a purifying action against a bad odor. Based on this idea, we have developed a natural deodorant extract as a deodorant, using an extract of tea leaves (green tea) that is familiar to humans and has been used for a long time.

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

On the other hand, the components of various malodors are volatile substances, which are composed of respective compounds or mixtures thereof, and have different feelings depending on their vapor pressure and amount.

The component of chlorine odor, which is said to be a foul odor, is a gas which has a small molecular weight, a low boiling point, and is easily vaporized into the atmosphere.

Flavonoids do not mask offensive odor components like aromatic deodorants, but wrap the chlorine odor components by physical or chemical action, or form adducts in the air. Eliminates foul odors by suppressing the volatilization.

Such deodorants are extracts from the leaves of plants and are obtained as a mixture. In order to find a type that has these deodorizing effects and is durable against the oxidizing power of inorganic chlorine compounds, tea leaves (green tea), cedar, pine,
Extracts from persimmons were separated into chlorophyll part, essential oil part, flavonoids, and residue part, and combined with inorganic chlorine compounds, only flavonoids had a stable deodorizing effect. However, the effect was recognized when the effective chlorine amount was a low concentration of 1.0% or less.

The tea leaf (green tea) extract includes flavonoids (epigalocatechin 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 and essential oils, and has a deodorizing effect even when used alone.

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

Further, the anionic surfactant was selected in order to stabilize the effective chlorine amount at a high concentration without decreasing it because the plant extract originally contained an anionic substance. It is based on the understanding that flavonoids, which are deodorant components, are also stable.

Further, in the search for a surfactant capable of withstanding the oxidizing power of a chlorine compound, it was found by experiments that an anionic surfactant is slightly stronger than a cationic surfactant or a nonionic surfactant. by.

Therefore, a group described in Examples described later was selected from a large number of anionic surfactants, and as a result of the experiment, sodium polyoxyethylene alkylphenyl ether sulfate was selected. Especially 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, flavonoids as an organic deodorant and polyoxyethylene alkylphenyl ether sulfate which is an anionic surfactant excellent in wetting, emulsifying, dispersing, washing, solubilizing, foaming and the like. In addition to the good compatibility of these three factors, sodium was capable of emulsifying and dispersing against inorganic chlorine compounds with strong oxidizing power, and also deodorizing the volatility of the inorganic chlorine compounds, that is, the vapor pressure. It is presumed that the components and the anionic surfactant were controlled.

However, it has been found from experiments that the oxidizing power of chlorine compounds, deodorant components and anionic surfactants also limit the balance of plant essential oils with time. For example, in the storage results in a cold and dark place in the winter (atmosphere temperature of 15 ° C or less), chlorine odor was observed from more than 3 months after compounding, and in summer (atmosphere temperature of 30 ° C or more) from about 2 months after compounding. However, the amount of available chlorine decreases sharply after 7 months at winter temperature and 5 months at summer temperature.

Higher alcohol 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 activators. Triethanolamine, sodium polyoxyethylene alkylphenyl ether sulfate, sodium polyoxyethylene octylphenol ether sulfate, sodium polyoxyethylene nonylphenol ether sulfate, sodium polyoxyethylene lauryl ether sulfate, potassium alkyl phosphate, sodium alkylbenzene sulfonate , Sodium oleylmethyl taurate, 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 became possible to store in a cool dark place for 2 months with an effective chlorine amount of 9%.

In addition, from the working environment, aromatic substances (fragrances)
Since it is also necessary to add, it was sought to find a plant essential oil on the premise that the balance between aroma and odor and the aversion caused by taste preference are not caused.

Commercially available American turpentine oil, abies oil, star anise oil, scented oil, okochia oil, hiba oil, jasmine oil, eucalyptus oil, cinnamon oil, cedarwood oil, cassia oil, rosewood oil, bergamot oil,
Anise oil, balsam copapa bay oil, bergamot oil,
Calams oil, cananga oil, clove oil, eucalyptus oil, boiled oil, lavender oil, lemon oil, lime oil, lemongrass oil, neroli oil, mint oil, orange oil, peppermint oil, rose oil, rosemary oil, spearmint oil As a result of compatibility with inorganic chlorine compounds with the goal of 0.3% by weight of vanilla, etc., it was not enough by itself, but chlorine compounds with aroma could be obtained by the combination of deodorant and anionic surfactant. Was obtained.

When the above 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 dark place for 2 months. The ratio is 0.1 part by weight of anionic surfactant (sodium polyoxyethylene alkylphenol ether sulfate) and deodorant (flavonoids) to 100 parts of sodium hypochlorite (effective chlorine content 9%). And / or perfume as a fragrant substance (plant essential oil)
From the viewpoint of the effect, it is preferable to set it to 0.2 to 0.3 part.

Therefore, the deodorant, the perfume and the surfactant can be directly added to the commercial product (8% by weight) other than sodium hypochlorite, but sodium chlorite and sodium chlorate can be added. , Perchloric acid, sodium perchlorate, and high-grade coconut powder should be added in the above ratio after confirming the amount of available chlorine in the aqueous solution.

The stabilized chlorine dioxide solution (ClO ₂ ) is not suitable unless it is added and used within 1 hour.

The mixing order of the product of the present invention is such that if a predetermined amount of a chlorine compound is added to the diluting water and a surfactant, a deodorant and a fragrance are added in the process of mixing and stirring, the chlorine odor will not be generated even in the mixing step. The effect of suppressing the generation is obtained. Further, according to the product of the present invention, the chlorine odor was not perceptually felt, and the available chlorine was maintained without being extremely consumed by the organic matter.

Therefore, the treatment of microorganisms inside and outside the building can be carried out without any trouble.

EXAMPLES Examples of the present invention will be described below.

Example 1 In order to see the deodorizing effect of the deodorant, the following test was conducted.

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 10 female (female college students) panelists based on the 6-level scale shown in Table 1. Table 2 shows the evaluation results. The numerical values in Table 2 are the difference between the evaluation values before and after the addition of the deodorant (for example, when the odor level before addition of the deodorant is 5 and the odor level after addition of the deodorant is 1, the evaluation value is 4). It means that the larger the value, the greater the deodorizing effect. The residual chlorine amount in Table 2 is based on the industrial water test method and residual chlorine (JISK0101, 28).

It can be seen from Table 2 that the deodorizing effect of the green tea flavonoid part (effective chlorine amount 0.1% by weight, residual chlorine amount 0.098% by weight) is excellent.
