Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorant effective for deodorizing malodors, particularly odors such as active nitrogen compounds and active sulfur compounds.

[0002]

2. Description of the Related Art Conventionally, as an industrial or domestic deodorant, an aromatic agent that eliminates a bad odor by releasing another odor,
There are deodorants for removing the malodor itself, but most of them were aromatic compounds composed of aromatic compounds.

However, the odor is too strong to deodorize the odor of ammonia-based active nitrogen compounds such as toilet odors and the odor of mercaptan-based active sulfur compounds such as hair-perming liquids for hairdressing. Since it is not possible to deal with it, recently, the development of deodorant is progressing.

[0004]

However, among malodors, in order to deodorize the odors of the above active nitrogen compounds and active sulfur compounds, it is necessary to chemically react with the compounds and completely convert them into odorless compounds. It is extremely difficult, and even if it has a deodorant effect, it is temporary, and in many deodorants, the deodorant effect disappears completely within a few minutes after being neutralized by immediate effect. However, nothing was satisfactory.

In view of the above problems, the present invention is an improved deodorant, particularly a deodorant, which is extremely useful for deodorizing the odors of the above active nitrogen compounds and active sulfur compounds among malodors. It is an object of the present invention to provide a deodorant that is effective for and has a long-lasting deodorizing effect.

[0006]

The present invention takes the following technical means in order to achieve the above object.

That is, the deodorant of the present invention comprises an aliphatic dialdehyde and the formula R ₁ R ₂ N (CH ₂ —CH═CH ₂ ) n SO
₃ Na [wherein R ₁ and R ₂ are hydrogen atoms or 1 to 1 carbon atoms]
5 is an alkyl group, and n is a number from 1 to 70. ] And sodium aminoallyl sulfonate shown by these are contained as an active ingredient.

[0008]

[Function] Due to the addition reactivity of the aliphatic dialdehyde with ammonia and the like and the free radical reactivity of sodium aminoallyl sulfonate, the odorous groups can be completely saturated and neutralized. The amino group of sodium aminoallyl sulfonate reversibly reacts with the aliphatic dialdehyde to effectively suppress the amino group, and the synergistic effect of the amino group has a long-lasting effect on the deodorizing effect of sodium aminoallyl sulfonate. Retains sex.

Therefore, since it can be a deodorant having a stronger deodorizing effect especially for active nitrogen compounds and active sulfur compounds and having a considerably long lasting effect, active nitrogen compounds such as toilet odors and hair perming liquids for hairdressing, etc. When used in combination with a drug such as an active sulfur compound, it can be used after completely deodorizing the peculiar malodor of these drugs, resulting in a comfortable use effect.

EXAMPLE The deodorant according to the present invention is an active ingredient
An aliphatic dialdehyde having two dehydrate groups and a formula R₁R
₂N (CH₂-CH = CH₂) N SO₃Na [However,
R ₁, R₂Is a hydrogen atom or an alkyl group having 1 to 5 carbon atoms,
n is a number from 1 to 70. ] Amino allyl represented by
Sodium sulfonate, weight ratio, 35-65: 65
˜35, preferably 1: 1 mixed.
Of.

The aliphatic dialdehyde has the formula O =
The use of glyoxal, which is the simplest dialdehyde represented by CH-CH = O, is preferred, and the glyoxal includes active nitrogen compounds such as ammonia, amines, nitric oxide, and peptones, hydrogen sulfide, mercaptans, and sulfur oxides. , It reacts with active sulfur compounds such as dimethylsulfite to form odorless compounds.

The sodium aminoallyl sulfonate has the formula CH ₃ CH ₂ N (CH ₂ —CH═CH
₂ ) It is preferable to use sodium diethylaminoallylsulfonate having a molecular weight of about 2,500, which is represented by n SO ₃ Na, and the sodium diethylaminoallylsulfonate has a dipolar ability. In addition to reacting with active sulfur compounds, it has a deodorizing effect by reacting directly with halogen elements such as fluorine and bromine, which have an irritating odor, in the atmosphere.

By mixing the glyoxal and sodium diethylaminoallyl sulfonate, a synergistic effect of the two makes it extremely reactive to neutralize the odor to the above active nitrogen compounds and active sulfur compounds, especially ammonia, The odorant group can be completely saturated and the deodorizing effect can be made stronger.

Further, when the neutralization reaction works reversibly, glyoxal and sodium diethylaminoallylsulfonate each have a deodorizing effect. Therefore, in the reaction by mixing both, or in any of the individual reactions. A Japanese reaction has occurred, and this deodorant effect is not only very strong, but also
It can be about twice as long-lasting as when used individually.

In addition to the above examples, it is also possible to use succindialdehyde or the like as the aliphatic dialdehyde and sodium diamylaminoallyl sulfonate or the like as the sodium aminoallyl sulfonate. .

In the deodorant according to the present invention, the weight ratio of the aliphatic dialdehyde to sodium aminoallylsulfonate is 35 to 6 in the experiment (results omitted).
It is preferably within the range of 5:65 to 35, and when it is outside the range, not only the deodorizing effect but also the durability thereof is extremely deteriorated, which is not preferable.

The deodorant of the present invention having the above-mentioned structure can be appropriately used by installing the deodorant in, for example, a front door or a toilet, or by storing it in a spray type container. However, in addition, for example, ammonia-based active nitrogen compounds such as insect bites (particularly bee stings),
When used in combination with a mercaptan-based active sulfur compound such as a perm liquid having a unique malodor, it can completely deodorize the unique organic malodorous components possessed by the drug, such as insect bites and perm liquids. It makes it possible to use the drug very comfortably.

Furthermore, if the deodorant contains an aromatic agent or a fragrance, it is possible to completely deodorize the subtle odors of the outside air and then release the individual odors without any trouble. The odor of the fragrance or fragrance can be enjoyed purely, and it can be a deodorant having a fragrance action by the fragrance as well as a deodorant action.

Experimental examples showing the synergistic effect of the deodorant of the present invention will be described below with reference to an example of a deodorant obtained by mixing the glyoxal and sodium diethylaminoallylsulfonate at a weight ratio of 1: 1.

As an experimental method, first, a 7 liter glass closed container is kept at 30 ° C. and 50 wt%, a fan is rotated in the container, and a petri dish filled with the deodorant is placed directly under the fan. .

Next, an ammonia-based malodorous substance is injected with a syringe, and immediately after that (about 20 seconds later), the odor concentration (unit: ppm) is measured with a detector tube for 150 minutes.

Specifically, as the malodorous substance, 5 μl of 28% aqueous ammonia solution was used, and the deodorant was 10 g. The results of the experiment are shown in Table 1 below. As a control, a measured value using 10 g of water is used as Comparative Example 1 in which the deodorant is composed of only glyoxal, and Comparative Example 2 is used in which the deodorant is composed of only sodium diethylaminoallylsulfonate.

[0023]

[Table 1]

From the above results, the deodorizing effect of the deodorant on ammonia is much higher than that of the case of using only glyoxal, and especially after 20 minutes or more, the deodorizing rate is almost 100%. It turns out that odor is possible.

Further, compared with the deodorant consisting of sodium diethylaminoallylsulfonate, there is not much difference for the first 60 minutes, but beyond that, the deodorant consisting of sodium diethylaminoallylsulfonate is steadily increasing. It can be seen that the deodorant of the present invention does not deteriorate in deodorant rate even after 150 minutes, and has a very good sustainability, while it decreases.

Further, a sensory test was conducted under the above conditions. The results are shown in Table 2 below. In addition, as a test method, 25 people (15 men, 10 women) were targeted and asked to have each of the three types of deodorant enter the hair each time and have them compare. It was The evaluation was carried out in a 4-step system of: strong odor, odor, slightly odor, and no odor.

[0027]

[Table 2]

From the above results, the deodorant effect of the above deodorant on mercaptan is much higher than that of glyoxal alone or sodium diethylaminoallylsulfonate alone, and in particular its sustainability is very remarkable. Should.

From the above experimental results, with respect to the odors of active nitrogen compounds and active sulfur compounds, glyoxal or sodium diethylaminoallylsulfonate does not have a very specific deodorizing effect, but should be mixed. It can be seen that the effect is remarkably enhanced.

[0030]

The deodorant according to the present invention comprises an aliphatic dialdehyde and the formula R ₁ R ₂ N (CH ₂ —CH═CH ₂ ) n SO _2.
3 Na [wherein R ₁ and R ₂ are hydrogen atoms or 1 to 1 carbon atoms]
5 is an alkyl group, and n is a number from 1 to 70. ] Since it is composed of sodium aminoallyl sulfonate as an active ingredient, it is possible to remarkably enhance the deodorizing effect on the odors of active nitrogen compounds and active sulfur compounds by the synergistic effect of both. , The odor generating group can be completely saturated and the deodorizing effect can be made stronger.

In particular, the deodorant of the present invention has very long-lasting properties, and has 2-3 times longer lasting properties as compared with the case where the above-mentioned active ingredients are used individually.

Furthermore, for example, when the mixture is used with a drug which gives off a bad odor due to an active nitrogen compound or an active sulfur compound such as an insect bite drug or a perm solution, the bad odor can be completely deodorized. However, it is possible to use it very comfortably, and when it is used by mixing it with a fragrance or a fragrance, mixing of odors does not occur, so that it is possible to enjoy only the odor.
