Description

DETAILED DESCRIPTION OF THE INVENTION: Industrial Application Field = The present invention relates to a deodorizing agent that exhibits a strong deodorizing effect against a wide range of unpleasant odors that cause environmental problems.

2. Prior art and its problems to be solved] In the past, not only work sites but also the surrounding environment have often been contaminated by odorous substances generated in various industrial fields. As a result, numerous environmental and public health problems have arisen.

In general, many substances are known to cause unpleasant odors, such as ammonia, trimethylamine, hydrogen sulfide, and methyl mercaptan.

In addition, unpleasant odors such as sweat odor, equipment, and livestock shed odor'7)
, fecal odor, etc. are not caused by a single causative substance;
The odor is a combination of several causative substances.

Traditionally, deodorants that mainly treat causative substances include:
There are deodorants that deodorize by adsorbing the causative substances, and deodorizers that act directly on the causative substances to destroy or change their odors. Activated carbon and silica gel are known as examples of the former. On the other hand, the latter deodorants include, for example, various oxides, aluminum compounds, zinc compounds, metal soaps, ethylene glycol, boron compounds, phenolic compounds,
Amine compounds, salicylic acid compounds, ester surfactants, chlorine compounds, aldehyde compounds, peroxides, and the like are known.

By the way, deodorants that directly act on the causative substance to destroy or modify the odor generally have a deodorizing effect in relation to a specific causative substance. The causative agent is examined and a deodorant corresponding to the causative agent is used in conjunction with the causative agent.

However, deodorants that are used together often cancel out their deodorizing effects, which has led to problems such as the need to use a larger amount of each deodorant than when used alone. . As a result, there were many economic disadvantages, such as the increased cost of deodorants.

[Purpose of the invention]

Therefore, the present invention aims to provide a deodorant that has a synergistic effect against a wide range of unpleasant odors and can exhibit the same effect even if the amount of each deodorant used is reduced. purpose.

In order to achieve the above object, the present inventors have made extensive studies and found that the above object can be achieved by constructing a deodorant from a specific glycine derivative and tea leaf extract, and have arrived at the present invention. It is something.

That is, the present invention provides the following: (1) General formula (I): R+ (NHCHzCt(z) fi (wherein, Ro represents an alkyl group having 8 to 16 carbon atoms; R2 represents a hydrogen atom or a C 8 to 16 alkyl group; , m is an integer of 1 to 4, n is 0.1 or 2), and (2) a tea leaf extract, as active ingredients. The present invention relates to a deodorant characterized by containing:

The present invention will be explained in detail below.

The glycine derivative used in the present invention has the above general formula (1
).

In the above formula (I), preferred examples of the alkyl group as R or R2 include an octyl group, a decyl group, a dodecyl group, a tetradecyl group, a hexadecyl group,
Examples include octadecyl group.

Further, m is preferably 2, and n is preferably O.

When using glycine derivatives in the form of salts, salts with hydrochloric acid, sodium hydroxide, etc. are preferably used.

Preferred specific compounds represented by the above general formula (I) include, for example, N-octyldi(aminoethyl)glinone, N-F decylaminoethylglinine, N-dodecylcy(aminoethyl)glycine-NN-di(octylaminoethyl)glycine, J rare aminoethyl) glycine, N-oftatecylaminoethylglycine, and its hydrochloride and sodium salt.

The tea leaf extract used in the present invention consists of tea leaves extracted. Tea leaf extracts can be used in various forms, including their concentrate form and dry powder form.

As rape leaves, common tea leaves, such as green tea (
Can be used as an official.

Tea leaf extracts are generally obtained by soaking tea leaves in a mixed solvent of water and ethanol.

The ratio of the mixed solvent is generally 20 to 8 in terms of ethanol concentration.
0% is preferred. The immersion time is preferably 5 to 20 hours.

The immersion temperature is preferably 10 to 50°C. Note that stirring during soaking is preferred as an efficient extraction method.

The blending ratio of glycine derivative and tea leaf extract is generally Il.
l~500:1, preferably 10:1~200:1
It is. Outside this range, the synergistic effect of both components cannot be obtained.

In addition to the above-mentioned two components, a solvent such as water or alcohol may be added as necessary.

〔Example〕

Hereinafter, the present invention will be explained in more detail with reference to Examples.

Example 1 The deodorizing effect of the deodorant of the present invention on trimethylamine, which is an unpleasant odor, was tested.

As a glycine derivative, N-dodecyldi(aminoethyl)glycine hydrochloride shown by the following structural formula was used.

C1□Hzs(NHCHHzCHz)z NHCHzCO
OH-HCl On the other hand, as a tea leaf extract, green tea (Sencha) 2
5 g was immersed in a mixed solvent of 50 parts of water and 50 parts of ethanol, and after shaking for 20 hours, the extract was filtered and used.

The glycine derivative and the tea leaf extract were diluted with water to the concentrations shown in Table 1 below, and placed in a vial with a capacity of 120 mA at a volume of 3 Qml.

Trimethylamine was added to the concentration shown in Table 1, and the vial was sealed.

Place the vial in a 30°C water bath, warm it for 10 minutes, and collect the gas in the head space of the vial using gas chromatography (G2800 manufactured by Yanagimoto Seisakusho) or a detection tube (@Gastic direct reading dust collector). ) The deodorization rate was measured.

The deodorization rate is expressed by the formula: % formula % (). Here, A indicates the amount of odor components in the head space when no deodorant is added, while B
indicates the amount of odor components in the headspace when a deodorant is added.

Table-1 Trimethylamine 300ppm From the above Table-1, the amount of glycine “a” for 1-limethylamine
It can be seen that the deodorizing effect appears synergistically when the B derivative and tea leaf extract are used together rather than when used alone.

Example 2 The deodorization rate of tri- and J-thylamine was determined in the same manner as in Example 1, except that N-)decyl(aminoethyl)glycine, which is represented by the following formula: % formula %, was used as the glycine derivative. I took the measurements. The results are shown in Table 2 below.

Trimethylamine 0 ppm Similarly to Example 1, it can be seen that a synergistic deodorizing effect can be obtained by using the glinone derivative and tea leaf extract together.

Example 3 Same as Example 1 except that methyl mercaptan was used as the unpleasant odor and N,N-di(octylaminoethyl)clinone sodium represented by the following 2: C8H,7NHCH□C112 was used as the glycine derivative. Similarly, the rate of deodorization of unpleasant odors was measured.

The results are shown in 1-3 below.

Table 3 Methyl mercaptan ppm From Table 3 above, similar to Example 1, the effect of using the glycine derivative and tea leaf extract in combination was obtained.

Example 4 The following two derivatives are C1o11z+(NHCllzCIMz NHCHzC
OO)I-HCj! The deodorization rate of methyl mercaptan was measured in the same manner as in Example 3 except that N-decyl (aminoethyl) glycine hydrochloride shown in Table 1 was used.

The terminals are shown in Table 4 below.

Table 4 Methyl mercaptan ppm From Table 4 above, it can be seen that similar to Example 3, the combined effect of the glycine derivative and tea leaf extract can be obtained.

Example 5 The same procedure as in Example 1 was carried out, except that butyric acid was used as the unpleasant odor, and N-octadecyl di(aminoethyl)glyphin represented by the following formula: % formula % was used as the glycine derivative. The deodorization rate of butyric acid was measured. The results are shown in Table 5 below.

ppm From Table 5 above, it can be seen that a synergistic deodorizing effect with respect to butyric acid can be obtained.

Example 6 As a chrysin derivative, N-octadecyl di(aminoethyl) 11 represented by the following formula: % formula %
The deodorization rate of butyric acid was measured in the same manner as in Example 5 except that non-sodium was used. The results are shown in Table 6 below.

table Above table From 6, Chrysin derivatives and tea leaf extracts Dairy acid ppm By using in combination with Synergistic as in Example 5 You can see that it has a deodorizing effect.
