In Korea, it has been actively developed to develop new products of herbal medicine and herbal medicine suitable for skin of Korean women by removing the main raw materials of cosmetics from imports.

Natural extracts used as raw materials for cosmetics generally have a base body odor of each ingredient. Natural cosmetics are usually mixed with various natural extracts, though skin, lotion, and functional products are different from each other. Here, various natural extracts Is mixed with each other to produce a unique odor of natural cosmetics.

These natural cosmetics-specific odors are accepted variously according to people, but they are accepted as unpleasant or odorous odors to most people. Even if cosmetics with good effect have a bad smell for these reasons, users hesitate to purchase Because it acts as an element, the cosmetics industry is conducting various research and development to reduce the odor of natural cosmetics.

As a method of reducing the odor of such natural cosmetics, currently, there is a method of diluting existing odors by applying a perfume to a natural extract using a perfume masking method, and a method of diluting an odor of a natural extract through a chemical treatment or a filter Is being used.

However, as described above, a relatively large amount of flavor must be used in order to eliminate the odor of the natural extract using only the fragrance masking method. Even in a very small amount of such flavor additive, inflammation reaction may be caused according to a person, There is a problem that the aroma of the flavor additive and the odor of the natural extract are changed to another odor.

In addition, when the odor of the natural extract is reduced through the chemical treatment or the filter as described above, there is a problem that the active ingredient in the natural extract is destroyed or removed as well.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. .

1 is a flow chart for explaining a method for reducing the odor of a natural extract according to an embodiment of the present invention.

As shown in FIG. 1, the method for reducing the odor of the natural extract according to the present invention is characterized in that the odor is reduced through three stages of odor reduction step, and then the odor of the natural extract is selectively Reduced and fragrant.

The method for reducing odor of a natural extract according to the present invention comprises the steps of vibrating a natural extract to separate particles of a causative agent and other organic particles in the natural extract using a quantum wave generator, A first odor elimination step of obtaining a natural extract whose material particles are reduced first; A second odor elimination step of distilling the natural extract obtained in the first odor elimination step to obtain a natural extract in which deodorization substance particles are reduced in a second order; And a third deodorization step of filtering the natural extract obtained in the second deodorization reducing step through a filter using activated carbon to obtain a natural extract in which deodorization substance particles are reduced to a third order.

A method for reducing odor of a natural extract according to the present invention comprises firstly vibrating a natural extract using a proton wave generator to separate particles of a causative substance or the like of the natural extract into other organic particles, The particles of the causative substance are aggregated among the particles of the causative substance to induce the particles of the causative substance to be in a large particle state, and by filtering the particles of the causative substance which are in a large particle state through the filter, A natural extract in which the particles are reduced can be obtained.

Further, the above-mentioned waves can use waves having a frequency in the range of 10 Hz to 200 kHz. The waves may be irradiated with waves of a single region or irradiated while varying the frequency of waves with waves of a plurality of regions, thereby sequentially separating and minifying the particles of the causative substance in the natural extract and other organic substance particles.

The second step of reducing the second odor of the present invention is a vacuum distillation step using a vacuum. The vacuum distillation is carried out at a temperature in the range of 30 to 70 ° C. If the amount is less than the above range, the time taken by the reduced pressure distillation may be prolonged or the offensive odor reduction may be insufficient, and in the case where it is high, the effective component may be removed in addition to the offensive odor component.

The vacuum distillation proceeds in a state in which the pressure is lowered to a state just before bubbling is generated in the interior of the wood vinegar at the above temperature. The pressure at this time may be in the range of 500 to 730 torr.

Thereafter, the third deodorization step is a step of adsorbing and reducing the off-odor components using activated carbon. The activated carbon can be made by carbonizing coconut shell, coal, wood, etc. at a high temperature, and there are a lot of fine holes inside. The activated carbon may be granular activated carbon, but it is not limited thereto, and it is also possible to use biological activated carbon. In the present invention, the preferable particle diameter of the activated carbon is 10 to 500 탆. The activated carbon is used in a ratio of 2 to 20 g per 100 ml of wood vinegar.

In the third deodorization step, the wood vinegar and activated carbon may be put into a single container and allowed to stand for a predetermined period of time, or may be stirred. The activated carbon treatment period is not limited, but it can be treated for one day or more, preferably for 5 or more days, and the activated carbon and the vinegar solution are mixed.

After the above step, the activated carbon is filtered using a filter such as filter paper to obtain a vinegar solution with reduced odor.

Hereinafter, the present invention will be described in more detail by way of examples.

- Example  -

As a natural extract for odor reduction, a stock solution of pine wood was purchased from Kangwon Charm Charcoal and used.

Example  One

(1) Quantum wave generating device (first odor reduction)

The first deodorization step was carried out by introducing 400 ml of the seedling solution into a quantum wave generator.

 The temperature and pressure at the time of the quantum wave were set to room temperature and normal pressure, and the frequency range of the quantum wave was sequentially examined by alternately repeating five frequencies out of the frequencies of 10 Hz to 20 kHz. The waves were transferred for a total of 30 minutes while repeating. The frequency of the investigated waves was changed in the order of 300Hz? 600Hz? 6000Hz? 12000Hz? 18000Hz. It was observed that some particles were formed in the vinegar after the above wave. The treated seedling solution after the above-mentioned quantum-wave transfer device was obtained from Hyundai Micro's No. 2 filter paper.

(2) Purge distillation (second odor reduction)

The stock solution of the pastes that had passed through the quantum wave generator was placed in a round bottom flask immersed in a thermostat maintained at 40 ° C, and the inlet of the flask was connected to a vacuum pump. The degree of vacuum by the vacuum pump was reduced by distillation for 30 minutes while adjusting the state of the vacuum pump by using a 3-way valve just before bubbling was generated in the vinegar inside the flask. The gas flowing out from the distillation tank was condensed by a condenser equipped with a cooling coil through which the cooling water passed and reduced.

(3) Activated carbon filtration (third odor reduction)

The crude herbage after the vacuum distillation was put into a flask such as fine activated carbon having a size of 200 mu m, and then allowed to stand at room temperature for 10 days.

After that, the filtered wood pulp was obtained by separating from activated carbon by using a filter paper.

Comparative Example 1

The purified vinegar solution is obtained by carrying out the above-mentioned (1) quantum wave generator (first odor reduction reduction) and (2) distillation distillation (second odor reduction reduction) in Example 1 above.

Comparative Example 2

The purified vinegar solution is obtained by carrying out the above-described (2) distillation (second deodorization) and (3) activated carbon (third deodorization) in Example 1 above.

Comparative Example 3

(1) Quantum wave generator (first odor reduction reduction) and (3) Activated charcoal (third odor reduction reduction) are performed in Example 1 to obtain purified wood vinegar.

Comparative Example 4

The undiluted pasture solution was used as it was.

EXPERIMENTAL EXAMPLE 1: Odor Reducing Sensitivity Test

With respect to the treated wood vinegar obtained in Example 1 and Comparative Examples 1 to 4, the presence or absence of odor was assigned to the shoe leather research institute, and the sensory evaluation was carried out according to the evaluation criteria shown in Table 1 below. Table 2 shows the results.

As a result of the test, the vinegar solution according to Example 1 showed a good sensory evaluation result in the level of 1% aqueous solution of glacial acetic acid. Therefore, it is considered that the purification method according to the present invention has an effect of effectively alleviating the sour odor.

Experimental Example 2:

The components contained in the vinegar obtained in Example 1 and Comparative Examples 1 to 4 were detected by GC-MS. The contents of benzaldehyde, 2-furancarboxaldehyde and acetic acid, which are considered to greatly affect the odor of the double wood vinegar solution, were quantitatively determined, and the amounts of benzaldehyde, 2-furancarboxaldehyde and acetic acid, Respectively.

As a result of the analysis by this experimental method, in Example 1 in which both the quantum wave generator, the vacuum distillation and the activated carbon filter were both performed, the detection amount of the substances classified as odor inducing component in the vinegar solution was considerably reduced. On the other hand, in Comparative Example 1 in which the activated carbon process was not carried out, a considerable amount of odor inducing component materials were still detected. Comparative Example 2 in which the step of generating a quantum wave is omitted, and Comparative Example 3 in which vacuum distillation is omitted, Although the amount was reduced, a large amount of odor inducing ingredients were still detected.

Experimental Example 3: Effect of cosmetic composition for prevention or alleviation of atopic symptoms

The composition of the cosmetic composition was prepared using the vinegar solution obtained in Example 1 and Comparative Example 4. The composition was applied to 20 persons (10 males, 10 females) between 20 and 50 years of age with atopic skin irritation All 5 men and 5 women were assigned to each 10 patients. No other products such as steroids, antibiotics, and antihistamines were used until 2 weeks before the start of the experiment.

Table 4 below shows the degree of improvement of the skin by applying the cosmetic composition prepared by using the vinegar obtained in Example 1 and Comparative Example 4 of the present invention to the subjects of the present invention for 3 weeks, three times a day for 7 weeks.

As shown in Table 4, the results of the evaluation of skin itching showed that the subjects of Examples 1 and 4 responded that the skin itching symptom was mostly improved, and Comparative Example 4 in which the smell-inducing component was not reduced to the wood vinegar The effect was not significant. Accordingly, it is considered that the active ingredient that affects the therapeutic effect on the atopic dermatitis in purified vinegar according to the present invention is not removed in each purification step, but only the component that causes the offensive odor is selectively reduced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, I will understand. Accordingly, the technical scope of the present invention should be defined by the following claims.
