Description

Manufacturing method of deodorant

The present invention is a method for producing a deodorant by using a vegetable raw material, the production of deodorant which concentrates the deodorant components by steam distillation, dry distillation and other methods by using the conifers, broadleaf trees, branches, leaves, etc. of specific plants described below It is about a method.

In general, the odor treatment method includes a method of adsorption found in activated carbon, a method of dissolving and removing water or other solutions, an incineration method, and a method of masking with a fragrance.

Another method is to remove odors by chemically combining with odor. One example is chlorine dioxide (CIO ₂ ). In this case, however, the concentration of chlorine dioxide is lowered to a maximum of 8 g / l due to the danger, and thus cannot be widely used.

Currently, the removal of odor generated in various industries, animal husbandry, and households, including waste treatment plants, is not easy and is of greatest concern.

The present inventors have conducted research on the fusion of various purifying actions in the plant system, and have succeeded in extracting the active ingredient of a specific plant, thus completing a method for producing a good deodorant. The deodorant action of the deodorant according to the present invention is not caused by a physical action, but by a chemical reaction occurring between the aromatic hydrocarbon acid and its salt with the odor.

However, the aromatic acid and its salts as components are not composed of a single component but consist of a specific group of aromatic acids and salts thereof. Therefore, it is not specific about chemical bonds with odors. Depending on the types of odor substances, complex salt formation, ionic defects, van der Waals bonds and other deodorizing chemicals are formed. It can be estimated to be due to.

As a result of the experiments of the inventors, the reaction energy of both is not so high, and it is considered that the bonds at the low energy level are combined to show the deodorizing effect.

To obtain the deodorizing effect of the invention, the leaves, branches, and stems of plants, which are the main ingredients, are suitable to pine, persimmon, cypress, flower, lily, and asteraceae. In the Japanese Warrior, Japanese Bamboo, chaff, and silane and Senjuran are more preferable in Liliaceae. In the production method, the raw materials are chopped, washed with water, and dehydrated to control moisture to extract components by steam distillation, dry distillation and boiling.

The method of selecting any of the above steam distillation, boiling, and distillation as the extraction method depends on the type of raw material, the harvesting time, and the water content, and may be distilled if necessary. Such extracts can achieve more advantageous results by working in an inert gas such as nitrogen gas or under reduced pressure to prevent oxidation. The obtained extract is searched, filtered, and the mixed concentration is adjusted.

As the screening material and filter agent, kaolin, activated carbon, and diatomaceous earth, which are generally used, are used, but lignite products containing humic acid may be used. Humic acid itself acts as a deodorant against any kind of odor and is effective as a deodorant used in search and filter media.

The deodorant obtained as the aqueous solution can be used in the form of a pasta, granules, or impregnated in paper, nonwoven fabric, sponge, or the like, in addition to the liquid application method such as spray method and evaporation method. In order to form a paste or granule, it can be made by mixing a deodorant in a ratio of 300-500 g with respect to 100 g of absorbent polyma (eg β-cyclodextrin).

It has a wide range of uses, such as when impregnated with deodorant in paper, nonwoven fabrics, felts, sponges, papers, etc. As a method of impregnating the feeder, an aqueous solution of a water-soluble polymer (polyethylene glycol, ethylene glycol, propylene glycol, hydroxyethyl cellulose, hydroxypropyl cellulose, methyl cellulose, etc.) is mixed with 0.05-1% of the deodorant. It is impregnated as a liquid.

The use of a water-soluble aqueous polymer solution can increase the impregnating amount of the deodorant in the feeder, and also has the advantage of controlling the amount of insecticide used.

Although the deodorant of the present invention is slightly scented, it is necessary to have the fragrance depending on the use such as household use. To this end, by adding 1-5% of the fragrance, it is possible to generate more fragrance without lowering the deodorizing effect.

An example is given next.

Example 1

Mercy

Pine needles, fir leaf fine bamboo, rice husk, mugwort, persimmon leaf 30g each wash, dehydrate, chop, put in 3l stainless steel container and put 1.5l of distilled water and cut off for 60 minutes. Remove the solids and continue to boil to 400 ml.

100 ml of 1% of fumic acid was added thereto, and 30 g of clay was added for the purpose of searching and filtration, and then filtered at low temperature to adjust the nonvolatile component to about 5% to obtain an aqueous solution of pH4.6.

Example 2

Steam distillation method

After distilling, dehydrating, and cutting off the leaves of pine twigs, fir twigs, leaves, chaff, lean, hemp, and silane, steam distillation by putting 10g each into a 1L steam distillation vessel. The extracts are concentrated to 50 ml each, and then mixed with 150 ml of 1% fumic acid extract obtained by heating extraction separately. This gives an aqueous solution of pH4.8.

Example 3

Drying method (1)

50 g of the same raw material as in Example 1 were put in a distillation apparatus having a capacity of 1 l and 10 l of water was added thereto. Nitrogen gas is injected and replaced with air in the vessel, and heating is started to dry it quietly. While continuing dry distillation, the distillation unit is kept under nitrogen atmosphere. 110 ml of the obtained extract was prepared to pH 4.4 by adding water to 240 ml.

Example 4

Carbonization method (2)

When an extract obtained in the same manner as in Example 3 added 45 ml of a 1% solution of humic acid extracted separately to about 300 ml, an aqueous solution of pH 4.3 was obtained. In order to compare the effect of the extract obtained in the above example, the aqueous phase and the superabsorbent polymer were adsorbed onto the cyclodextrin to form paste and granules to obtain the following experimental example.

Kitchen Litter Synthetic Resin Containers Amount of melted kitchen waste for about two days in 40 liters left for 2 days in summer and then sprayed once a day 10ml of the solution prepared according to the above method. 60 g of the paste was wrapped in a nonwoven fabric and attached to the lid of the container. The granular one filled up 12g each time the height of loading of kitchen trash was 20cm.

The results of the maid's response test are as follows.

In addition, by the aqueous solution test of aqueous ammonia and ethyl mercaptan

a) 0.1% ammonia water

b) 0.01% ethyl mer captan liquid

100 ml of a or b sample was put in a flask with a capacity of 1 l, the deodorant of Example was placed in a container, and the sample concentration of the container was waited and compared with the start of the detection tube for 24 hours. Deodorant was made into all the solution.

The application surface of the deodorant according to the present invention is wide and in order to comply with it, it can be used by impregnating into an absorbent polymer as well as an aqueous solution as well as paste, granular or nonwoven fabric and paper as described above. It is characteristic.

Absorbent forima was, for example, β-cyclodextrin.
