[Industrial Application Field] The present invention has an excellent deodorizing effect on a wide variety of bad odors such as indoors, toilets, garbage, refrigerators, vehicles, livestock pens, animals, pets, and human sweat odors. It relates to deodorants that are natural extracts. [Prior Art] With the recent improvement in awareness of amenities-oriented lifestyles, complaints about bad odors tend to expand in scope and become more diverse. In order to meet these demands, there is a need for highly safe and effective deodorants. Currently, household deodorants are basically classified into the following three types. Adsorption method... Physical adsorption using activated carbon, etc. Chemical adsorption using a chemical adsorbent Absorption of chemical liquid... Absorption into oxidizing agent Absorption into liquid gel masking agent... Fragrance is supported on a porous carrier 〇 Liquid or gel fragrance methods are limited in deodorizing agents to target odor components, and cannot be said to be effective against a wide range of bad odors. In principle, the other methods cannot be expected to have a sufficient deodorizing effect. Furthermore, some medicinal solutions and drugs are toxic to humans and animals, and may be unsuitable for household use. In order to meet these demands, there has been a demand for the development of highly safe and more effective deodorants. The present invention aims to solve these problems, and has excellent effects against a wide variety of bad odors.
Moreover, the objective is to provide a highly safe deodorant. [Means for Solving the Problems] As a result of extensive research to achieve this objective, the present inventor has found that "extracted substances", that is, leaves and stems of grasses, are extracted from grasses using various solvents. and/or soak the skin in water, warm water, alcohol, ester, acid,
The present invention was completed based on the discovery that extracts obtained by extraction with alkali or ketone solvents alone or in combination are effective in deodorizing a wide range of bad odors. The grass family plants that can be used in the present invention include pampas grass, ogiapurasuki, ogargaya, megargaya, syringe, and pampas grass (also known as kaya). Aquatic plants such as reed, platypus, and cypress. Corn for food and feed. Furthermore, among the weeds, there are foxtail grass, golden foxtail, chikarashiba, dogweed,
Kazeweed, Todashiba, Ushiweed, Bedweed, Kofnagusa, Chigaya, Oat, Mutsuregusa,
These include plants such as japonica, japonica, japonica, ohi-shiba, mehi-shiba, sycamore, japonica, sycamore, and niwa-dust, grains such as rice, wheat, millet, and barnyard grass, and bamboo, bamboo, and bamboo plants. The deodorant of the present invention can be processed and used in various dosage forms, ie, sheet, aerosol, granule, powder, or paper, depending on the purpose and situation of use. The various formulations of the present invention obtained in this way can be used for industrial purposes such as human waste treatment plants, sewage treatment plants, garbage treatment plants, fish factories, feed and fertilizer factories, pig pens, cow pens, and poultry pens.
Commercial use such as septic rooms in hospitals, cafeterias, etc., as well as toilets,
Wide range of uses such as refrigerators, disposable diapers, sanitary napkins, garbage containers, masks, wallpaper, shoji paper, fusuma paper, futon covers, sheets, garbage bags, kitchens, lockers, insoles, shoe cabinets, wardrobes, sports bags, etc. It can be expanded to Hereinafter, after explaining the manufacturing method of the deodorant of the present invention by giving examples, we will explain how to produce the deodorant of the present invention in a deodorizing test. A comparison of deodorizing effects is shown.
In addition, it is desirable to adjust the pH of the extract to a range of 4 to 10 in relation to the post-treatment process. [Example] Deodorant manufacturing method Example 1 Fresh leaves of Kumazasa are collected, washed with water to remove dirt, and dried. The drying method is natural drying.
It is preferable for more than a day to a month. Crush 100g of dried Kumazasa leaves into a beaker from Step 2, add water from Step 1, and boil until the volume reaches 200ml. Repeat this boiling operation 5 times. The ultraviolet absorption spectrum of a 1/100 diluted solution obtained by filtering the brown extract and using this extract as it is as a deodorant is shown in FIG. Example 2 Fresh bamboo leaves were collected, washed with water to remove dirt,
Finely chop with a speed cutter. Put 200g of shredded bamboo leaves into a beaker 2, add 1 alkaline water adjusted to pH=9.0 with sodium hydroxide, and boil until the volume reaches 200ml.
This boiling operation is repeated twice, the brown extract is filtered, the pH is adjusted to 6.8 using tartaric acid, and this is used as a deodorizer. Example 3 Fresh leaves of Chimaki bamboo were collected, washed with water, and then cut into small pieces using a speed cutter. Place the chopped pieces in a mortar and beat with a pestle. After beating (with juice), 10 g was placed in a glass extractor and extracted for 15 hours using 60 ml of an extract consisting of 70 parts of deionized water with a pH of 4.5 and 30 parts of ethyl alcohol to remove the alcohol. Adjust the pH to 6.8 using bicarbonate of soda and use this as a deodorizer. In Examples 4 to 7 below, fresh leaves, stems, and/or skins of corn, yuzudama, japonica, reed, and kusayoshi were collected as preliminary preparations, and the dust was removed by washing with water and finely chopped using a speed cutter. I went behind. Example 4 Put 200 g of fine fresh leaves of each of the grasses shown in Table 1 obtained by pre-conditioning into a beaker 2, and add 1 acidic solution adjusted to PH = 5.0 with hydrochloric acid to make 200 ml. Boil until This boiling operation was repeated twice, the brown extract was filtered, and the pH was adjusted to 6.5 using sodium bicarbonate.
This product is used as a deodorant. Example 5 400 g of fine raw stems of each of the grasses shown in Table 1 obtained by pre-conditioning were placed in a beaker 2, and 1 alkali solution adjusted to PH = 10 with caustic soda was added to the beaker to make 300 ml. Boil until cooked.
Repeat this operation once, filter the brown extract, adjust the pH to 6.8 using tartaric acid, and use this as a deodorizer. Example 6 Fine fresh leaves of each of the grasses shown in Table 1 obtained by preconditioning were left to air dry for 15 days. 10 g of this dried leaf was placed in a glass extractor and extracted for 15 hours using 50 ml of an extract consisting of 60 parts of deionized water, 30 parts of ethyl alcohol, and 10 parts of acetone, and the alcohol and acetone were removed using sodium bicarbonate. Adjust the pH to 6.5 and use this as a deodorizer. Example 7 Rice straw and dried bamboo bark obtained by pre-conditioning were placed in a mortar and beaten with a pestle. After beating, open it in a vat and leave it for 3 days to air dry. 10 g of this dried leaf was placed in a glass extractor and extracted for 15 hours using 60 ml of an extract consisting of 30 parts of ethyl alcohol, 30 parts of acetone, and 40 parts of ethyl acetate. Separate the liquid using a liquid funnel,
Obtain the extracted material transferred to the aqueous layer. An aqueous solution of this extract was added using sodium bicarbonate.
Adjust the pH to 6.5 and use this product as a deodorant. The ultraviolet absorption spectrum of the 1/100 diluted solution is shown in Figure 2. The extracted substances obtained in Examples 1 to 7 were all
It showed strong ultraviolet absorption spectra around 275nm and 194nm, and the ultraviolet absorption spectra did not change even if the extraction method was changed. Therefore, it is presumed that the same substance exists in the extracted substances and that this substance acts effectively in deodorizing a wide range of odor components. Deodorizing effect confirmation test (a) Preparation of deodorizing liquid The deodorizing liquid of the present invention is prepared by mixing 5 parts of the extracts of Examples 1 to 7, 15 parts of ethyl alcohol, and 80 parts of deionized water. (b) Test method Three types of foul-smelling samples were used: rotten garbage water, rotten fish water, and sewage sludge water. Take 50 ml of a foul odor sample, put it in a 500 ml stoppered flask, add 20 ml of water and glyoxal instead of the deodorizing solution obtained in (a) above or the deodorizing solution to this flask, shake vigorously for 10 minutes, and then Leave for 1 hour. A sensory test was conducted on each sample using a panel of five people with normal sense of smell. The evaluation is shown below 6
Comparisons were made using the average values of five panelists based on a graded odor intensity display table.
