JPH09294806A - Controlled release solid deodorant - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a deodorant capable of simply continuing the deodorizing action of a malodor component without diluting it with water or spraying it by infiltrating a deodorizing component to a solid material, and gradually discharging it little by little. SOLUTION: A natural pyroligneous acid approved as a food additive is prepared, for example, and its solution is infiltrated into a porous solid material. Ultrasonic waves are utilized to facilitate the infiltration of the component, then the porous solid material is air-dried, and these actions are repeated as required. When a controlled release solid deodorant thus obtained is put in a simplified indoor toilet, for example, the deodorization effect can be expected over a long period while the component is gradually discharged. When the change of the degree of odor of 10%-aqueous ammonia, for example, is measured on the pumice serving as the porous solid material infiltrated with pyroligneous acid for the portable odor sensor ammonia odor for a long period to estimate the deodorization effect, it can be found via the comparison with a control that the ammonia odor can be removed very effectively.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a sustained-release deodorant solid material, more specifically, a fine porous solid material impregnated with a deodorant component to increase the surface area of the solid material. The deodorant component permeated and adsorbed on the surface is gradually released over a long period of time to enable deodorant over a long period of time, and it is possible to dilute or spray with water without polluting the air. The present invention relates to a sustained release deodorant solid substance characterized by not requiring it.

(Prior art and problems) Odor is at home, in the workplace, in public facilities, in public transportation such as trains, ships, aircraft, or in a highly sealed room, for example, the place of activity of human beings, such as in a submarine ship, It was a permanent issue that could occur in all. Therefore, many attempts have been made since long ago, but they have not been resolved yet, and even the deodorants currently used are products of chemical synthesis, which could contaminate the environment and air. Conventionally, two types of deodorants have been mainly used: a method of simply adsorbing a malodorous component such as activated carbon, and a method of masking the malodor by releasing other aroma stronger than the malodorous component. Since a sufficient deodorizing effect was not obtained, the odor for masking became a problem, and it was difficult to maintain the effect for a long period of time. In addition, it is easily thought that allergy due to trace chemical substances, which is a problem today because it is a product of chemical synthesis, has some adverse effects from the viewpoint of environment and air pollution, and its solution has been awaited.

(Means for solving the problem) Unlike the conventional methods for adsorbing malodor, such as activated carbon and masking malodor, and methods for adsorbing malodor on porous substances, deodorant components are finely porous. The present invention has completed the present invention by finding a method of adsorbing a small amount on a volatile substance and releasing it in a trace amount to chemically bond, decompose or neutralize a malodorous component such as ammonia or mercaptan. The deodorization mechanism was found to be effective for deodorization by chemically combining natural trees, crude drugs, flavonoids, flavones, and polyphenols contained in plants with malodorous components such as ammonia and mercaptans. It was devised to release a small amount of the ingredients of the product over a long period of time, and it was possible to maintain its deodorizing effect.

(Function) The surface area of the solid matter used is much larger than the size of the solid matter. Therefore, the deodorant component attached to and adsorbed on the surface is larger than conventional solid deodorants, and therefore the deodorant The speed and effect increase dramatically. Further, by making the deodorant component release gradually, the effect can be maintained for a long period of time.

(Example 1) 10 sustained release deodorant solids using wood vinegar
Deodorant for% ammonia odor. A natural wood vinegar solution approved as a food additive is prepared and the solution is permeated into the porous solid material. At this time, ultrasonic waves are used to facilitate the permeation of the components and increase the adsorption amount. After preferably continuing this for 30 minutes, the porous solid is air dried and this operation is repeated if necessary. This is made into a sustained release deodorant solid and put in a simple indoor toilet. The deodorizing effect can be expected over a long period of time with the sustained release of the ingredients. In order to estimate the deodorization in the toilet, the change in the odor degree of 10% ammonia water was measured for a long time with a portable solid odor sensor for ammonia odor in pumice of a porous solid impregnated with wood vinegar solution. Comparison with the control It was possible to remove the ammonia odor extremely effectively.

(Example 2) A sustained-release deodorant solid product using a wood vinegar solution of 0.
Deodorizing effect on 01% methyl mercaptan. Example 1
The sustained-release deodorant solid matter in which the wood vinegar solution was permeated and adsorbed was dried by heating at 30 to 35 degrees or freeze-dried in the same manner as in. In this example, the one dried by heating was used. In order to estimate the deodorizing effect, a portable type odor sensor for sulfur odor was used and the odor of a 0.01% methyl mercaptan solution was measured for several hours. As a result, the odor was extremely effectively removed by comparison with the control.

(Example 3) Deodorizing effect of rooibos tea on garlic odor. A sustained-release deodorant solid substance containing a rooibos tea extract as a deodorant component was prepared as follows. 6 g of rooibos tea leaves are put into about 500 ml of water and boiled for 15 minutes to obtain an orange-red solution. A weight of 100 g of a porous iron body was immersed in this, left to stand overnight, treated for 30 minutes in an ultrasonic bath, and then air dried. When 1 g of garlic was mashed with this deodorant solid substance and put in a 5 liter nylon bag, the deodorant effect was evaluated by 5 sensory examiners to determine the difference from the control, and it was extremely effective. It was found that the garlic odor was successfully removed.

(Example 4) Deodorizing effect of a controlled release deodorant solid substance using teatryl oil on food waste. Put 10 or more solid materials molded from fine hard paper in tea trill oil and
It was treated in an ultrasonic bath for 1 minute and air dried. This deodorant solid agent was added to 30g of garbage in a nylon bag of 5 liters, and 5 sensory testers judged the deodorant effect from the control, and it was very effective. I was able to remove the odor.

(Example 5) A wood vinegar solution was adsorbed on a porous ceramic and air-dried. When this deodorant solid substance was put in a simple toilet for small animals such as cats and used, the deodorant effect continued for more than one month.

(Example 6) When a wood vinegar solution was permeated into a porous material and attached to a seal or the like and fixed to the driver's seat as a deodorant in the automobile, the deodorant effect continued for more than one month.

(Example 7) As a sustained release deodorant solid substance, a pumice stone of the size of a tennis ball was made to adsorb wood vinegar, and one piece of this was placed in a Japanese-style toilet and used, and the deodorant effect was obtained for one month or more. Lasted.

(Example 8) When the present agent was used as an indoor deodorant by placing it in a plant or a plant model or a flower pot of artificial flowers, the deodorant effect continued for one month or more. The above eight examples have been given, but the present invention is not limited thereto, and the shape and the use are not limited thereto.
