Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to volatile compositions.

In more detail, it relates to a volatile composition that changes color as the volatile drug supported on the rt inhalation carrier evaporates.0 (Prior art) Conventionally, deodorants, insecticides, etc. It is widely practiced to prepare a volatile composition by supporting a volatile drug or a liquid fragrance Pl-. However, since the adsorption carrier itself of these volatile compositions does not reduce the droplet accumulation over time, unlike gel-like fragrances, it is difficult to judge the end point of the effect based on appearance. It's difficult 901 几,t
For example, when a liquid incense Pl- is inhaled, the end point of whether or not it is effective is determined by the sense of smell, even if the drug to be inhaled has a scent or odor, as seen in the case of volatile compositions. 90 (Objective of the present invention) The present invention was made in view of the above-mentioned current situation, and its purpose is to reduce the effect of the carried volatile drug by volatilization and its effect at the point when it is removed. , 17t is a volatile composition that loses its effectiveness and changes color after nine months, and the time to replace it is visually determined by 11A.
The purpose is to make it possible to judge iK. The present invention was originally filed by the present inventor and is based on a detoxifying composition (for example, Japanese Patent Application No. 55-185643 and Japanese Patent Application No. 56-54804).

(Japanese Patent Application No. 58-68211, etc.), the purpose is to clarify the end point of the effect and to provide a deodorizing composition that is convenient to use.

(Characteristics and Structure of the Present Invention) The feature of the present invention is that the active ingredient of the supported volatile drug evaporates and its effect fades, and the matrix adsorbs the coloring agent, which loses its effect and changes color at time t. They coexist in the carrier and are at point t.

The structure and detailed contents of the volatile composition of the present invention will be described below.

Inorganic carriers capable of supporting liquids such as reeds, synthetic lucium silicate, activated alumina, natural materials, synthetic zeolites, and diatomaceous earth can be used as adsorption carriers for supporting volatile drugs used in the invention. There are no particular restrictions on the ingredients, particle size, etc.

In addition, synthetic organic compounds, such as cellulose derivatives such as crystalline cellulose, hydroxypropyl methylcellulose, or superabsorbent resins, which have a high ability to support liquids, are also useful as adsorption carriers for the composition of the present invention. It is.

Incidentally, in the volatile composition of the present invention, there are no particular restrictions on the coloring agent that causes color change to coexist in the adsorption carrier, as long as it has the function of changing color as the adsorbed material evaporates. Most commonly, various pH indicators are used to utilize the change in pH in the adsorption carrier that occurs as the volatile drug evaporates, and colorants such as sulfuric acid, which change color depending on the presence or absence of water in the carrier, are used. Inorganic compounds such as copper and cobalt chloride that change color depending on the presence of water of crystallization; Examples include coloring agents that develop color. Which of these colorants to use should be selected individually depending on the type of volatile agent used, taking into consideration the degree of discoloration, etc. For example, deodorizing liquids such as stabilized chlorine dioxide solution, wood vinegar solution, or deodorizing liquid extracted from plants, pesticides, insect repellents, and volatile rust preventives are especially effective when they evaporate. There is no such limit. The ratio of the amounts of these volatile chemicals to the above-mentioned discoloring coloring agent depends on the type of adsorption carrier used, the desired degree of discoloration, etc., but in general, it is 0.01 to 5 of the coloring agent that changes color when
Amounts in % by weight are preferably used.

In order to prepare the volatile composition of the present invention, a colorant that changes color is adsorbed on an adsorption carrier in advance, and then a volatile agent such as a deodorizing liquid is adsorbed, or a colorant that changes color is added to the volatile agent. Either method may be adopted, including adsorption on the entire liquid solution and dispersed adsorption carrier.

Furthermore, when molding the adsorption carrier by a wet method or the like, the coloring agent may be completely mixed in the slurry of the material and molded.

The volatile composition of the present invention can be used in various adsorbents in which a volatile drug is adsorbed onto an adsorption carrier.

It has great significance as a product that improves the drawback that it was difficult to determine the end point of its effectiveness, and it has a wide range of applications in fields such as deodorants, insect repellents, and agricultural chemicals, and its effects are not seen in conventional products. It is elaborate.

Examples will be shown below, but the invention can be implemented in various forms within the scope of the technical idea of the present application, regardless of the examples. % and Tokyo Metropolitan Government in weight % and weight parts, respectively.

Example: The present inventor previously filed an application for an extinguishing composition (Japanese Patent Application No. 55-13).
No. 5643], the following color-changing volatile composition was prepared according to the present application.

2 1. 0.5% cresol red (e2tf/ls ('rst, manufactured by Wako Pure Chemical Industries, Ltd.) was dissolved in 100 parts of commercially available spherical activated alumina (2 to 3% f, manufactured by Sumitomo Aluminum Co., Ltd.). When 50 parts of stabilized chlorine dioxide solution of 0.000 ppm at 8 degrees Celsius was inhaled, it exhibited a reddish-purple color of maroon color.The volatile composition of the present invention (0.00
01028 degrees is 7.0001) 1) 6 meters. Place this in a 2oomz plastic container with an open top.
When I put it in a 21at refrigerator and measured the color change and cLo2 degree over time, the results were all the same.
The g concentration was measured by a conventional iodometric titration method. ◇ It has become clear that the volatile composition of the present invention changes color. Example 2 Commercially available spherical calcium silicate (2 to 3% f).

Prepare Fluorite manufactured by Tokuyama Soda Co., Ltd.
0.01% bromophenol blue (('19 Htc 8rq OgtS-) was dissolved in a commercially available wood vinegar solution (Seiko Sangyo Co., Ltd., trade name: Neo Shoeless), and 9 m4 of the rinsing solution IQ was added to 100 parts of the above adsorption carrier. A volatile composition of the present invention was obtained by inhaling the volatile composition of the present invention.The thus obtained composition of the present invention exhibits a yellow color.
It has the property of turning purple, and eventually takes on a grayish-purple appearance.

Example 8 Volatile composition previously filed by the present inventor (Japanese Patent Application No. 58-6)
In Example 1 of No. 8211), 15 parts of copper sulfate pentahydrate (0uSO4-5H20) was mixed into the slurry liquid as a coloring agent that changed color.After solidification, the volatile composition exhibited a pale blue color. The color gradually faded as the cLO2 gas and water evaporated, and the color disappeared after 35 days.0 (or more)
