DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a composition of solid fuel that maintains the ability to prevent accidental ingestion.

[Prior Art] Conventionally, for example, solid fuel consisting of alcohol as a fuel component and fatty acid soda as a base material component has been used not only outdoors but also indoors as a heat source for keeping hot pots warm.
It is often used for tabletop use.

[Problems to be Solved by the Invention] Many of these solid fuel products are housed in naked bodies in cans, or are surrounded by a resin film, or even equipped with aluminum seedling holders. It may also be sold.

However, the solid fuel itself has a jelly-like appearance similar to that of food, and when used for household purposes, there is a high risk of accidental ingestion.

In addition, methanol is usually used as the combustion component of this solid fuel, and acute poisoning symptoms such as dizziness, feeling of weakness, headache, vomiting, and blurred vision appear at 8 to 30 methanol, and the lethal dose is 30 to 30 methanol. Considering that it is ~100-, it can be said that the risk of accidental ingestion as described above is extremely high.

Therefore, in order to prevent accidental ingestion, the present invention has a taste that makes people spit it out due to its bitter taste even if it is contained in 10,000 mouthfuls without being eaten or eaten, as well as having low toxicity and The aim was to provide a solid fuel that retains its original combustion characteristics.

[Means for Solving the Problems] In order to achieve the above object, the present invention has the following configuration for a solid fuel having accidental ingestion prevention performance.

That is, in a solid fuel consisting of alcohol as a combustion component and fatty acid soda, dibennylidene-D-sorbitol, or carboxyvinyl polymer as a base component, denatonium benzoate, burulin, 8-acetylated sucrose, or Oriental japonica extract is added to give a bitter taste. It is characterized by being contained as a substance.

In this solid fuel, examples of alcohols as combustion components include methanol, ethanol, and isopropanol, and examples of fatty acids as base components include stearic acid, palmitic acid, etc. Can be applied singly or in composite form.

Further, in the present invention, denatonium benzoate as a bitter substance has a melting point of 160 to 161°C, and its chemical structural formula is as follows.

There is no particular limitation on the amount of denatonium benzoate, but the preferred amount is o, o,
ooi% by weight or more. Moreover, this substance has an oral toxicity of L D 5o = 820 for rats, which is a level of toxicity that does not pose a problem considering the blending ratio.

Moreover, brulin has a melting point of 178° C. and its chemical structural formula is as follows.

There is no particular restriction on the amount of burulin to be added, but the preferred amount is 0.01% by weight or more from the viewpoint of bitterness evaluation characteristics. The toxicity is LD50=8 (intravenous injection in dogs), but oral toxicity does not pose a problem due to the amount used.

In addition, 8-acetylated sucrose has a melting point of 80 to 84°C,
Its chemical structural formula is as follows.

H3CO0 There is no particular limit to the amount of this 8-acetylated sucrose, but
Its preferred amount is 0.1% by weight or more in view of its bitter taste properties. Also, oral toxicity is low and does not pose a problem.

Moreover, the Jasperia japonica extract can be obtained by extracting the entire plant of the Jasmine japonica in the flowering stage into powder, that is, 1 part of the Jasmine japonica powder with 100 parts of methanol.

[Function] The solid fuel according to the present invention has a bitter taste that makes people with normal taste want to spit it out immediately when they take it into their mouth. Does not cause any change in appearance,
In addition, there are no adverse effects such as generation of strange odors. Furthermore, since the amount of bitter substance blended is extremely small, its toxicity is also extremely low.

The effects of the present invention are confirmed by the results of the following examples.

[Example] Next, the present invention will be explained in detail.

That is, methanol and fatty acid (stearic acid 80%) and bitter substances such as denatonium benzoate, brulin, 8-acetylated sucrose, or Oriental japonica extract are mixed and stirred in predetermined amounts to achieve the appropriate blending ratio. It was heated to about 65°C to dissolve it. Then,
Methanol in the appropriate mixing ratio was slowly added as an aqueous solution with stirring. Thereafter, it was cooled and solidified at 5° C. and formed into a predetermined shape (a columnar body with a cross-sectional diameter of 4C11 and a length of 2 cm, the same applies hereinafter) to obtain a solid fuel.

In addition, regarding the solid fuel having the performance of preventing accidental ingestion, which is based on dibenzylidene-D-sorbitol, the solid fuel according to the compounding ratio shown in each of the formulations 111 [L16 to Na25 in Table 2 below] was prepared by the following manufacturing method. Obtained.

In other words, alcohol and denatonium benzoate, brulin, 8-acetylated sucrose, or Oriental japonica extract as bitter substances are mixed in the appropriate proportions, and this is mixed with about 65%
A predetermined amount of dibenzylidene-〇-sorbitol was heated at ℃ and mixed with stirring to dissolve it, and then slowly added with stirring, and then cooled and assimilated at about 5℃ to obtain a solid fuel in a predetermined shape. Ta.

In addition, regarding the solid fuel that is based on carboxyvinyl polymer and has the ability to prevent accidental ingestion, the following Table 3 shows the formulation N [L
31 to N[L40 were obtained according to the blending ratios shown in each of them by the following manufacturing method.

In other words, half of the predetermined amount of alcohol, bitter substance and carboxyvinyl polymer (trade name: Hibiswako-104)
, manufactured by Wako Pure Chemical Industries, Ltd.) at room temperature to dissolve and disperse the remaining alcohol and a predetermined amount of organic amine (e.g., triethylamine, diisopropanolamine, or di(2- ethylhexyl〉amine, etc.)
A pre-dissolved substance was added while stirring slowly to form a gel, and then it was filled into a specified container and solidified to obtain a solid fuel in a specified shape6.The formulation in Table 1 was No. 11 to NI'1.15, formulation N [126 to N (L30) in Table 2 and formulation ratio 41 to NIL45 in Table 3 as a comparative example. It was obtained by blending the known substances naringin, caffeine, dimethylformamide or formaldehyde under the same conditions as above.

It should be noted that no change in appearance was observed in any of the solid fuels obtained in this way compared to those to which no bitter substance was added.

Next, 1 g of each solid fuel fragment obtained in this way
A panel of five adult males (25 to 30 years old) each took the sample in their mouths and evaluated its bitterness. The results of this evaluation are shown in Table 4 below for solid fuels corresponding to Table 1, Table 5 below for solid fuels corresponding to Table 2, and Table 3 below for solid fuels corresponding to Table 2.
