Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to incense sticks such as mosquito coil sticks.

[0002]

BACKGROUND OF THE INVENTION Generally, incense sticks are combustion bases such as wood powder, foliage powder, etc., paste agents such as pepper powder, corn starch, etc., active ingredients such as fragrances and insecticides, etc., pigments, and antiseptic agents. Other components such as an agent are blended, an appropriate amount of water is added thereto and kneaded, and then molded into a predetermined shape, dried or punched and dried into a predetermined shape.

[0003]

In conventional incense sticks, for example, mosquito coil sticks, malachite green is used as a pigment to give a green appearance color. However, it is difficult to completely erase the inherent color of the combustion base such as wood powder, foliage powder, etc. Even if the combustion base is made into a fine powder, the appearance color is a bright green color of malachite green. It becomes a mosquito coil with an appearance color of dark brown instead of being, and even if it is tried to enhance the appearance color as an incense from the visual impression, the color of the appearance color is limited because of the use of the combustion base. The color inside the frame is unavoidable.

Further, as disclosed in Japanese Patent Publication No. 43-3919, an incense stick using carbon powder as a combustion base and a white pigment mainly composed of titanium white or titanium white as a pigment, and JP-A-48-77033. As disclosed in Japanese Patent Laid-Open Publication No. JP-A-2004-134, incense stick with a bright appearance has been proposed by mixing titanium yellow as a pigment.

However, since these incense sticks are only colored, the appearance color is not bright and bright, and the visual impression cannot be enhanced.

Therefore, an object of the present invention is to provide an incense stick capable of solving the above-mentioned problems.

[0007]

Means for Solving the Problems and Actions The inventors of the present invention have conducted extensive studies based on the above-mentioned object, and as a result, found that mixing aluminum hydroxide produces a bright incense with a bright appearance color. That is, the incense stick of the present invention is an incense stick made of a combustion base, a sizing agent, an active ingredient agent, a pigment, etc. and aluminum hydroxide, preferably an incense stick containing 2.5% by weight or more of aluminum hydroxide. This makes the incense stick color bright and clear.

As the incense stick of the present invention, wood powder 13.0% by weight, pyrethrum extracted lees powder 33.8% by weight, tea powder 13.0% by weight, camphor powder 20.0% by weight, aluminum hydroxide 20.0.
% By weight and 0.2% by weight of malachite green were prepared by a known kneading method. The hue of the appearance color of the incense stick thus created was 2.5 G, the lightness was 5 and the saturation was 6 (in accordance with the standard color chart JISZ8721), and the appearance color was vivid and bright. It is considered that the reason for this is that malachite green mixed as a pigment by aluminum hydroxide becomes even brighter and brighter.

[0009]

[Examples] Next, examples of the present invention will be described, but the invention is not limited to the examples. (Test Example 1) Wood powder, pyrethrum extracted lees powder, tea powder, pepper powder, α-
Starch, malachite green, and aluminum hydroxide were mixed according to the formulation shown in Table 1 below, and incense was prepared by a known kneading method. Regarding the appearance color of this incense stick, the hue, lightness, and saturation, which are the three attributes of the color, are standard color chart JISZ8721.
The results shown in Table 1 below were obtained. For comparison, as shown in Table 1 below, aluminum hydroxide was not mixed to prepare an incense stick by a known kneading method, and the appearance color of this incense stick was determined by the hue, lightness, and saturation as the three attributes of the color. In the same manner as described above, the result of examination by the standard color chart JIS Z8721 was obtained as shown in Table 1 below.

[0010]

[Table 1]

From these results, it was found that the brightness and the saturation were improved by mixing aluminum hydroxide.

13% by weight of wood flour, 20% by weight of camphor flour, 1 tea powder
3% by weight, malachite green 0.2% by weight, aluminum hydroxide X% by weight, and 100% by weight of pyrethrum-extracted meal powder were used to prepare incense by a known kneading method. With respect to this incense stick, the three attributes of color, hue, lightness, and saturation were examined by the standard color chart JISZ8721, and the results shown in Table 2 below were obtained.

[0013]

[Table 2]

As a result, 2.5% of aluminum hydroxide was added.
Addition improves the lightness, adding 5.0% to 20% further improves the lightness, adding 25.0% or more further improves the lightness, and adding 5.0% sharply improves the saturation. It turned out to be. For this reason, it is preferable to add 2.5% or more of aluminum hydroxide.

(Test Example 3) Incense was prepared by a known kneading method as shown in Table 3 using blue No. 1, yellow No. 202 and red No. 102 as dyes other than malachite green, and aluminum hydroxide was used for comparison. Table 3 without
The incense was prepared by a known kneading method with respect to the formulation shown in (1), and the appearance color of these incense was examined by the standard color chart JISZ8721 for the three attributes of color, hue, lightness, and saturation. It was

[0016]

[Table 3]

From this, it was found that although the lightness was improved by adding aluminum hydroxide to each dye, the saturation was not changed when Red No. 102 was used.

Test Example 4 Wood powder 20% by weight, Camellia powder 25% by weight, Tea powder 20% by weight, Red No. 104 as a pigment 0.9
%, Yellow No. 202 0.6% by weight, aluminum hydroxide X% by weight and pyrethrum-extracted meal powder to 100% by weight, and incense was prepared by a known kneading method. With respect to this incense stick, the three attributes of color, hue, lightness, and saturation were examined by the standard color chart JISZ8721, and the results shown in Table 4 below were obtained.

[0019]

[Table 4]

From this, it is possible to improve the lightness sequentially by adding aluminum hydroxide at 10% and 20%, and it is possible to change the hue by adding aluminum hydroxide. At that time, the appearance color is changed. It becomes bright and bright.

Test Example 5 With respect to the formulation No. 1 shown in Table 1 above, 0.3% pinamine forte was added to prepare an incense stick in the same manner as described above. The hue that is the three attributes of the color of this incense stick,
The lightness and the saturation were examined by the standard color chart JISZ8721. The effective volatilization rate of the insecticide was measured for this incense stick. As a result, regarding the hue, lightness, and saturation of the appearance color of the incense stick, the same effects as in Table 1 were obtained, and the appearance color became bright and bright. The effective volatilization rate of the insecticide is about 70% of the product of the present invention,
About 68% of the comparative product was obtained, and almost the same result was obtained without the influence of aluminum hydroxide.

(Test Example 6) For Formula No. 1 shown in Table 1 above, 1.0% floral mixed fragrance was added to prepare an incense stick in the same manner as described above. The three attributes of the color of this incense stick, hue, lightness, and saturation, were examined by the standard color chart JISZ8721. The sensory evaluation of the scent of this incense stick was conducted by five people. As a result, regarding the hue, brightness, and saturation of the incense,
The same effect as in Table 1 was obtained, and the appearance color was bright and bright. Further, when the sensory evaluation of the scent was compared with the odor stimulating property, the original scent of the fragrance, and the like, it was determined that the product of the present invention and the comparative product had the same effect.

[0023]

[Effects of the Invention] The appearance color of the incense stick becomes vivid and bright,
Moreover, the volatilization rate of the active ingredient and the performance are not reduced.
