Description

   The present invention relates to a volatile substance-carrying sheet for a blower type aroma. More specifically, the present invention relates to a volatile material-carrying sheet that gradually releases a fragrance that is volatile.

The blower-type aroma device is widely used for aromatherapy because of its low cost and easy maintenance. In this device, favorite essential oil (hereinafter abbreviated as fragrance)
Is dropped onto the volatile substance-carrying sheet, and the fragrance is forcibly volatilized by blowing air. Many kinds of fragrances are used.

   However, some fragrances have extremely fast volatility, and when these are used, there has been a problem that the volatile agents are completely volatilized in a short time.

In order to solve this problem, a method of remodeling the structure of an aroma device has been proposed (Patent Document 1). This prevents the wind generated by the blower from directly hitting the volatile support sheet and provides a cover having an air outflow hole so as to cover the support sheet support provided on the front surface of the blower. In this method, the fragrance is gradually released by causing air to stay in the space between the carrier sheet supporting portion and the cover by wind. However, even if this method is used, the improvement effect is not sufficient.

In addition, various methods using a retarder for controlling volatile substances have been proposed (Patent Documents 2 to 5). For example, in Patent Document 2, the volatility adjusting substance is a wax, but the wax itself is a carrier, and this is pretreated with a fragrance and molded. Therefore, a favorite fragrance cannot be selected and used depending on the day.

In Patent Document 3, the padding or impregnating substance is applied to the pad, but it is used for the initial volatilization adjustment of the aqueous base liquid medicine. Cannot be used.
JP 2003-159317 A

Furthermore, Patent Document 4 is a method for suppressing the volatilization rate based on the formation of a molecular complex between a surfactant and a fragrance, but it is a method that is used after crystallization, which is cumbersome to operate and is liable depending on the day. It is not possible to select and use a fragrance according to the condition.

As described above, there is no known method for releasing a fragrance having a high volatilization rate in a blower type fragrance that selects a fragrance according to preference according to the day.

The present invention has been made in view of the above, and it is an object of the present invention to provide a volatile substance-carrying sheet that releases a fragrance having a high volatilization rate in a blower-type fragrance that selects a fragrance according to preference according to the day. To do.

As a result of intensive studies to achieve the above object, the present inventor has found that a fragrance having a high volatilization rate can be gradually released by impregnating or applying a wax to a sheet, thereby completing the present invention. It came.
That is, the present invention provides a volatile substance-carrying sheet that releases a fragrance having a high volatilization rate, which is impregnated or coated with 5% or more of waxes based on the total weight of the sheet after impregnation or coating. It is.

   The present invention relates to a volatile substance-carrying sheet obtained by impregnating or applying 5% or more of waxes with respect to the total weight of the sheet after impregnation or application in a blower-type aroma device that selects a fragrance according to taste depending on the day. By using, there is an effect of releasing a fragrance having a high volatilization rate.

Hereinafter, the present invention will be described in detail.
The waxes used in the present invention are petroleum-based paraffin wax and microcrystalline wax, plant-based carnauba wax, candelilla wax and wood wax, animal-based bees wax and whale wax, and mineral-based montan wax. And synthetic polyethylene wax.

   The volatile substance-carrying sheet used in the present invention refers to a thick sheet having air permeability produced by a dry method or a wet method mainly using pulp. Pulp includes hardwood or softwood kraft pulp or sulfite pulp, which is wood pulp, and non-wood pulp. Synthetic fibers, chemical fibers, or natural fibers can be included as fibers other than pulp. Moreover, a papermaking auxiliary may be included. When the wax is impregnated with an aqueous system, it is necessary to give wet paper strength during sheet preparation. When producing by a wet method, a wet paper strength agent is usually added internally.

  In the present invention, in order to impregnate or apply the wax, a wax emulsion or solution may be used, or the wax may be melted and applied as it is. As the impregnation method, a dipping method, a size press method, a spray method, or the like can be used. As a coating method, a roll coating method, a blade coating method, a knife coating method, an air knife coating method, a wire bar coating method, or the like can be used.

In the present invention, when a sheet is impregnated with a wax emulsion, a small amount of surfactant may be used as a penetration enhancer when the permeation time is long.

In the present invention, the ratio of the waxes to be impregnated or applied should be 5% or more with respect to the total weight of the sheet after impregnation or application. If it is less than 5%, a sufficient sustained release effect cannot be obtained. The higher the impregnation rate, the higher the sustained release effect. What is necessary is just to set an impregnation rate in consideration of the target sustained release performance.

The present invention will be specifically described below with reference to examples.
Example 1 and Comparative Example 1

LBSP (sulfate) was disaggregated with a tapi disaggregator, and then a wet paper strength agent (AF-255 manufactured by Arakawa Chemical Industries) was added to pulp 0.5% to prepare a handsheet having a basis weight of 850 g / m2. This sheet was impregnated with a paraffin wax emulsion (SPW-116H manufactured by Arakawa Chemical Industries) to obtain a sheet having an impregnation ratio of 30%. Using the paraffin wax emulsion impregnated sheet and the non-impregnated sheet as a volatile substance-carrying sheet, about 0.2 g of the fragrance eucalyptus (GAIA essential oil) was dropped on a blower-type aromatizer (Aroma Breeze Friends manufactured by Alta Corporation), Blowing started. The results of Table 1 were obtained by tracking the volatilization rate of the fragrance by weight reduction. When the paraffin wax emulsion non-impregnated sheet was used, about 70% of the fragrance was volatilized in 20 minutes. However, when the paraffin wax emulsion-impregnated sheet was used, it took 3 hours for 70% to volatilize. Sufficient sustained release effect was shown.

実施例２及び比較例２

Example 2 and Comparative Example 2

The results of Table 2 were obtained in the same manner as in Example 1 and Comparative Example 1 except that the impregnation ratio of the paraffin wax emulsion was 12% and the fragrance was orange sweet (essential oil manufactured by GAIA). When the paraffin wax emulsion non-impregnated sheet was used, about 80% of the fragrance was volatilized in 20 minutes, but when the paraffin wax emulsion-impregnated sheet was used, about 2.5 hours until 80% was volatilized. Therefore, it showed a sufficient sustained release effect.

実施例３及び比較例３

Example 3 and Comparative Example 3

Ventilation aromatizer (Aroma Breeze Ecomini manufactured by Alta Corporation) and a sheet provided with 50% paraffin wax emulsion impregnated in this, about 0.15 g of fragrance lemon (GAIA essential oil) was dropped and volatilized. The rate was followed and the results in Table 3 were obtained. When the installed sheet was used as it was, about 60% of the fragrance was volatilized in 20 minutes. However, when the paraffin wax emulsion impregnated sheet was used, it took about 4 hours to evaporate, Showed a sustained release effect.

実施例４及び比較例４

Example 4 and Comparative Example 4

   As a volatile substance-carrying sheet, a dry pulp nonwoven fabric (TDS pigeon sheet manufactured by Oji Kinocross Co., Ltd.) having a basis weight of 1 kg / m 2 was impregnated with carnauba wax emulsion (EMUSTAR-0413 manufactured by Nippon Seiki) to obtain a sheet having an impregnation rate of 40%. Except for using this impregnated sheet and non-impregnated sheet as the volatile substance-carrying sheet, the volatilization rate was measured and tracked using the methods of Example 1 and Comparative Example 1, and the results shown in Table 4 were obtained. When the carnauba wax emulsion non-impregnated sheet was used, the fragrance was slightly over 50% in 20 minutes and over 90% in 40 minutes, but over 90% when the carnauba wax emulsion-impregnated sheet was used. It took 4 hours to volatilize and showed a sufficient sustained release effect.

実施例５及び比較例５

Example 5 and Comparative Example 5

The handsheet prepared in Example 1 was impregnated with a microcrystalline wax emulsion (EMUSTAR-042X manufactured by Nippon Seiki) to obtain a sheet with an impregnation rate of 30%. Using this sheet and an unimpregnated sheet to a blower-type aromatizer (Aroma Breeze Ecomini manufactured by Alta Corporation), about 0.15 g of a fragrance sweet orange (GAIA essential oil) was dropped and the volatilization rate was traced. The result was obtained. When the unimpregnated sheet was used, 90% of the fragrance was volatilized in 20 minutes, but when the microcrystalline wax emulsion impregnated sheet was used, it took about 6 hours to evaporate. Showed a sustained release effect.

As described above, since a sheet impregnated or coated with 5% or more of the wax of the present invention can release a fragrance that tends to volatilize, the fragrance can be selected according to taste depending on the day. When using a blower-type aroma, it can be used as a volatile substance-supporting sheet for a fragrance that is easy to volatilize.
