JP4572206B2 - Application method of toilet paper and fragrance composition on toilet paper - Google Patents

Description

  The present invention relates to a porous starch, a fragrance composition, a coated paper product, and a fragrance composition coating method, and more particularly to a fragrance release control technique in which a highly volatile fragrance component is soaked into pores of a porous body. Is.

For example, a paper product such as a toilet roll is known in which a fragrance is applied to a roll sheet or the like so as to smell the scent that has been volatilized during use (see, for example, Patent Document 1).
JP 2004-49724 A

However, although the fragrance component is volatilized over time, the highly volatile fragrance component is volatilized in a short period of time. There was a problem that the fragrance could not be maintained, and the product value was not sufficient.
Then, the main subject of this invention is providing the porous starch which delays the discharge | release rate of a highly volatile fragrance | flavor component, a fragrance composition, the paper product with which this was apply | coated, and the fragrance composition coating method.

The present invention that has solved the above problems is as follows.
<Invention of Claim 1>
Porous starch having an oil absorption of 0.8 to 1.1 ml / g produced by decomposing starch or starch derivatives with an enzyme or acid and drying the decomposed product into powder, and adding at least 3 of top note, middle note and bottom note Toilet paper, wherein one of the two volatile components infiltrated with the top note and one not infiltrated with the porous starch including the middle note and the bottom note are applied to the paper tube .

(Function and effect)
Since the size of the plurality of holes (dents) formed on the surface of the porous starch is small and the area in contact with the outside air in this hole is small, the perfume permeates into this hole due to capillary action. It has become. Here, the starch that has been made porous has a larger surface area than the starch that has not been made porous, so that more perfume can permeate. In addition, since the fragrance is contained in the hollow of the hole, the area that comes into contact with the outside air is small, so the release rate of the fragrance is delayed compared to the case where highly volatile fragrance is sprayed on the entire starch surface. And the scent sustaining effect is improved.
Three volatile components can be obtained by infiltrating at least the top note with high volatility into the porous starch and applying the remaining components, which are low volatility components, without infiltrating into the porous starch as before. The uniform scent can be maintained without changing from the beginning to the end.

<Invention of Claim 2>
A method of applying a fragrance composition comprising at least three volatile components of a top note, a middle note, and a bottom note to toilet paper,
The components of the top note are pre-penetrated into porous starch having an oil absorption of 0.8 to 1.1 ml / g, which is produced by decomposing starch or starch derivatives with enzymes or acids , and drying the decomposed product into a powder.
Next, the remaining components are sprayed onto the application target portion of the paper tube of toilet paper ,
Next, the porous starch infiltrated with the components of the top note is sprayed on the application target part different from the sprayed remaining component, or mixed and sprayed on the same application target part as the sprayed remaining component. A method of applying a characteristic fragrance composition to toilet paper .

  According to the present invention, there is an advantage that the release rate of a highly volatile perfume component can be delayed.

Embodiments of the present invention will be described below.
<Porous starch>
As the porous body according to the present invention, it is preferable to use porous starch because it is inexpensive and has little influence on the human body. The particle diameter of the porous starch 1 is 1 to 100 μm, and a plurality of pores (dents) are randomly formed on the surface of the sphere. Therefore, the density is higher than that of starch of the same volume that is not made porous. The ratio is 0.1 to 0.9 (the non-porous starch is 1).
As shown in FIGS. 1 and 2, the porous starch 1 has a small size (hole diameter) of a plurality of holes (dents) formed on the surface of the sphere, and the area in contact with the outside air in the holes is small. It has become. And the fragrance | flavor 2 osmose | permeates into this hole by capillary phenomenon. Here, the starch that has been made porous has a larger surface area than the starch that has not been made porous, so that more perfume can permeate. Moreover, since the fragrance | flavor 2 has entered into the hollow of the hole, the area where it comes into contact with the outside air is small. Will be delayed and the scent sustaining effect will be improved.
Examples of the method for producing the porous starch 1 include potato starch, corn starch, sweet potato starch, tapioca starch, sago starch, rice starch, amaranthus starch and other natural starches, and their starch derivatives such as etherification, esterification and crosslinking. A method in which a solution obtained by decomposing one or more of them with an enzyme or an acid is dried with a drum dryer to form a powder.
Taking corn starch starch as an example, the density before decomposition is about 0.5 to 0.6 g / ml, and the density after decomposition is about 0.4 to 0.6 g / ml. The oil absorption capacity before decomposition is 0.4 to 0.5 ml / g, and the oil absorption amount after decomposition is 0.8 to 1.1 ml / g. Various things can be included inside the porous material (according to the JIS pigment oil adsorption test method), and there is an advantage that stability and sustained release can be imparted by including an unstable substance.
Although it does not specifically limit as the fragrance | flavor 2 which concerns on this invention, For example, a Ryuzen fragrance | flavor, a benzoin incense, a sea bream incense, a ghost cat incense, a clove oil, a galvanum, a jasmine absolute, a labutanam, a mate tea, merilot, mimosa, musk Natural fragrances such as Tonkin, Myrrh, Oak Moss or Moss de Chine, Milk Incense, Juniper Incense, Oris, Bachuri, Rosemary Oil, Sandalwood Oil, Vetiver Oil, Violet Leaf Absolute, Higher Alcohol, Aldehyde, Benzaldehyde, Benzoic Acid, Cinnamic Acid, Examples include aldehydes, cinnamon alcohol, coumarin, esters, indoles, ketones, salicylic acid and related compounds, various synthetic fragrances such as terpenoids and vanillin, or mixtures of two or more thereof. Commercial products can also be used.
By impregnating the pores of the porous starch 1 with a highly volatile perfume component, the volatilization can be delayed and sustained without changing the fragrance.

<Application of porous starch to aroma composition>
The fragrance composition composed of various fragrances mainly consists of three volatile components (top note, middle note, and bottom note). Over time, the top component is the most volatile. Therefore, it volatilizes quickly. Then, since the component ratio of the scent changes, the scent becomes different from the original one. Therefore, by allowing at least the most volatile top note to permeate into the pores of the porous starch, the release rate of the top note can be moderated, and the same scent can be maintained without significantly changing the volatile component ratio. Will be able to. Uniformity of the three volatile components by at least penetrating the highly volatile top note into the porous starch and applying other components that are less volatile components into the porous starch as before. A fragrance can be maintained without changing from the beginning to the end.
Here, the manufacturing method (fragrance composition) of the toilet roll at the time of using the porous starch 1 which made the paper tube part 10 used as the axial center of a toilet roll (not shown) permeate | transmit the top note of a fragrance composition at least The application method will be described with reference to FIGS.
First, although not shown in the drawing, the highly volatile top note component of the fragrance composition is at least preliminarily absorbed (permeated) into the porous starch. Next, as shown in FIG. 3, the remaining components are sprayed onto the paper tube unit 10. The spraying method at this time may be a known spraying method.
Next, as shown in FIG. 4, the porous starch 1 on which at least the top component is adsorbed is sprayed on the remaining sprayed component by a known spraying method such as spraying or roll transfer (the same as the sprayed remaining component). It is sufficient to mix them at the application target part). Thereby, volatilization of at least the top component can be suppressed and the scent can be maintained without being changed. Further, in place of mixing the porous starch 1 having at least the top component adsorbed in the same application target part as the remaining sprayed component, although not shown, it is applied to a different application target part from the sprayed remaining component. It may be sprayed. Furthermore, although not shown in the figure, the remaining components may be sprayed after the porous starch 1 on which at least the top component has been adsorbed is sprayed on the application target portion.
Note that the present invention is not limited to the paper tube section of the toilet roll, but may be applied to various types of paper products such as cartons, films, and sanitary thin paper.

Below, the toilet roll preservation | save test (acceleration test) was done about Examples 1-5 and Comparative Examples 6-9.
As a test condition, the highly volatile top note component of the fragrance composition is at least preliminarily absorbed (penetrated) into the porous starch. Next, as shown in FIG. 3, the remaining components are sprayed onto the paper tube unit 10. The spraying method at this time may be a known spraying method.
Next, as shown in FIG. 4, the porous starch 1 on which at least the top component is adsorbed is sprayed on the remaining sprayed component by a known spraying method such as spraying or roll transfer (the same as the sprayed remaining component). It is sufficient to mix them at the application target part). Thereby, volatilization of at least the top component can be suppressed and the scent can be maintained without being changed. Further, in place of mixing the porous starch 1 having at least the top component adsorbed in the same application target part as the remaining sprayed component, although not shown, it is applied to a different application target part from the sprayed remaining component. It may be sprayed. Furthermore, although not shown in the figure, the remaining components may be sprayed after the porous starch 1 on which at least the top component has been adsorbed is sprayed on the application target portion. The porous starch 1 used was “Lonfood OWP” manufactured by Nippon Star Chemical Co., Ltd., produced from corn starch starch.
Put the toilet roll manufactured by the above method into a sealable bag. This is installed under the condition of a constant temperature of 50 ° C.
