Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel fragrance material, particularly a scented fragrance material suitable for use in adult disposable diapers.

Traditionally, cloth diapers have been used for infants and young children, but in recent years, disposable disposable diapers have been developed, marketed, and widely used.

At the same time, paper diapers are also used by adults who are unable to urinate, such as the so-called bedridden elderly. Not only general households with such adults, but also nursing facilities that accommodate large numbers of adults have to care for large numbers of them with limited staff, and some adults are very heavy, making it difficult to change disposable diapers in a timely manner. Hard to do.

Therefore, the adults who use the urination have to endure the unpleasant odor and moisture during and after urination, and the current situation is that nursing staff are also bothered by the odors when changing the urination.

Accordingly, it is an object of the present invention to provide a material that can be used in conjunction with disposable diapers to eliminate discomfort caused by odor or moisture associated with urination.

Thus, the present invention provides an aromatic material for disposable diapers made by blending a fragrance with one or more of hygroscopic materials such as silica gel, zeolite, kaolin, and talc, or one or more of these hygroscopic materials and a water-absorbing material. The present invention provides an aromatic material for disposable diapers made by blending a fragrance with a polymer.

To explain the present invention in detail, in the present invention, a fragrance is blended with one or more of hygroscopic inorganic clay materials consisting of silica gel, zeolite, kaolin, and talc. Among the hygroscopic substances mentioned above, silica gel is preferred, especially
It is preferable to use particles with a particle size of 40 mesh or less. As the fragrance, various blended fragrances such as rose-based fragrances can be used. It is preferable to use the fragrance in an amount of 0.5 to 5 parts by weight per 100 parts by weight of the hygroscopic substance such as silica gel.

When the aromatic material obtained in this way is adsorbed on silica gel etc., the fragrance usually disappears, but when it comes into contact with moisture, the fragrance that had disappeared will be generated and radiated to the surrounding area. Become.

Therefore, when this is used in a disposable diaper, upon contact with urine excreted by the user, the fragrance from the fragrance contained therein is emitted, thereby masking the odor. In this way, you will not be able to feel any bad odor, and only the aroma will be felt. In addition, urine is also absorbed therein, and therefore, the discomfort caused by the odor or moisture that accompanies urination during use can be eliminated.

According to another example of the present invention, when a water-absorbing polymer is further used in addition to the hygroscopic material such as silica gel and a fragrance is blended with these, the water at the time of use is absorbed by the water-absorbing polymer together with the hygroscopic material. It is also possible to eliminate discomfort caused by humidity. Of course, the fragrance is also retained and when used, this is released and the odor can be hidden.

Here, as the water-absorbing polymer, a water-absorbing acrylic polymer such as Arasorb 800 (trade name, manufactured by Arakawa Kagaku KK) can be used. It can absorb 800 times the amount of water. In this case, it is preferable to use 100 to 200 parts by weight of a water-absorbing polymer and 0.5 to 5 parts by weight of a fragrance per 100 parts by weight of a hygroscopic substance such as silica gel.

In the present invention, as described above, a hygroscopic inorganic clay material, a fragrance, or a water-absorbing polymer are used, but in addition to these, suitable reagents such as deodorants such as cyclodextrin can also be contained.

In either case, the fragrance contained is absorbed by hygroscopic substances and the fragrance disappears, but when it comes into contact with moisture, i.e. urine, a fragrance is generated and emitted, hiding the odor, and eventually the fragrance becomes a deodorizer or It acts as a deodorant and relieves discomfort.

When the aromatic material of the present invention is used in disposable diapers, it is preferable to arrange the aromatic material between the tissue and pulp layers on both the upper and lower surfaces of the diaper.

The following aromatic material of the present invention was prepared and used in adult disposable diapers, and the discomfort felt during urination was investigated.

1. Fragrance material 1 of the present invention was prepared by adsorbing 1 part by weight of a fragrance made of a rose-based blend product (trade name: Rose 97208, commercially available from Eikodo) to 100 parts by weight of silica gel of 40 mesh or less.

2. Adsorb 1 part by weight of the same fragrance as above, which is a rose-based blend, into 100 parts by weight of silica gel having a size of 40 mesh or less, and add it to a water-absorbing acrylic polymer (trade name: Arasorb, commercially available from Arakawa Chemical Co., Ltd.).
Aromatic material 2 of the present invention was prepared by blending 200 parts by weight of 800).

In either case, no aroma was released, but when water was added, aroma was observed to be released.

As a result of using the above aromatic material 2 in Pigeon KK disposable diapers on 12 men and women ranging in age from 55 to 92 years old,
10 people said that their discomfort had been resolved, and 2 people did not know.

As described above, it is clear that the aromatic material of the present invention is effective when used in adult disposable diapers, but it can of course also be effectively used in infant disposable diapers.
