An aqueous solution prepared by previously adding an aqueous liquid of the substance (C) having deodorant and / or aromatic properties to the water-thickening polymer (B) is mixed with the water-absorbent resin (A) to obtain a gel. An aqueous solution prepared by previously adding an aqueous liquid of the substance (C) having deodorant and / or aromatic properties to the water-absorbent resin (A) is mixed with the water-thickening polymer (B) to obtain a gel. (A), (B) and (C) are simultaneously mixed to obtain a gel.

That is, when the particle diameter is usually the same, there are many cases where the water absorption rate of the water-absorbent resin (A) is larger than the dissolution rate of the water-thickening polymer (B). When mixed with the aqueous liquid of the substance (C), the water-absorbent resin (A) absorbs most of the aqueous liquid of the substance (C) having deodorant and / or aromatic properties to form gel-like particles. The water-thickening polymer is gradually dissolved by a small amount of the aqueous liquid of the substance (C) having deodorant and / or fragrance held between the particle-like particles to form an aqueous solution. It has been found that the water-absorbing gel particles are bonded (coupled) to each other to enhance the deodorant and / or shape retention of the fragrance of the present invention. Furthermore, although the water-absorbent resin (A) absorbs the aqueous liquid of the substance (C) having deodorant and / or fragrance to form a water-insoluble gel, the water-thickening polymer (B) is less soluble. If the container is filled at a time when it is not performed, the liquid is low in viscosity, so that the container can be easily filled. In addition, it has been found that since the dissolution of the water-thickening polymer (B) gradually progresses in the container after filling, the gel-like deodorant and / or fragrance having good shape retention of the present invention is formed.

The molded body of the water-swellable resin of the present invention is fixed, and the container containing the water-absorbent resin and the water-thickening polymer is previously deodorized and / or deodorized.
Alternatively, add an aromatic liquid, absorb and swell the resin, cover and put it on the store. When actually used, the lid is removed and placed in a room, toilet, car, or the like to obtain a deodorizing and / or aroma effect, and the swollen and expanded molded article of the water-swellable resin is deodorized. It can be enjoyed to see how it gradually decreases due to the volatilization of the aromatic liquid. Replace the product when it is almost in the original condition before liquid absorption, or add a new deodorant and / or fragrance and use it again.

The deodorant and / or aromatic liquid is put into a container in which a molded article of the water-swellable resin containing the water-absorbent resin and the water-thickening polymer of the present invention is fixed, and placed in a room, a toilet, a car, or the like. The deodorant and / or fragrance effect can be obtained, and the water-swellable resin molded article can be enjoyed by gradually absorbing the deodorant and / or fragrance liquid, swelling and growing. In addition, it is enjoyable to see the water-swellable resin molded article which has swollen and becomes smaller due to deodorization and / or volatilization of the aromatic liquid (aqueous liquid). When the product is almost in its original condition, replace the product or add a new deodorant and / or fragrance and use it again.

-2 [rice extract, manufactured by Nippon Kasei Co., Ltd.] was diluted 30-fold with water to prepare a deodorant solution. This deodorant liquid (10
(00 ml), a mixture of the water-absorbing resin prepared in (1) and the water-thickening polymer was added to obtain a gel. The viscosity of the gel was 13.0 Pa _· s, and the transmittance was 92%.

Example 2 (1) The water-absorbing resin and the water-thickening polymer were mixed in the following mixing ratio. Sun Fresh ST-610 25 parts Alonbis SS 1 part Note) Sun Fresh ST-610: acrylic water-absorbent resin, average particle size 350-500 microns, water absorption performance 400
g / g, Sanyo Kasei Kogyo Co., Ltd. Aronbis SS: Purified sodium polyacrylate, manufactured by Nippon Pure Chemical Co., Ltd. (2) On the other hand, as a deodorant substance, Eporion N
Using -1000 [vegetable organic acid and organic acid salt, manufactured by Eporion Co., Ltd.], it was diluted 30 times with water to prepare a deodorant liquid. A mixture of the water-absorbing resin and the water-thickening polymer prepared in (1) was added to the deodorant solution (1000 ml) to obtain a gel. The viscosity of the gel was 16.0 Pa _· s, and the transmittance was 79%.

Example 3 (1) Deodorant and / or fragrance article (molded article of water-swellable resin);
The mixture was kneaded at 15 ° C. for 15 minutes and pressed into a mushroom-shaped mold with an expanded umbrella. The molded product was taken out to obtain a molded product of the water-swellable resin of the present invention having a mass of 3.8 g. Sunfresh ST-500MPS 53 parts Elastran ET1040 43 parts Phthalocyanine pigment 4 parts Note) Sunfresh ST-500MPS: acrylic water-absorbent resin, average particle size 20-50 microns, water absorption performance 40.
0 g / g, Sanyo Kasei Kogyo Co., Ltd. Elastran ET1040: Thermoplastic urethane resin, Takeda Birdish Urethane Kogyo Co., Ltd.

(2) The water-absorbing resin and the water-thickening polymer were mixed in the following mixing ratio. 6 parts Sunfresh ST-610 0.5 parts Aronbis SS Note) Sunfresh ST-610: acrylic water-absorbent resin, average particle size 350-500 microns, water absorption performance 400
g / g, Sanyo Kasei Kogyo Co., Ltd. Aronbis SS: purified sodium polyacrylate, manufactured by Nippon Junyaku Co., Ltd. (3) On the other hand, Apollite F as a deodorant substance
-2 [rice extract, manufactured by Nippon Kasei Co., Ltd.] was diluted 30-fold with water to prepare a deodorant solution. This deodorant liquid (65
(0 ml), a mixture of the water-swellable molded article prepared in (1) and (2), the water-absorbing resin and the water-thickening polymer was added. Four days after immersion, the molded article of the water-swellable resin swelled greatly in the transparent gel. The water-swellable resin molded product was taken out and weighed to be 152 g. The shape of the swollen water-swellable resin molded article was large without distortion and maintaining the shape before swelling. This was left indoors. The shape of the swollen water-swellable resin molded article gradually decreased with the water-absorbent resin while maintaining the initial shape due to volatilization of the deodorant liquid, and returned to almost the size before swelling after two months. .

The evaluation method is as follows. [Viscosity] The temperature of the gel was adjusted to 25 ° C, and a B-type viscometer (6r
pm). [Transmittance] A 10-mm-thick glass cell was filled with a gel substance whose temperature was controlled at 25 ° C., and the transmittance of visible light (700 nm) was measured.

[0048]

The deodorant and / or fragrance of the present invention has the following features. Since the deodorant and / or fragrance of the present invention has good shape retention,
When the container is moved or dropped, it is easy to handle without deformation or spillage. Since the deodorant and / or fragrance of the present invention has a transparent feeling,
Excellent aesthetics. When a deodorant and / or fragrance article containing a water-swellable molded article is used, the molded article of the water-swellable resin absorbs and releases water, so that the molded article gradually becomes larger or smaller while maintaining its shape. You can enjoy the state of going. From the above, the deodorant and / or fragrance of the present invention is useful as a deodorant and / or fragrance having excellent interior properties.
