- a polyacrylate cross-linked product was used as the water absorbent resin.
- mugwort oil Examples 1 to 3 and 7
- ginger oil Example 4
- floral fragrance Example 5
- citrus fragrance Example 6 are used as fragrances, respectively. Ashes were used.
- “Others” shown in Table 1 includes water retention agents, hydrogen generation inhibitors, and the like.
- disposable warmer raw materials corresponding to each example were prepared. Then, the raw material was enclosed in a storage bag made of a non-woven fabric having an air permeability of 20000 sec / 100 mL to produce disposable warmers of Examples 1-7.
- Comparative Examples 1 to 8 the same raw materials as in the Examples were used (however, the mixing ratio of activated carbon and raw ash in each Comparative Example was different).
- the raw material of the disposable body warmer according to the comparative example was prepared. Then, the raw material was sealed in the same storage bag as in the example, and the disposable warmers of Comparative Examples 1 to 8 were produced.
- (A) Measurement of iodine adsorption capacity The iodine adsorption capacity of the disposable body warmer was evaluated by a method based on JIS K1474. Specifically, the following procedures [1] to [6] were performed. [1] A sample was weighed so that the residual concentration range after iodine adsorption included 2.5 g / L, and the sample was pulverized until it became uniform. [2] The pulverized sample was transferred to 100 mL of a flask with a brown stopper, and 50 mL of 0.05 mol / L iodine solution was added thereto and sealed.
- the sample was shaken at 210 times / min for about 15 minutes using a shaker to adsorb iodine to the sample.
- the solid content of the sample after shaking was separated with a centrifuge.
- 10 mL of the supernatant of the sample after centrifugation was weighed and titrated with a 0.1 mol / L sodium thiosulfate solution.
- 1 mL of a 1% by weight starch solution was added as an indicator when the iodine yellow color became lighter, and the titration was continued. When the blue color disappeared, the titration was terminated. From the titration amount by the above operation, the iodine adsorption amount (mg / g) per 1 g of the sample was calculated.
- ⁇ The maximum temperature is 45 to 60 ° C., and the heat generation duration of 40 ° C. or more is 5 hours or more.
- delta The maximum temperature is more than 40 degreeC and less than 45 degreeC, and the exothermic duration of 40 degreeC or more is less than 5 hours.
- X The maximum temperature is 40 ° C. or lower.
- the disposable warmers of Examples 1 to 7 had an iodine adsorption ability in an appropriate range, and were excellent products that achieved both an aroma effect and temperature performance.
- the disposable warmers of Comparative Examples 1 to 8 could not achieve both the fragrance effect and the temperature performance.
- the disposable warmers of Comparative Examples 1 to 3 and 5 to 7 have a good fragrance effect, but have a lower iodine performance than that of the present invention, so that sufficient heat generation cannot be obtained and the temperature performance is inferior.
- the disposable warmers of Comparative Examples 3 and 6 had an iodine adsorption ability as low as 250 to 260 mg / g, and the temperature performance was evaluated as “x”.
- the disposable warmers of Comparative Examples 4 and 8 had a high iodine adsorption ability and a high temperature performance of “ ⁇ ”, but the aroma effect was an evaluation of “x”. This is considered to be due to the fact that the fragrance is excessively adsorbed on the activated carbon and the fragrance effect of the fragrance is not exhibited because the iodine adsorption capacity is too high.
- the disposable body warmer of the present invention has an excellent balance between the effect of suppressing the adsorption of fragrance to activated carbon and the oxidative exothermic reaction of oxygen and iron powder adsorbed by activated carbon. As a result, while suppressing the unpleasant odor derived from the iron powder, the fragrance effect by the fragrance can be exhibited and the stable heat generation can be maintained.
- the disposable body warmer of the present invention can be used in both household and business fields.

本発明の使い捨てカイロは、鉄粉、活性炭、塩類、吸水性樹脂、及び水を含む発熱組成物を主原料とするものである。発熱組成物の組成を調整することによって、カイロが発熱するまでの時間や、発熱時の最高温度、及び発熱の持続時間等をコントロールすることができる。以下、発熱組成物の各組成について詳細に説明する。
本発明の使い捨てカイロは、温感効果に加えて、芳香効果やリラックス効果を奏するように、香料が付与される。香料を例示すると、ガラクソリド、ムスクケトン、ヘキシルシンナミックアルデヒド、エチレンブラシレート、メチルアトラレート、ヘキシルサリシレート、オレンジャークリスタル、テルピネオール、シトロネロール、ゲラニオール、ネロール、リナロール、ジヒドロリナロール、テトラヒドロリナロール、ジヒドロミルセノール、メントール、ボルネオール、イソボルネオール、シトロネラール、シトラール、ジメチルオクタナール、カルボン、ジヒドロカルボン、プレゴン、メントン、トリシクロデセニルアセテート、アンブロキサン、キャシュメラン、カロン、ヘリオトロピン、インドールアロマ、インドール、メチルセドリルケトン、メチルβ-ナフチルケトン、メチルジヒドロジャスモネート、ローズフェノン、7-アセチル-1,2,3,4,5,6,7,8-オクタヒドロ-1,1,6,7-テトラメチルナフタレン、アセト酢酸-m-キシリダイド、アセト酢酸-o-トルイダイド、アセトシリンゴン、アセチルトリエチルシトレート、ベンゾフェノン、ベンジルベンゾエート、ベンジルカプリレート、ベンジルシンナメート、ベンジルオイゲノール、ベンジルラウレート、ベンジルメチルチグレート、ベンジルフェニルエーテル、ベンジルフェニルアセテート、ベンジルサリチレート、ゲラニルアントラニレ-ト、ゲラニルヘキサノエート、ゲラニルシクロペンタノン、ゲラニルフェニルアセテート、ヘキシルフェニルアセテート、イコサン、インダン、シンナミルブチレート、シンナミルフェニルアセテート、ヘキセニルベンゾエート、シトラールジエチルアセタール、イオノン、イソアミルベンゾエート、リナリルオクタノエート、1-メンチルサリチレート、シトロネリルアントラニレート、ジメチルフェネチルカルビニルイソブチレート、ジフェニルオキシド、ドデシルブチレート、エチルバニレート、エチルバニリン、メンチルイソバレレート、メトキシエチルフェニルグリシデート、メチル2,4-ジヒドロキシ-3,6-ジメチルベンゾエート、ネロリジルアセテート、ネリルイソバレレート、オクテニルシクロペンタノン、オクチルカプリレート、フェネチルイソアミルエーテル、フェネチルオクタノエート、フェネチルフェニルアセテート、エチルバニリンアセテート、エチルバニリンプロピレングリコールアセタール、エチルヘキシルパルミテート、オイゲニルベンゾエート、ファルネソール、ファルネシルアセテート、ファルネシルメチルエーテル、ホルムアルデヒドシクロドデシルメチルアセタール、ホルミルエチルテトラメチルテトラリン、フルフリルベンゾエート、γ-ドデカラクトン、フェネチルサリチレート、フェノキシエチルプロピオネート、フェニルベンゾエート、フェニルジスルフィド、サンタリルブチレート、テトラヒドロ-プソイドイオノン、テオブロミン、バレンセン、カンファー、ダマスコン等のモノテルペン系ケトン、ネラール、ペリラアルデヒド等のモノテルペン系アルデヒド、シンナミルフォーメート、ゲラニルフォーメート等のエステル化合物、フェニルエチルアルコール、アセトフェノン、アリルカプロネート、アミルシンナミックアルデヒド、アミルサリシレート、ベンズアルデヒド、ベンジルアセテート、ベンジルアルコール、カンファー、シンナミクアルコール、クマリン、ジハイドロリナロール、ジハイドロミルセノール、ジフェニルオキサイド、エチル-2-メチルブチレート、ヘディオン、ヘキサノール、シス-3-ヘキサノール、イソアミルアセテート、リリアール、メチルベンゾエート、メチルイオノン、メチルサリシレート、α-ピネン、β-ピネン、ローズオキサイド、ターピネオール、γ-ノナラクトン、γ-ウンデカラクトン、及びバニリン等が挙げられる。また、フローラル系香料、柑橘系香料、種々の精油類も使用可能であり、例えば、シトロネラ油、オレンジ油、レモン油、ライム油、ユズ油、ラベンダー油、ペパーミント油、シナモン油、ユーカリ油、レモンユーカリ油、ヒバ油、グレープフルーツ油、シダーウッド油、ゼラニウム油、タイムホワイト油、ハッカ油、ジャスミン油、檜油、緑茶精油、ネロリ油、ベルガモット油、プチグレン油、レモングラス油、バニラ油、カモミール油、ロージマリー油、セージ油、ジンジャー油、イランイラン油、ミント油、ローズ油、リリー油、ライラック油、カルダモン油、レモングラス油、ネロリ油、サンダルウッド油、アニス油、キャラウェイ油、アンバー油、シベット油、カストリウム油、グローブ油、ヨモギ油、及びベチパー油等が挙げられる。さらには、麝香等の動物から採取される動物系香料も使用可能である。
本発明の使い捨てカイロは、上記した鉄粉、活性炭、塩類、吸水性樹脂、及び水を含む発熱組成物、並びに香料とともに、活性炭による香料の吸着を抑制する「香料吸着抑制剤」を含有する。香料吸着抑制剤は、活性炭への香料の吸着を抑制する機能を有するものである。使い捨てカイロの原材料に香料吸着抑制剤を添加しておくと、当該使い捨てカイロにさらに香料を追加した場合、香料が活性炭に吸着され難くなり、活性炭への吸着を免れた香料が使い捨てカイロの外部に発散され、芳香効果を発揮させることができる。また、香料吸着抑制剤は、活性炭の酸素吸着効果を大きく阻害するものではないため、使い捨てカイロ内に空気中の酸素が確実に取り込まれ、鉄粉と酸素との酸化発熱反応がスムーズに進行し、使い捨てカイロの使用初期から安定した発熱を生じさせることができる。そして、使い捨てカイロの使用後期になると鉄粉は殆どが酸化されて消費されているため、鉄粉由来の不快な臭いは殆ど生じることなく、生じたとしても僅かに感じる程度の臭気となっている。
本発明の使い捨てカイロの原材料である発熱組成物、香料、及び香料吸着抑制剤は通気性を有する収納袋に封入される。そのような収納袋は、通気性を有し、発熱組成物等の原材料が漏出せず、カイロの発熱に耐え、容易には破れないような強度の収納袋であれば特に限定はされず、従来の使い捨てカイロに用いられてきた収納袋を用いることができる。
第一実施形態の使い捨てカイロは、通気性を有する収納袋に、鉄粉、活性炭、塩類、吸水性樹脂、及び水を含む発熱組成物と、香料と、活性炭への香料の吸着を抑制する香料吸着抑制剤とを封入したものである。図1は、第一実施形態に係る使い捨てカイロにおける活性炭、香料、及び香料吸着抑制剤の挙動について説明するモデル図である。図1(a)は、香料吸着抑制剤を含有しない従来の使い捨てカイロのモデル図である。図1(b)は、香料吸着抑制剤を原材料に含有した本発明の使い捨てカイロのモデル図である。図1(a)及び図1(b)において、使い捨てカイロの収納袋1を挟んで下側を使い捨てカイロの内側(すなわち、原材料が充填されている側)とし、上側を使い捨てカイロの外側(すなわち、外気が存在する側)とする。図1(a)及び図1(b)中に示す黒点は空気中の酸素2であり、白抜き円は活性炭3であり、白抜き四角は香料4である。図1(b)中に示す白抜き三角は香料吸着抑制剤5である。なお、発熱組成物の構成成分である鉄粉、塩類、吸水性樹脂、及び水は、説明の便宜上省略する。
第二実施形態の使い捨てカイロは、香料を付着又は含有させた通気性を有する収納袋に、鉄粉、活性炭、塩類、吸水性樹脂、及び水を含む発熱組成物と、活性炭への香料の吸着を抑制する香料吸着抑制剤とを封入したものである。図2は、第二実施形態に係る使い捨てカイロにおける活性炭、香料、及び香料吸着抑制剤の挙動について説明するモデル図である。図2(a)は、香料吸着抑制剤を含有しない従来の使い捨てカイロのモデル図である。図2(b)は、香料吸着抑制剤を原材料に含有した本発明の使い捨てカイロのモデル図である。図2(a)及び図2(b)において、使い捨てカイロの位置関係(内側及び外側)、及び各参照符号が意図する物質は、図1(a)及び図1(b)と同様である。また、図2(a)及び図2(b)においても、鉄粉、塩類、吸水性樹脂、及び水は、説明の便宜上省略してある。
使い捨てカイロのヨウ素吸着能について、JIS K1474に準拠した方法により評価した。具体的には、以下の手順〔1〕~〔6〕を実施した。
〔1〕ヨウ素吸着後の残留濃度範囲が2.5g/Lを含むように試料を量り取り、当該試料を均一になるまで粉砕した。
〔2〕粉砕した試料を褐色共栓付フラスコ100mLに移し入れ、これに0.05mol/Lのヨウ素溶液を50mL入れて密封した。
〔3〕室温下、振盪機を用いて約15分間、210回/分で振盪し、試料にヨウ素を吸着させた。
〔4〕振盪後の試料の固形分を遠心分離機で分離した。
〔5〕遠心分離後の試料の上澄み液10mLを量り取り、0.1mol/Lのチオ硫酸ナトリウム溶液を用いて滴定した。
〔6〕ヨウ素の黄色が薄くなったときに指示薬として1重量%のでんぷん溶液1mLを添加して更に滴定を続け、青色が消失したときを終点として滴定を終了した。
以上の操作による滴定量から、試料1g当たりのヨウ素吸着量(mg/g)を算出した。
10人の被験者に、各使い捨てカイロから発散される香料の芳香を感じることができるか否かを評価させた。評価は以下の基準による。
○;芳香を感じた被験者が8人以上である。
△;芳香を感じた被験者が4~7人である。
×:芳香を感じた被験者が3人以下である。
