具体的に、介護臭の消臭効果の評価は、本発明の疑似介護臭組成物に被検体（即ち、消臭成分）を作用させて臭いをかぎ、被検体を作用させる前の疑似介護臭組成物の臭いと比較することにより行うことができる。具体的には、疑似介護臭組成物を数段階に希釈し、各濃度の臭い標準サンプルを調製する。そして、被検体を作用させた後の疑似介護臭組成物の臭いを標準サンプルと照合し、消臭効果を官能評価により判定すればよい。官能評価は、１〜２０人のパネラーにより行うのが好ましく、３〜１０段階で評価するのが好ましい。 Specifically, the evaluation of the deodorizing effect of the care odor is performed by using the pseudo-care odor composition of the present invention by causing the subject (that is, the deodorant component) to act to smell the pseudo-care odor before the subject is acted on. This can be done by comparing with the odor of the composition. Specifically, the pseudo care odor composition is diluted in several stages to prepare odor standard samples of various concentrations. Then, the odor of the pseudo care odor composition after the subject is acted on may be compared with a standard sample, and the deodorizing effect may be determined by sensory evaluation. The sensory evaluation is preferably performed by 1 to 20 panelists, and is preferably evaluated in 3 to 10 stages.
疑似介護臭組成物に被検体を作用させる方法としては、特に限定されないが、例えば、疑似介護臭組成物を含浸させた布等に対し、被検体を噴霧又は塗布する方法；疑似介護臭組成物を含浸させた布等を被検体に浸漬する方法；被検体を担体に担持させて、疑似介護臭組成物を含浸させた布等が設置された空間で、該被検体を蒸散させる方法等が挙げられる。 The method of causing the subject to act on the pseudo-care odor composition is not particularly limited. For example, the method of spraying or applying the subject to a cloth impregnated with the pseudo-care odor composition; A method of immersing a cloth or the like impregnated in a specimen; a method of evaporating the specimen in a space where the specimen is supported on a carrier and a cloth or the like impregnated with a pseudo care odor composition is installed Can be mentioned.
また、上記のような官能試験によらず、臭い成分をＧＣ−ＭＳ等の化学的及び／又は物理的手法により分析し、被検体を作用させる前の疑似介護臭組成物と被検体を作用させた後の疑似介護臭組成物とを比較することにより、介護臭の消臭効果を評価してもよい。具体的には、疑似介護臭組成物を標準物質（スタンダード）として用い、あらかじめ検量線を作成する。この検量線を使用して、被検体を作用させた後の疑似介護臭組成物の臭い成分のピークを同定し、その量を測定すればよい。 In addition, the odorous component is analyzed by chemical and / or physical techniques such as GC-MS, and the pseudo-care odor composition and the subject before the subject is allowed to act, regardless of the sensory test as described above. You may evaluate the deodorizing effect of a care odor by comparing with the pseudo care odor composition after it. Specifically, a calibration curve is prepared in advance using the pseudo care odor composition as a standard substance (standard). Using this calibration curve, the peak of the odor component of the pseudo care odor composition after the subject is allowed to act can be identified and the amount thereof can be measured.
本発明の介護臭の消臭効果の評価方法は、消臭剤等の開発において使用することができる。 The method for evaluating the deodorizing effect of the care odor of the present invention can be used in the development of deodorants and the like.

［介護臭との類似性の評価］
以下に示す介護臭との類似性の評価基準に従って、評価用サンプルを採点した。
≪介護臭の類似性の評価基準≫
５：非常に類似性がある。
４：類似性がある。
３：やや類似性がある。
２：ほとんど類似性がない。
１：類似性はない。
[Evaluation of similarity to care odor]
The evaluation samples were scored according to the following evaluation criteria for similarity to the care odor.
≪Evaluation criteria for similarity of care odor≫
5: Very similar.
4: There is similarity.
3: Somewhat similar.
2: Almost no similarity.
1: There is no similarity.
表１に示す結果から、本発明を適用した実施例１〜６の疑似介護臭組成物は、成分（Ａ）を含まない比較例１〜３と比較して、介護臭との類似性において優れることが確認できた。また、本発明の疑似介護臭組成物は、実施例１〜３のように臭気強度が強くない場合であっても、介護臭との類似性を実感できることを確認できた。一方、成分（Ａ）を含まない比較例１〜３は、介護臭との類似性においてやや劣ることが確認された。以上の結果から、本発明の疑似介護悪臭組成物は、介護臭をより忠実に再現できることを確認できた。 From the results shown in Table 1, the pseudo care odor compositions of Examples 1 to 6 to which the present invention is applied are superior in similarity to care odor compared to Comparative Examples 1 to 3 that do not contain the component (A). I was able to confirm. Moreover, even if it was a case where odor intensity | strength is not strong like Examples 1-3, the pseudo care odor composition of this invention has confirmed that the similarity with a care odor can be actually felt. On the other hand, it was confirmed that Comparative Examples 1-3 which do not contain a component (A) are somewhat inferior in the similarity with a care odor. From the above results, it was confirmed that the pseudo care odor composition of the present invention can reproduce the care odor more faithfully.
（２）疑似介護臭組成物を利用した消臭効果の評価
＜試験サンプルの作成＞
実施例５に記載した割合で成分（Ａ）〜（Ｃ）とプロピレングリコールを混合し、疑似介護臭組成物を調製した。調製した疑似介護臭組成物を９０ｍｍ×９０ｍｍの評価用ろ紙に０．６ｇ滴下し、評価用サンプルとした。
(2) Evaluation of deodorizing effect using simulated nursing odor composition <Preparation of test sample>
Components (A) to (C) and propylene glycol were mixed in the proportions described in Example 5 to prepare a pseudo care odor composition. 0.6 g of the prepared pseudo-care odor composition was dropped onto a 90 mm × 90 mm evaluation filter paper to obtain an evaluation sample.
＜消臭剤の調製＞
安息香酸ナトリウム０．１％、柿タンニン５％、エタノール５％、水（残量）を混合して消臭剤を調製した。
<Preparation of deodorant>
A deodorant was prepared by mixing 0.1% sodium benzoate, 5% tannin, 5% ethanol, and water (remaining amount).
＜臭気強度の評価基準＞
上記［臭気強度の評価］と同様の基準を用いて評価した。
<Evaluation criteria for odor intensity>
Evaluation was performed using the same criteria as in the above [Evaluation of odor intensity].
＜消臭試験＞
試験サンプルを２枚用意し、一方のみに調製した消臭剤を市販のトリガー式スプレー容器に収納して３回スプレーし、試験サンプルをそれぞれ異なる１０リットルのデドラーバッグに入れ、３０分間放置した後、バッグ内の臭気強度から２枚のサンプルの介護臭の強さを評価した。
<Deodorization test>
Prepare two test samples, store the deodorant prepared on only one side in a commercially available trigger type spray container, spray three times, put each test sample in a different 10 liter dedora bag and leave it for 30 minutes, The strength of the care odor of the two samples was evaluated from the odor intensity in the bag.
その結果、消臭剤をスプレーしなかったサンプルの臭気強度は３．８であったが、消臭剤をスプレーしたサンプルの臭気強度は２．７に低下しており、消臭効果の評価用の介護臭指標物質及び消臭効果評価法として適したものであると判断した。 As a result, the odor intensity of the sample not sprayed with the deodorant was 3.8, but the odor intensity of the sample sprayed with the deodorant was reduced to 2.7. It was judged to be suitable as a care odor indicator substance and deodorant effect evaluation method.
本発明の疑似介護臭組成物は、成分（Ａ）を含有するため、介護臭をより忠実に再現した疑似介護臭組成物となる。この疑似介護臭組成物を用いれば、介護臭の消臭効果の評価をすることができる。
以 上
Since the pseudo care odor composition of this invention contains a component (A), it becomes the pseudo care odor composition which reproduced care odor more faithfully. If this pseudo care odor composition is used, the deodorizing effect of the care odor can be evaluated.
that's all
