Description
乳酸のメンチルエステル(下記:LME)
【0002】
【化1】
【0003】
は、体の皮膚および粘膜に対して生理学的冷却作用を示す化合物であり、この化合物は、長く持続する生理学的冷却作用が望まれる消費製品、例えば半贅沢消耗品、例えばチュインガム、噛みたばこ、たばこ、アイスクリーム、菓子および飲料など、および薬学調剤、ボディーケア組成物または化粧品調剤、例えば歯磨き組成物、口洗浄剤、香料、粉剤、ローション、軟膏、オイル、クリーム、シェービングローションおよびシャンプーなどで使用可能である。
【0004】
LMEは、通常、酸触媒を用いて市販L−乳酸をL−メントールでエステル化することで製造される。
【0005】
適切なエステル化用触媒は、例えば「有機化学方法」(Methoden der Organischen Chemie)(Houben−Weyl)、VIII巻、517頁、Georg Thieme Verlag、Stuttgart 1952などに記述されている。好適な触媒には、無機酸、例えば硫酸、燐酸および酸性土類など、有機酸、例えばメタンスルホン酸およびp−トルエンスルホン酸など、および酸性イオン交換体などが含まれる。触媒の推奨量は乳酸1モル当たり0.0001−0.1モル、好適には0.01−0.05モルである。
【0006】
通常、反応混合物を中和して洗浄した後、蒸留で精製を行うことにより、大部分の用途で用いるに適切な純度(97から98%)でLMEが得られている。その溜分は、LMEに加えて、D−乳酸のL−メンチルエステル(1−2%)とL−メントール(約1%)を含有する。その生成物は、これを数週間に渡って貯蔵している間に、意図した大部分の用途で使用不能にするほどの刺激臭を発するようになる。その生成物がこのように変化する理由は未知である。
【0007】
アルカリ金属の重炭酸塩を存在させると驚くべきことに生成物がそのように望ましくなく変化することが起こらないことをここに見い出した。
【0008】
従って、本発明は、
A. L−乳酸のL−メンチルエステルと、
B. 1重量部のA当たり0.0001から0.05重量部のアルカリ金属重炭酸塩、
の混合物に関する。
【0009】
本発明に従う混合物は数カ月に渡る貯蔵に安定であり、匂いが貯蔵中に全く変化しないことが分かる。
【0010】
本発明に従う混合物は、考えられ得る如何なる方法で調製されてもよく、例えば2つの成分(好適には粉末形態)を乾燥混合するか、或は両方の成分に適した溶媒、例えば水メタノールまたは水アセトンなどに上記成分を溶解させてその溶媒を除去することなどで調製可能である。
【0011】
好適な態様に従い、好適には蒸留を行うに先立ってLMEの再結晶を添加剤Bの存在下で行うが、この場合、LMEで用いる溶媒は必ずしもまた同時にBの溶媒でなくてもよい、言い換えれば、本発明の目的で、溶解しているLMEに添加剤Bを溶解させる必要はなく、その溶解しているLMEに添加剤Bを分散させてもよく、好適には勿論添加剤Bを微細形態で分散させてもよく、そしてその後、それをLME結晶と一緒に分離してもよい。
【0012】
LMEの好適な溶媒はアセトンであり、好ましくは、結晶化に適した溶媒/LMEの重量比は0.5から10、好適には1から3である。
【0013】
ナトリウムの重炭酸塩およびカリウムの重炭酸塩が、添加剤Bとして好適に使用可能である。
【0014】
本発明に従う混合物は、大部分の用途で、添加剤Bを前以て除去することなく使用可能である。
【0015】
以下に示す実施例のパーセントデータは各場合とも重量パーセントに関し、部は重量部である。
【0016】
【実施例】
ガスクロに従い、
L−乳酸のL−メンチルエステルを97.3%、
D−乳酸のL−メンチルエステルを1.4%および
L−メントールを0.8%、
含有する蒸留LME(1000部)を、重炭酸ナトリウムを1部添加しておいた500部のアセトンに40℃で溶解させた。この混合物を氷浴で冷却して12℃で種晶を加える。次に、この混合物を2時間かけて(撹拌しながら)5℃に冷却する。結晶スラリーを濾別して空気中で乾燥させる。
【0017】
ガスクロに従い、その結果として生じた生成物はL−乳酸のL−メンチルエステルを99.7%含有する。これは感覚的特性変化を起こすことなく数カ月に渡って貯蔵可能である。
