发明内容
发明要解决的问题
然而,上述常规提出的冷感剂具有某种程度的冷感效果,但对于冷感效果等的持续性,仍未足够令人满意。此外,感觉刺激效果也需要进一步改善。
因此,本发明的目的是提供新型甲基薄荷醇衍生物,其不具有不好的刺激、特殊的气味、苦味等,且可被用作具有优秀持续性的清凉感或冷凉感的冷感剂或感觉刺激剂。
此外,本发明的另一个目的是提供含有新型甲基薄荷醇衍生物的冷感剂组合物和含有该冷感剂组合物的感觉刺激剂组合物。
此外,本发明的又一个目的是提供共混有该感觉刺激剂组合物的香料组合物,及共混有该感觉刺激剂组合物或该香料组合物的制品。
用于解决问题的方案
本发明人为达成上述目标,进行了深入研究,结果,他们发现作为由通式(1A)或通式(1B)表示的甲基薄荷醇衍生物的5,5-二甲基-2-异丙基环己烷衍生物或5,5-二甲基-2-异丙烯基环己烷衍生物具有强冷感效果,并且其还具有优秀的持续性,且可用作冷感物质和可进一步用作感觉刺激物质。此外,他们发现,例如,当l-薄荷醇被用作冷感剂时,所述甲基薄荷醇衍生物可缓和l-薄荷醇的刺激性气味。此外,他们发现在配混有包含含有冷感剂组合物(该冷感剂组合物含有由通式(1A)或通式(1B)表示的甲基薄荷醇衍生物)的感觉刺激剂组合物的香料组合物中,香料组合物的头香(top note)和余香性(lingering scent)增强,且给由香料组合物赋香的制品带来了高香质改善效果,从而基于上述发现完成了本发明。
