存在於柑橘類水果中,在室溫下為透明無色之液體,帶有強烈的柑橘類氣味,為 chiral molecule (旋光液晶分子/手徵性分子)。基於環境保護等因素,Limonene 這類油精逐漸用以作為清潔用品中之有機溶劑,以取代礦物油[1]。

D-limonene 呈柑橘類香味,常作為芳香添加用途,常見於個人衛浴用品中,並可作為植物性殺蟲劑成份[1]。

L-limonene 主要亦作為芳香添加用途,但其香味與 D-limonene 不太相同,偏向松脂類的香味[1]。

Rating: POOR
Categories: Fragrance: Synthetic and Fragrant Plant Extracts, Sensitizing
Chemical constituent of many natural fragrant ingredients, notably citrus oils such as lemon (d-limonene) and pine trees or species of the mint family (l-limonene).

Topically, limonene can cause sensitivity and is best avoided. Also, because of its penetration-enhancing effects on skin, it’s particularly important to avoid products that contain limonene plus other skin sensitizers like denatured alcohol.
