Chemical Properties |
Rose Oxide forekommer små mengder, hovedsakelig som den levorotatory cis-formen, i essensielle oljer (f.eks. Bulgarsk roseolje og geraniumolje). Kommersielle syntetiske produkter er enten optisk aktive eller inaktive blandinger av cis- og trans-isomerer. De sensoriske egenskapene avhenger av utgangsmaterialet og metoden for syntese. De er fargeløse væsker med sterk lukt som Geranium og roseolje. |
