Safety Profile
USE WITH AWARENESSWhat Does Siparuna guianensis oil Smell Like?
Siparuna guianensis oil unfolds with an initial burst of green, herbaceous notes reminiscent of crushed leaves and damp forest floors. The heart reveals a surprising warmth – a woody, slightly camphoraceous character that evolves into a dry, earthy base. The overall impression is of a living rainforest, with subtle citrusy undertones that prevent it from becoming too heavy. Unlike many essential oils, it maintains a delicate balance between freshness and depth throughout its dry-down.

Chemistry, Properties & Perfumer Guide
The Chemistry
Siparuna guianensis oil is a complex mixture of terpenes and sesquiterpenes, with the exact composition varying by geographical origin. Major components typically include limonene, β-caryophyllene, and germacrene D. The oil is obtained through steam distillation of the plant’s leaves and twigs. The presence of oxygenated sesquiterpenes contributes to its unique olfactory profile and distinguishes it from more common essential oils.
