Caution
Sensitization risk High

Registered with the FDA (172.510), this oil carries a notable risk profile. It can cause skin irritation, allergic skin reactions, and serious eye irritation. Ingestion is harmful and potentially fatal if it enters airways. While fresh, it is considered non-irritating, but its irritancy increases upon aging, mandating refrigeration and strict adherence to shelf-life guidelines. Due to the presence of IFRA restricted components and general safety concerns, it is not recommended for use in children under 7, or by pregnant or breast-feeding individuals.
