About
A monoterpene found naturally in essential oils with a pleasant citrus-herb aroma, requiring IFRA restrictions due to skin sensitization.
Alpha-phellandrene is a cyclic monoterpene present in essential oils like tea tree, eucalyptus, and star anise. The EU's IFRA program has reviewed phellandrene and requires sensitizer disclosure at defined concentrations. While naturally occurring, the compound's oxidation products can increase allergenic risk, requiring careful storage and formulation control.
Known concerns
- Skin sensitizer (IFRA restricted)
- Oxidation products increase allergen risk
- IFRA concentration limits apply
