- Keep leave-on formulations at ≤1% undiluted oil (EU Annex III; TGA lists TGO 97 at max 1%) to manage sensitization risk
- Stabilize with antioxidants if your formula exposes the oil to light/air long-term
- Combine with a chelator and appropriate emulsifier; the oil is oil-soluble and needs proper emulsification in aqueous systems
- Verify pH stability and avoid high-heat processing steps that can degrade the terpenes
- Always validate the finished formula with a product safety assessment and patch testing
