What usage rates and dilution ratios are recommended for this tea tree oil?
Recommended usage depends on the application — for leave-on cosmetics keep it at or below 1% (EU Annex III), for rinse-off products 0.1-1%, and for aromatherapy dilution 1-5% in a carrier.
Usage Rate Guidance
| Application | Recommended rate |
|---|---|
| Leave-on cosmetics (undiluted oil) | ≤1% (EU Annex III / TGA limit) |
| Rinse-off products (soap, shampoo, body wash) | 0.1-1% |
| Household cleaners / disinfectant blends | 0.5-2% |
| Aromatherapy massage (in carrier) | 1-5% of the blend |
| Inhalation / diffuser | 3-5 drops per diffuser session |
- The 1% leave-on cap reflects the oil's sensitization potential at higher undiluted levels — always dilute in leave-on skincare
- Never apply undiluted to skin or mucous membranes, and never ingest
- For oral-care products, use only within an approved oral formulation and regulatory framework
- Patch test on a small skin area before first cosmetic use
- Adjust dosing by your finished-product safety assessment, not just by aroma
