What IFRA restrictions and allergen declarations apply to this tea tree oil?
Tea tree oil contains fragrance allergens that must be declared above EU labeling thresholds, and IFRA restricts its use in cosmetics due to skin-sensitization risk. The EU also limits it to 1% in leave-on products.
IFRA & Allergen Status

| IFRA 51 | Tea tree oil is restricted for skin-sensitization (use limits set by IFRA) |
| EU cosmetics limit | Annex III: max 1% in leave-on products |
| Allergen certificate | Provided with each shipment |
- Because the oil is a known sensitiser, IFRA and EU rules set concentration limits for cosmetics — especially leave-on products
- Terpinen-4-ol, limonene and linalool are all on the EU 1223/2009 Annex III allergen list, so declare them when above threshold
- For skin products, always dilute (typically ≤1% in leave-on cosmetics per EU rule)
- The allergen declaration sheet listing all Annex III allergens present is supplied with every order
- Finished cosmetics require a formal product safety assessment by the responsible person
