What IFRA restrictions and allergen declarations apply to this sweet orange oil?
Sweet orange oil contains d-limonene, a fragrance allergen that must be declared above labeling thresholds. IFRA 51 restricts certain citrus oils for phototoxic risk — sweet orange (cold-pressed) is approved with limited phototoxicity restrictions in leave-on cosmetics.
IFRA & Allergen Status
| Item | Detail |
|---|---|
| Main allergen | d-Limonene (CAS 5989-27-5), typically 85-96% of the oil |
| EU/UK allergen labeling threshold | ≥0.001% in leave-on, ≥0.01% in rinse-off (EU 1223/2009) |
| IFRA 51 phototoxicity | Cold-pressed sweet orange oil is restricted in leave-on skin products: max 4.44% in cream/body oil etc. (limit is generally not binding in practice because the oil oxidizes) |
| Allergen certificate | Provided with each shipment |
| Other potential allergens | Linalool, citral (traces) — declared when ≥10 ppm |
- Because limonene content is so high, any product containing more than ~0.01% sweet orange oil must declare 'd-Limonene' (Limonene) on the label
- Cold-pressed sweet orange oil has minimal furocoumarin content, so phototoxicity risk is far lower than for bergamot or lime; still, IFRA limits apply to leave-on cosmetics
- For safety, use properly stored, low-oxidized oil; oxidized limonene is a stronger sensitizer
- An allergen declaration sheet listing all EU 1223/2009 Annex III allergens present is supplied with every order
- For finished cosmetics, the responsible person must perform the formal product safety assessment
