Allergen
Declared fragrance allergen

This substance is on the EU list of fragrance allergens that must be named individually in the ingredient list, rather than being covered by the word "parfum", once it exceeds 0.001% in a leave-on product or 0.01% in a rinse-off product.

Declaration is a labelling duty under Article 19, not a restriction on use. See the allergen record

What Annex III means for Limonene

Limonene is a restricted substance under Annex III of EU Cosmetics Regulation 1223/2009. Its use in cosmetics is only permitted under the specific conditions set out in the entry above, including applicable concentration limits, product type restrictions and required warning statements.

When including this substance in a formulation, all conditions — maximum concentration, product scope and warning labels — must be met simultaneously. Compliance with one condition does not override the others.

This record is linked to 2 CosIng inventory ingredients for name and identifier cross-reference. The page also surfaces 12 related annex records with overlapping identifiers, annex logic or naming patterns.

Compliance checklist

  • Document conditions of use in the Product Information File (PIF).
  • This substance is a regulated fragrance allergen. Declare it on the label by INCI name above 0.001% in leave-on or 0.01% in rinse-off products.

Frequently asked questions

Limonene is listed in Annex III of EU Regulation 1223/2009 as a restricted substance. It may only be used under the conditions specified in the entry, including any maximum concentration, product type limitation and required warning statements shown above.

CAS 138-86-3/ 7705-14-8; 5989-27-5; 5989-54-8 is the unique numerical identifier assigned to Limonene by the Chemical Abstracts Service. In cosmetic compliance work, the CAS number is used to cross-reference the substance across regulatory databases, raw material specifications and safety assessment reports. Multiple EU annex entries may share the same CAS number if the same substance appears under different conditions or in different annexes.

Yes. Limonene is on the EU list of regulated fragrance allergens. It must be declared on the cosmetic product label by its INCI name when present above 0.001% in leave-on products or above 0.01% in rinse-off products, as required by EU Cosmetics Regulation 1223/2009.

Use the INCI Checker tool on this site to paste your full ingredient list (INCI) and scan it against all Annex II–VI entries.
