Regulatory status
Restricted components
| Component | Share |
|---|---|
| D-Limonene | 1.5 % |
IFRA regulated substances declared for this material. For naturals — which are mixtures of many molecules — the interactive index derives the effective maximum concentration per category from them. On single molecules these shares are purity traces from the supplier specification; they are far too small to limit use and are therefore not counted.
EU allergen declaration
| Substance | Share |
|---|---|
| Pinene | 5 % |
| Limonene | 1.5 % |
Substances that must be named in the ingredient list under Annex III of Regulation (EC) 1223/2009, as amended by Regulation (EU) 2023/1545. Where a range was given, the upper bound is shown.
All figures on this page are guide values collected from public reference works and supplier declarations. They differ between batches, origins and qualities. The data sheet of your own supplier is always the authoritative document for the material you actually use.
