Regulatory status
Restricted components

| D-Limonene | 0.005 % |
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.
