Restricted components
| Component | Share |
|---|---|
| P-Anisyl alcohol | 0.1 % |
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.
