Ingredients in the formula
Recognised from the name. If a supplier files bergamot under a code, or your "lemon" is distilled, correct it here.
Found inside certificates
Phototoxic naturals declared inside an accord or base, matched by CAS or name.
Run the compliance check to read the certificates.
Calculation
X = usage ÷ limit per material; TFV is their sum; the formula may be at most 100 ÷ TFV of the product.
The eleven materials
IFRA phototoxic limits in fine fragrance and the CAS numbers used to recognise them.
Run the compliance check first; the label follows from it.
