Safety Profile
The Cosmetic Ingredient Review (CIR) has classified this ingredient with 'insufficient data' regarding its overall safety profile. The Environmental Working Group (EWG) lists 'TORREYA CALIFORNICA (CALIFORNIA NUTMEG) EXTRACT' as 'RESTRICTED,' citing a complete absence of data for crucial safety concerns such as skin allergies, irritation potential, developmental and reproductive toxicity, and carcinogenic risk. Consequently, products aiming for EWG VERIFIED status cannot incorporate this ingredient without substantial further substantiation.
