Frequently asked questions

Is styrene oxide safe for baby skin?

Hazard remains h=3 because of the harmonised carcinogen classification (H350). Mechanism rating m=2 reflects demonstrated animal reproductive/developmental toxicity and the reactive epoxide chemistry. Exposure for baby skin is increased by +1 vs adult because infant skin barrier immaturity and higher surface-area-to-weight ratio make dermal uptake more likely; therefore e=2 (moderate) if the ingredient were present on skin. Note: styrene oxide is not a normal cosmetic ingredient and is highly reactive; presence in finished cosmetic products would be unexpected and problematic. See ECHA harmonised classification and animal inhalation/developmental studies below.
