Europe clears bemotrizinol (1999)
European regulators approved bemotrizinol for sunscreens, treating it as a cosmetic ingredient. Brands sold it under names including Tinosorb S and Parsol Shield. It became a common broad-spectrum filter across Europe and Asia.
European sunscreens gained a stable filter with strong UVA coverage well before US shoppers could buy it.
A widening gap opened between US and international sunscreen formulas that lasted more than 25 years.
The 27-year lag shows how differently the US and Europe regulate the same ingredient. Bemotrizinol was routine abroad long before the FDA cleared it.
