Between 2003 and 2010, sunscreen makers applied for FDA permission to use eight sun-filtering chemicals developed by European companies. Four of these – Tinosorb S, Tinosorb M, Mexoryl SX and Mexoryl XL – appear to be more effective than avobenzone, the most common UVA filter permitted by the FDA. The FDA’s failure to respond to these applications prompted Congress to pass the Sunscreen Innovation Act of 2014 (FDA 2014). This act requires the FDA to review new applications for sunscreen active ingredients within 300 days, but it doesn’t relax the standards companies must meet to prove new ingredients are both safe and effective.
