Welcome to Rules and Reactions, a joint podcast from Wiley’s Environmental and FDA Regulatory practices. Hosted by Lauren Petrin and Dr. Alex Stanton, the podcast combines legal and scientific perspectives on evolving federal and state regulations that are shaping innovation in environmental policy and FDA-regulated industries. The inaugural episode shines a light on sunscreen – and the FDA’s recent proposal to add the first new active ingredient in over 25 years. We break down how the product is regulated in the United States and what this historic shift could mean for future innovation.
