In 2007 the FDA convened a task force to examine the scientific and regulatory challenges that accompany the growth in nanotechnology. Their report recommended: (1) the consideration of guidance that would clarify what information manufacturers should give the FDA about products and when the use of nanoscale ingredients may change the regulatory status of products; (2) that manufacturers contact the FDA early in the product development process; (3) that the FDA assess data needs for regulated nanotechnology products including biologic effects; (4) that the FDA develop their own body of inhouse experts to rapidly consider new advances in nanotechnology; and (5) that the FDA evaluate their current testing approaches to examine the safety, effectiveness, and quality of nanoscale products. New regulations were also proposed with regard to sunscreen labeling, most notably, a rating system for UVA protection.
