The Food and Drug Administration (FDA) is issuing this document to address labeling and effectiveness testing for certain over-the counter (OTC) sunscreen products containing specified active ingredients and marketed without approved applications. This document addresses labeling and effectiveness testing issues raised by the nearly 2,900 submissions that we received in response to the sunscreen proposed rule of August 27, 2007 (2007 proposed rule). The document also identifies specific claims that render a product that is subject to this rule misbranded or would not be allowed on any OTC sunscreen product marketed without an approved application. The document does not address issues related to sunscreen active ingredients or certain other issues regarding the GRASE determination for sunscreen products. The document requires OTC sunscreen products to comply with the content and format requirements for OTC drug labeling contained in the 1999 Drug Facts final rule (published in the Federal Register of March 17, 1999, by lifting the delay of implementation date for that rule that we published on September 3, 2004).
