May 23, 2007 Office of Pesticide Programs (OPP) Regulatory Public Docket (7502P) Environmental Protection Agency 1200 Pennsylvania Ave., NW Washington, DC 20460-0001 RE: Insect Repellent-Sunscreen Combination Products [EPA-HQ-OPP-2007-0087] Beyond Pesticides appreciates the prudent contemplation of insect repellent-sunscreen combination products EPA proposed in the reregistration eligibility decision (RED) for N,N-diethyl-meta-toluamide (DEET). We also appreciate this opportunity to share our concerns over these products. Beyond Pesticides interest in this issue lies in our effort to restrict pesticide use in a manner that protects public health and the environment, and to advance alternatives that eliminate dependency on toxic chemicals. We oppose the reregistration of all DEET-sunscreen combination products for the following reasons: 1. DEET exposure can result in negative health effects. As the agency notes, the registration of DEET is unusual in that it is one of few residential-use pesticides that is applied directly to the skin. The result is that the public is being exposed to a pesticide that has the ability to cause in lab animals increased fetal loss, bone and skeleton abnormalities in the offspring of rabbits, birth defects in birds, reduction in size of the testes and degeneration, and has produced abnormal sperm with reduced motility. Additionally, the public is directly applying a chemical to their skin that is demonstrated to cross the placenta and move into fetal blood in humans, has the ability to cause mutagenicity and oxidative stress, can decrease sensory and motor skills, causes skin irritation and kills brain cells.1 2. Sunscreen exposure can result in negative health effects. -

FDA Proposes Sunscreen Regulation Changes February 2019
FDA Proposes Sunscreen Regulation Changes February 2019 The U.S. Food and Drug Administration (FDA) regulates sunscreens to ensure they meet safety and eectiveness standards. To improve the quality, safety, and eectiveness of sunscreens, FDA issued a proposed rule that describes updated proposed requirements for sunscreens. Given the recognized public health benets of sunscreen use, Americans should continue to use broad spectrum sunscreen with SPF 15 or higher with other sun protective measures as this important rulemaking eort moves forward. Highlights of FDA’s Proposals Sunscreen active ingredient safety and eectiveness Two ingredients (zinc oxide and titanium dioxide) are proposed to be safe and eective for sunscreen use and two (aminobenzoic acid (PABA) and trolamine salicylate) are 1 proposed as not safe and eective for sunscreen use. FDA proposes that it needs more safety information for the remaining 12 sunscreen ingredients (cinoxate, dioxybenzone, ensulizole, homosalate, meradimate, octinoxate, octisalate, octocrylene, padimate O, sulisobenzone, oxybenzone, avobenzone). New proposed sun protection factor Sunscreen dosage forms (SPF) and broad spectrum Sunscreen sprays, oils, lotions, creams, gels, butters, pastes, ointments, and sticks are requirements 2 proposed as safe and eective. FDA 3 • Raise the maximum proposed labeled SPF proposes that it needs more data for from SPF 50+ to SPF 60+ sunscreen powders. • Require any sunscreen SPF 15 or higher to be broad spectrum • Require for all broad spectrum products SPF 15 and above, as SPF increases, broad spectrum protection increases New proposed label requirements • Include alphabetical listing of active ingredients on the front panel • Require sunscreens with SPF below 15 to include “See Skin Cancer/Skin Aging alert” on the front panel 4 • Require font and placement changes to ensure SPF, broad spectrum, and water resistance statements stand out Sunscreen-insect repellent combination 5 products proposed not safe and eective www.fda.gov. -

EWG Petitions CDC to Conduct Biomonitoring Studies for Common Sunscreen Chemicals
EWG Petitions CDC To Conduct Biomonitoring Studies for Common Sunscreen Chemicals May 22, 2019 To: U.S. Department of Health and Human Services Centers for Disease Control and Prevention National Center for Environmental Health Agency for Toxic Substances and Disease Registry 4770 Buford Hwy, NE Atlanta, GA 30341 Patrick Breysse, Ph.D., CIH Environmental Working Group (EWG), a nonprofit research and advocacy organization with headquarters in Washington, D.C., is petitioning the Centers for Disease Control and Prevention to add common sunscreen chemicals to the CDC’s Biomonitoring Program. EWG has been doing research on sunscreen ingredients since 2007, helping to educate the public about the importance of using sunscreens for health protection, as well as providing information about health risks that may be associated with certain ingredients used in sunscreen products. In response to a significant increase in the use of sunscreens in the United States and the associated increased potential for systemic exposure to the ingredients in these products, in February 2019, the Food and Drug Administration proposed a new rule for sunscreen products.1 The proposed rule would require sunscreen active ingredients to be assessed for their propensity to absorb through the skin and overall safety. Recently, the FDA completed tests on the absorbance of four common sunscreen active ingredients: avobenzone, oxybenzone, octocrylene, and ecamsule. As reported in a study published by the Journal of American Medical Association in May 2019,2 application of all four tested sunscreen ingredients resulted in plasma concentrations that exceeded the 0.5 ng/mL threshold proposed by the FDA for waiving systemic carcinogenicity studies as well as developmental and reproductive toxicity studies. -

Sun Protection
DRUG NEWS Recommending the Best Sun Protection Clinical Pearls: o Recommend a “broad-spectrum” sunscreen – one that covers UVB, UVA1, and UVA2. o Recommend SPF 30-50 o Advise on non-pharmacological sun protection methods o Emphasize proper sunscreen application technique o Emphasize skin protection when taking drugs known to cause photosensitivity. Familiarize yourself with known implicated drugs by referring to appendix 2. Background 1-4 The sun emits 3 types of ultraviolet (UV) radiation: UVC (100-290 nm), UVB (290-320 nm), and UVA (320 -400 nm). UVA rays can be further divided into the shorter UVA2 rays and the longer UVA1 rays. UVC rays, the shortest rays, are completely absorbed by the ozone layer, whereas UVB rays penetrate the epidermis and UVA rays, the longest rays, penetrate into the dermis. The main consequence of UVB irradiation is sunburn, but can also include immunosuppression and skin cancer. Consequences of UVA radiation include: phototoxicity (i.e. involvement in drug-induced sun sensitivity reactions), photo-aging, immunosuppression, and skin cancer. What is SPF? 2,5,6,7 It is easy to be misled by Sun Protection Factors (SPF). SPF is assessed through a standardized test by finding the ratio of the minimal dose of solar radiation that produces perceptible erythema (i.e., minimal erythema dose) on sunscreen-protected skin compared with unprotected skin. Sunburn is caused primarily by UVB rays (and shorter UVA2 rays), and thus SPF indicates mostly UVB protection. However, UVA protection is equally important since it is responsible for photo-aging and cancer. Therefore, it is important to look for the phrase “broad spectrum” when choosing a sunscreen as broad spectrum indicates both UVB and UVA protection. -
