EC Requests Scientific Opinion on Titanium Dioxide in Cosmetic Products

The Scientific Committee on Consumer Safety (SCCS) announced on June 22, 2022, that the European Commission (EC) asked that it reassess the safety of titanium dioxide with a focus on genotoxicity and exposure via the inhalation and oral route (lip care, lipstick, toothpaste, loose powder, hair spray) “since the currently available scientific evidence supports an overall lack of dermal absorption” of titanium dioxide particles. The request notes that titanium dioxide is authorized...

OECD Publishes New Test Guidelines for Nanomaterials

On June 30, 2022, the Organization for Economic Cooperation and Development (OECD) published six new Test Guidelines (TG) and ten updated or corrected TGs. The new TGs include the first two harmonized methods for measuring certain nanomaterial-specific physical-chemical properties. According to OECD, these harmonized methods were developed to respond to regulatory needs in member and adhering countries, specifically for manufactured nanomaterials. The development of these TGs was...

EPA Research Team Develops Framework to Determine What Products to Classify and Evaluate as Nanopesticides

According to a May 9, 2022, news item published by the U.S. Environmental Protection Agency (EPA), “Advancing EPA’s Understanding of the Next Generation of Pesticides,” over the past decade, EPA “has received an increasing number of pesticide product applications that potentially contain nanomaterials.” The article notes that EPA’s current pesticide review method was not designed for nanomaterials, so each product is reviewed on a case-by-case basis. An EPA research team led by EPA...
