On July 12, 2019, the European Food Safety Authority (EFSA) published in the EFSA Journal its “Scientific opinion on the proposed amendment of the EU specifications for titanium dioxide (E 171) with respect to the inclusion of additional parameters related to its particle size distribution.”  The opinion addresses the assessment of data provided by interested business operators in support of an amendment of the European Union (EU) specifications for titanium dioxide (E 171)...

An Advisory Group of 29 scientists from 18 countries met on March 25-27, 2019, to recommend priorities for the International Agency for Research on Cancer (IARC) Monographs program during 2020-2024.  The Advisory Group assessed the response to a public call for nominations and considered more than 170 unique candidate agents, including the recommended priorities remaining from a similar Advisory Group meeting convened in 2014.  The Advisory Group deliberated on all nominated agents both by...

On April 17, 2019, the Ministry of Ecological and Solidarity Transition issued a press release announcing that France will prohibit foods containing food additive E171 (titanium dioxide) from being placed on the market beginning January 1, 2020.  The press release cites the April 15, 2019, opinion from the Agence nationale de sécurité sanitaire de l’alimentation, de l’environnement et du travail (ANSES).  The expert group established by ANSES conducted a literature review on the...

The California Division of Occupational Safety and Health’s (Cal/OSHA) Health Effects Advisory Committee (HEAC) for the Development of Permissible Exposure Limits (PEL) will meet on June 4, 2019.  According to the meeting agenda, HEAC will discuss the selection of Priority 1 substances for HEAC review.  HEAC has posted a draft 2019 Priority 1 List consisting of ten chemical substances.  The draft List includes titanium dioxide, ultrafine (<100 nanometers...

The European Chemicals Agency (ECHA) announced on September 27, 2017, that the Committee for Risk Assessment (RAC) concluded on ten opinions for harmonized classification and labeling (CLH), including titanium dioxide.  In May 2016, France submitted a CLH proposal for titanium dioxide, stating that titanium dioxide should be considered as being potentially carcinogenic to humans when inhaled and thus be classified as category 1B-H350i.  France proposed that the classification...

An August 15, 2016, U.S. Environmental Protection Agency (EPA) blog item describes EPA’s research on sunscreens containing engineered nanomaterials and how they might change when exposed to chemicals in pool water.  According to EPA, many sunscreens contain titanium dioxide engineered nanomaterials, which are often coated with other materials such as aluminum hydroxide to shield skin from reactive oxygen species.  EPA researchers are testing to see whether swimming pool water degrades the...

Inhalation Toxicology has published an article entitled “Exposure assessment of workplace manufacturing nanosized TiO2 and silver,” which monitored the possible exposure to nanoparticles at workplaces that manufacture nano-titanium dioxide (TiO2) and nano-silver.  The abstract states: To estimate the potential exposure of workers, personal sampling, area monitoring, and real-time monitoring using a scanning mobility particle sizer (SMPS) and dust monitor were conducted at...
