Proposed Harmonized Classification and Labeling Would Apply to Nanosized Titanium Dioxide

On May 31, 2016, the European Chemicals Agency (ECHA) began a public consultation on a harmonized classification and labeling (CLH) proposal submitted by France for titanium dioxide. See http://echa.europa.eu/harmonised-classification-and-labelling-consultation/-/substance-rev/13832/term The proposed entry in Annex VI of the Classification, Labeling, and Packaging (CLP) Regulation is "Carc. 1B, H350i." The CLH report states: "Based on available evidence and information in the registration dossier (e.g. mechanism of carcinogenicity, characterization of the particles), the proposed scope for the Annex VI entry is: ‘Titanium dioxide in all phases and phase combinations; particles in all sizes/morphologies.'" See http://echa.europa.eu/documents/10162/594bf0e6-8789-4499-b9ba-59752f4eafab The entry would apply for both fine particles and nanoparticles of titanium dioxide without any distinction in terms of morphology, crystal phase, and surface treatment. Comments are due July 15, 2016. ECHA states that comments can be submitted on general issues, for example on substance identification, physicochemical properties, and data sources. Comments can also be submitted on any unclarities in the text of the CLH dossier. After the public consultation, ECHA encourages the parties concerned to coordinate their involvement in the Committee for Risk Assessment (RAC) opinion-making process with the regular and sector-specific accredited stakeholder organizations.
