BRUSSELS, BELGIUM (Oct. 24, 2:15 p.m. ET) — The European Commission has released its recommendation for a regulatory definition for nanomaterials. However, the Chemical Industries Association (CIA) has questioned the practicality of the definition and expressed concern that it would be difficult to integrate into existing legislation.
Anne-Gaelle Collot, head of environment at the CIA, said: “The [United Kingdom] is leading the way in nanomaterial innovation to meet challenges such as climate change, water scarcity and improving health, so we support the need for a definition of the term nanomaterial to enable consistency of approach for regulators and industry.
“We are concerned that we lack the standardized measurement techniques which will be important for establishing the legal certainty that particular substances are or are not nanomaterials and that the proposed definition will add unnecessary burden for companies, leading to added costs and less efficient use of resources.”
The global chemical industry, organized under the International Chemicals Industry Association (ICCA), has outlined requirements for a workable definition. It agrees with the commission recommendation that the definition should be based on the size of particles within substances. However, the chemical industry advocates using weight concentration, rather than particle number distribution, to determine the cut-off criterion for nanomaterials.
