Expression of Interest For Nanomaterial Risk Assessment: Refining And Validating Acceptable Variation In Nanoform Characterisers

Expression Of Interest For Nanomaterial Risk Assessment: Refining And Validating Acceptable Variation In Nanoform Characterisers. Description: The Contract Is Meant To Follow Up To On Previous Project Nanomaterial Risk Assessment: A Regulatory Way Forward For Sameness And Grouping Approaches Contracted In 2023. In The Previous Contract, A Framework Was Developed To Assess The Acceptable Variation Within Each Characteriser Of A Nanoform. That Project Aimed At Exploring Ways To Simplify Nanoforms Registration Process And, Ultimately, Its Associated Testing Burden. As An Outcome, A Series Of Binary Decision Trees And Respective Variability Threshold Were Produced, Covering Each Mandatory Characteriser. The Framework Was Developed Based On A Limited Set Of Information Covering Metallic And Carbon-Based Nanomaterials. The Present Contract Aims At Refining The Threshold Values Pre-Established And Validating It With Additional Data Sets, Covering A Wider Range Of Chemical Types. This ProjectS Outcome Is Expected To Become A Basis For Echa To Develop New Guidance For Registrants Of Nanoforms Of A Substance.
