Summary

  • Industry is pushing back on blanket MWCNT classification, arguing that production method differences create meaningfully distinct toxicological profiles that demand substance-by-substance evaluation rather than group treatment.

The Japan Business Council in Europe (JBCE) has released a paper calling for an harmonized approach to the hazard classification of multi-wall carbon nanotubes (MWCNT), based on the latest information available on MWCNT effects and consistent with the classification of the International Agency for Research on Cancer (IARC).

The paper argues that the morphologies, physicochemical properties, and effects on the human organism of CNT depend on the different methods employed for their production, and that therefore different types of CNT should be evaluated separately depending on their characteristics rather than being grouped together.

OOECD Opens Public Consultation on Draft Test Guideline for Nanomaterial Solubility & Dissolution

The OECD has opened a public consultation on its draft Test Guideline for determining solubility and dissolution rates of nanomaterials in environmental fate assessments. The consultation runs until November 11, 2025. The draft guideline provides methods to measure apparent solubility over 24 hours and dissolution rates up to 72 hours across pH ranges of 5-8. The protocol consists of Part A (batch test for solubility) and Part B (time-resolved batch test for dissolution rate). The methods aim…

REACH Revision Presented at CARACAL-54 Includes Updates for Nanomaterials

At the meeting of the Competent Authorities for REACH and CLP (CARACAL) on 3-4 April, the European Commission presented to Member States their plans for the much-awaited REACH revision as part of the Commission's 2020 chemicals strategy for sustainability. This follows the announcement on 27th February on the adoption of the Chemical Package under the New Clean Industrial Deal. The update to the REACH regulation is expected in the final quarter of 2025. Currently an open Consultation is ongoing…
