Experimental approaches to data generation for REACH compliance of multi-walled carbon nanotubes: substance identification

Key Points

• The research aims to evaluate standardized testing guidelines for multi-walled carbon nanotubes and to propose a new characterization method.
• Evaluated existing guidelines for size, shape, and dustiness testing of MWCNTs.
• Developed a non-invasive method for characterizing length of carbon nanotubes.
• Assessed the feasibility of the new method for regulatory risk assessment.
• Identified gaps in existing testing guidelines for MWCNTs.
• Proposed a novel method that offers more accurate representations of nanotube characteristics.
• Demonstrated that the non-invasive method could enhance regulatory compliance assessments.
