The EC is working on a detailed Q&A document to help interpret the October 2023 Commission Regulation (EU) 2023/2055 on microplastics restriction to help with implementation of the new rules. In the meantime, they published the current thinking on the application of the microplastics restriction, including glitter on its own and in products. 

European Chemicals Agency (ECHA)

Key Areas of Regulatory Challenge Report

Investigation Reveals Regulatory Action Needed to Mitigate Risks from PVC Additives and Microparticle Releases

The human health and environmental impact of 63 PVC additives, including plasticizers, heat stabilizers and flame retardants, was investigated in the “Investigation Report on PVC and PVC Additives.”

European Food Safety Authority (EFSA)

Guidance on Protocol Development for EFSA Generic Scientific Assessments

EFSA has released “Guidance on protocol development for EFSA generic scientific assessments” to provide a harmonized and flexible framework for protocols for generic assessments. The guidance is accompanied by a standalone “template” that guides users step by step through the process of planning an EFSA scientific assessment.

Government of Canada Seeking Input on Development of Strategy to Guide the 3Rs of Vertebrate Animal Testing

ECCC and HC published a notice of intent to develop a strategy to guide the replacement, reduction or refinement (3Rs) of vertebrate animal testing under the Canadian Environmental Protection Act. They are seeking input on the strategy. The 60-day comment period closes 29 January.

Draft Assessment for the Titanium-Containing Substances Group Published for Comment

The draft assessment for the 13 titanium-containing substances group concluded that the substances entering the environment do not have the potential for immediate or long-term harmful effect and thus do not meet any of the criteria set out in section 64 of the Canadian Environmental Protection Act (CEPA).

Assessments of Siloxanes Group and Gas Oils and Kerosenes

Final assessments of these compounds were published. Down from 7 siloxanes initially identified, 5 siloxane substances were identified for action under the Chemicals Management Plan (CMP) and assessed in the published document.

USEPA Prioritizes Five Chemicals Under the Toxic Substances Control Act (TSCA)

USEPA plans to prioritize the following chemicals for risk evaluation under TSCA: Acetaldehyde, Acrylonitrile, Benzenamine, 4,4’-Methylene bis(2-chloroaniline) (MBOCA) and Vinyl Chloride (CASRN 75-01-4).

USEPA Proposes to Strengthen Process for Conducting Risk Evaluations on Chemicals Under TSCA

The proposed rule includes changes to improve USEPA’s process for TSCA risk evaluations, such as commitment to consideration of the disproportionate harms facing overburdened communities, inclusion of all exposure pathways, and clarifications and assurances related to procedural requirements.

Ministry of Ecology and Environment (MEE), China

China MEE Published a Reference List of 363 Substances Related to PFOA

This list of the PFOA-related chemicals contains CAS numbers and identifiers to support the phase out of PFOA, its salts, and PFOA-related compounds. It is an update to the October 2023 inventory of severely restricted toxic chemicals.
