The European Chemicals Agency (ECHA) has published an assessment identifying potential hazards and regulatory gaps for a group of chemicals known as aliphatic amines with ether substituents. Released on 4 November 2024, the report underscores the need for harmonised classification and targeted regulatory actions to mitigate risks associated with these substances in industrial, professional, and consumer applications.
Overview of Aliphatic Amines with Ether Substituents
Aliphatic amines with ether substituents encompass 33 substances, primarily defined as mono-constituent chemicals with variations in carbon chain lengths and structural features. Their uses span across cosmetics, adhesives, coatings, and industrial applications such as mining and gas treatment. The report highlights their significant exposure potential, particularly in products like lubricants and cleaning agents used by professionals and consumers.
Identified Hazards and Data Gaps
ECHA has identified multiple concerns, including reproductive toxicity (category 1B), skin sensitisation, specific target organ toxicity (STOT), and aquatic toxicity. Specific substances such as 3-methoxypropylamine (EC 226-241-3) and 3-(tridecyloxy)propylamine (EC 931-295-2) are flagged for high exposure potential and environmental risks. Some compounds, like those used in closed industrial systems, have lower exposure risks but still require additional scrutiny for potential hazards such as persistence and bioaccumulation.
Proposed Regulatory Actions
The report proposes several steps to address these risks:
- Harmonised Classification and Labelling (CLH): This is prioritised to confirm reproductive toxicity and other hazards, laying the groundwork for restrictions under the REACH regulation.
- Data Generation: Additional studies, including aquatic toxicity and long-term environmental impacts, are suggested for specific substances.
- Restrictions: Consumer and professional uses may face limitations if hazards are confirmed, particularly for substances in cosmetics and textile dyes.
Implications for Industry
ECHA emphasises the importance of this assessment for industries to align with future regulatory changes. Companies are advised to monitor developments and reassess their chemical portfolios to anticipate potential restrictions.
The ECHA report marks a critical step in addressing chemical safety concerns associated with aliphatic amines with ether substituents. Its findings could lead to significant regulatory actions, impacting industries and ensuring enhanced protection for human health and the environment.
