Cefic Amines Sector Group Challenges ECHA Response On Diethanolamine (DEA) CLP Classification

In April 2026 Cefic’s Amines Sector Group formally challenged ECHA’s response to the RAC opinion classifying diethanolamine (DEA) as Carc. 2 and Repr. 1B under the CLP Regulation, arguing that rodent-based choline depletion mechanisms are not relevant to humans. This challenge does not itself change obligations but could still influence the final harmonised classification and resulting labelling and risk management duties for DEA-containing products, so companies using DEA should monitor the 25th ATP outcome and plan for both stricter and more lenient classifications.

Austria Supports RAC Opinion on Diethanolamine Classification Under 25th CLP ATP

Austria’s competent authority has formally backed the ECHA Committee for Risk Assessment proposal to classify diethanolamine (2,2'-iminodiethanol) as a carcinogen category 2 and reproductive toxicant category 1B, alongside existing acute and repeated-dose toxicity classifications, under the planned 25th adaptation to technical progress of the EU CLP Regulation. This non-binding but authoritative support makes it more likely that a stringent CMR classification for DEA will be retained in the final CLP ATP, so EU manufacturers and downstream users should prepare for tighter labelling, risk management and potential knock-on regulatory impacts once the amendment is adopted and in force.

ECHA Assessment of Regulatory Needs for 2,6-di-tert-butyl-p-cresol (BHT)

ECHA has issued a group Assessment of Regulatory Needs (ARN) for tert‑alkyl hindered phenols and created a dedicated ARN entry for 2,6‑di‑tert‑butyl‑p‑cresol (BHT), identifying it as part of a priority group with potential endocrine‑disrupting, reproductive and PBT/PMT concerns and widespread uses as an antioxidant in fuels, lubricants, plastics, coatings, adhesives and cosmetics. While no binding measure has yet been proposed, ECHA explicitly foresees harmonised classification followed by a REACH restriction if the hazards are confirmed, so companies using BHT at scale should monitor this file closely and consider substitution or risk‑reduction options in affected formulations and articles.

Global Scientific Review Links Chemicals And Climate Change To Fertility Declines

An April 2026 Nature review concludes that PFAS, microplastics, pesticides and other endocrine-disrupting chemicals, together with climate change, are measurably reducing fertility and fecundity across humans and wildlife. This cross-species evidence is likely to strengthen demands for class-based regulation of hazardous chemicals, shape the design of a global plastics treaty, and raise expectations for tighter reproductive-health and biodiversity protections over the coming decade.

ECHA Enters Follow-Up Stage on REACH Testing Proposal for 1,1'-[oxybis(ethyleneoxy)]diethylene

In late April 2026, ECHA moved its REACH testing proposal for 1,1'-[oxybis(ethyleneoxy)]diethylene into the follow-up phase, after the 27 April 2026 deadline for registrants to submit new 90-day repeated-dose and pre-natal developmental toxicity studies and update their dossiers. This shift means ECHA is now checking compliance with the 2023 testing decision and may involve national enforcement authorities where data are missing, increasing regulatory and enforcement risk for EU-based registrants using this substance.
