German CA Urges More Self‑Reactivity Testing For Hydrogen Peroxide Below 42.5% In CLP 25th ATP Process

In May 2026, the German Competent Authority for REACH and CLP endorsed RAC’s proposed oxidising classification thresholds for hydrogen peroxide in the planned 25th ATP to CLP but warned that self-reactive properties may remain relevant for solutions below 42.5%, especially in biocidal products. This signals that EU assessors may increasingly expect additional self-reactivity testing and physical-hazard justification for hydrogen peroxide formulations below current harmonised thresholds, raising future compliance and testing burdens for biocide and other mixture manufacturers.

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.

EUROTALC Requests RAC Reassessment of Talc Classification Under REACH

In April 2026, EUROTALC submitted a detailed letter to CARACAL urging the ECHA Risk Assessment Committee to reassess its proposed harmonised classification of talc, based on a newly published quantitative bias analysis showing recall bias likely explains observed associations between genital talc use and ovarian cancer. If regulators accept this analysis and reopen the weight-of-evidence review under Article 77(3)(c) REACH, the final EU classification outcome for talc—and therefore labelling, use conditions and potential restrictions across cosmetics and other applications—could change materially, so companies relying on talc should closely monitor the process.
