EU Sets 25 ppb PFHxA Limit for Cosmetics, Challenging Supply Chains

From 10 October 2026, the EU sets a 25 ppb concentration limit for PFHxA in cosmetics under Article 79 of REACH, according to the supplied event summary. With the restriction also covering trace impurities and related substances, cosmetics manufacturers and buyers face closer scrutiny of raw material traceability and testing.

Limits extend beyond intentionally added ingredients

The supplied information states that the 25 ppb limit applies to PFHxA, or perfluorohexanoic acid, and its salts in cosmetics, while related precursor substances are subject to a 1,000 ppb limit. It describes the restriction as covering not only intentionally added ingredients but also raw material impurities, residues and breakdown products. A product could therefore be unable to enter the EU market if relevant trace impurities exceed the stated limit, even when they are not apparent from its formulation.

Where trace contamination could affect supply decisions

Raw material sourcing and purchasing

From an industry perspective, buyers may need more information about substances present as impurities or residues, beyond the ingredients listed in a formulation. The ability to trace materials through the supply chain could affect how purchasing teams assess suppliers and investigate a potential exceedance.

Cosmetics development and manufacturing

Analysis suggests that OEM and ODM businesses may need to examine raw materials alongside finished formulations when assessing products intended for the EU market. If a trace substance is identified, determining its source and assessing whether an alternative material is suitable could affect development or production planning.

Testing and delivery

The low stated limits may make the suitability of testing methods and the clarity of reports particularly relevant to manufacturers and buyers. Depending on the results and the information available from suppliers, additional checks could affect delivery planning. The supplied information does not specify testing methods or documentation requirements.

Questions for procurement and compliance teams

Trace the materials behind the formula

Companies may wish to review the origin and available composition information for raw materials used in cosmetics intended for the EU market. Discussions with suppliers could focus on potential impurities, residues and breakdown products, as well as the information available to investigate their source.

Assess testing and supporting records

Businesses could evaluate whether available testing is suitable for assessing the stated limits and whether reports clearly identify the substances tested. Retaining relevant supplier information and test records may help teams review a product if questions arise; the input does not establish a specific recordkeeping requirement.

Review alternatives and delivery plans

Where a material raises questions, manufacturers and buyers could assess possible alternatives and verify their suitability before use. They may also consider how further checks could affect procurement and delivery schedules, while seeking clarification on applicable requirements.

Implementation details remain important

As an assessment based on the supplied summary, this is best understood as a stated rule taking effect on 10 October 2026, with practical execution still requiring verification. Further official information and market feedback could affect how businesses assess testing, documentation and supply decisions. No specific implementation guidance is provided in the input.

A traceability issue for EU-bound cosmetics

The stated limits make trace substances a relevant consideration alongside the declared formulation. For manufacturers and buyers, a measured response is to examine raw material information and testing capabilities while checking the applicable requirements and their implementation before making compliance decisions.
