What Are PFAS and Why Are They Important?
PFAS (per- and polyfluoroalkyl substances) are a group of synthetic chemicals widely used in textiles for their water and oil-repellent properties. However, due to growing concerns over their environmental persistence and potential health impacts, regulatory bodies worldwide have introduced stricter measures to control and eventually phase out their use.
Key Changes in PFAS Testing
The updated testing method incorporates alkaline hydrolysis, enabling the detection of PFAS compounds that were previously chemically bound to textiles and undetectable. This ensures your products meet the highest standards of compliance.
New Regulations and Deadlines
European Union:
- Expanded restrictions on PFOA (perfluorooctanoic acid) were introduced in September 2024.
- The use of undecafluorhexanoic acid (PFHxA) and related substances in consumer textiles, such as rain jackets, is now prohibited.
- A broader ban on PFAS is expected to be enacted in the coming years.
United States:
- From 1 January 2025, certain states will implement PFAS bans:
- California (Bill AB1817): Limits PFAS in garments to <100 ppm starting in 2025, reducing to xtagstartz50 ppm in 2027. For outdoor apparel designed for extreme wet conditions, an extension is granted until 2028.
- Products containing PFCs (perfluorinated compounds) must carry a label stating: "Made with PFC chemicals."
What Does This Mean for You?
- Fluorotelomer alcohols (C4 FTOH or higher): Textile finishing processes using these substances will no longer meet OEKO-TEX® requirements.
- PTFE Membranes: No longer permitted under STANDARD 100, except in the Supplement for Personal Protective Equipment (PPE).
Important: While the testing method has been updated, the limit values remain unchanged. Compliance depends on your materials and processes meeting these revised detection capabilities.
Practical Steps for Transitioning to PFAS-Free Compliance
Assess Your Supply Chain:
- Ensure your suppliers are STANDARD 100 certified and utilise ECO PASSPORT-certified chemicals. This provides confidence in the safety and compliance of your inputs.
Test Samples Before Renewal:
- Proactively send samples for individual PFAS tests before your next certification renewal. This gives you a clear understanding of your current compliance status.
Explore PFAS-Free Alternatives:
- Alternatives to PFAS often focus on a single functionality (e.g., water repellence or oil repellence). It is essential to prioritise which feature is most critical for your product's performance and select materials accordingly.
Documentation:
- Request certificates and test reports for all materials and retain delivery notes and invoices as proof of compliance.
Transition Period and Ongoing Support
Existing OEKO-TEX® certificates remain valid until their expiration. Testing under the updated method will apply to renewals, and previously compliant products may require adjustments to meet the new standards. To assist you during this transition, our team offers technical expertise and risk assessments tailored to your supply chain and product needs.
The Importance of Staying Informed
Not all customers will be affected by these changes, as not all products contain PFAS. However, staying informed about evolving regulations and best practices is essential. We encourage you to sign up for our newsletter to receive timely updates and expert insights on industry developments.
