Guided by our sustainability roadmap Solvay One Planet, the development of our new non-fluorosurfactant technologies (Hylar® 5000S and Tecnoflon® LX) is an example of our innovation at work. These technologies use a new polymerization process that does not require the use of PFAS-based process aids, while keeping important properties required by customers and applications. With these technologies now in full production at our West Deptford, New Jersey facility, Solvay has eliminated the use of fluorosurfactant process aids in the U.S.

Innovating with non-fluorosurfactant technologies

Picto research and development

Since 2019, we quadrupled our investment in R&D and mobilized a task force of nearly 100 professionals to develop non-fluorosurfactant technologies to meet the performance needs of our customers in a more sustainable way.

Our goal is to use non-fluorosurfactant technologies, wherever possible. To achieve this goal, we pursue new technological innovations that advance our sustainability ambitions. Research is ongoing to transform our products and provide more specialized products that our customers can qualify for use in a variety of applications that support a more sustainable society and green mobility, This includes solutions used in renewable energy installations, lithium-ion batteries, and components for compact engines in hybrid vehicles.



While phase out of PFAS-based process aids is not yet feasible in all locations or applications, Solvay is introducing state-of-the-art technologies with the objective to eliminate fluorosurfactant emissions from its manufacturing. This is a concrete example of how we are using science to focus on a more sustainable future.

Our ambition

  • Our success in developing non-fluorosurfactant technologies in West Deptford was the first step in our journey. It remains our ambition to phase out the use of PFAS-based process aids in Spinetta, Italy. 
  • The products we make in Spinetta are being reformulated using a second generation fluorosurfactant process aid (C6O4).
  • C6O4 is neither biopersistent nor bioaccumulative, is registered in accordance with REACH (the European Union's regulation for the Registration, Evaluation, Authorization and Restriction of Chemicals) and has been approved by the EFSA (European Food Safety Authority).
  • In addition, for our manufacturing in Spinetta,Solvay applies state-of-the-art techniques that eliminate nearly 100% of fluorosurfactant emissions.

Quick facts on Solvay and PFAS


Solvay has never manufactured or sold PFOA- or PFNA-based process aids.


Solvay never used PFOS or manufactured firefighting foams—a key source of certain PFAS in the environment.


Solvay voluntarily phased out use of PFOA- and PFNA-based process aids in the U.S. in 2003 and 2010, respectively, and phased out use of PFOA-based process aids globally in 2013.
