Patent Alert 2026-05

This month's patent alert highlights recent innovations in PFAS-free technologies for textile materials. Per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals" due to their extreme persistence in the environment, are among the most concerning classes of contaminants found in a wide range of consumer and industrial products. As regulatory pressure and environmental concerns continue to increase, significant research efforts have been directed toward the development of safer and more sustainable alternatives. The patents selected below demonstrate strong innovation activity in silicon-based materials, wax-based technologies, polyurethane and methacrylate crosslinking systems, with a particular emphasis on bio-based raw materials as potential substitutes for PFAS in textile applications.
