The reclassification of TPO (Diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide, CAS n. 75980-60-8) is a significant change within the energy curing industry, as it directly impacts product formulation, regulatory compliance, and market dynamics.  

TPO has been reclassified as Reproductive Toxicity Category 1B and was added to the EU REACH Candidate List for Authorization as a Substance of Very High Concern (SVHC) on June 14, 2023. This classification is based on its reprotoxic properties under Article 57(c). In response, iGM Resins has updated the EU Safety Data Sheets (SDS) to reflect this change.

While some industry members may express concerns about reclassification of TPO, these issues must be weighed against the long-term benefits of regulatory alignment with health and environmental goals.  

At iGM Resins, we prioritize the safety of chemicals. Our dedicated team of experts works diligently to ensure that our products comply with regional and international legislation, promoting safer usage across all applications.  

This commitment reflects our responsibility to our customers, the environment, and the future of the energy curing industry.
