EU proposes to include TBPH in POPs regulations

The EU proposes to include TBPH (bis (2-ethylhexyl) tetrabromophthalate) in the POPs regulations.
About TBPH
TBPH is a brominated aromatic substance mainly used as a non reactive flame retardant additive. TBPH consists of three stereoisomers: two enantiomers (R, R and S, S) and a racemic isomer (R, S), which differ only in the spatial geometry of their structures. These three isomers exhibit similar behaviors during use and degradation, and may all possess similar properties of persistence, bioaccumulation, adverse effects, and long-distance migration.
TBPH and polybrominated diphenyl ethers (PBDEs) have similar structural characteristics, such as aromatic rings and bromination. According to the Stockholm Convention, some PBDEs have been gradually phased out globally as persistent organic pollutants (POPs) due to their persistence, bioaccumulation, and toxicity. These structural similarities have raised concerns that TPBH may cause environmental issues similar to PBDEs.
TBPH is a novel brominated flame retardant (NBFR) that was first commercially used between 1987 and 1994. TBPH has been sold as a substitute for PBDEs flame retardants, such as pentabromodiphenyl ether (pentaBDE) and octabromodiphenyl ether (octaBDE). TBPH can also be used alone or mixed with benzoic acid and 2-ethylhexyl-tetrabromobenzoic acid (TBB). The uses of TBPH include flexible polyvinyl chloride (PVC) for wire and cable insulation, rigid polyurethane (PUR) in the construction industry, and flexible PUR in interior decoration applications.
According to the REACH regulation, TBPH has been identified as a highly concerned substance (SVHC) in the European Union due to its high persistence and high bioaccumulation (vPvB) characteristics, and was included in the candidate list in November 2022. TBPH is part of a group of aromatic brominated flame retardants, and in 2024, ECHA evaluated potential restriction proposals for TBPH under REACH.
POPs regulations
Persistent Organic Pollutants (POPs) are a class of natural or synthetic organic pollutants that have long-term residues, bioaccumulation, semi volatility, and high toxicity, and can migrate over long distances through various environmental media (atmosphere, water, organisms, etc.), posing serious hazards to human health and the environment.
The main purpose of POPs regulations is to protect human health and the environment from the hazards of POPs, by reducing their production, use, and emissions, lowering their concentrations in the environment, and thereby reducing potential threats to ecosystems and humans. The regulations also require proper management and disposal of waste containing POPs to prevent secondary pollution to the environment.
Jiayu Testing Reminder
In recent years, the EU's POPs regulations have been updated frequently and enforcement efforts have been continuously strengthened. There have also been more and more cases of Chinese products being reported for violating POPs regulations when exporting to the EU. Enterprises should pay timely attention to regulatory developments, respond to adjustment strategies, ensure that products comply with new regulatory requirements, and reduce the risk of violations.
