EU to Identify 4-Tert-Butylphenol as a Substance of Very High Concern (SVHC)

On Feb. 7, 2019, the European Commission notified the WTO of its intention to identify 4-tert-butyl phenol (PTBP) as a substance of very high concern. The draft implementing decision states this is because of its endocrine disrupting properties and the probable severe effects of the substance to the environment. If approved, the decision shall be recommended to the European Chemicals Agency (ECHA).
