Conclusion. In short, an EU-wide ban on the use of titanium dioxide could be put to a SCoPAFF Tox & NF vote in September 2021 and come into effect by January 2022 with a relatively short transition period of 6 to 9 months. We await the outcome of the UK FSA scrutiny of the EFSA assessment and expect no further national action in the …
