For the past several months, Mayzo’s technical team has been assisting users find safe alternatives to UV-328 - (2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol) before a possible permanent ban is put into place in May of 2023. Mayzo provides specialty chemical additive solutions on a global scale in a wide range of markets. Currently, the company offers the following UV-absorbers.

In September 2022, the Persistent Organic Pollutants (POPs) Review Committee (POPRC) to the Stockholm Convention held its 18th annual meeting. During the meeting, the committee agreed to recommend listing the substance UV-328 (CAS 25973-55-1) under Annex A for global elimination of all production and use. A set of time limited exemptions were also recommended to allow some sectors – including aerospace and legacy vehicle parts – to phase out the chemical. The over 180 countries that are signatories to the Stockholm Convention will now meet in May 2023 to review the POPRC’s recommendation and finalize the listing.

UV-328 is used to absorb UV-light in a variety of plastics and coatings, including in food contact applications. The EU legally recognized UV-328 as a substance of very high concern (SVHC) in 2014, and it has been on the REACH Authorization list since 2019. UV-328 is unique in that it is the first substance to be proposed for listing under the convention that does not contain any halogens (fluorine, chlorine, or bromine).
