ADDITIVES | ANTIOXIDANTS AND STABILISERS
as substances of concern under regulatory criteria. However, exactly these properties are inherent to, and necessary for, their effectiveness and perfor- mance as UV stabilisers. As a result, any substitution would likely require substances with similar intrinsic properties. A ban on this group of substances could leave industry without viable alternatives in Europe, potentially leading to the relocation of manufactur- ing activities outside the EU.” The group suggested that “other risk manage-
ment measures are available to effectively control emissions and exposure to these substances.”

Chair of the Technical Committee and Director, Application Technology at Rianlon. The group plans to establish three task forces covering key additive families used in plastics, coat- ings, adhesives, rubber and other polymer applica- tions. The task forces will provide a coordinated platform to organise data, engage stakeholders, and support science-based regulatory decisions, the group said. At the end of July, GALA members provided comments to the European Chemicals Agency (ECHA) as part of the public consultation on the draft recommendation to include UV-326 and UV-329 as priority substances in Annex XIV of the REACH Regulation. The hydroxyphenyl benzotriazole UV additives were included in a list of candidates for possible restriction in 2024 based on their assess- ment as very persistent and very bioaccumulative. GALA stated that “the intrinsic properties of
certain UV stabilisers may lead to their identification
Growing outdoor use BASF announced in April that it was expanding capacity for standard hindered amine light stabilis- ers (HALS) and NOR HALS to meet growing global demand. BASF now also offers its NOR HALS in an attrition-resistant product form that reduces dust during handling and processing of the additive and simplifies masterbatch production. Agricultural films – including greenhouse, mulch,
tunnel, silage, and bale wrap – are one area where NOR HALS technology helps resist high UV exposure, elevated temperatures, sulphur-based products that create acidic microclimates, and increasingly harsh pesticides, the company said. “This robust stabilisation enables enhanced
structural and optical integrity for reliable multi- season performance, reducing replacement frequency, labour effort, and waste,” BASF said. Maintaining optical clarity and structural integrity is particularly important in greenhouse films, where it is needed to ensure consistent light transmission to help maximise yields. Longer-lasting film means less frequent replacement, fewer breakages and
