company says is based on Clariant’s proprietary organic materials, is available in Asia-Pacific and greater China. Other new products will be launched in 2025 for EMEA and the Americas. Dover Chemical announced that the European
Food Safety Agency (EFSA) has published a safety assessment endorsing its antioxidant Doverphos LGP-12 (liquid green phosphite) for EU food contact. The company says that the antioxidant has a cleaner toxicology profile than traditional phosphite stabilisers and has been designed with “future compliance” in mind, as regulatory bodies increase scrutiny of human health effects from additives and their degradation products. The additive is a high molecular weight polymeric phosphite and its high phosphorus content allows it to be used at lower loading levels, both of which contribute to low migration. The additive received US FDA clearance for food contact in LLDPE in 2019 and for HDPE in 2023. The company reports that it has submitted requests for food-contact approval from other major global regulatory bodies. LGP-12 also acts as a PFAS-free and silicone-free polymer processing aid (PPA), showing both the ability to clear melt fracture in blown film and to

reduce die-lip buildup in cast film. PPAs from Dover Chemical available in masterbatch form with an LLDPE carrier include Doverclear 840 for resins with a melt index greater than one, and Doverclear 841 for resins with fractional melt indices. The PPAs are typically used at 0.5-2.5% in the final product, and they are also available in other carrier resins.
