Nalgene is the main product line of Nalge Nunc International, a distributor and manufacturer of plastic laboratory containers that has diversified into the field of containers for outdoor sports. In recent years, studies have suggested that polycarbonate plastics such as the ones Nalgene used may leach endocrine disruptors like Bisphenol A (BPA). Nalgene denies that the quantity leached from their products posed a significant threat to health, but as of April 2008 they began phasing out production of any BPA containing products. All current Nalgene water bottles are made from copolyester.
