EU scientists find evidence of BPA in non-polycarbonate baby bottles

The European Commission Joint Research Centre (JRC) has published the final results from a monitoring study on the release of chemical substances from plastic baby bottles, which found that bisphenol A (BPA) was present in one product made of polyamide.

Researchers measured the migration of chemicals from 277 baby bottles purchased throughout Europe and the US. The bottles were made of alternative non-polycarbonate materials including polyamide, polyethersulphone, polypropylene and silicone, used since the ban on plastics containing BPA entered into force on 1 March 2011.

The results indicate that in general there is a low release of chemicals from all bottles, supporting preliminary results. However, BPA was detected in one polyamide bottle labelled ‘BPA free’. Bottles made of polypropylene and silicone were also found to release several chemicals that are not included on the positive list and therefore not permitted for use in such products, including phthalates.

The researchers conclude these results should be taken into account in future risk assessment of plastic baby bottles, and recommend intensifying testing of substitute plastics now in use by official food control laboratories to inform risk management efforts.

A representative from PlasticsEurope, commenting on the chemicals measured in polypropylene bottles, said, “Some of the substances found are degradation products of anti-oxidants, which are well-known, well tested and are on the EU list of substances, which is part of the EU regulation governing plastics in contact with food. This regulation allows the use of non-intentional substances such as impurities and degradation products, provided industry can demonstrate their safety. Our industry is in regular contact with the additive producers who in turn provide input on the safety of the additives and their reaction products.”

In response to the detection of BPA in polyamide, the industry group, World Association of Manufacturers of Bottles and Teats (WBT), says “We are currently in the process of working with raw material industry experts and authorities to qualify and monitor alternative plastic materials for baby bottles, and to understand the results found for some polyamide baby bottles. Until such a process is complete, we are not in a position to comment any further on this report.”
