environmentMost pin flame retardants have an environmentally friendly profile, which means that they pose no harm to the environment and do not bio-accumulate in biota. In addition they have a low (eco) toxicity profile and will eventually mineralize in nature. Due to these characteristics, none of the currently commercially used non-halogenated flame retardants are considered to be PBT or vPvB.

Manufacturers of flame retardants addressed data gaps and commissioned necessary tests and studies, because these are required by the European chemicals legislation, REACH (1907/2006/EC). Under REACH not only hazard data, but also data concerning emissions, uses and end of life are gathered. In the registration dossiers submitted to the European Chemicals Agency you find a wealth of detailed substance information, including summaries of toxicity and eco-toxicity tests (see http://echa.europa.eu/web/guest/information-on-chemicals/registered-substances). One company has also commissioned a life cycle emission study.

There have been various independent, third party evaluations of non halogenated flame retardants as part of environmental programmes initiated by authorities, agencies or NGOs. The majority of these studies specifically assess alternatives to major brominated flame retardants, such as the major research project ENFIRO which was sponsored by the European Commission (see reference below). These reports sometimes come to different conclusions on the same products, because of different criteria used and because not all authors had the same information available. In various studies the data generated by the manufacturers have not been included.
