Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The chemical safety assessment according to Annex I of Regulation (EC) No. 1907/2006 does not indicate the need to further investigate the long-term toxicity to fish.
Key value for chemical safety assessment
Additional information
Experimental data on the long-term toxicity of Glycine are not available. However, the chemical safety assessment according to Annex I of Regulation (EC) No. 1907/2006 does not indicate the need to investigate further the long-term toxicity to aquatic organisms. Thus, in accordance to Annex IX, column 2 no further long-term toxicity test to fish is proposed.
Glycine is readily biodegradable; therefore it is not likely that aquatic organisms are exposed to the test substance since it will be ultimately degraded in sewage treatment plants. Glycine also has no potential to bioaccumulate. Furthermore, glycine did not show toxic effects on aquatic organisms at concentrations > 100 mg/L in acute aquatic toxicity tests. The amino acid is known to be a ubiquitous compound present mainly in protein molecules. Consequently, glycine is present in living organisms, in animal and vegetable foodstuff and in feed. Therefore, glycine is not expected to have any long-term toxic effects to aquatic organisms. This was confirmed in the toxictiy to Algae study where a NOEC ≥ 1000mg/L (the highest tested concentration) was observed. Therefore the chemical safety assessment does not indicate a need to investigate the further effects of Glycine on aquatic organisms, hence long-term toxicity testing with fish is considered as scientifically not necessary and unjustified.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
