Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There is data on short-term aquatic toxicity for invertebrates as well as algae available. The toxicity of the source substances and magnesium salts towards different test organisms has been investigated.
Referring to toxicity towards aquatic invertebrates, data on Sodium gluconate(CAS 527-07-1) and different magnesiums salts has been used to assess the toxic behaviour of Magnesium glucoheptonate (CAS 1821694-26-1). The most critical effect concentration was found by Biesinger and Christensen (1972) in a study similar to OECD 202, who report an EC 50 (48 h) value of 16.7 mg Mg/L for Daphnia magna. This leads to a calculated EC50 (48 h) value of 273.77 mg/L for the target substance.
With regard to aquatic toxicity towards algae, data on Sodium gluconate (CAS 527-07-1), Gluconic acid (CAS 526-95-4) and magnesium salts is available. The most critical effect concentration was identified by OECD SIDS (2004). Using Desmodesmus subspicatusas test organism in a OECD 201 study, an EC50 (72 h) of > 100 mg/Land a NOEC (72 h) of 100 mg/Lwere determined for the substance Sodium gluconate (OECD SIDS, 2004).
Taking all aquatic toxicological data on source substances into account, Magnesium glucoheptonate (CAS 1821694 -26 -1) is assessed to have a very low toxicity potential. The substance is readily biodegradable and has effect concentrations well above 1 mg/L. Conclusively, no environmental classification is triggered by Regulation (EU) No. 1272/2008.
Additional information
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.
