Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Read-across from analogue substances Alcamizer 5 (EC no: 422-150-1) and Alcamizer P93 (EC no: 423-570-6): no visible acute effects in Daphnia magna at the highest loading rate tested, i.e. 100 mg/L. Therefore, the 48-h EC50 is concluded to be > solubility limit in test medium.
Overall conclusion: EC50 > solubility limit in test medium
Key value for chemical safety assessment
Additional information
Read-across from Aluminium-magnesium-zinc-carbonate-hydroxide (EC 423-570-6):
Under the conditions of the test (OECD 202, static, according to GLP), Aluminium-magnesium-zinc-carbonate-hydroxide-(hydrate) induced no effects in Daphnia magna exposed to a nominal loading rate of 100 mg/L. Hence, the 48-hour EC50 was > 100 mg/L (> water solubility, > solubility limit in test medium), the highest loading rate tested.
Read-across from Alcamizer 5 (EC 422-150-1):
EC50 for freshwater invertebrates (OECD 202 and GLP guidelines): > 100 mg/L (loading rate), i.e. > solubility limit in test medium
Conclusion:
Based on reliable studies with the analogue substances Alcamizer 5 and Aluminium-magnesium-zinc-carbonate-hydroxide, Aluminium magnesium carbonate hydroxide is considered to have an EC50 > 100 mg/L (loading rate, thus 48 -h EC50 > solubility limit in test medium).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
