Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 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
Overall conclusion: EC50 > solubility limit in test medium

Key value for chemical safety assessment

Additional information

Based on reliable studies with Alcamizer5 and Aluminium-magnesium-zinc-carbonate-hydroxide, both analogue substances,

[carbonato(2-)]hexadecahydroxybis(aluminium)hexamagnesium is considered to have an EC50 > 100 mg/L (i.e. > its solubility limit in test medium).
