Reaction Mass of Dialuminium Titanium Pentoxide and Strontium Calcium Aluminosilicate

Long-term toxicity to aquatic invertebrates

Link to relevant study record(s)

Reference

Endpoint:

long-term toxicity to aquatic invertebrates

Remarks:

In accordance with Column 2 of REACH Annex IX, the study does not need to be conducted as all identified uses of the substance are assessed as safe for the environment.

Data waiving:

Executive summary:

This reaction mass mixture of Dialuminum titanium pentaoxide (Al2TiO5), SrAl2Si2O8 (general CAS for Feldspar group), CaAl2Si2O8, and Residual Al2O3 is insoluble in water and has no known toxicity to fish or other aquatic invertebrate. The major constituent has been accepted as being non-toxic long term to fish within its REACH registration and the other constituents are naturally occurring substances. When the substance does dissolve its dissociated elements are very common ions already found in abundance within the soil and water.

Description of key information

In accordance with Column 2 of REACH Annex IX, the study does not need to be conducted as all identified uses of the substance are assessed as safe for the environment.

Additional information

This data point has been waived for dialuminium titanium pentaoxide on the grounds that the exposure potential in the aquatic environment is expected to be negligible. Under these circumstances, data for the long-term effects of dialuminium titanium pentaoxide on aquatic invertebrates are considered unnecessary.
