Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Short-term toxicity to aquatic Invertebrates
Read-Across: WoE, FF6, OECD 202, GLP, D. magna, 48 h, EC50 = 4400 mg/L
Read-Across: WoE, Blancolen, OECD 202, GLP,D. magna, 48 h, EC50 = > 100 mg/L, NOEC = 100 mg/L
Read-Across: WoE, Zn ion, D. magna, 48 h, EC50 = 0.936 mg/L (converted to the target substance taking into account the Zn content of 14 % at the most)
Read-Across: WoE, Zn ion, D. magna, 48 h, EC50 = 2.53 mg/L (converted to the target substance taking into account the Zn content of 14 % at the most)
Toxicity to aquatic algae and cyanobacteria
Read-Across: WoE, FF6, D. subspicatus, OECD 201, GLP, 72 h, ErC50 = 315 mg/L
Read-Across: WoE, Zn ion, P. subcapitata, 72 h, ErC50 = 0.757 mg/L, 6.15 mg/L, 14.643 mg/L (values converted to the target substance considering the Zn content of 14 %)
Read-across: WoE, Zn ion, Chlorella sp., 72 h, ErC50 = 0.79 mg/L, ErC10 = 0.2 mg/L, LOEC = 0.31 mg/L, NOEC = 0.14 mg/L (values converted to the target substance considering the Zn content of 14 %)
Since the zinc concentration in TP 1740 is below 25 %, no classification for acute toxicity is required for the target substance in accordance with Regulation (EC) No 1272/2008.
Chronic toxicity
As in the case of acute toxicity, algae appear to be the most sensitive species with NOEC of 20 µg/L for Chlorella sp. (Johnson 2007). The maximum concentration of zinc ion in TP 1740 is 14 %. Since the zinc concentration in TP 1740 is below 25 %, classification for chronic toxicity category 2 is triggered for the target substance in accordance with Regulation (EC) 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.
