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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Acute toxicity
Short-term toxicity to fish
Key study: OECD 203, GLP, semi-static, Danio rerio, LC50 (96h) > 100 mg/L
Read-Across: WoE, FF6, OECD 203, GLP, static, Danio rerio, LC50 (96h) >7400 mg/L
Read-Across: WoE, Zn ion, Cottus bairdi, 96 h, LC50 = 2.66 mg/L(converted to the target substance taking into account the Zn content of 16.5 %)
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 = 0.79 mg/L (converted to the target substance taking into account the Zn content of 16.5 %)
Read-Across: WoE, Zn ion, D. magna, 48 h, EC50 = 2.15 mg/L (converted to the target substance taking into account the Zn content of 16.5 %)
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, P. subcapitata, 72 h, ErC50 = 0.64 mg/L - 12.42 mg/L (values converted to the target substance considering the Zn content of 16.5 %)
Read-Across: WoE, Zn, Chlorella sp., 72 h, ErC50 = 0.55 mg/L, ErC10 = 0.17 mg/L, LOEC = 0.27 mg/L, NOEC = 0.12 mg/L (values converted to the target substance considering the Zn content of 16.5 %)
Conclusion
Since the zinc concentration in the registered substance is below 25 %, no classification for acute toxicity is required for the target substance in accordance with Regulation (EC) No 1272/2008.
Chronic toxicity
Long-term toxicity to fish
Read-Across: WoE, Zn ion,O. mykiss, 30 d LC50: 2.04 to 11.94 mg/L; NOEC (30 d): 1.26 to 4.67 mg/L(converted to the target substance taking into account the Zn content of 16.5 %)
Read-Across: WoE, Zn ion,O. mykiss, MATC obtained in hard water of 1.94 - 3.88 mg/L and a MATC obtained in soft water of 0.85 - 1.58 mg/L(converted to the target substance taking into account the Zn content of 16.5 %)
Long-term toxicity to aquatic invertebrates
Read-Across: WoE, Zn ion,D. magna, 21 d, EC50: 0.68 to 3.25 mg/L, NOEC: 0.38 - 2.98 mg/L (converted to the target substance taking into account the Zn content of 16.5 % at the most)
Read-Across: WoE, Zn ion,C. dubia, 9 d, EC 50: 2.15 - 2.96 mg/L (converted to the target substance taking into account the Zn content of 16.5 % at the most)
Conclusion
As in the case of long-term/chronic toxicity, algae appear to be the most sensitive species with NOEC of 0.12 mg/L for Chlorella sp. (Johnson 2007). The maximum concentration of zinc ion in the registered substance is 16.5 %. Since the zinc concentration this is below 25 %, classification for chronic toxicity category 2 is triggered for the registered substance in accordance with Regulation (EC) No 1272/2008.
Toxicity to microorganisms
Read-across : WoE, FF6, OECD 209, GLP, activated sludge, EC50 (3h) > 2000 mg/L, NOEC (3h) < 125 mg/L
Read-Across: WoE, Zn ion, ISO 9509, activated sludge, 3 h, IC50 = 13.39 mg/L (converted to the target substance taking into account the Zn content of 16.5 %), NOEC = 3.82 mg/L (converted to the target substance taking into account the Zn content of 16.5 %)
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.
