Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 fish:

OECD Guideline 203 (Fish, Acute Toxicity Test) 96h Rice fish - LC50 14.1 mg/L

OECD Guideline 203 (Fish, Acute Toxicity Test) 96h Rare Minnow fish - LC50: 1.78 mg/L (key study)

Long-term toxicity to fish: OECD Guideline 210 (Fish, Early-Life Stage Toxicity Test) (Key study)

NOEC (length & weight) = 1.25% stock solution (measured concentration 0.131 mg/L);

LOEC (length & weight) = 2.5% stock solution (measured concentration 0.426 mg/L).

Short-term toxicity to aquatic invertebrates: OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test)

48h Daphnia magna EC50 = 92.9 mg/L

Long-term toxicity to aquatic invertebrates: OECD Guideline 211 (Daphnia magna Reproduction Test)

Under valid semi-static test conditions (72h-renewal), for Daphnia magna reproduction the LOEC was 0.322 mg/L (measured TWA concentration) and the NOEC was 0.261 mg/L (measured TWA concentration). For survival of adults, the LOEC was 0.261 mg/L (measured TWA concentration), the NOEC was 0.186 mg/L (measured TWA concentration).

Toxicity to algae: OECD Guideline 201 (Alga, Growth Inhibition Test)

72-hour ErC50 = > 14.4 mg/L

NOECr = 4.24 mg/L

Toxicity to microorganisms: OECD Guideline 209 (Activated Sludge, Respiration Inhibition Test

30-minute EC50: >862 mg/L (analytical).
