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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 fish
The LC50 of the test item was determined to be 1020 mg/L.
Short-term toxicity to aquatic invertebrates
A 48-hour EC50 value of 74 mg/L (based on the measured time weighted average concentration) was found in a valid semi-static study on the acute toxicity of the substance to Daphnia magna.
Toxicity to aquatic algae
The test item sodium ascorbate had no statistically significant inhibitory effect on the growth of the algae (average growth-rate and yield) at the highest tested concentration of mean measured 74 mg/L. On the basis of the mean measured concentration of the test item, the 72-hour EC50 was determined to be > 74 mg/L for the growth rate and yield, respectively; the 72-hour NOEC was determined to be ≥ 74 mg/L both for the growth rate and yield.
Toxicity to microorganisms
The study does not need to be conducted because in the toxicity control of the ready biodegradability test (see IUCLID section 5.2.1), the test item was not inhibitory to activated sludge at the tested concentration of 80 mg/L. Thus, further testing on toxicity to microorganisms is scientifically not necessary.
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.
