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
Additional information
Three aquatic toxicity studies have been conducted according to GLP and OECD guidelines, these studies have been conducted on Oncorhynchus mykiss (rainbow trout), Daphnia magna (water flea) and Pseudokirchneriella subcapitata (green algae).
The results of the three short term aquatic tox studies were as follows:
Fish LC50 = > 1000 mg/L Fish NOEC = 1000 mg/L
Daphnia EC50 = > 1000 mg/L Daphnia NOEC = 1000 mg/L
Algae EC50 = 790 mg/L Algae NOEC = 100 mg/L
An ASRI study was also conducted on the test material, the EC50 value was greater than 1000 mg/L and the NOEC was determined to be 1000 mg/L as no effects were observed within the study. Due to this the ASRI study is not classified.
From the results of these three studies it can be seen that the algae is the most sensitive species to the test material. The algae study produced the lowest EC50 value out of all three aquatic toxicity studies, and all three studies were tested up to the same concentration level (1000 mg/L). The results of this study were not sufficient to warrant classification as the test material is readily biodegradable in water. Therefore the test material sodium glucoheptonate has not been classified as hazardous to the environment.
Please note that the aquatic toxicity studies will be used for other notifications, hence why concentartions higher than the normal guidelines have been used within these studies.
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.
