Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The NOEC of quinic acid is >=  5000 mg/L for Daphnia magna during the test period of 48 h. Accompanying TOC-analysis resulted in mean measured concentrations of 133.6, 572.4 and 2211.0 mg/L in the lowest, middle and highest test concentrations. This corresponds to recovery rates of 97.8, 104.7 and 101.1%, indicating that the test item was stable during the test period of 48 h.

Additional information

Quinic acid was tested in a static Daphnia magna, Acute Immobilisation Test according to the OECD Guideline 202 for 48 h. Five nominal concentrations between 312.5 and 5000 mg/L were used. Daphnids did not show any adverse effects (including abnormal behaviour) in the controls and test concentrations. The NOEC of quinic acid is >= 5000 mg/L.

Further, in the study, published by Henschel, 1997 the EC50 of the read across substance salicylic acid for Daphnia magna was determined in fresh water for 48 h according to OECD Guideline. The EC50 of salicylic acid is 118 mg/l. In the publication of Sanderson 2009, the LC50 of the read across substance shikimic acid for Daphnia magna is given. The LC50 of shikimic acid is 116 mg/L.
