Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Aquatic environment classification

No data is available on the biodegradation of L-threonine mother liquor. Based on the composition of Biofert Plusz (mixture of L-threonine mother liquor and modified waste) it can be assumed that the results obtained with Biofert Plusz apply likewise to the test material under investigation (L-threonine mother liquor). Biofert Plusz proved to be readily biodegradable.

The lowest acute EC/LC50 value in aquatic tests is the EC50 of 148 mg dry matter/L based on geometric mean measured concentrations for the green algal species Desmodesmus subspicatus.

Due to its ready biodegradability and low log Pow (main component L-Threonine) the substance is not to be classified as dangerous/hazardous for the environment according to Directive 67/548/EEC and according to the Regulation (EC) 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP Regulation):

Lowest reliable L(EC)50 value:                 148 mg dry matter/L (algae)

Ready biodegradable                                yes

log Pow                                                 < 3 (main component)

Special concern:                                      no


According to 67/548/EEC Annex 1:      not classified


According to GHS:

Hazardous to the environment      not classified, no hazard statement

                                                      Reason for classification:    L(E)C50: > 100 mg/L; readily biodegradable, log Pow<4 (main component)

Hazardous to the atmospheric environment:

(Hazardous to the ozone layer: This includes substances which are listed in Annex I to Regulation (EC) No 2037/2000 of the European Parliament and of the Council of substances that deplete the ozone layer (1) and its subsequent amendments):
Biofert Plusz is not listed in Annex I of (EC) No 2037/2000.


M-Factor:                                       No

Labelling:                                        No Signal word and Pictogram for environmental hazards
