Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The following reliable data is available for environmental classification:

Acute Aquatic Toxicity:

Short-term toxicity to fish:

The 96 h LC50 (Danio rerio; mortality); 500 mg/l and the 96 h NOEC; >500 mg/l (method 84/449/EWG, C.1; OECD 203; 1984)

 

Short term toxicity to invertebrates:

The 48 h EC50 (immobilisation) to invertebrates; 750 mg/l and the 48 h NOEC; 100 mg/l (method 84/449/EWG, C.2)

 

Toxicity to algae:

The 72 h EC50 (Desmodesmus subspicatus;growth rate) at its maximum solubility (90 mg/l) did not cause inhibition - toxic effects, but there was observed the opposite effect – a stimulation of growth. No effective – inhibition concentrations could be calculated (OECD 201). EC50 value > 90 mg/l.

 

Conclusion: No acute aquatic toxicity as the lowest of the available toxicity value is > 100 mg/l.

Chronic aquatic toxicity:

Degradation:

Abiotic degradation (hydrolysis): Hydrolytically stable, Half-life over 8760 h at 50 deg.C.

Biotic degradation: biodegradation-% 35 after 28 d exposure (OECD Guideline 301 D). The substance is not considered as readily biodegradable.

Bioaccumulation:

Log Kow of the substance is 1.8442 (KOWWIN estimate; EPA 2013). Not bioaccumulative as log Kow < 4.

 

Conclusion: No chronic aquatic toxicity as the lowest available toxicity value is > 100 mg/l, substance is not readily degradable but has low bioaccumulation potential.

Environmental classification:

In accordance with EC Regulation 1272/2008 (CLP):

Not classified as hazardous

In accordance with DSD (Directive 67/548/EEC):

Not classified as hazardous
