Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The PNEC derivation was as follows justified:

PNEC freshwater sediment:

K_(susp-water) = 1.53

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_freshwater sediment

= (K_(susp-water) / RHO_(susp)) * PNEC_water * 1000

= (1.53/1150) * 0.1 * 1000

= 0.133 mg/kg wwt

= 0.612 mg/kg dw

 

PNEC marine water sediment:

K_(susp-water) = 1.53

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_marine water sediment

= (K_(susp-water) / RHO_(susp)) * PNEC_marine water * 1000

= (1.53/1150) * 0.01 * 1000

= 0.0133 mg/kg wwt

= 0.0612 mg/kg dw

 

PNEC soil:

K_(soil-water) = 0.953

RHO_(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

PNEC_soil

= (K_(soil-water) / RHO_(soil)) * PNEC_freshwater * 1000

= (0.953/1700) * 0.1 * 1000

= 0.056 mg/kg wwt

= 0.063 mg/kg dw

Conclusion on classification

Acute aquatic toxicity:

96 h, LC50 (Danio rerio): >100 mg/L (nominal concentration)

48 h, EC50 (Daphnia magna): >100 mg/L (nominal concentration)

72 h, ErC50 (Pseudokirchneriella subcapitata): >100 mg/L (nominal concentration)

Aquatic chronic toxicity:

72 h, ErC10 (Pseudokirchneriella subcapitata): >100 mg/L (nominal concentration)

Biodegradation: ultimately inherently biodegradable: 26 % after 28 days (% degradation O2 consumption, OECD 301D) and 55.4 % after 28 days (%DOC removal, OECD 301E)

Partition coefficient: component #1 log Kow = 0.73, component #2 log Kow = >-3.5, component #3 log Kow = >3.43 at 20 °C

Classification according to CLP

The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was found to be ultimately inherently biodegradable under the test conditions. In all aquatic tests the test item showed no toxic effect on the tested species. The determined EC50 and EC10 for Daphnia magna and green algae were >100 mg/L. The LC50 to zebrafish was determined to be >100 mg/L. Based on these results, the substance is neither classified for short-term (acute) aquatic toxicity nor classified for long-term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the twelfth time in Regulation (EU) 2019/521.
