Additional information

The PNEC derivation was as follows justified:

PNEC freshwater sediment: 0.053 mg/L

K_(susp-water) = 3.15

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_freshwater sediment

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

= (3.15/1150) * 0.053 * 1000

= 0.145 mg/kg wwt

= 0.667853 mg/kg dw

PNEC marinewater sediment: 0.0053 mg/L

K_(susp-water) = 3.15

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_marinewater sediment

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

= (3.15/1150) * 0.0053 * 1000

= 0.015 mg/kg wwt

= 0.0667853 mg/kg dw

PNECsoil: mg/L

K_(soil-water) = 2.9

RHO_(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

PNEC_soil

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

= (2.9/1700) * 0.053 * 1000

= 0.0904 mg/kg wwt

= 0.10216 mg/kg dw

Conclusion on classification

Classification related key information


- Biodegradation: readily biodegradable: 100 % biodegradation after 14 days (EU Method C.4-B)


- Bioaccumulation: log Pow = 1.79 (OECD 117)


 


Aquatic acute toxicity


- Aquatic invertebrates: EC50 (48 h) = 75 mg/L (nominal, Daphnia magna, OECD 202)


- Algae: ErC50 (72 h) = 53 mg/L (nominal, Pseudokirchneriella subcapitata, OECD 201)


- Fish: LC50 (96 h) >60 mg/L (nominal, Danio rerio, OECD 203)


 


Aquatic chronic toxicity


- Algae: ErC10 (72 h) = 28 mg/L (nominal, Pseudokirchneriella subcapitata, OECD 201)


 


Classification, Labelling, and Packaging Regulation (EC) No 1272/2008


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 readily biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the toxicity test to algae (Pseudokirchneriella subcapitata). The test revealed a 72-hour ErC10 and ErC50 (growth rate) of 28 mg/L and 53 mg/L, respectively. The log Pow was determined to be 1.79. Based on these results, the substance is neither classified for aquatic acute toxicity, nor classified for aquatic chronic toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Commission Regulation (EU) 2020/1182.
