Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PNEC freshwater sediment:

K (susp-water) = 191 m3/m3

RHO (susp) = 1150 kg/m3

Conversion factor (wwt -> dwt): 4.6  

PNEC (freshwater sediment) = (K (susp-water)/ RHO (susp))*PNEC (water) * 1000

= (191/1150)* 0.1 mg/L * 1000

= 16.6 mg/kg wwt

= 76.36 mg/kg dwt  

 

PNEC marine water sediment:

K (susp-water) = 191 m3/m3

RHO (susp) = 1150 kg/m3

Conversion factor (wwt -> dwt): 4.6  

PNEC (marine water sediment) = (K (susp-water)/ RHO (susp))*PNEC (marine water) * 1000

= (191/1150)* 0.01 mg/L * 1000

= 1.66 mg/kg wwt

= 7.636 mg/kg dwt 

 

PNEC soil:

K (soil-water) = 228 m3/m3

RHO (soil) = 1700 kg/m3

Conversion factor (wwt -> dwt): 1.13  

PNEC (soil) = (K (soil-water)/ RHO (soil))*PNEC (water) * 1000

= (228/1700)* 0.1 * 1000

= 13.41 mg/kg wwt

= 15.15 mg/kg dwt

Conclusion on classification

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, as amended for the twelfth time in Regulation (EU) 2019/521.


Acute aquatic toxicity:

Based on the results obtained, substance HAT-ISO is not classified or labelled for acute aquatic toxicity, according to Regulation (EC) No 1272/2008 (CLP) as all acute LC/EC50 values were well above 100 mg/L.

Chronic toxicity:

Based on the study results (no toxicity up to 100 mg/L, not readily biodegradable, very low water solubility and high Log Pow) the substance is classified as aquatic chronic cat. 4 (H413) according to Regulation (EC) No 1272/2008.
