Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Classification related information


Biodegradability: not readily biodegradable

Water solubility: <0.0352 mg/L

Log Pow: >4.19


Acute aquatic toxicity

Acute toxicity to Algae: 72-h ErC50 >0.1 mg/L, no effects up to limit of water solubility

Acute toxicity to Daphnia: 48-h EC50 >0.1 mg/L, no effects up to limit of water solubility

Acute toxicity to fish: 96-h LC50 >0.1 mg/L, no effects up to limit of water solubility


Chronic aquatic toxicity

Long-term toxicity to Algae: 72-h NOEC (growth rate) ≥ 0.1 mg/L, no effects up to the limit of water solubility

Long-term toxicity to Daphnia: 21-d EC10 >0.0052 mg/L (mean measured TWA), no effects up to limit of water solubility (OECD 211)


The available test data are reliable and suitable for classification purposes under Regulation 1272/2008 (CLP). The test item has a poor water solubility (<1 mg/L). No toxic effects were determined in acute and chronic aquatic toxicity tests up to the limit of the water solubility of the test item. No classification is required for Acute aquatic toxicity, as no effects were observed up to the limit of water solubility. Based on the low water solubility, the relatively high log Pow and the result of the biodegradation study, Fadex HE 1819 PK is therefore classified into aquatic chronic category 4 (H413: May cause long lasting harmful effects to aquatic life) according to Regulation (EC) No 1272/2008 (CLP) as amended for the eighteenth time in Regulation (EC) 2022/692.
