Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Short-term toxicity to fish: TLm (48h) > 1000 mg/l

Short-term toxitiy invertebrates: EC50 (48h) > 100 mg/l (nominal)

Toxicity to aquatic plants other than algae: ErC50 (frond number, dry weight) > 100 mg/l (A.I., nominal)

Additional information

The toxicity potential of the substance to aquatic invertebrates and to aquatic plants other than algae was evaluated and the following results were obtained:

Fish: TLm (48h) > 1000 mg/l

Daphnia: EC50 (48h) > 100mg/l (nominal).

Lemna: ErC50 (frond number, dry weight) > 100 mg/l (A.I., nominal) and NOErC (frond number, dry weight) = 100 mg/l (A.I., nominal).

Justification for classification or non classification

According to the table 4.1.0 of the CLP Regulation (EC) No. 1272/2008, a substance shall be classified as Aquatic Category Acute 1 when:

96 hr LC50 (for fish) < 1 mg/l and/or

48 hr EC50 (for crustacea) < 1 mg/l and/or

72 or 96 hr ErC (for algae or other aquatic plants) < 1 mg/l.

 

Moreover, substance for wich adequate chronic toxicity data are not available shall be classified as:

- Aquatic Chronic 1 when:

96 hr LC50 (for fish) < 1 mg/l and/or

48 hr EC50 (for crustacea) < 1 mg/l and/or

72 or 96 hr ErC (for algae or other aquatic plants) < 1 mg/l

 and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log K ow ≥ 4)

- Aquatic Chronic 2 when:

96 hr LC50 (for fish)>1 to10 mg/l and/or

48 hr EC50 (for crustacea)>1 to10 mg/land/or

72 or 96 hr ErC (for algae or other aquatic plants)>1 to10 mg/l

and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log K ow ≥ 4)

- Aquatic Chronic 3 when:

96 hr LC50 (for fish)>10 to100 mg/l and/or

48 hr EC50 (for crustacea)>10 to100 mg/land/or

72 or 96 hr ErC (for algae or other aquatic plants)>10 to100 mg/l

and the substance is not rapidly degradable and/or the experimentally determined BCF ≥ 500 (or, if absent, the log K ow ≥ 4)

 

The substance is not readily biodegradable and the effective levels for both aquatic invertebrates and aquatic plants is higher than 100 mg/l. A classification for aquatic toxicity (acute or chronic) according to the CLP Regulation (EC) No.1272/2008, is not proposed.
