Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 aqua: The PNEC aqua was derived on the basis of the lowest acute toxicity test (LC50 or EC50) for all 3 trophic levels (fish, daphnia , algae) and applying an assessment factor of 1000. The PNEC aqua is based on the test for acute toxicity in fish : PNEC aqua = 0.87 mg/l/ 1000 = 0.00087 mg/l

PNEC marine aqua: The PNEC marine aqua was derived on the basis of the lowest acute toxicity test (LC50 or EC50) for all 3 trophic levels (fish, daphnia , algae) and applying an assessment factor of 10,000. The PNEC aqua base on the test for acute toxicity in fish : PNEC aqua = 0.87 mg/l/ 10000 = 0.000087 mg/l

PNEC aqua intermittent: The PNEC aqua intermittent was derived on the basis of the lowest acute toxicity test (LC50 or EC50) for all 3 trophic levels (fish, daphnia , algae) and applying an assessment factor of 100. The PNEC aqua intermittent base on the test for acute toxicity in fish : PNEC aqua = 0.87 mg/l/ 100 = 0.0087 mg/l

PNEC STP: The PNEC STP was derived on the basis of the acute toxicity test for aquatic microorganisms (OECD 209) and applying an assessment factor of 100. PNEC STP = EC50: 625 mg/l/ 100 = 6.25 mg/l

PNEC sediment

The PNEC sediment was derived on the basis of the equilibrium partitioning method ( REACH: Technical guidance document for preparing the chemical safety assessment: R10.6.3).

PNEC marine sediment

The PNEC marine sediment was derived on the basis of the equilibrium partitioning method ( REACH: Technical guidance document for preparing the chemical safety assessment: R10.6.3).

PNEC soil

The PNEC soil was derived on the basis of the equilibrium partitioning method ( REACH: Technical guidance document for preparing the chemical safety assessment: R10.7.1).

PNEC oral: The NOAEL derived from a 28 day combined oral reproductive study (rat) is 300 mg/kg bw/d, a conversion factor (kg bw/kg food) and an assessement factor of 300 was applied.

Conclusion on classification

The substance is readily biodegradable and has a logPow of 4.35.

Ecotoxicological classification is required since the minimum aquatic toxicity (acute) is in the range of 0.1 to 1 mg/l and as logPow>4 – thus the substance should be classified with Acute 1, m-acute=1 and Chronic 1, m-chronic=1.
