Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Acute aquatic studies conducted using sodium isobutyrate solution (reaction mass of lithium 3-hydroxy-2,2,4-trimethylpentanoate and lithium isobutyrate and sodium 3-hydroxy-2,2,4-trimethylpentanoate and sodium isobutyrate) are available for fish, Daphnia magna, algae and activated sludge microorganisms.

The following PNECs were derived:

PNEC Aqua (freshwater) - Based on an assessment factor of 1000, the PNEC is 0.1 mg/L.

PNEC Aqua (marine water) - Based on an assessment factor of 10,000 the PNEC is 0.01 mg/L

PNEC Aqua (STP)- Based on an assessment factor of 10 the PNEC is 100 mg/L

No PNECs for other compartments (freshwater intermittent releases, air, sediment, soil, or secondary poisoning) are considered necessary

In the chemical safety assessment performed according to Article 14(3) in connection with Annex I section 3 (Environmental Hazard Assessment) no hazard was identified. Therefore according to REACH Annex I (5.0) exposure estimation is not necessary.

Conclusion on classification

No classification is triggered based on the available data, according to EEC directive 79/831/EEC Annex VI, Part II (D) as described in Commission Directive 93/21/EEC or regulation (EC) No 1272/2008. No hazards for the environment have been identified.
