Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key study: Read-across approach from experimental data on the analogue substance MPKO: Test method OECD Guideline 203, GLP study. The 96h LC50 value for rainbow trout was determined to be > 117 mg/L while the NOEC was 117 mg/L and the LOEC was >117 mg/L. Therefore, It can be concluded that the substance is not acutely toxic for fish.

 

Short term invertebrates

Key study: Read-across approach from experimental data on the analogue substance MPKO: Test method OECD Guideline 202, GLP study. The 48h EC50 (immobilisation) value forDaphnia magnawas determined to be >117 mg/L, while the NOEC was >= 117 mg/L. Therefore, it can be concluded that the substance is not acutely toxic for invertebrates.

Short term algae

Key study: Read-across approach from experimental data on the analogue substance MPKO: Test method OECD Guideline 201, GLP study. The EbC50 (biomass) was determined to be 58 mg/L (95% CL: 55 -64 mg/L) and the ErC50 (growth rate) was 103 mg/L (95% CL: 84 -117 mg/L). The NOEC for both biomass and growth rate was 37 mg/L. Therefore, it can be concluded that the substance is not toxic for algae.

Toxicity to microorganisms

Key study: Read-across approach from experimental data on the analogue substance OS1600: Test method OECD Guideline 301B, GLP study. The NOEC was determined to be 22.2 mg/L since in the toxicity control with the analogue substance more than 25% degradation occurred within 14 days (32 % based on ThCO2). It can be considered that the test substance does not inhibit microbial activity.
