Additional information

Toxicity to microorganisms:

According to REACH CSA guidance document R7b section R. information from this Ready Biodegradation study (GLP and run according to Japanese Guideline study on microbial degradation of chemical substances (MHLW/PFSB Notification No. 1121002 Nov 21, 2003, METI/MIB Notification No. 2 Nov 13 2003, and MOE/EPB Notification No. 031121002 last revised Nov 20, 2006)) is considered as reliable as the compound degrades well and did not inhibit the degradation of a positive control. The exposure concentration of 100 mg/l is therefore considered as the NOEC of Molyvan 855 for this 28 day study.
