Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Description of key information

Data for repeated dose toxicity are available from a combined 28-day repeated dose toxicity study with the reproduction/developmental toxicity screening test in rats performed according to OECD and EU guidelines as well as GLP principles. From the results of the study, a NOAEL of >=1000 mg/kg bw/d in both male and female rats was established based on lack of treatment related effects and no mortalities observed.

Key value for chemical safety assessment

Repeated dose toxicity: via oral route - systemic effects

Endpoint conclusion
Dose descriptor:
NOAEL
1 000 mg/kg bw/day
Species:
rat

Additional information

Treatment with Biomass residue obtained after B2 production by oral gavage in male and female Wistar (Han) rats at dose levels of 100, 300 and 1000 mg/kg bw/day revealed no parental toxicity up to 1000 mg/kg bw/day. No reproduction and developmental toxicity was observed for treatment up to 1000 mg/kg bw/day. Based on these results, a parental, reproductive and developmental No Observed Adverse Effect Level (NOAEL) of at least 1000 mg/kg bw/day was derived.

Justification for classification or non-classification

Based on the results of the 28-day repeated dose toxicity study with the reproduction/developmental toxicity screening test, at this moment the substance does not need to be classified according to the CLP Regulation (EC) 1272/2008 and Council Directive 67/548/EEC (DSD).
