Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

From OECD studies, there is sufficient evidence from various teststo assure that hexylcinnamaldehyde is readily biodegradable meeting the 10 day window .

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Three studies were located on ready biodegradability. One study used adapted sludge and is therefore not valid for evaluating ready biodegradation. A second which achieved >60% biodegradation but failed the 10 day window, used a modified Sturm test under closed conditions to prevent loss due to volatility. The third study was conducted according to OECD Guideline 301F. In the study it was shown that 97% of the substance was mineralised within 28 days meeting the 10 day window criterion.
