Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests

Description of key information
Isononyl benzoate was degraded by 89 % over the complete study period
and by > 60 % in the course of 10 days after the time when
biodegradation had achieved 10 %. Therefore, isononyl benzoate is
considered to be "readily biodegradable".
The test item isononyl benzoate studied reached a degree of degradation
from headspace gas of 41% in the course of 60 days (mean of the test
item batches). The degree of the total biodegradation (biodegradation
from biogas and TIC-analyses) reached 55%. So, the test item can be
considered as biodegradable under anaerobic conditions.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
- Type of water:
- freshwater
Additional information
Benzoic acid, nonyl ester, branched and linear was tested in an OECD 301B study (modified Sturm test / CO2 evolution test) for ready biodegradability. The test item studied reached a degree of degradation of 89 % in the course of 28 days. Since Isononyl benzoate was degraded by > 60 % in the course of 10 days after the time when biodegradation had achieved 10 %, isononyl benzoate is considered to be "readily biodegradable".
Isononyl benzoate was tested in a DIN EN ISO 11734 (1998) study (comparable to OECD 311) for biodegradability under anaerobic conditions. Washed digested sludge, containing very low amounts of inorganic carbon, is diluted to total soids concentration of 1 g/L and incubated an 35 +- 2 °C in sealed vessels with a test chemical at an organic carbon concentration of 20 mg/L to 100mg/L for up to about 60 days.
The increase in headspace pressure in the test vessels resulting from the gas production of carbon dioxid and methane is measured. A considerable amount of carbon dioxine will be dissolved in water or transfomed to hydrogen carbonate or carbonate under the conditions of the test. This inorganic carbon is measured at the end of the test.
The test item isononyl benzoate studied reached a degree of degradation from headspace gas of 41% in the course of 60 days (mean of the test item batches). The degree of the total biodegradation (biodegradation from biogas and TIC-analyses) reached 55%. So, the test item can be considered as biodegradable under anaerobic conditions.
