Description of key information

Glucose syrups wheat hydrolyzed (WGS) is considered to be readily biodegradable on the basis of the results of a well reported, GLP-compliant, guideline ready biodegradability study.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The key study is a GLP-compliant, guideline study conducted according to the OECD guideline 301 B on Glucose syrups wheat hydrolyzed (Notox, 2010). Nominal initial test substance concentration was 12 mg/L total organic carbon (TOC). The test was performed using non-adapted activated sludge and the TOC and carbon dioxide (CO2) production were monitored over a 28-day period. The validity criteria were met. The test substance showed degradation (CO2 evolution) of 73 to 81% after 28 days. The reference substance sodium acetate exhibited degradation of 63% after 14 days. The test substance was considered to be readily biodegradable under the conditions of the test.
