Description of key information

The ready biodegradation of Sucroglyceride C16-18 was investigated in a study conducted according to OECD Guideline 301 D (closed bottle test) over a period of 28 days and using domestic sewage as inoculum. The test item proved to be readily biodegradable and fulfilling the 10-d window criterion.  The biological degradability of the test substance amounts to >95 % BOD of COD after 28 days. 

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Sucroglyceride C16-18 is readily biodegradable and fulfils the 10 d window criterion, based on the test results of a study conducted according to OECD Guideline 301 D (closed bottle test) using domestic sewage as inoculum.The biodegradation rate was determined by measurement of oxygen consumption. Inoculum blank and procedural/functional control with the reference substance sodium acetate were performed. After 28 days the degradation of Sucroglyceride C16-18 reached >95%.
