Description of key information
Sucroglyceride C12‐18, C18unsatd. 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 anaerobic biodegradation of Sucroglyceride C12-18, C18unsatd. was investigated in a study conducted according to ECETOC Technical Report no 28/SS-EN ISO 11734 over a period of 70 days and using digested sludge as inoculum. The test item proved to be completely anaerobic biodegradable, as biodegradation 75%-80% of theoretical gas production was achieved.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Sucroglyceride C12‐18, C18unsatd. 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 C12‐18, C18unsatd. reached >90%.
This finding is supported by a similar biodegradation study on the structural analogue Sucroglyceride C12:
Biodegradability of the test substance was tested according to OECD guideline 301D (Ready Biodegradability: Closed Bottle Test) and EU Method C.6 (Degradation: Chemical Oxygen Demand) at test concentrations of 3.23 and 5.33 mg/L. Because the test substance is insoluble in water the stock solution was prepared with an emulsifier. The reference substance sodium acetate (5 and 10 mg/L) was readily biodegradable within 28 days.
The test substance is readily biodegradable within 28 days. Complete degradation was reached after 28 days.
The anaerobic biodegradation of Sucroglyceride C12-18, C18unsatd. was investigated in a study conducted according to ECETOC Technical Report no 28/SS-EN ISO 11734 over a period of 70 days and using digested sludge as inoculum. The biodegradation rate was determined by measurement of methane and carbon dioxide evaluation.This study is regarded as reliable with restriction (documentation lacking detail). The test item proved to be completely anaerobic biodegradable, as biodegradation 75%-80% of theoretical gas production was achieved.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
