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.

Due to ready biodegradability under aerobic conditions no further investigations on biodegradation are considered necessary in accordance with REACH Regulation Annex IX,, column 2 (soil) and Annex IX, (sediment).

According to REACH Regulation, Annex VIII,, column II a study on hydrolysis as a function of pH does not need to be conducted as the substance is readily biodegradable.

Although ready biodegradability has been shown for the substance, a calculation to estimate the adsorption/desorption potential of Sucroglyceride C16-18 is provided. A calculation of a single Koc for the UVCB substance is not feasible. Thus, the Koc of the main constituents of Sucroglyceride C16-18 were calculated separately using EPI suite v4.00 KOCWIN v2.00. As a log Kow below 3 and high water solubility indicates no potential for adsorption, it was not considered necessary to calculate Koc for Sucrose and Glycerol (log Kow of -3.7 and -1.76, respectively; water solubility 2.12E+06 mg/L and 5.30E+06 mg/L, respectively).

The calculated log Koc of the fatty acids (Palmitic acid, Stearic acid) were in the range of 4.00 to 4.59, increasing with higher chain length.

The log Koc of the monoglycerides were in the range of 3.26 to 4.07, indicating no strong binding potential to soil particles. Although the model is only valid for undissociated substances, and Palmitic acid and Stearic acid are weak acids which will exist almost entirely in the anion form in the environment, anions generally do not adsorb more strongly to soil containing organic carbon and clay than their neutral counterparts. It is therefore assumed that the adsorption potential for the dissociated forms is not higher.
