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.

Description of key information

The mean percentage biodegradation of MEDOL-10 calculated by biological oxygen demand (BOD) dissolved organic carbon concentration (DOC) and gas chromatography (GC) was 29.7, 33.1 and 100 % respectively. The percentage biodegradation by BOD and DOC were similar, while that obtained by GC resulted in a comparatively high value. The percentages of the metabolites remaining were estimated.

The remaining metabolite was identified as MEDOL-COOH (4-carboxyl-2-ethyl-2-methyl-1,3-dioxolane). This metabolite was oxidised from MEDOL_OH (4-hydroxymethyl-2-ethyl-2-methyl-1,3-dioxolane), one of the two hydrates of test item, the other being acrylic acid. Acrylic acid is readily biodegradable substance and disappear from the test solution, while MEDOL-OH and MEDOL-COOH remained.

Whilst some degradation was observed we cannot classify it as inherent therefore based on these results Medol 10 is concluded as not bidegradable.
