12.2 Persistence and degradability
Methyltrimethoxysilane
Biodegradability: Based on stringent OECD test guidelines, this material cannot be
considered as readily biodegradable; however, these results do not necessarily mean that the
material is not biodegradable under environmental conditions.
Biodegradation: 54 %
Exposure time: 28 d
Method: Regulation (EC) No. 440/2008, Annex, C.4-A
octamethylcyclotetrasiloxane
Biodegradability: Material is expected to biodegrade very slowly (in the environment). Fails
to pass OECD/EEC tests for ready biodegradability.
10-day Window: Not applicable
Biodegradation: 3.7 %
Exposure time: 28 d
Method: OECD Test Guideline 310
Stability in Water (1/2-life)
Hydrolysis, DT50, 69.3 - 144 Hour, pH 7, Half-life Temperature 24.6 °C, OECD Test Guideline
111
Dodecamethyl cyclohexasiloxane
Biodegradability: Based on stringent OECD test guidelines, this material cannot be
considered as readily biodegradable; however, these results do not necessarily mean that the
material is not biodegradable under environmental conditions.
10-day Window: Fail
Biodegradation: 4.5 %
Exposure time: 28 d
