3.4 MODE OF DEGRADATION IN ACTUAL USE
3.5 BIODEGRADATION
Type :
Inoculum : other
Remark : As potassium methylate rapidly hydrolyzes in water to methanol and
potassium hydroxide, the data of the hydrolysis products are relevant for
this substance as well. SIDS dossiers, SIARs and SIAPs are available for
the degradation products.
Methanol is readily biodegradable (BOD5 is 76-82%).
Biodegradability is not applicable to potassium hydroxide.

3.6 BOD5, COD OR BOD5/COD RATIO
3.7 BIOACCUMULATION
Species : other: expert judgement
Exposure period : at °C
Concentration :
Remark : As sodium and potassium methanolate react with water under formation of
sodium and potassium hydroxide and methanol, an octanol-water partition
coefficient cannot be experimentally established and bioaccumulation of
the substances themselves is unlikely.
