EC number: 203-990-4
CAS number: 112-61-8
Methyl stearate (CAS 112-61-8) is readily biodegradable according to OECD criteria.
One study, investigating the ready biodegradability of Fatty
acids, C16-18 and C18-unsatd., Me esters (CAS 67762-38-3), was used as
read across for methyl stearate (CAS 112-61-8). This substance is
structurally and compositionally related to methyl stearate. In this
GLP-study (Richterich, 2001) according to OECD 301D (Closed Bottle Test)
activated sludge (domestic) was used as inoculum. At test termination
after 28 days a degradation of 87% was observed and the 14 -day-window
was reached. Therefore, the read across substance is readily
biodegradable. Based on the category it can be concluded that methyl
stearate (CAS 112-61-8) is also readily biodegradable.
