EC number: 214-244-2
CAS number: 1117-31-3
One experimental study according to OECD 301B confirmed that
1,3-butylene diacetate (CAS 1117-31-3) is readily biodegradable
according to the OECD criteria (82% biodegradation after 28 d). The
degradation via abiotic hydrolysis is not considered to be a relevant
degradation pathway in the environment since QSAR results using HYDROWIN
v2.00 resulted in DT50 values > 1 yr at pH 7. Considering the high water
solubility (≤ 50 g/L) and the low potential for adsorption to organic
soil and sediment particles (log Koc: 1 - 1.52, KOCWIN v2.00), the main
compartment for environmental distribution is expected to be the surface
water. Nevertheless, persistency in this compartment is not expected
since the substance is readily biodegradable and it will be rapidly and
ultimately degraded in sewage treatment plants and natural waters.
Evaporation from the water phase into air and the transport through the
atmospheric compartment is not expected in significant amounts
for1,3-butylene diacetate based on the low Henry’s Law
constant (< 1 Pa m³/mole (HENRYWIN v3.20); Müller, 2011) and the vapour
pressure of 16.61 Pa. However, if released into air,1,3-butylene diacetate
is susceptible to indirect photodegradation by OH-radicals with a
DT50 value of 52.60 h (AOPWIN v1.92). Therefore, the potential for
accumulation in air and the subsequent transport to other environmental
compartments is low. The potential for bioaccumulation of1,3-butylene diacetate
is assumed to be low based on the log Kow of 1.31.
