EC number: 203-933-3
CAS number: 112-07-2
Valid studies only reported:
P putida, 17hr EC10=722mg/l, EC50=964mg/l
Sewage micro-organisms, 3 hr EC50>1000mg/l, IC50=2800mg/l
A guideline study using activated sludge respiration inhibition as a
measure of toxicity to micro-organisms showed an EC20 of >=900mg/l. In a
guideline study where basic details were reported, the bacteria P.
putida were exposed to 2 -butoxyethyl acetate to concentrations in
excess of 1g/l. The study concluded a 17hr EC50 of 964mg/l and an EC10
(which can be considered a NOEC) of 720mg/l. In a bacterial growth
inhibition test using sewage microorganisms and turbimetry as the end
point, the substance was found to inhibit growth by 50% at a
concentration of 2800mg/l (IC50 =2800mg/l). It can be concluded that
the substance has relatively low toxicity to bacteria.
