Parent compound: no data

Hydrolysis product ethanol: 7 -d ErC50 = 3690 mg/L; 7 -d NOEC = 280 mg/L (OECD, 2005)

Toxicity to microorganisms:

Parent compound: no data

Hydrolysis product ethanol: 3 -h EC50 > 1000 mg/L (Kleĉka et al., 1985)

Analogous hydrolysate (Methanol, HCl, CO2): 30 -min EC50 > 1000 mg/L (BASF AG, 1999)

An inhibition of the degradation activity of activated sludge is not expected when introduced to biological treatment plants in appropriate low concentrations.
