According to Q(SAR) data using SRC AOP, isobutyl acrylate will be slowly degraded by photochemical processes after exposure to the air reacting with the photochemically produced hydroxyl radicals and with ozone (calculated half-life for a 24-hour day and 0.5E06 OH/cm3: 27.98 hours; for a 24-hour day and 7E11 O3/cm3: 6.55 days) (BASF SE, 2008).

Based on Q(SAR) data using SRC HYDROWIN v1.67, iBA will be slowly hydrolysed in contact with water (calculated half-life at pH 7 and 25 °C: 16.5 years; at pH 8 and 25 °C: 1.6 years) (BASF SE, 2008).
