Description of key information

From the water surface, Isobutyl acrylate will slowly evaporate into the atmosphere.
Henry's Law constant at 25 °C = 21.9 Pa*m3/mol

Key value for chemical safety assessment

Additional information

The Henry's Law Constant was calculated by QSAR (SRC HENRYWIN v3.10) (BASF SE, 2008). The constant was estimated to be 21.9 Pa*m3/mol at 25 °C indicating slow evaporation of isobutyl acrylate from the water surface into the atmosphere.
