Additional information

Since sodium acrylate dissociates in water to sodium- and acrylate-ions, the assessment of environmental fate and pathways for the present product is mainly based on the structural analogue acrylic acid (CAS# 79-10-7). According to the different investigations on acrylic acid, abiotic degradation in water, air or soil is unlikely. Furthermore, due to EpiWin calculations and analytical measurements on acrylic acid, adsorption is not expected. Consequently, Mackay Level 1 model showed that the substance will be mainly distributed into water.

Tests results on the biodegradation of sodium acrylate in different compartments are not available. However, the structural analogue acrylic acid is readily biodegradable. Moreover, based on the low log Pow bioaccumulation in organisms is unlikely.
