Additional information
Data waiving (study scientifically not necessary/other information available): In accordance with Column 2 of REACH Annex IX, these studies do not need to be conducted since the substance is expected to have a low potential for bioaccumulation (Log Kow <3).
Supporting studies: Bioaccumulation (BCF) of main consituents has been calculated by EPI-Suite, EPA (USA), BCFBAF v3.01:
2-[3-(2{3-[4,5-dihydroxy-1,3-dioxolan-2-yl)(hydroxy)methyl]-4,5-dihydroxy-2-oxoimidazolidin-1-yl}-1,2-dihydroxyethyl)-4,5-dihydroxy-2-oxoimidazolidin-1-yl]-2-hydroxyacetaldehyde: The BCF of the substance was estimated to be 3.162 L/kg wet-wt (log BCF from regression-based method = 0.500).
2-[4,5-dihydroxy-3-(1-hydroxy-2-oxoethyl)-2-oxoimidazolidin-1-yl]-2-hydroxyacetaldehyde: The BCF of the substance was estimated to be 3.162 L/kg wet-wt (log BCF from regression-based method = 0.500).
4,5-dihydroxyimidazolidin-2-one: The BCF of the substance was estimated to be 3.162 L/kg wet-wt (log BCF from regression-based method = 0.500).
(2S)-2-[(4S,5S)-3-[(S)-[(4R,5R)-4,5-dihydroxy-1,3-dioxolan-2-yl](hydroxy)methyl]-4,5-dihydroxy-2-oxoimidazolidin-1-yl]-2-hydroxyacetaldehyde: The BCF of the substance was estimated to be 3.162 L/kg wet-wt (log BCF from regression-based method = 0.500).
1-{2-[4,5-dihydroxy-3-(1-hydroxy-2-oxoehtyl)-2-oxoimidazolidin-1-yl]-1,2-dihydroxyethyl}-3-(1,2-dihydroxyethyl)urea: The BCF of the substance was estimated to be 3.162 L/kg wet-wt (log BCF from regression-based method = 0.500).
