Description of key information

Additional information

Due to the physico-chemical properties such as low water solubility (< 1.7E-4 mg/L), low volatilization potential (VP < 0.0001 Pa) and log Koc (> 10), Octadecanoic acid, ester with 2,2'-[oxybis(methylene)]bis[2- (hydroxymethyl)-1,3-propanediol] (CAS 70969-57-2) is expected to mainly distribute to soil and sediment. According to the Guidance on information requirements and chemical safety assessment, Chapter R7.b (ECHA, 2017) once insoluble chemicals enter a standard sewage treatment plant, these substances are expected to be removed from the water column to a significant degree by adsorption to sewage sludge. Therefore the release to surface waters, and thereby exposure of sediment and soil, is considered as marginally.
