Additional information

Evaporation of Octadecanoic acid, ester with 2,2'-[oxybis(methylene)]bis[2-(hydroxymethyl)-1,3-propanediol] (CAS 70969-57-2) to the atmosphere is not expected due to the low vapour pressure of the substance. Thus indirect photodegradation is no relevant degradation pathway for the substance since the substance is not likely to be present in the atmosphere. Due to the low water solubility (< 1.7E-4 mg/L) abiotic hydrolysis is considered as technically not feasible and does therefore not need to be conducted. The QSAR calculation shows a half-live > 1 year (HYDROWIN v2.00) for the substance.
