Description of key information

Additional information

Biodegradation: Coconut oil, reaction product with polyethylene glycol and trimethylolpropane is "readily biodegradable".

Bioaccumulation:

The BCF and BAF of all main component are very low, the BCF are between 3.162 and 122.5 L/kg ww regression-based method using the program BCFBAF v3.01 (Part of US EPA EPI Suite v4.00). In addition, a BAF and BCF (upper trophic) are beween 0.8933 and 33.94 calculated using the method of Arnot-Gobas.

 

The low BCF/BAF values indicate a low potential of the test item Coconut oil, reaction products with polyethylene glycol and trimethylolpropane for bioaccumulation in aquatic organisms.

Hydrolysis:

In accordance with REACH Annex VIII column 2, the study for the whole test item does not need to be conducted if the substance is readily biodegradable.

Constituents: Hydrolysis rate constants cannot be estimated for 1,2,3-Propanetriol and 2-ethyl-2-(hydroxymethyl)propane-1,3-diol. The Kb Half-Life at pH 8 of the main consituents Fatty acids, coco, esters with trimethylolpropane, Fatty acids, coco, ethoxylated and Glycerides, C12-18 mono-, di- and tri- were between 129.295 days and 2.331 years. The Kb Half-Life at pH 7 of the main consituents Fatty acids, coco, esters with trimethylolpropane, Fatty acids, coco, ethoxylated and Glycerides, C12-18 mono-, di- and tri- were between 3.54 and 23.313 years.

Adsorption/desorption:

The Soil Adsorption Components of the main components 2-ethyl-2-(hydroxymethyl)propane-1,3-diol and 1,2,3-Propanetriol are very low, indicating a very high soil mobility potential, the Soil Adsorption Components of the main components Glycerides, C12-18 mono-, di- and tri- and Fatty acids, coco, ethoxylated are low, indicating a high soil mobility potential and the Soil Adsorption Components of the main component Fatty acids, coco, esters with trimethylolpropane are high until medium, indicating a medium until low soil mobility potential. The Koc are between 0.1345 - 729.6 L/kg. Therefore altogether it can be concluded that the adsorption of Coconutoil, reaction products with polyethylene glycol and trimethylolpropane is low.
