Reaction mass of 3-({[2,2-dimethyl-3-({[2-(2-{[(prop-2-en-1-yloxy)carbonyl]oxy}ethoxy)ethoxy]carbonyl}oxy)propoxy]carbonyl}oxy)prop-1-ene and 3-{[(2,2-dimethyl-3-{[(prop-2-en-1-yloxy)carbonyl]oxy}propoxy)carbonyl]oxy}prop-1-ene and diallyl 2,2'-oxydiethyl dicarbonate

Endpoint summary

Additional information

For justification of the intended read-across approach of Diallyl-2,2 ´-oxydiethyl dicarbonate (EC 205 -528 -7) to Reaction mass of 2,2'-oxydiethanol and 2,2-dimethylpropane-1,3-diol and diallyl 2,2'-oxydiethyl dicarbonate and diallyl carbonate and pentaerythritol' (EC 700 -742 -1), please refer to the general discussion of environmental fate and pathways. Adsorption / desorption The adsorption / desorption properties of Diallyl-2,2`-oxydiethyl dicarbonate (EC 205-528-7) have not to be experimentally determined in accordance with REACH regulation, Annex VIII, column 2. The reason is the low logPow of 1.54, indicating that the substance can be expected to have a low potential for adsorption. For completeness the organic-normalized sorption coefficient for soil (Koc) was calculated with the help of the computer program EPIWIN software KOCWINv2.00 by US-EPA (Chemservice S.A., 2010). This tool utilizes two different models: the Salbjic molecular connectivity (MCI) method with improved correction factors (and therefore taken more seriously into account) and the traditional method, which is based on the logarithmic octanol-water partition coefficient, logPow. Regarding the MCI method a value of 20.69 L/kg is reported, whereas the traditional method gives a result of 16.9 L/kg. Henry´s Law Constant

The substance specific Henry´s Law Constant was also determined by calculation using the EPIWIN software HENRYWINv3.20 by US-EPA (Chemservice S.A., 2010). It was only possible to receive a result with the help of the Bond Method, which was 1.88 E-002 Pa*m³*mol-1. The Group Method showed an incomplete result.
