Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Results and discussion

Toxicokinetic / pharmacokinetic studies

Details on absorption:
The absorption capacity of 2-(2-chloroethoxy) ethanol is low (as has been stated section 5.4.1 of the dossier), which is also supported by the fact that the bioaccumulation factor for the substance is much lower and so even after the exposure the absorption capability will be less in this case.
Details on distribution in tissues:
In case the substance,2-(2-chloroethoxy) ethanol, is absorbed (though in small quantity) it will not be accumulated in the body. This is supported by the fact that the substance have not only low BCF value (as mentioned in section 5.3.1 of the same dossier) but also have a moderate level of Kow which will support the reasoning that though the substance will enter the body but will get distributed through the lipid in the body.
Details on excretion:
Further to this distribution after the absorption process, the excretion process through urine would be faster as the molecular weight of the substance, 2-(2-chloroethoxy) ethanol, is > 300 and this is a favourable value for excretion via the urine route.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): other: non bioaccumulation potential based on estiamtion results
Executive summary:

The substance, 2-(2-chloroethoxy) ethanol, do not have a bioaccumulation potential based on estiamtion results supported by the facts of physicochemical parameters and persistant nature of the substance.
