Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- Glycol ethers and their acetates are readily absorbed following oral administration or inhalation. Dermal absorption is also an important route.
- Details on distribution in tissues:
- Glycol ethers are readily distributed throughout the body - no substantial accumulation of the parent compound has been observed. In contrast to the metabolites of ethlene glycol methyl ether and ethylene glycol ethyl ether, the metabolite of ethylene glycol butylene ether shows no evidence of significant accumulation.
Any other information on results incl. tables
In the metabolism of the longer chain ethylene glycol ethers (ethylene glycol butyl ether, -propyl ether, -isopropyl ether and -phenyl ether), methoxyacetic and ethoxyacetic acid are not formed.
The alkoxyacetic acid metabolites, methoxyacetic acid and ethoxyacetic acid, have been found to be responsible for bone marrow depression, testicular atrophy, developmental toxicity, and immunotoxicity in animals treated with methyl- and ethyl-substituted ethylene glycol ethers. As these metabolites are not formed in the metabolism of the longer chain ethylene glycol ethers (ethylene glycol butyl ether, -propyl ether, -isopropyl ether and -phenyl ether) these materials do not cause the described effects.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
