Metabolite Identification
Common NameOctaethyleneglycol monododecyl ether
DescriptionOctaethyleneglycol monododecyl ether, also known as N-dodecyl octaethylene glycol monoether or C-12-e-8, belongs to the class of organic compounds known as polyethylene glycols. These are oligomers or polymers of ethylene oxide, with the general formula (C2H4O)n (with n>=3). Based on a literature review a significant number of articles have been published on Octaethyleneglycol monododecyl ether. This compound has been identified in human blood as reported by (PMID: 31557052 ). Octaethyleneglycol monododecyl ether is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Octaethyleneglycol monododecyl ether is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
