The Toxicology of the Polyethylene Glycols*

Journal of the American Pharmaceutical Association (Scientific ed.), 1950
Information developed during recent years upon the toxicological actions of the fluid and solid polyethylene glycols is summarized. This information has been re-interpreted and supplemented. Evidence presented in this report confirms the earlier work indicating that acute oral toxicity, dermal toxicity, and irritating properties of the polyethylene ...

Identification and quantification of polyethylene glycol types in polyethylene glycol methyl ether and polyethylene glycol vinyl ether

Journal of Chromatography A, 2009
Quantitative determination of polyethylene glycol (PEG) impurities in two monofunctional polyglycol types, PEG methyl ether (M-PEG) and PEG vinyl ether (V-PEG), has been carried out by reversed-phase liquid chromatography with evaporative light scattering detection (ELSD).

The Biodegradation of Polyethylene Glycols

1978
Publisher Summary This chapter discusses the biodegradation of polyethylene glycols. The glycols are compounds composed of from one to four units of ethylene oxide attached by ether linkages, and terminated with hydroxyl groups. The polyethylene glycols (PEGS) are ethylene oxide polymers which are represented by the following general formula: OCH ...

Polyethylene glycol

Applied Biochemistry and Biotechnology, 1995
The increasing demand of synthetic oligonucleotides for therapeutic and diagnostic purposes can be hardly satisfied by simply up-scaling the commercial synthesizers. The introduction of a liquid-phase method that utilizes a polymeric support soluble into the reaction media can overcome the shortcomings related to the heterogeneity of the solid phase ...
