Poly(ethylene glycol) or Poly(ethylene oxide)? Magnitude of end-group Contribution to the Partitioning of Ethylene Oxide Oligomers and Polymers between Water and Organic Phases
Ethylene oxide oligomers and polymers (hereafter referred to as PEO) are amongst the most commonly used substances in pharmaceutical and other industrial formulations. Depending on the oligomer/polymer molar mass, they have been called poly(ethylene glycol)s or poly(ethylene oxide)s, the former applied to smaller ones to suggest a glycolic chemical nature attributed to significant contributions...

متن کاملVariables affecting simulated use determination of residual ethylene oxide in medical devices.
In autumn 1993, AAMI/ST/WG 63, Sterilization Residuals Working Group undertook the task of studying factors involved in determining the amount of residual ethylene oxide in medical devices after sterilization and developing a protocol for controlling the relevant variables. The protocol was evaluated by conducting a round robin study consisting of 8 participating laboratories from around the co...
متن کاملSterilization by ethylene oxide.
Although sterilization by steam under pressure and by hot air are procedures which are now well understood and efficient when properly conducted, there is an increasing number of objects in medical or surgical use which are too heat labile to be so treated. It is for such items as plastic catheters, disposable plastic syringes, and prostheses that ethylene oxide has been proposed as a convenien...
متن کاملDetermination of low-level residual ethylene oxide by using solid-phase microextraction and gas chromatography.
Current methods of analysis for ethylene oxide (EO) in medical devices include headspace and simulated-use extractions followed by gas chromatography with either a packed or a capillary column. The quantitation limits are about 0.5-1.0 microg/g for a packed column and about 0.1-0.2 microg/g for a capillary column. The current allowable levels of EO on medical devices sterilized with EO gas as o...
