Polyethylene glycols as embedding media in histochemical work.
The embedding and sectioning of tissues in paraffin is a slow process. For histochemical purposes, especially for the demonstration of enzymes, preparation of tissue sections in paraffin is not desirable since the exposures of tissues to high temperatures and to several changes of dehydrating and clearing agents are detrimental to the preservation of enzymes. Gomori's (1946) experience with the...
متن کاملMicrobial degradation of polyethylene glycols.
Mono-, di-, tri-, and tetraethylene glycols and polyethylene glycols (PEG) with molecular weight up to 20,000 were degraded by soil microorganisms. A strain of Pseudomonas aeruginosa able to use a PEG of average molecular weight 20,000 was isolated from soil. Washed cells oxidized mono- and tetraethylene glycols, but O2 consumption was not detectable when such cells were incubated for short per...
متن کاملSafety assessment on polyethylene glycols (PEGs) and their derivatives as used in cosmetic products.
This assessment focusses on polyethylene glycols (PEGs) and on anionic or nonionic PEG derivatives, which are currently used in cosmetics in Europe. These compounds are used in a great variety of cosmetic applications because of their solubility and viscosity properties, and because of their low toxicity. The PEGs, their ethers, and their fatty acid esters produce little or no ocular or dermal ...
متن کاملLow Molecular Weight Polyethylene Glycols as Matrix to Obtain Solid Dispersions of Sulfanilamide
Objective: The objective of the present study is a determination of optimal ratios of polyethylene glycol:sulfanilamide at which formation of solid dispersion is observed. Also study the effect of the polymer on the limiting solubility of sulfanilamide in water. Methods: Using low-temperature differential scanning calorimetry (DSC), it was made possible to obtain solid dispersions of sulfanilam...
متن کاملAerobic and anaerobic biodegradation of polyethylene glycols using sludge microbes
The aerobic and anaerobic biodegradation of polyethylene glycols (PEGs) in a model wastewater was investigated employing sludge microbes from Xiamen Terylene plant. The effect of molecular weight (MW) on the aerobic/anaerobic biodegradation of PEGs was assessed by performing shake flasks/sealed flasks experiments, respectively, using organic model wastewater containing PEG 600, 6000 and 20,000....
