Thin Films of Non-Ionic Poloxamer Surfactants: Thinning and Polymerisation of Poloxamer 407
1989Thin liquid draining films of poloxamer 407 block co-polymeric surfactant solutions have been investigated using reflected laser light intensity to determine film thicknesses. Only in IM NaCl do stable thin films form. A discontinuous stepwise thinning has been found in these systems with metastable film thicknesses of, for example, 80nm and 58nm ...

Prevention of Chlorhexidine Ototoxicity With Poloxamer in Rats
Otology & Neurotology, 2018Objective: Skin preparations, like chlorhexidine, are toxic to the inner ear, preventing their use as a preoperative skin disinfectant in the presence of a nonintact eardrum (e.g., perforation or tube). We aimed to determine if a poloxamer gel applied over perforated eardrums could prevent chlorhexidine ototoxicity.

Preparation of a novel poloxamer hydrogel
Journal of Applied Polymer Science, 2003AbstractPoloxamer hydrogels were prepared by photopolymerization from poloxamer macromer, which was synthesized by reaction of poloxamer 407 with acryloyl chloride. The synthesis of poloxamer macromer was confirmed using NMR and FTIR spectrometry. The gelation behavior and crystalline structure of poloxamer macromer was similar to those of poloxamer ...

Food Chemistry
In this study, we fabricated and characterized nanoparticles with a core/shell structure using lecithin and poloxamer. We also evaluated their ability to load proteins. At a lecithin/poloxamer ratio of 0.2, the sizes of lecithin/P188 (low molecular weight poloxamer) and lecithin/P338 (high molecular weight poloxamer) nanoparticles were 316.1 and 280.7 ...
