abstract = {A comparative analysis of the micellar and solubilizing
properties of two polyethylene glycol (PEG)-based
amphiphilic biocompatible excipients: Gelucire® 48/16 (Ge
48/16) and Tetronics® 1304 (T1304), in the presence and
absence of salt, was conducted. As there is a dearth of
research in this area, the study aims to shed light on the
behavior of these two nonionic surfactants and their
potential as nanocarriers for solubilizing pharmaceuticals.
Various techniques such as cloud point (CP), dynamic light
scattering (DLS), small-angle neutron scattering (SANS),
Fourier transform infrared spectroscopy (FT-IR), UV
spectrophotometry, and high-performance liquid
chromatography (HPLC) were employed. The solubility of
quercetin (QCT), a flavonoid with anti-inflammatory,
antioxidant, and anti-cancer properties, was evaluated and
the interaction between QCT and the micellar system was
examined. The analysis revealed the occurrence of strong
interactions between QCT and surfactant molecules, resulting
in enhanced solubility. It was observed that the micellar
size and solubilizing ability were significantly improved in
the presence of salt, while the CP decreased. Ge 48/16
exhibited superior performance, with a remarkable increase
in the solubility of QCT in the presence of salt, suggesting
its potential as an effective nanocarrier for a range of
pharmaceutics, and yielding better therapeutic outcomes.},
