Effect of Surfactants and Solutes (Glucose and NaCl) on Solubility of Kavain—A Technical Note

Viscosity boosting effect of added ionic surfactant in nonionic wormlike micellar aqueous solutions

“…The CPP of C 18:1 SE is assumed at about ½, resulting in the formation of wormlike micelles in aqueous solution. However, CPP of SDS [44], which is ionic surfactant, is about 1/3 due to large repulsion between the head groups. Therefore addition of ionic surfactant varies the average CPP from 1/2 to 1/3 and the wormlike micelles become rodlike or spherical micelles, and hence the viscosity decreases.…”

1968–2008: 40 Years of Franco F. Vincieri's Natural Products Research

“…In 1998 Prof. Maria Camilla Bergonzi joined the group in order to start her PhD and during the following years, first as a post-doc and since 2005 as an aggregate professor, she has strongly supported my research. Authentication, quality control and stability testing have largely been performed using not only conventional [54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72] At the same time my scientific interest was driven by the improvement of bioavailability and technological features of extracts and HDPs, HMPs by formulation with liposomes, micelles, supramolecular complexes with cyclodextrins and their characterization by conventional methods (HPLC, DSC, UV, light scattering, dissolution tests) and innovative ones, such as NMR (ROESY and DOSY) [78][79][80][81][82][83][84].…”

“…An important part of my research concerns the improvement of bioavailability and technological features of extracts, HDPs and HMPs by innovative methods (liposomes, ethosomes, supramolecular complexes, micelles) for which my thanks go also to Prof. Maria Camilla Bergonzi and many graduating and PhD students, among them Benedetta Isacchi, whom I consider to be my right arm. These preparations were analysed both by conventional methods (HPLC, DSC, UV, light scattering, dissolution tests) [78,80,81] and innovative ones, such as NMR (ROESY and DOSY) [79,[82][83][84]. These studies were carried out on several supramolecular complexes between preparations of St. John's wort, kava-kava and cyclodextrins, micelles and liposomes (Figure 11).…”
