In this study, febantel was dissolved under increased temperature in a nonionic surfactant Lutrol L44® and subsequently mixed into an aqueous maltodextrin solution. After 8h under static conditions, coacervation or phase separation took place. (1)H NMR spectra and HPLC analysis showed that the upper phase contained mainly all febantel, while no febantel was detected in the lower phase. Fluoresc...
The separation of proteins by polyelectrolyte coacervation or precipitation is based on electrostatically-driven complex formation. We have investigated complexation between the globular protein BSA and the polyelectrolyte poly(dimethyldially1ammonium chloride) (PDMDAAC) using light-scattering techniques to monitor solution turbidity. Turbidimetric pH titrations were used to determine the speci...
A review of the early development of the thermodynamics of the complex coacervation phase separation
It is aimed to achieve the optimized for vitamin E (dl-α-tocopherol acetate) micro-encapsulation through complex coacervation at high efficiency with this study. The response surface methodology (RSM) was used optimize microencapsulation state of E. microencapsulated tocopherol investigated in terms two variables including amount core material (vitamin E) and concentration surfactant (SDS). Acc...
Solid lipid nanoparticles (SLN) of fatty acids (FAs) were prepared with a new, solvent-free technique based on FAs precipitation from their sodium salt micelles in the presence of polymeric non-ionic surfactants: this technique was called 'coacervation'. Myristic, palmitic, stearic, arachidic and behenic acid were employed as lipid matrixes. Spherical shaped nanoparticles with mean diameters ra...
