Abstract Background Self-emulsifying system-based lipstick may prove to have the potential of enhancing moisturizing characteristics and delivering hydrophobic drug antifungal drugs for management lip fungal infection, especially candidiasis. In this study, self-emulsifying delivery system (SEDDs) ketoconazole was obtained using IPM (Oil), Tween 80 (surfactant), PEG 400 (co-surfactant). The med...

The objectives of present investigations were to optimize concentration of oil, surfactant and cosurfactant by pseudoternary phase diagrams and to develop a stable formulation of self emulsifying drug delivery system (SEDDS) in order to enhance the dissolution rate of poorly soluble Irbesartan (IBS) by SEDDS. Pseudoternary phase diagrams were constructed to identify the self emulsifying region....

Sugar fatty acid esters are practical importance and have a variety of applications that include surfactants and as an emulsifying agent. In this study, we report glucose stearate synthesis using lipase-Fe3O4 nanoparticles catalyst. The influence of various reaction factors, such as silica gel concentration, molar ratio of sugar/acid, reaction temperature and speed of agitation on esterificatio...

A new strain Renibacterium salmoninarum 27BN was isolated for its capacity to utilize n-hexadecane as sole substrate. Growth on n-hexadecane was accompanied with the production of glycolipid surface active substances detected by surface pressure lowering and emulsifying activity. Glycolipid detection by thin layer chromatography and infrared spectra analyses showed for the first time that Renib...

Abstract The effects of heat treatment (90 °C, 5 or 30 min) and enzymatic crosslinking with transglutaminase (TG, 10, 100 1000 nkat/g protein) on emulsifying gelling properties faba bean protein isolate (FPI) were studied. Heat FPI caused a clear shift in far-UV CD spectra towards random coil structure an increase surface hydrophobicity from 181 to 504 RFU. TG crosslinked heat-treated more effi...

A rapid turbidimetric method for the determination of serum lipase is described. The substrate is a nearly pure triglyceride in Tris buffer, with sodium deoxycholate as the emulsifying agent. The method is equal in sensitivity to the titrimetric measure of serum lipase using a modified Cherry-Crandall substrate. The serum of patients with acute pancreatitis contains a lipase with optimal action...

Fatty-acylated sericin {1:0.7 molar ratio of sericin (Mr 18,700) to oleic acid} was prepared by lipase-catalyzed solid-phase synthesis in n-hexane containing oleic acid to endow sericin with interfacial properties. Acylation with oleic acid was confirmed by 1H-NMR. The fatty-acylated sericin exhibited superior emulsifying activity index and emulsion stability in the presence of 0-0.5 M NaCl, in...

We compared two methods for the direct selective measurement of hepatic lipase and lipoprotein lipase activities in human plasma after intravenous administration of heparin. Except for the emulsifier (gum arabic vs lecithin), the two assay media for hepatic lipase are essentially similar. Results for hepatic lipase by these two assays correlate well (r = 0.99). The assays for lipoprotein lipase...
