Piroxicam belongs to BCS class II and has low solubility. Self-nanoemulsifying drug delivery systems (SNEDDS) are considered a potential approach for increasing the solubility release of piroxicam. This study aimed select components component ratios piroxicam SNEDDS using fractional factorial design 26-2 (FFD). The variables used in DFT development type concentration oil (triacetin oleic acid),...

ABSTRACT. The recent research focused on the green synthesis of silicon dioxide nanoparticles, SiO2@Cellulose Zizyphus Spina-Christi nanocomposites, and L-Arginine@SiO2@Cellulose nanocomposites using cellulose as a new polymeric surfactant. structures nanoparticles were characterized by different spectroscopy microscopy techniques. Nanoparticles utilized to determine concentration chromium, cad...

This review summarizes a large set of related experimental results about protein adsorption and drop coalescence in emulsions, stabilized by globular milk proteins, beta-lactoglobulin (BLG) or whey protein concentrate (WPC). First, we consider the effect of drop coalescence on the mean drop size, d32, during emulsification. Two regimes of emulsification, surfactant-rich (negligible drop coalesc...

An ultrasonic-solvent emulsification technique was adopted to prepare vinpocetine loaded Glyceryl monostearate (GMS) nanodispersions with narrow size distribution. To increase the lipid load the process was conducted at 50 degrees C, and in order to prepare nanoparticle using an ultrasonic-solvent emulsification technique. The mean particle size and droplet size distribution, drug loading capac...

The aim of the present study was to evaluate the stability of celecoxib (CXB) using novel nanoemulsion formulation. Optimized nanoemulsion formulation of CXB was prepared by low energy emulsification method. Stability studies were performed for the period of 3 months. Droplet size, viscosity and refractive index (RI) were determined during storage. Shelf life of nanoemulsion formulation was als...

The formulation, characterization, and anticipated antibacterial properties of hemp seed oil and its emulsions were investigated. The oil obtained from the seeds of Cannabis sativa L. in refined and unrefined form was characterized using iodine, saponification, acid values, and gas chromatography, and was employed for the preparation of stable oil-in-water emulsions. The emulsions were prepared...

The main purpose of the present investigation is to enhance the solubility and bioavailability of poorly watersoluble atorvastatin calcium (ATR) through the self nanoemulsifying drug delivery system (SNEDDS).The components for self-nanoemulsion were identified by solubility studies and tendency for self-emulsification in various excipients. Sefsol 218, Cremophor RH 40 and Propylene glycol were ...

Three new amphiphilic molecules were synthetized on a basis of common monomer, octadecyl succinic anhydride (OSA), which grafted different PEGylated hydrophilic polar head. The objective this study is to investigate potential relationship between the chemical structure surfactant, and efficiency generate nano-emulsions through spontaneous nano-emulsification method. Beyond innovative synthesis ...

Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene maleic anhydride copolymer (SMA), and the addition...
