RAFT non-aqueous emulsion polymerization of N-(2-acryloyloxy)ethyl pyrrolidone in n-dodecane using a poly(stearyl methacrylate) precursor is used to prepare sterically-stabilized nanoparticles, which are evaluated as putative Pickering emulsifier.

Colophonium (rosin, CAS no. 8050-09-7) is a complex mixture of >100 different compounds derived from pine trees. It is a good tackifier, can be used as an emulsifier, and has acid properties without causing corrosion. Because of these properties, colophonium is used in various products, such as soldering fluxes, paper, cosmetics (depilatory waxes, soaps, hair gel, and nail polish), cutting flui...

Turbulent flow of water in a short 0.4mm high micro-channel of an emulsifier is investigated experimentally using a micro-PIV technique and compared with numerical predictions. The micro-flow measurements are based on epi-fluorescence illumination and high-speed imaging. Velocity fields obtained from the measurements and direct numerical simulations indicate that flow turbulization is delayed a...

The kinetics of o/w electrostatically and sterically-stabilized microemulsion polymerization of styrene with and without macromonomeric azoinitiator (macroinimer; MIM) have been investigated. The microemulsion polymerization stabilized by the ionic emulsifier sodium dodecyl sulfate (SDS) or the non-ionic emulsifier Tween 20 (Tw 20) was initiated by ammonium peroxodisulfate (APS)/sodium thiosulf...

This paper presents a new method for fabrication of biodegradable polymeric nanoparticles as carriers for anticancer drug paclitaxel. Emulsion solvent evaporation method was frequently employed to prepare polymeric nanoparticles for drug delivery systems in which the emulsifier such as PVA has to be used. In this study, direct dialysis was employed to fabricate paclitaxel-loaded biodegradable p...

D-alpha-tocopheryl polyethylene glycol succinate (TPGS) has been utilized in numerous drug delivery formulations in recent years. Because of its amphiphilic structure, it can be used as emulsifier and vehicle for lipid-based drug delivery formulations. It is also an effective P-glycoprotein (P-gp) inhibitor. However, TPGS represents only one of the surfactants in the class of "Vitamin-PEG" conj...

In the prospecting and drilling processes of gas and oil, if added into the drilling fluids, the latex nanoparticles can improve the performance of the drilling fluids. In this paper, methyl methacrylate (MMA) acts as a monomer and the combination emulsifier is a certain proportion of OP-10, RH and T-80. PMMA latex nanoparticles have been polymerized through the method called microemulsion poly...

The increasing prevalence of obesity has emerged as one of the most important global public health issue. The change to the human microbiome as a result of changes in the quality and quantity of food intake over the past several decades has been implicated in the development of obesity and metabolic syndrome. We administered polysorbate-80 to mice via gavage. The researchers monitor liver nonin...

Lipid emulsion particles containing 10% of medium chain triglycerides were prepared using 2% w/w of a mixture 1:1 w/w of purified soya phosphatidylcholine and 2-hexanoyl phosphatidylcholine as emulsifier mixture, for use as drug carriers. The mean droplet sizes of emulsions, prepared using an Ultra Turrax or a high-pressure homogenizer, were about 288 and 158 nm, respectively, compared with 380...

ethoxylated fatty acids or polyoxyethylene esters of fatty acids possess surface active characteristic depending on ethoxylation degree (glycol type used).they have a wide range of applications and are known by formulated trade names.fatty acids used as starting materials are obtained by the hydrolysis of fats and oils and thus the final products are fully biodegradable.the objective of this in...
