Abstract Vitamin D 3 and iron are important components of a balanced diet. Supplementing meals with these is essential to support the recovery humankind’s malnutrition. It necessary develop effective delivery systems ensure high bioavailability hydrophobic components. For this purpose, emulsions were prepared based on hemp seed oil soap nut extract ( Sapindus mukorossi fruits) as natural emulsi...

Non-derivatised cellulose is generally assumed to have poor surface activity and therefore be unsuitable as a water in oil (W/O) emulsifier. In this work, “natural” microgel (CMG) fabricated via top-down approach used stabilize W/O emulsions, without employing chemical modification. The coagulated from an ionic liquid through solvent-exchange process, the presence absence of added sunflower oil...

Acinetobacter calcoaceticus BD4 and BD413 produce extracellular emulsifying agents when grown on 2% ethanol medium. For emulsifying activity, both polysaccharide and protein fractions were required, as demonstrated by selective digestion of the polysaccharide with a specific bacteriophage-borne polysaccharide depolymerase, deproteinization of the extracellular emulsifying complex with hot pheno...

A poly(ethylene glycol) (PEG) based macroinitiator (MI) with terminal chloride atom at both ends was prepared by the reaction of PEG-400 with chloroacetyl chloride and used for the cationic polymerization of dodecyl vinyl ether (DVE) yielding ABA type block copolymer. The block copolymer was then used as the surfactant for the emulsion polymerization of vinyl acetate and styrene in the presence...

Nanocomposites of a polymer and carbon nanotubes exhibit high electrical and thermal conductivity and enhanced mechanical properties in comparison to the polymer alone. Film formation from latex dispersions is an ideal way to create nanocomposite coatings with the advantages of solvent-free processing and a high uniformity of dispersion. It is shown here that carbon nanotubes functionalised wit...

Sir, Picaridin, a piperidine derivate, is a promising insect repellent that has been available to the consumer since 1998 (1). Picaridin protects against arthropods in a similar fashion to diethyl toluamide (deet), which is considered the gold standard compound (2, 3). Picaridin is also better tolerated than deet (1, 4), a fact that has encouraged its use in repellent formulations. We describe ...

Investigations were started to develop methods for isolating beneficial polyphenols from hops. As a result two new types of extracts were developed. One is mainly consisting of prenylflavonoids (main ingredient is xanthohumol). This product is not soluble in water but in ethanol. The other extract is water soluble and rich in glycosidically bound polyphenols (multifidol, quercetin, kaempferol)....
