The oil and aqueous phase
was placed in a container and then blended for 2 minutes using a high shear mixer (M133/1281-0, Biospec Products Inc.
As in the later case, meloxicam is solubilized in the outer layer and the loss of drug to the aqueous phase
with which it comes into contact during the production process of nanopartidies can be facilitated.
The compositions of organic and aqueous phases
were varied by adding emulsifier (Monoglyceride), sodium chloride and thickening agent (mango's pulp).
Therefore, effects of the composition related to polymers and organic solvents in the oily phase, molecular weights and thiol amounts of chitosan in the aqueous phase
, and surfactants as well were investigated in this study.
5 shows the variation of recovery of estrogens with the increase of the pH value of the aqueous phase
in solvent extraction.
Of course, if one makes the assumption that the concentration of monomer(s) in the aqueous phase
remains constant (i.
The addition of proteins/polysaccharides may increase the viscosity of aqueous phase
which can lead to increase the quality and stability O/W emulsion [13, 14].
The best chromatography was attained using a mobile phase composition of 50-50 split of methanol as organic phase and 5 mM oxalic acid solution as aqueous phase
flowing at 0.
The volume of the aqueous phase
was increased to 20 mL using distilled water.
The typically low systemic bioavailability of the lipophilic curcumin is attributed to its poor solubility in the aqueous phase
of the digestive tract and its rapid metabolism and excretion from the body.
Arne Dugstad: If an aqueous phase
is formed, several competing corrosion mechanisms can be foreseen, depending on the type of impurities that are dissolved in the water phase and the type of cross-chemical reactions (bulk phase reactions) taking place.
These could be interpreted using the kinetic model of the pseudophase proposed by Menger and Portnoy , which, taking the micelles as a pseudophase uniformly distributed in the aqueous phase
, put forward a reaction scheme with a micelle-substrate equilibrium governed by an equilibrium constant [K.
