pw] are phenol concentrations respectively in the bulk and at the interfacial area of the aqueous phase, mol [m.
A second way in which the hydrophobic segments on a surfactant molecule can isolate themselves from the aqueous phase is to adsorb at a pigment surface.
m is partition coefficient of Zinc between aqueous phase and organic phase.
In the release experiments, the concentration of phenol in the aqueous phase was kept at conditions approximating an infinite sink.
SL], so that the aqueous phase can more effectively wet out the pigment particles.
One would envisage colorant stabilization through the surface adsorption of the PPO units with the PEO segments soluble in the aqueous phase, providing the steric or osmotic stabilization against flocculation, and optimizing color development.
Ted Russin, Scientist, describes the basic principle behind this invention: "Through a density gradient, created by blending fat-based emulsifiers, an aqueous phase with KELCOGEL([R]) F gellan gum and incorporated air, we can create a homogenous stream that rapidly separates into different phases and eventually sets into a layered gelled dessert.
25% levels in warm anhydrous milk fat that was subsequently emulsified at 10% levels into a neutral aqueous phase, which contained 1% whey protein isolate or sodium caseinate.
High viscosity and density of EVO, small density difference between oil and water, a high degree of the aqueous phase dispersion, high content of resins and asphaltenes in the oil, which are natural stabilizers, make the EVO emulsion highly resistant to destruction.
