Surfer 13 Ternary Contour Plot Kummessenger Pseudo ternary phase diagram with tween 80 (t 80) and kolliphor® el (el) as surfactants (s), transcutol® p (tp) and peg 400 as co surfactants (cos), and ethyl oleate (eo) as the oil phase (oil. Pseudo ternary phase diagrams were constructed for three different surfactant ratios: (a) 1:1, (b) 1:2 and (c) 2:1 (span 80:tween 80). within the s mix 1:1 pseudo ternary phase diagram, each black marker represents the formulations evaluated for stability. the numbered markers are those that proved to be stable for the duration of the study.
Pseudo Ternary Phase Diagram Patel Et Al 2014a Factors Affecting Pseudo ternary phase diagram with tween 80 (t 80) and kolliphor ® el (el) as surfactants (s), transcutol ® p (tp) and peg 400 as co surfactants (cos), and ethyl oleate (eo) as the oil phase (oil). km is the mass ratio of the surfactant to co surfactant, and the shaded area in the diagram is the oil in water (o w) microemulsion region. From the pseudo ternary phase diagram, polysorbate 80, and cetiol® he at a ratio of 1:2 showed the largest microemulsion area. the amount of the loaded grape seed oil and surfactant mixtures were. Typical pseudo ternary phase diagrams using tween 80 as the surfactant are shown in figure 1. the translucent and low viscosity microemulsion area was designated as the microemul sion (me) area. For example, a study demonstrated the use of a pseudo ternary phase diagram to optimize a formulation containing oleic acid as the oil phase, tween 80 as the surfactant, and peg 400 as the co surfactant. the resulting phase diagram indicated a significant self emulsifying region, which facilitated the selection of optimal ratios.
Pseudo Ternary Phase Diagrams For Microemulsions Pseudo Ternary Pha Typical pseudo ternary phase diagrams using tween 80 as the surfactant are shown in figure 1. the translucent and low viscosity microemulsion area was designated as the microemul sion (me) area. For example, a study demonstrated the use of a pseudo ternary phase diagram to optimize a formulation containing oleic acid as the oil phase, tween 80 as the surfactant, and peg 400 as the co surfactant. the resulting phase diagram indicated a significant self emulsifying region, which facilitated the selection of optimal ratios. The phase diagram of the system containing castor oil, tween ® 80, and plurol ® diisostearique is shown in figure 2a. as seen from the pseudo ternary phase diagram, these combinations produced a reasonably wide self emulsification region. fine spontaneous emulsions did not efficiently form when the concentration of the surfactant was less. In order to determine the concentration range of components for the lc mes, pseudo ternary phase diagrams were constructed using the aqueous titration method that includes stepwise addition of water to each weight ratio of oil and surfactants followed by mixing of the components with the help of vortex at 25 °c (moreno et al., 2003, naz and ahmad, 2015).
