The Influence of Adding a Second Emulgent System on the Formulation - Assignment Example

When electrolytes are added, the effects could be profound, especially, on the physical stability the formulations have in the long run. Density modifiers can be used to ensure that the continuous and disperse phases have similar densities. This will prevent sedimentation and creaming problem.

Emulsions are thermodynamically unstable chemical compositions. As a result, care has to be taken to ensure that the physical stability remains intact. Other additives to formulations are colors, flavors, and perfumes. These additives have the capacity of altering emulsions; in terms of physical characteristics. This is because of the presence of electrolytes which have an effect on pH levels; and, therefore, can impact the flocculation degree. On the other hand, the addition of a sweetening emulgent leads to the exhibition of Newtonian properties. The consequence of this is that the rheological suspension properties could be affected adversely.

Emulsion viscosity is determined by emulsifying agent concentrations in the formulation preparations. This is applicable to both water-in-oil, in addition to, oil-in-water systems. From the table of results, we can see the effects that surfactants have on the stability of emulsions. In the different solutions, with varying degrees of surfactants, we can see that the changes through time depending on the concentration of the surfactants seen in B1, B2, A1, and A2.
