Formulation process emulsions

The same process was applied with the griseofulvin solubilized in the organic phase for the formulation of emulsions loaded with griseofulvin. Different loadings of griseofulvin could be easily checked. 

To summarize, it should be evident that particle size, particle size distribution and particle shape can, and very likely do, enter into consideration in all aspects. of emulsion polymerization from synthesis through formulation, processing and finally end-use performance. 

In early reports on the formation of double emulsions only one set of emulsifiers and an inversion process were used. Such preparations were done in one step, but the stability was in most cases questionable. It was difficult to control the distribution of the emulsifiers within the two interfaces. There was fast migration of the emulsifiers between the phases that destabilized the emulsions. In most recent emulsion formulations the emulsions are prepared in two steps. At first, a high-shear homogenization is applied to the water that is added to the solution of the oil and the hydrophobic emulsifiers, to obtain a stable W/0 emulsion. In the second step the W/0 emulsion is gently added with stirring (not homogenization) to the water and hydrophilic emulsifiers solution (Fig. 2). The droplet size distribution of a typical classical double emulsion ranges from 10 to 50 pm.

Petroleum emulsions have been used to prevent the formation of foams, or destroy foams already generated, in various industrial processes [155], The rapid spreading of drops of low surface tension oil over lamellae ruptures them by providing weak spots [J56]. Polydimethyl-siloxanes are frequently used as practical antifoaming agents because they are insoluble in aqueous media (and some oils), have low surfaee tension and are not overly volatile. They are usually formulated as emulsions for aqueous foam inhibiting so that they will readily heeome mixed with the aqueous phase of the foam. A review of refinery foam oeeurrenees and treatment is given hy Lewis and Minyard [157].
