4. Conclusion
Table 3 qualitatively summarizes the structural effects of n-alcohol and fragrances on the PIT variation of the Brij30/octane/water system. The knowledge of these BC 11-38 patterns on emulsion behavior constitutes important information to design micro- and macroemulsions with desired properties for cosmetic, pharmaceutical and food industries.

The additive effect can have two interpretations on the HLD equation, a separated independent effect on f(A) or the modification of the EACN oil phase. Both of them can diminish the PIT and complete elucidation is uracil necessary to understand the phenomenological reasons of summarized changes on the PIT of Brij30/n-octane/water system. Effect of fragrances using a well-defined surfactant system and quantification of fragrances in different phases will be discussed in a forthcoming paper.
