This mixture (oil/AVK) was treated as if it was only one component in the diagram, which has three components in its vertices: oil/AVK, water and n-propanol. Second, the points inside the triangle were plotted, as follows: fixing the quantity of one component and varying the others (the variations were 5% for each). The procedure ended when the whole interior of the diagram was plotted. Each point represents a mixture and, therefore, it must have its proper physical characteristics (emulsified or transparent mixture) identified for further delineation of the different regions. Fig. 1 shows two distinct regions: region I, where a homogeneous and transparent solution is found, and region II, where mixtures form an emulsion.
