Process for preparing standard synthetic water-in-oil emulsions and said emulsions

A process for preparing water-in-oil emulsions, wherein the process comprises:

• (i) defining one or more water:oil proportions in the emulsion, based on the interest of applying the standard emulsion;
• and
• (ii) defining the composition/salinity of the aqueous phase and the type of oil to be used;
• based on information (i) and (ii) above:
• (iii) choosing the hydrophilic-lipophilic balance (HLB) of interest for the standard emulsion and one or more surfactants to be used;
• (iv) dissolving one or more specific surfactants for each phase of interest,
• wherein the dissolution occurs according to the affinity between the phases, considering the proportions found from the HLB calculation;
• (v) mixing the phases;
• and
• (vi) homogenization.
