1. Presentation of emulsions
Emulsions are ubiquitous in the world of formulation.
They can be found in a number of important industrial fields, such as energy (Aquazole ® , a water/diesel emulsion that is less polluting than traditional diesel fuels; Orimulsion ® , a crude oil/water emulsion that enables highly viscous oil to be transported by pipeline and used as a liquid fuel), food (salad dressing, butter, mayonnaise, ice cream), cosmetics (moisturizing cream, body lotion, sun cream), agrochemicals (self-emulsifying concentrate), polymers (emulsion polymerization, latex) or aqueous paints (water-dilutable).
In all these applications, it is essential to control the nature of the emulsion's continuous phase, as this is what governs, to a large extent, the application performance...

Emulsifying an epoxy resin
For the past decade, water-emulsified resins have been replacing resins dissolved in volatile organic solvents. This is the case for epoxy resins, which cannot easily be prepared in latex form by emulsion polymerization. Epoxy-bisphenol A resins have a high viscosity (100 Pa · s at 70 ˚C) which makes it virtually impossible to emulsify them in water by means of strong agitation. As with alkyd, polyurethane or...
