Emulsified sauces are emulsions; mixtures of liquids that ordinarily  
don't want to mix, like oil and water, say, which, when mixed  
properly, thicken due to surface electrostatic charges on droplets.

Emulsions / emulsified sauces include thick vinaigrettes, some honey  
mustards with some oil beaten into them to lighten their texture and  
flavor, mayonnaise, Miracle Whip, Hollandaise Sauce, Bearnaise Sauce,  
Beurre Blanc, Beurre Rouge, and even properly melted chocolate.

Roux is a preparation, almost a verb. There is no plural, except as  
multiple examples of the technique. It's kind of like, what's the  
plural of photography? You can have more than one batch of roux, or  
more than one use, but roux is roux.

More simply, the plural of roux is roux.
