Read about emulsifiers here . As per @joe's comment you don't need to worry about an emulsifier if you are using your dressing soon after preparing, only if you plan to keep it longer. Personally I would go for flavor rather than storage time. However, the reference gives several choices for an emulsifier if you so choose.
According to Serious Eats, mayonnaise is even better! Honey or egg yolk work too. Whatever you do, use some kind of emulsifying agent. The same article shows the havoc a non-emulsified dressing will play on a perfectly innocent salad.
