SCIENCE Chloe Viceral Zhidnih Tiocao Caillan Juliane Charlize Aban Lim In mayonnaise the egg yolk is used, inside it has a chemical called lecithin this is a natural emulsifier an emulsifier is something that basically prevents two liquids from separating eg, water and oil. in mayonnaise the main substances are vinegar and oil and egg yolk. when you add the egg yolk to the vinegar and the oil it becomes something called an emulsion. emulsion is droplets of one liquid suspended into another. so if you didnt have egg in the mayonnaise, it wouldnt be mayonaise, it would just be vinegar with oil floating on top of it. The short version: they help the water and oil to mix.
