One part of the molecule (tail) is a long hydrocarbon that can’t dissolve in water but in oil. Hence it’s hydrophobic. The other part (head) has an electric charge which can’t dissolve in oil but in water. Hence it’s hydrophilic. The molecule liquefies its tail in the oil droplets and head in water. More emulsifier molecule use to maintain dispersed of oil droplet in water for more time. (gcsescience.com, 2015)
Egg is widely used emulsifier. Some behave like anti-caking agents such as Magnesium stearate, potassium, sodium, calcium salts. To make the compatible of the two components these are used.
