What is an emulsion and what are emulsifiers?
*Emulsions help make a misture of oil and water.
*Emulsifiers make sure that the oil and water cannot separate out. Almost every creamy subsatnce, like ice cream, mayonnaise or milk, needs emulsifiers to be what it is.
*Emulsions are also used in cosmetics, face creams, lipsticks and lip gloss. There is emulsion paint for indoors, which is a water-based paint with oil droplets dispersed throughout.

Hydrophobic (scared of water) The tail is attracted to oil.
The tail is a long chain hydrocarbon
Hydrophilic (water-loving) The head is attracted to water.
The head of the molecule is a group of atoms with a charge.
