Creating Chemically Dissimilar Liquids

Dissimilar chemical compositions prevent the different in an emulsion from ever mixing on their own. For example, fats are hydrophobic, which sounds like they don't like swimming in water which is exactly the case. If you put fats in water, they will avoid mixing with it. Fats just don't have the right chemistry to mix with water because water is __polar__, which means water molecules contain both positively charged and negatively charged atoms. Any molecule or atom that is polar, positively charged, or negatively charged will dissolve in water because the electrical charges attracted to the electrical charges in the water molecule. Fats are non-polar molecules, which means they do not have an electrical charge and won’t mix with water because there are no charged atoms that attract them to water molecules.
Liquids in emulsions will eventually separate and form layers unless something prevents them from separating.
An __emulsifier__ is similar to glue because they can make chemically dissimilar liquids stick together and prevent them from separating. Emulsifiers are able to help chemically different liquids mix because they can interact with both polar and non-polar liquids because they have parts that are charged and parts that are not charged. Shampoos, soaps and detergents are examples of emulsifiers. The reason why they can clean things is because they prevent oil and water from separating so that the oil gets washed away with
water.
