Emulsifiers/Co emulsifiers
Emulsions are systems composed of two or more immiscible materials. The immiscible phases can be water, oil, or silicone.
Emulsions type are:
– O/W stands for oil-in-water and is classified as an emulsion.
– W/O stands for water-in-oil and is classified as an invert emulsion.
– These types of emulsions are much more difficult to stabilize than oil-in-water systems.
-They also must have much smaller droplets to help them stay together longer.

Emulsifiers/Co emulsifiers are ingredients used in cosmetics to help mix substances that usually don’t blend well like oils and water. Emulsifiers work by reducing the tension between liquids that don’t dissolve in each other. They allow the liquids to mix together and stay mixed, rather than separate.
Emulsifiers can be classified into different categories based on various criteria:
1-Ionic nature
2- Chemical composition
3- Emulsion Type
4-Hudrophilic- Lipophilic Balance(HLB)
5- Origin
6- Physical state
