What it does: emulsifying, surfactant/cleansing 

The science

Polysorbate 20 is a common ingredient that, as a dispersant, helps water and oil to mix together. It can help to increase the solubility of some other ingredients in the formula and acts as a nonionic surfactant and wetting agent that enhances the spreadability of liquids, making the application process easier.

It is a thickener as well as a viscosity modifier, thus helping prevent changes to a product’s viscosity when it is subjected to varying room temperatures, such as extreme cold or heat.
