What-it-does: emulsifying


A waxy solid material that helps oil and water to mix together, aka emulsifier. It is super similar to Steareth-20 with just a little more ethoxylation and thus a little more water solubility. It works very well when combined with mostly oil-soluble emulsifiers such as Steareth-2 and the two together can form exceptionally stable emulsions. 

Products with Steareth-21
