Ethoxydiglycol

What-it-does: solvent

It’s a nice odorless liquid that is used most often as a great solvent for some active ingredients, like vitamin C. 

Other than that it can also be used in hair care products where it gives a longer-lasting and more uniform coloring. According to a manufacturer it even prevents the formation of split ends though we have to admit we are sceptical about that.
