Here's a technology I had never heard about, dry water. It sounds fascinating and could result in the creation of truly surfactant free cosmetic products.
What is dry water?
Dry water is essentially a water/air emulsion in which a dry, hydrophobic powder is used to coat droplets of water. It was first patented in 1968 then re-discovered in 2001 in the form of liquid marbles. The technology seems pretty cool. Take a look at this video for a demonstration. There is a powder covering the top of the water so when the experimenter pokes their finger through the surface, it doesn't get wet.https://www.youtube.com/watch?v=wt1TfPuTzq0
While it seems pretty cool, I'm still trying to figure out how this could be used in a cosmetic product. Perhaps you could coat aqueous solutions of humectants or maybe even a liquid marble of emulsion particles. I wonder if that would work.

Anyway, it seems like pretty interesting technology. It's definitely a technology I haven't seen extensively applied to cosmetics. This could be an innovative avenue for a crafty formulator to follow.
