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.
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.
