- olivier_martel 8y agoprobably by heating or crushing the powder.
- s0rce 8y agoYou could distill it off just like you distill normal water. Lowering the surface energy might also be a possibility. Might be able to introduce a powdered surfactant and then mix a bunch. Should then wet everything and you can sediment out the solids.
- kccqzy 8y agoI'm guessing but, boil it and condense? I'm guessing that the great increase in volume when reaching the boiling point is enough to rupture or destroy the coating.
- Rexxar 8y agoMy first guess would be to add more water.
- saudioger 8y agoDry water in cosmetics just takes a little compression — you rub it on your skin and you get the liquid within and some insubstantial amount of byproduct from the coating the liquid was stored in. Also, the coating is gas permeable, so you could boil the liquid out.
