Better is Acetic acid

Water itself is also fine. In space what ocurres with water? Does it freeze or evaporate?

Depends on temperature and pressure. This diagram doesn't go that low, but I would guess it's a solid in the near vacuum of space based on what I know of space ice like Saturns rings and comet tails.
Yes, Water itself has a pretty weird freezing diagram, but meltin diagrams are already weird, even in metals as I remeber this from Iron, iron carbid. Melting always depends on several factors, pressure, depending of added substances...

That's a phase diagram, there's probably lots of cool things going on in the solid state below that line. Probably different ratio solids at each peak. 1:4 3:2 etc. The % are goofy because it is reported by weight but behaves based on count.
