What is the maximum concentration that can be obtained in a liquid suspension?

Studies have indicated that topical vitamin c achieves it's most powerful effect at 20% concentration. Does anyone know what is the most powerful concentration of vitamin C that is possible to achieve in water and/or common solvents such as glycerin without the crystals precipitating out of the solution?

I highly doubt you will see anywhere near 20% in water. Your going to just have to do a bunch of googling.

However, vitamin C solubility is 330 g/L which means that 124 grams of vitamin C will dissolve into that same 1.5 cups of water.

From Preparation of Sodium Ascorbate (non acidic vitamin C) for IV and IM Use by Cathcart:

"It turns out that sodium ascorbate is soluble to almost exactly a 50% concentration at room temperature."
