You can choose appropriate solvent from Solvent Miscibility Table using difference of the solvent's polarity index and miscibility.

Bruce Neagle

Ascorbyl Palmitate prefers an organic solvent and not water. See solubility tables for Palmitic Acid which is in fats and oils (like coconut oil).

Carlos Araújo Queiroz

Cf. (e.g.): J. Ji, "Chemical synthesis of ascorbyl palmitate in [BMIM]BF4", Advanced Materials Research, Vols. 236-238, 2011, 1962-1965.

Dr. Alwar Ramani

Hi Carlos

You can extract using water and de freeze under vacuum to get the compound.
