Tartaric acid and its salts are hydrophilic (i.e. they show high polarity).
A collection of the partition coefficients was performed for tartaric
acid and its salts (i.e. monosodium, monopotassium, sodium potassium,
sodium, potassium and calcium tartrate). As result, some values
specifically referred to tartaric acid were found. These values were
similar and support the hydrophilicity of the substance (i.e. all LogKow
were < 0). Since the partition coefficient of tartaric acid is extremely
low and taking into account the chemistry of its salts (i.e. their water
solubility), it is believed that also the tartaric acid salts should not
