Is Benzoic Acid Polar or Nonpolar?

Benzoic acid is a colorless crystalline solid with a chemical formula of C6H5COOH In most cases polar compounds are soluble in polar solvents like water but benzoic acid is a unique exception Because of its large hydrophobic benzene ring benzoic acid is only slightly soluble in water when heated Benzoic acid can be made soluble however

The relationship of pKa and acute skin irritation in man

The relationship between pKa and skin irritation in man is studied for a homologous series of benzoic acid derivatives which permeate through human skin at comparable rates (15-88 micrograms/cm2/hr) Skin irritation and pKa are correlated for pKa less than or equal to 4
