                  • At >85%, viscosity becomes very high, making handling and storage difficult<\/li>\n
                  • Higher concentrations are prone to polymerization, crystallization, or gel formation, undesirable in food use<\/li>\n
                  • Higher corrosiveness at >85% complicates safe dosing in foods<\/li>\n
                  • 85% balances purity, usability, and safety<\/li>\n<\/ul>\n
