1, preservative: molecular benzoic acid has a strong antibacterial effect, so the antibacterial effect is good in acidic solution, the optimal pH is 4, with the increase of solution pH, the degree of dissociation increases, the anti-corrosion effect decreases. The preservative effect of benzoic acid is weaker than that of hydroxyphenyl ester, but the anti-fermentation effect is stronger than that of hydroxyphenyl ester. The combination is ideal for preventing fermentation and mildew, especially for liquid preparations. The antiseptic mechanism of sodium benzoate was the same as that of Benzoic acid, and the antiseptic effect of sodium benzoate 1.18g was similar to that of Benzoic acid 1.0g.
