Overview

E210 - Benzoic acid

Benzoic acid (E210) is a preservative used to help keep acidic foods and drinks safe and fresh by slowing the growth of yeasts, molds, and some bacteria. It occurs naturally in small amounts in some berries and fermented foods, and is also made for food use under strict purity standards.

E905 - Synthetic wax

Synthetic wax (E905) is a highly refined, petroleum‑derived wax used in tiny amounts to give foods a smooth, glossy finish or to keep them from sticking. It shows up most often on the outside of confections and in chewing gum coatings, and it is regulated with strict purity and use limits in both the U.S. and the EU. It does not add flavor or nutrition; it’s there to protect texture and appearance.

Popular questions

Is benzoic acid soluble in water?
Only sparingly—about 3 g per liter at room temperature; its solubility increases in hot water and it dissolves readily in many organic solvents.
Is benzoic acid polar?
It has a polar carboxyl group but a nonpolar aromatic ring, so overall it’s only weakly polar; its benzoate salt is much more polar and water‑soluble.
Is benzoic acid a strong acid?
No—it's a weak acid, with a pKa of about 4.2.
What is the melting point of benzoic acid?
About 122–123 °C (251–253 °F).
Is benzoic acid bad for you?
At approved food levels it’s considered safe, with an ADI of 0–5 mg/kg body weight/day; some people may experience irritation or hypersensitivity, and benzene formation in certain acidic drinks is monitored and kept very low.
