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.
Is calcium propionate bad for you?
No—at permitted food levels, calcium propionate (E282) is considered safe by regulators (FDA GRAS; EU-approved) and is rapidly metabolized. A small number of people may be sensitive, but evidence of harm at typical dietary exposures is limited.
What is calcium propionate made from?
It’s the calcium salt of propionic acid, usually produced by neutralizing propionic acid with calcium hydroxide or calcium carbonate. The propionic acid can come from petrochemical synthesis or fermentation by Propionibacterium.
Is calcium propionate banned in europe?
No—E282 is authorized in the EU as a preservative in specified foods under Regulation (EC) No 1333/2008, with set maximum levels. It is not permitted in foods for infants and young children.
What is calcium propionate used for?
It’s a preservative that inhibits molds and some bacteria to extend shelf life. In baking, it helps prevent mold and “rope” spoilage in bread and similar products.
What is calcium propionate used in?
Commonly in bread, rolls, tortillas, cakes, and other baked goods; it’s also permitted in some processed cheeses depending on the jurisdiction. Specific uses and limits vary by country and product category.
