Melting point: 300 \u00b0C. It is highly soluble in water, which makes it convenient for use in liquid and semi-liquid food products. In acidic environments (pH below 4.5), it is most effective as an antimicrobial agent, inhibiting the growth of yeasts, molds, and many bacteria.<\/p>\n<h2>Safety considerations<\/h2>\n<p>According to international safety classifications, sodium benzoate requires safety measures S24\/25 \u2014 avoid contact with skin and eyes when handling the pure substance. Some preliminary studies suggest that frequent exposure may stimulate allergic reactions. When combined with ascorbic acid (vitamin C) under certain conditions, sodium benzoate can form trace amounts of benzene, a known carcinogen \u2014 though the levels typically found in food products are considered very low.<\/p>\n<p>Find more information about <strong><a href=\"\/key-words\/food-additives\/\">food additives<\/a><\/strong> and preservatives in the articles below.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sodium benzoate is a food preservative classified under the international numbering system as E211.
