§ 184.1021 Benzoic acid.
（a） Benzoic acid is the chemical benzenecarboxylic acid （C7H6O2）, occurring in nature in free and combined forms. Among the foods in which benzoic acid occurs naturally are cranberries, prunes, plums, cinnamon, ripe cloves, and most berries. Benzoic acid is manufactured by treating molten phthalic anhydride with steam in the presence of a zinc oxide catalyst, by the hydrolysis of benzotrichloride, or by the oxidation of toluene with nitric acid or sodium bichromate or with air in the presence of a transition metal salt catalyst.
（b） The ingredient meets the specifications of the “Food Chemicals Codex,” 3d Ed. （1981）, p. 35, which is incorporated by reference.

（c） The ingredient is used as an antimicrobial agent as defined in §170.3（o）（2） of this chapter, and as a flavoring agent and adjuvant as defined in §170.3（o）（12） of this chapter.
（d） The ingredient is used in food at levels not to exceed good manufacturing practice. Current usage results in a maximum level of 0.1 percent in food. （The Food and Drug Administration has not determined whether significantly different conditions of use would be GRAS）.
（e） Prior sanctions for this ingredient different from those uses established in this section, or different from that set forth in part 181 of this chapter, do not exist or have been waived.
