(2) The gibberellic acid produced is of 80 percent purity or better.
(3) The empirical formula of gibberellic acid is represented by C19 H22 O6.
(4) Potassium gibberellate is the potassium salt of the specified gibberellic acid.

(c) To insure the safe use of the food additives the label of the package shall bear, in addition to the other information required by the Act:
(1) The name of the additive, “gibberellic acid” or “potassium gibberellate”, whichever is appropriate.
(2) An accurate statement of the concentration of the additive contained in the package.
(3) Adequate use directions to provide not more than 2 parts per million of gibberellic acid in the finished malt.
(4) Adequate labeling directions to provide that the final malt is properly labeled as described in paragraph (d) of this section.
(d) To insure the safe use of the additive the label of the treated malt shall bear, in addition to the other information required by the Act, the statements:
