The Commissioner may, if required for the analysis of antifreeze for the purposes of registration, require the applicant to furnish a statement of the formula of such antifreeze, unless the applicant can furnish other satisfactory evidence that such antifreeze is not adulterated or misbranded. Such statement need not include inhibitor or other minor ingredients which total less than five percent by weight of the antifreeze, and if over five percent, the composition of the inhibitor and such other ingredients may be given in generic terms. All statements, pertaining to the formula furnished under this section, shall be privileged and confidential and shall not be made public or open to the inspection of any person other than the Commissioner. No such statement shall be subject to subpoena nor shall the same be exhibited or disclosed before any agency or court by virtue of any order or subpoena of an agency or court unless with the consent of the applicant furnishing such statement to the Commissioner. Any person who violates the provisions of this section shall be deemed guilty of a misdemeanor and upon conviction shall be fined in an amount not to exceed fifty dollars for a first offense and in an amount not to exceed one hundred dollars for each subsequent offense.
