Formula may be required.

The department may, if required for the analysis of antifreeze by the department, 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 5 percent by weight of the antifreeze; and, if over 5 percent, the composition of the inhibitor and such other ingredients may be given in generic terms.
