We use the same ATF/TTB approved formula that everyone else is forced to use for heptane denatured ethanol, formula CDA12A. You will notice that the formula you are pointing out is in the SDA category rather than CDA.
Keep in mind that there are tons of denaturants, however, any that can be easily removed fall under SDA or specially denatured alcohol rather than CDA or completely denatured alcohol.
To buy, sell, or use an SDA both the vendor and customer must have licensing approving those uses. For example, we would need to be authorized to sell SDA and the client would need to be authorized to use SDA before we could sell it.
If anyone has a license to use SDA, we can get authorized to sell it in short orderâŚbut it would be a special sourcing arrangement rather than something we would keep in inventory.
