Completely Denatured Alcohol (CDA 12A-1) is simply a blend between two different chemicals.  The Starting product is 200 proof ethanol blended with 5% high-purity n-Heptane. 

Denatured alcohol is just alcohol with ingredients added to make it toxic to human consumption.

CDA 12A-1 is primarily used for laboratory and research use. It is becoming more and more popular as a process solvent for various pharmaceutical and botanical purposes. In the cannabis and hemp industries, CDA 12A-1 is used in ethanol extraction to remove the oil-based cannabinoids from the plant.

Given CDA 12A-1 is not meant for human consumption, regulations are reduced.  CDA 12A-1 incurs no federal excise tax, does not require any permits to buy or store, does not have storage limits imposed by the Tobacco and Trade Bureau (TTB), and does not require record-keeping with the TTB.

 CDA 12A-1 has recently grown in popularity due to the boom in the cannabis and hemp industries. The hemp and cannabis extracts are produced for consumer packaged goods like CBD gummiesCBD oil drops & tincturesCBD skincare & topicals.

CDA 12A-1 is a great option to save time, money, and hassle. It is a notable alternative to pure ethanol for specific pharmaceutical uses along with botanical extraction. There is a rising demand for CDA 12A-1 hydrocarbons due to the growing use of hemp and cannabis.
