In the global trading of raw materials, the choice between extra neutral alcohol (ENA) and anhydrous ethanol is not just a technicality. It is the difference between a perfect product and a costly batch failure. But what is the difference between anhydrous ethanol and extra neutral alcohol? Read our full breakdown of ENA vs anhydrous ethanol in this blog post.
Extra neutral alcohol, also known as ENA, is a high-purity ethanol containing at least 96% alcohol by volume (ABV). The final liquid of neutral alcohol is clear, colourless, and free from any secondary smells or tastes that could interfere with your final product.
Extra neutral alcohol is derived from raw materials such as sugarcane, molasses, and grains like corn, rye, wheat, barley and rice. It is a commonly used food-grade alcohol. Denatured ethanol is popular in industrial/pharma processing.
When deciding if extra neutral alcohol is suitable for your processes, consider the pros and cons of it.
Extra neutral alcohol is safe when handled according to its hazard class (flammable liquid). Always refer to the safety data sheet regarding inhalation risks and fire safety, as it is a highly volatile liquid.
Anhydrous ethanol is a high-grade alcohol that has had virtually all water removed, typically reaching a purity of 99.5% or higher, with very low water content (≤0.5%).
Anhydrous literally means ‘containing no water’. It is also known under the names absolute alcohol, 200 proof ethanol, or 99 ethanol alcohol.

Technically, absolute alcohol is as close to 100% as industrially possible, but it is rarely a perfect 100.00%. This is because anhydrous ethanol readily absorbs water from the air as soon as the container is opened. Even the highest-grade water-free ethanol will pull moisture from the atmosphere until it reaches a stable equilibrium.
In many industrial applications, even a small amount of water can ruin a mixture or cause a dangerous reaction. This is where anhydrous ethanol becomes essential for ensuring reliable performance.
Consider the advantages and disadvantages of anhydrous ethanol to determine its suitability for your processes.
Like all concentrated chemicals, anhydrous ethanol carries risks. It is a high-risk hazard class due to its flammability. Furthermore, many industrial anhydrous grades are denatured, so they are strictly not for human consumption.
The primary difference between anhydrous ethanol and extra neutral alcohol lies in their water content and the method used to produce them.
