Denaturants

Denaturants are essential additives in the ethanol industry. By incorporating specific chemicals into ethanol for industrial use, denaturants impart unpleasant tastes, odors, or toxic properties, transforming it into "denatured ethanol." This ensures compliance with regulations, helps prevent misuse or accidental ingestion, and lets you avoid high tax payments put on by governments for food-grade alcohol. Common denaturing agents include methanol, isopropyl alcohol, denatonium benzoate, and methyl ethyl ketone, each chosen for their effectiveness and availability. At Nedstar, we offer ethanol that can be denatured with the following chemicals:

Isopropyl (IPA) is a colourless, flammable chemical compound with a strong odour. It is used in the manufacture of a wide variety of industrial and household chemicals like handsanitizer or cleaning.

Diethyl phthalate (DEP) is a phthalate ester. It occurs as a colourless liquid without significant odour but has a bitter, disagreeable taste.

Tertiary butyl alcohol (TBA) is the simplest tertiary alcohol. It's a solvent, ethanol denaturant, paint remover ingredient, oxygenate but also widely used in cosmetics.

Bitrex, also known as denatonium benzoate, is the most bitter chemical compound known, with bitterness thresholds of 0.05 ppm, where 10 ppm is unbearably bitter for most humans.
