Why we only use undenatured alcohol
Quality and safety are of the utmost importance at CRS, which is why we are one of the few manufacturers permitted to acquire 99,99% ethanol. All products are manufactured exclusively with undenatured alcohol. This means that we start with the purest base ingredient, giving you the safest, most effective sanitising product.

Undenatured ethanol is the pure form of ethanol that contains no or fewer additives and denaturants. There are two forms of undenatured ethanol named 95% ethanol and absolute ethanol. These forms are known as “pure” forms of ethanol.
Absolute ethanol is a purer form than any other form of ethanol. That is because it contains 99-100% ethanol. This form of ethanol is very useful in laboratory techniques that are very sensitive to the presence of water. To obtain absolute ethanol via distillation, additives are used during the distillation process. These additives can break down the azeotrope state of ethanol and allow more ethanol to be distilled. Therefore the absolute ethanol may contain some additives such as benzene but in trace amounts.
Denatured ethanol is a form of ethanol containing a high amount of additives and denaturants that makes it poisonous. Denatured ethanol has bad taste and foul smell that makes it unsafe for drinking. Sometimes it is also added with some dyes to distinguish denatured ethanol from undenatured ethanol. The process of denaturing ethanol does not alter the chemical structure of ethanol or decompose it. Ethanol is only altered to make ethanol undrinkable.
The additives that can be found in denatured ethanol are methanol, isopropanol, pyridine, etc. These are added to get the poisonous ethanol and sometimes denatonium is used to make the ethanol bitter. The purpose of producing denatured ethanol is to reduce recreational consumption and to reduce taxes on alcoholic beverages. The traditional additive used for denaturing ethanol is 10% methanol. Denatured ethanol is cheaper than undenatured forms of ethanol.
