No, denature and rubbing alcohol are different in terms of usage. Denatured alcohol is ethyl alcohol, which is toxic. This alcohol is safe to consume but it tastes bad. This agent works as a solvent and fuel additive. Therefore, it is used for finishing and sanding purposes. While on the other hand, rubbing alcohol is a minor cleaning solvent, and rubbing it can work as an antiseptic. Apart from this, rubbing alcohol is used for medical purposes. It is of surgical spirit rather than the methylated spirit. Rubbing alcohol is a type of denatured alcohol that is different from denatured one. However, it consists of 70 percent of ethanol in concentrated form.
