What is it?

Specially denatured (SD) alcohol is a mixture of ethanol with a denaturing agent. A denaturing agent makes the alcohol (ethanol, ethyl alcohol) unfit for consumption as a beverage by the addition of one or several chemicals for commercial purposes (methanol, aldehol, sucrose octa-acetate). Ethanol is linked to birth defects following excessive oral ingestion. Potential risks from ethanol in personal care products are significantly smaller than the health risks posed by the consumption of alcohol.[1][2] Denatured alcohol may be used in pharmaceutical manufacturing, but in small amounts if contained in oral dosage forms.[1][2]
