Well, on the pH scale, its acidity level is at 3. Meaning, its not a very harmful acid. But it will sting if it gets in your eyes or in a cut.
Soapmakers measure the acidity or alkalinity of bath soap by its pH level on a scale of 0 (acidic) to 14 (alkaline). Substances at either end of the scale, such as sulfuric acid and lye, are harmful to skin.
