Approximate pH of selected cleaning products and other substances

Approximate pH of selected cleaning products and other substances
Note:
  • All pH values are approximate
  • Solvents do not have a pH, because they do not ionize in aqueous solution
  • pH does not measure the corrosiveness of an acid (ie, hydrochloric acid with a pH of 1 is stronger than phosphoric acid with a pH of 1)
* Hair relaxers may be made with lye (pH typically 12 to 14) or without lye (pH typically 9 to 11).
