The European Cosmetics Regulation (EC) 1223/2009 requires that all products manufactured for use in the EU must comply with the ISO 22716 Good Manufacturing Practices (GMP) standard. The GMP guidelines state that water used as a cosmetic ingredient should be of a defined quality and that this should be maintained through regular testing or monitoring of the water.
