  • Field of application and/or use : (a) Toothpastes (b) Mouthwashes
  • Maximum concentration permitted at final product : 0.15% expressed as fluorine. When it is mixed with other fluorine compounds permitted, the maximum concentration fluoride total must not exceed 0.15%
  • Use conditions and warnings that must appear on the label : a) - Contains calcium fluoride. For toothpaste containing 0.1% -0.15% fluoride, except if is already included that is contraindicated for children (e.g. “for adult use only”) it must contain the following warning: “Children under 6 years: Use an amount like a pea size, with adult supervision during brushing to minimize swallowing. If you ingest fluoride from other sources, consult your doctor or dentist" b) - Contains calcium fluoride. - Keep out of children reach. - Do not use in children under 6 years old.
