Abstract
The present invention relates to an oral composition such as a dentifrice. It has been found that the stability of a monofluorophosphate and a soluble zinc compound such as zinc citrate is improved in a dentifrice if instead of milled alumina trihydrate abrasive an unmilled precipitated alumina trihydrate abrasive is used in the dentifrice.
