Abstract
The invention relates to oral compositions such as toothpastes which contain Vitamin C and a copper compound such as coppersulphate. The tendency of these compositions to discolour, particularly if they also contain a zinc compound such as zinc citrate, can be reduced by the inclusion in the compositions of a stannous compound such as stannouspyrophosphate.
