Abstract
The astringency of an oral composition containing biologically active zinc ions may be reduced by the addition of glycine to the composition, and adjustment of the pH to about 4.5 to 9.4. In addition, zinc may be kept in a biologically active solution at this pH by the addition of glycine. The zinc-glycine combination serves as an anticalculus-antiplaque-antimalodor agent in oral compositions.
