Abstract
Oral compositions containing a water-insoluble noncationic bactericide showing improved stability with time and improved rheologic properties, and exerting excellent effects of eliminating dental plaque, preventing halitosis and eliminating tooth-staining substances. Addition of porous calcium carbonate to the oral compositions makes it possible to prevent the decrease in the bactericidal activity of water-insoluble noncationic bactericides such as triclosan and improve the stability thereof while exerting excellent effects of eliminating dental plaque, preventing halitosis and eliminating tooth-staining substances. Furthermore, addition of sodium carboxymethyl cellulose to the oral compositions makes it possible to improve rheologic properties and stability with time.
