Prevention of crystal formation in toothpaste |
摘要 |
In dentifrices containing sodium bicarbonate and anionic species which can react with sodium and water to precipitate hydrated crystals, the ratio of water to humectants, abrasives, and/or thickeners is adjusted so that the dentifrice has a water activity of no greater than 0.60 so as to greatly reduce the salting out of the anionic species.
