TOOTHPASTE COMPRISING FINE AND COARSE CALCIUM CARBONATE |
摘要 |
The present invention relates to a toothpaste which comprises particulate calcium carbonate as the main abrasive cleaning agent. By using a mixture of relatively fine particulate calcium carbonate with a certain level of relatively coarse particulate calcium carbonate, the toothpaste provides for a reduced RDA while maintaining the same cleaning efficacy in comparison with the use of only the relatively fine particulate calcium carbonate.
