ABSTRACT:
Precipitated silica product having low surface area and enhanced flavor compatibility. The precipitated silica product is especially well-adapted for use in dentifrices containing cetylpyridinium chloride, which do not attach to the low surface area silica product in a meaningful level and thus remain available for antimicrobial action. Processes for making the low surface area silica product are also provided.
