  • Silica-coated boehmite composites suitable for dentifrices
    Patent number: 7166271
    Abstract: Disclosed is a composite material comprising a boehmite substrate coated with a precipitated silica, the composite having a BET specific surface area of from 1 m2/g to 50 m2/g, such that the composite material has a % silica coating parameter value of about 5% to about 50%. Also disclosed is a dentifrice comprising this composite material. When included in a dentifrice composition, the composite material not only provides excellent abrasive and cleaning performance but also has compatibility with other ingredients used in dentifrice formulations, such as fluoride, flavors and cationic species.

  • Precipitated silica product with low surface area, dentifrices containing same, and processes
    Patent number: 6946119
    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.
