Coated particles of metal (such as calcium) silicate that exhibit excellent odor neutralization and sebum absorption properties when present within certain cosmetic and/or personal care formulations and suspensions are provided. Uncoated calcium silicate exhibits a high pH level that may have a deleterious effect upon such cosmetic and/or personal care compositions, thereby rendering the overall composition ineffective for its intended purpose, particularly if the calcium silicate is present in its usual state at high loading levels. Alternatively, if certain materials present within personal care compositions exhibit a sufficiently low pH level, the effectiveness of such calcium silicates may be compromised as well. Such novel coated/treated calcium silicates thus permit high loadings of this beneficial odor neutralizing/sebum absorbing additive within cosmetic and/or personal care formulations without causing any appreciable instability issues or viscosity modification concerns or allow for coexistence with such low pH materials without any appreciable reduction in performance capabilities of the calcium silicates themselves. Certain personal care compositions comprising these novel coated calcium silicate particulates are encompassed within this invention as well.

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.
