Abstract: Precipitated silica comprising porous silica particles having a cumulative surface area for all pores having diameters greater than 500 ? of less than 6 m2/g, as measured by mercury intrusion, and a percentage cetylpyridinium chloride (% CPC) Compatibility of greater than about 85%. 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 silica product including the introduction of sodium sulfate powder during different process steps in order to enhance such a compatibility with CPC are provided.

Abstract: Unique pigments that exhibit excellent light diffusion when applied to a person's skin within an appropriate medium as well as acceptable feel during such application are provided. To be most efficacious for this application, such pigments should meet specific criteria being a proper particle size, having irregular structure (i.e. not smooth), and a non-spherical shape. In such a manner, the subject pigments effectuate the desired ability to diffuse light when applied to skin (in a film of acceptable cosmetic composition) such that optical blurring takes place thereby preventing the appearance of wrinkles. The shape, particle size and irregularity of the pigments are necessary to permit maximum light diffusion effects. The particle size and particle size range also necessarily provides a feel that is sufficiently soft for skin applications. Specific types of pigments, as well as cosmetic formulations including such novel materials are also encompassed within this invention.
