The present invention relates to core shell silica particles, wherein each core shell silica particle comprises a silica core, and a surface of the silica core is etched with metal silicate, the core shell silica particles prepared by: i) admixing an amount of silica particles in water with an amount of a base, wherein the base comprises a monovalent metal ion, to produce core shell silica particles, each core shell silica particle comprising a silica core, and a surface of the silica core etched with a silicate of the monovalent metal ion; and ii) reacting the core shell silica particles formed in step i) with a metal salt comprising a second metal ion, to form core shell silica particles comprising silicate of the second metal ion on the surface of the silica core.

Core shell silica particles and use for malodor reduction

This invention provides core shell silica particles, wherein each core shell silica particle comprises a silica core, and a surface of the silica core etched with group I metal silicate. These core shell silica particles have high surface charge density and anti-bacterial activity. Also provided are compositions comprising core shell silica particles, process of making the core shell silica particles and methods of reducing or inhibiting bacterial activity by administering the core shell silica particles or compositions thereof.

Core shell silica particles and uses thereof as an anti-bacterial agent

Oral care compositions and methods for the same are provided herein. The oral care composition may include an orally acceptable vehicle, a peroxide whitening agent, and one or more gelling agents. The gelling agents may include a fatty acid. The gelling agents may be free or substantially free of fatty alcohols. The gelling agents may include at least one of palmitic acid, stearic acid, or mixtures thereof.

Oral care compositions

Oral care compositions comprising: In one embodiment, the carrier comprises a film forming material. Methods are also provided for making an oral care composition comprising:

Oral care composition with cross-linked polymer peroxide

The present invention provides a tooth whitening oral care composition comprising: (i) a dye having a blue to blue-violet color with a hue angle in the CIELAB system ranging from 200 to 320 degrees; (ii) core shell silica particles, wherein each core shell silica particle comprises a silica core, and a surface of the silica core is etched with metal silicate; (iii) an orally acceptable carrier vehicle comprising a non-aqueous solvent; and wherein the composition comprises water in an amount of from 3 weight % to 30 weight %.

Tooth whitening oral care product with core shell silica particles

Compounds and methods for preparing and using the compounds are disclosed herein. The method for preparing the compounds may include contacting a metal ion or salt thereof with an alkali metal polyphosphate salt in an aqueous medium. The method may also include adding a base to increase a pH of the aqueous medium.

Anhydrous oral care compositions and methods for making and using the same are described herein. The anhydrous oral care compositions may include an orally acceptable vehicle, a peroxide whitening agent, and an abrasive system. The abrasive system may include at least one abrasive having a pellicle cleaning ratio (PCR) greater than or equal to 100.
