  • Publication number: 20040241108
    Abstract: An oral composition comprises a particulate amorphous silica and a cationic antibacterial agent characterised in that the particles of said amorphous silica have a polyether glycol deposited thereon. The silica used in the composition of the invention has a good compatibility with the cationic antibacterial agent.

  • Patent number: 6165510
    Abstract: A cosmetic composition includes an inorganic material in granular form which, under condition of use of the cosmetic composition, breaks down to a particle size wherein less than 5% by weight, preferably less than 2% by weight, most preferably less than 1% by weight is above 45 microns, as measured by wet sieve analysis.
