  • HYDROPHILIC/HYDROPHOBIC PHARMACEUTICAL COMPOSITION AND METHOD OF ITS PRODUCTION AND USE
    Publication number: 20210106531
    Abstract: A method of producing a composition in powder form involves the following steps (a) to (c): (a) providing highly dispersed silica particles, hydrophobic silica particles, and a cationic surfactant; (b) forming primary hydrophobic silica particles carrying the cationic surfactant on their surface and/or agglomerates of these primary particles; and (c) mixing the highly dispersed silica particles with the product obtained in step (b), thereby obtaining the composition in powder form; and a composition in powder form obtainable by the method.

  • Pharmaceutical preparation and method of its production and use
    Patent number: 10226425
    Abstract: Thus, the present invention provides a composition in powder form comprising highly dispersed silica particles, polymethylsiloxane particles, and at one or both of a cationic surfactant and an antimicrobial substance, wherein at least 25% by weight of the cationic surfactant is present in primary polymethylsiloxane particles carrying the cationic surfactant on their surface and/or in agglomerates of these primary particles, and/or at least 25% by weight, of the antimicrobial substance is present in primary highly dispersed silica particles carrying the antimicrobial substance on their surface and/or in agglomerates of these primary particles.
