  • Patent number: 6518313
    Abstract: Solid sanitizing compositions have advantages over corresponding liquids and powders. A solid sanitizing product can be contained within a plastic bottle with a label indicating that the contents have antimicrobial or deodorizing properties containing a non-flowable solid composition having greater than about 0.02 percent by weight antimicrobial compounds. The preferred solid sanitizing compositions consist essentially of an antimicrobial compound selected from the group consisting of quaternary ammonium salts, fatty amines and diamines, chlorhexidine gluconate, phenol, derivatives of phenol, parachloro metaxylenol and mixtures thereof, and between 0 and 99.98 percent by weight of a cleaning composition. The solid sanitizing compositions can be effectively used with solid dispensers. The solid dispensers have a bowl with a drain at the bottom and an upward pointing spray nozzle.

More specifically the invention is related to the preparation of suspensions of colloidal solid lipid particles (SLPs) of predominantly anisometrical shape with the lipid matrix being in a stable polymorphic modification and of suspensions of micron and submicron particles of bioactive agents (PBAs); as well as to the use of such suspensions or the lyophilizates thereof as delivery systems primarily for the parenteral administration of preferably poorly water-soluble bioactive substances, particularly drugs, and to their use in cosmetic, food and agricultural products. SLPs and PBAs are prepared by the following emulsification process: (1) A solid lipid or bioactive agent or a mixture of solid lipids or bioactive agents is melted.

  • Patent number: 6190700
    Abstract: Disclosed is a method of producing a sustained-release preparation for injection, which comprises adding to microspheres which are obtained from w/o emulsion with a solution containing a physiologically active peptide as an internal aqueous phase and a solution containing a polylactic acid having a weight-average molecular weight of about 5,000 to about 25,000 as an oil phase, a sugar in an amount of about 2 to about 60% (w/w) relative to the microspheres; freeze drying and subsequent heating at the temperature ranging from the glass transition temperature of the microspheres to the temperature which is higher by about 20° C. than the glass transition temperature for about 24 to about 120 hours; and the method of the present invention suppresses microsphere particle aggregation during production process, makes it possible to almost perfectly remove the water and organic solvent in microspheres, and yields microspheres having good dispersibility and storage-stability.
