  • Publication number: 20220249407
    Abstract: The present invention relates to: an aqueous (a water-soluble) antiseptic composition having improved antibacterial persistence comprising chlorhexidine or a derivative thereof and a silicon-based emulsifier; and a fabric type antiseptic comprising same. As the chlorhexidine or the derivative thereof is highly soluble and stable and well dispersed in an aqueous phase, the composition can exhibit excellent absorption efficiency when applied onto the skin and can ultimately maximize a cumulative emission amount of chlorhexidine or the derivative thereof. In addition, the use of the polyglyceryl fatty acid ester allows sustained release of chlorhexidine or the derivative thereof, thereby sustaining the antibacterial effect for a long time.

  • Patent number: 9622986
    Abstract: Provided is a transdermal delivery system (for example, in the form of a patch) having a double-layer structure including a drug-containing matrix layer and an adhesive layer, wherein the drug-containing matrix layer is obtained by completely dissolving donepezil using a certain polymer and then formulating along with an adhesive; and a process for preparing the same. The transdermal delivery system according to the present invention does not show any crystallization of donepezil in the formulation, can release donepezil at a uniform rate for a long time, and can inhibit the release dumping phenomenon that occurs in a transdermal delivery system having a single-layer structure.
