  • Publication number: 20180193231
    Abstract: The present invention relates to a fast disintegrating granular hair cleansing composition in which a wet granulation process, which is a pharmaceutical preparation method, is introduced into a method for preparing a cleanser. The fast disintegrating granular hair cleansing composition is prepared by a wet granulation process so as to be readily disintegrated into granules by using small force, because of a low hardness thereof, and can easily form creamy foam since a large surface area comes into contact with water. In addition, portability, convenience of use and sanitation can be improved when molding is carried out in a single-dose in which the entire amount is used at one time.

  • Patent number: 8728514
    Abstract: Disclosed is a transdermal preparation containing a hydrophobic drug. As a method of continuing the high drug permeation, it is used an unique hydrophilic polymer system in which the drug can be contained in a high concentration under no water environment, a solubility of the hydrophobic drug is decreased as the water is introduced to the patch from the skin, so that the drug is maintained at the saturation concentration even though the drug content is decreased as the drug is permeated to the skin. During the application of the transdermal preparation to the skin, it is possible to continuously permeate the high amount of drug, to maintain the sufficient adhesion during the use and to minimize the skin side effect, because the hydrophilic polymer absorbs the water from the skin. The hydrophilic polymer system can serve the function thereof through the hydrophobic adhesive layer capable of preventing the water quickly absorbed from the skin from being evaporated to the outside of the patch.
