  • Publication number: 20090004256
    Abstract: An adhesive patch for external use which is significantly inhibited from causing a rash, is less irritative to the skin, and sufficiently retains adhesion to the skin. The adhesive patch is characterized by employing a pressure-sensitive adhesive base into which a sucrose fatty acid ester has been incorporated. It does not exert physical influences on the skin, such as stresses imposed on the skin during wear and upon peeling, while sufficiently retaining adhesion to the skin. It is significantly inhibited from causing a rash, and the skin irritation thereof has been minimized. This adhesive patch for external use has ideal, lowly irritative properties which have been impossible to any conventional adhesive patch for external use.
