摘要:
The present invention aims at providing a pressure-sensitive adhesive composition applicable to nail, which shows superior adhesive performance (adhesive force, cohesion etc.), and superior drug releasability and drug stability, and an adhesive agent for nail, which uses this composition. The composition of the present invention contains a condensation polymer of a silicone resin and a silicone rubber. The composition of the present invention preferably contains not less than two kinds of condensation polymers having different resin/rubber ratios. The adhesive agent of the present invention has a support and an adhesive layer formed on one surface of the support, which contains the above-mentioned composition.
摘要:
The present invention provides an adhesive patch including a backing and a pressure-sensitive adhesive layer formed on at least one surface of the backing, in which (a) a surface of the pressure-sensitive adhesive layer has a logarithmic decrement, as determined by the rigid-pendulum free-damped oscillation method, in the range of 0.03 to 0.35, and (b) the pressure-sensitive adhesive layer has a maximum shear displacement in the range of 18 μm to 1,000 μm. The present invention further provides a patch preparation containing a drug. The adhesive patch and the patch preparation according to the present invention are reduced in skin irritation during wear.
摘要:
The problem of the present invention is to provide a composition for enhancing transdermal absorption of a drug, which shows a sufficiently high enhancing effect on transdermal absorption of a drug, particularly, a composition for enhancing transdermal absorption of a drug, which shows a sufficiently high enhancing effect on transdermal absorption of an acidic drug.A composition for enhancing transdermal absorption of a drug, comprising an unsaturated higher alcohol having 12-20 carbon atoms and a polyvalent alcohol having 3-8 carbon atoms. A composition for enhancing transdermal absorption of a drug, comprising an unsaturated higher alcohol having 12-20 carbon atoms, a polyvalent alcohol having 3-8 carbon atoms and an organic amine having 2-9 carbon atoms.
