However, in order to respond to the recent demand for safer cosmetics and pharmaceuticals, it is necessary to select a suitable one from the high-boiling esters known to date and listed in the pharmaceutical additive or cosmetic raw material standards. . For example, isopropyl myristate (IPM), which is widely used in pharmaceutical patches, has been pointed out for its skin irritation for some time (Toxicol. Appl. P
Pharmacol. , 59, 555, 1981), although it is approved as a cosmetic raw material, it is obligatory to display the use of IPM on products when selling cosmetics using IPM.

In the present invention, the acrylic pressure-sensitive adhesive 1

It contains 20 to 300 parts by weight of one or more selected from neopentyl glycol dioctanoate, diisostearyl malate, and octyl dodecyl lactate.
These fatty acid esters are characterized in that they increase the solubility of the physiologically active substance in the acrylic pressure-sensitive adhesive, promote the distribution to the skin, enhance the transdermal absorption of the physiologically active substance, and have little skin irritation. Considering the mechanism of action of these fatty acid esters, the fatty acid ester is uniformly dissolved in the pressure-sensitive adhesive, thereby changing the polarity of the pressure-sensitive adhesive and increasing the solubility of the physiologically active substance. A highly polar ester, for example, octyldodecyl lactate, enhances the polarity of the adhesive substrate, thereby increasing the solubility of the highly polar bioactive substance. In addition, these fatty acid esters are low-molecular and promote percutaneous absorption by improving the solubility of physiologically active substances in the skin by penetrating into the skin. In addition, cross-linking imparts an appropriate cohesive force to the pressure-sensitive adhesive and eliminates excessive adhesiveness to the skin, so that skin irritation is small. .

In the present invention, the pressure-sensitive adhesive is crosslinked to improve cohesion. As a crosslinking method, a conventionally used method can be appropriately used. For example, radiation crosslinking, chemical crosslinking, ionic crosslinking, and the like.
