In this critical article, the authors have reviewed numerous studies in order to elucidate the mechanism of action of the highly purified diethylene glycol monoethyl ether TRANSCUTOL® on skin penetration and permeation.

Development of a daphnetin transdermal patch using chemical enhancer strategy: insights of the enhancement effect of Transcutol P and the assessment of pharmacodynamics.

  • Scientific publication

Drug Dev Ind Pharm. 2018 Oct;44(10):1642-1649. doi: 10.1080/03639045.2018.1483391. Epub 2018 Jul 2. - Jul 2018

A patch for transdermal delivery of daphnetin was developed using Transcutol® P as permeation enhancer.

The study showed:


10% Transcutol® P led to a significant increase in drug release from the patch.
Patch exhibited analgesic and anti-inflammatory activity
