[Dermo-pharmaceutical efficacy of emulsions with NEO-PCL: galenic and rheological studies]

The future EU prohibition (Directive 86/609/CEE) of using experimentation animals has induced the implementation of non-invasive techniques which are to substitute the present methods. Two non-invasive techniques are used to determine the cosmetological effectiveness of two emulsions formulated on a modern excipient NEO-PCL Base. Furthermore, the incorporation of multiflower honey is analyzed, being carried out the appropriate essays in order to obtain its tipification from a galenic and rheological point of view. After the formulation adjustment, O/W emulsioned systems, eudermic pH, and the rheological parameters to its application on the skin are obtained. Out of the effectiveness study, a high moisturization/emolliency degree is deduced. On the other hand, we conclude that multiflower honey rises the moisturizing power on this kind of products.
