The rheological behaviour of Carbopol Ultrez 10 ethanolic (15%) gels was studied as a function of two main variables: pH (4.0-7.0) and the polymer concentration (0.1-0.5%). Flow curves of all hydroalcoholic gels were adjusted to the Ostwald model. Sigmoidal dose response functions were obtained to describe the pH dependence of consistency index of the(More)
The rheological characterization of Carbopol Ultrez 10 ethanolic (15%) gels is complemented by studying flow behavior as a function of temperature (20-50 degrees C) at different pH (4.0-7.0) and polymer concentrations (0.1-0.5%). Flow curves were adjusted to the Ostwald model, showing a fall in viscosity, together with an enhancement in flow index with(More)
The objective of this study was to design an all-trans retinoic acid (RA) topical release system that modifies drug diffusion parameters in the vehicle and the skin in order to reduce systemic absorption and the side-effects associated with topical application of the drug to skin. Three cases of application of hydrogels containing RA either in free form or(More)
This research study is based on the design and development of a semisolid emulsion system whose novel self-emulsifying base and preferentially moisturizing actives were investigated to find out whether the system mentioned could be used as a dermatological treatment for highly sensitive skins, including atopic ones. Thus, one of the main objectives of the(More)
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(More)
We have designed, elaborated and studied a dermopharmaceutical form formulated on the basis of a modern self-emulsifying excipient and rosemary honey (known as Miel de La Alcarria--Spain--according to the Governing Council), in order to obtain a hight degree of cutaneous hydratation. The formulation is typified and characterized from a pharmacotechnical and(More)
Cold-Creams have been used since the times of Galen (II cA.D.) as dermo-pharmaceutical and cosmetic emulsions. This paper proposes a modern Cold-Creams formulation with variations to improve both the formula as well as the properties and applications of the traditional cerates. Basically, a modern self-emulsionable excipient with isopropyl myristate is(More)
