Transdermal absorption of active substances from cosmetic vehicles

Popis výsledku v původním jazyce

Background:Cosmetic products mean any substance or mixture intended to be placed in contact with the external parts of the human body (eg, epidermis, lips) and should not pass to the lower parts and penetrate to the skin. As a part of evaluation of cosmetic safety, the transdermal absorption of substances should be investigated. Materials and Methods: In vitro absorption was investigated with Franz diffusion cells on untreated porcine skin and specimens of the same treated with 15%wt. SLS. The integrity of the skin was discerned by gauging transdermal electrical conductivity (TEC), the concentration of caffeine absorbed by the samples of skin membrane by liquid chromatography, which took place by applying an emulsion and/or a gel containing active hydration agents (urea, sodium hyaluronate, and sericin). Results: The greatest extent of caffeine penetration was seen for pretreatment with just SLS; similar results were in skin treated with the base gel with 10%wt. urea. In the skin treated with the base emulsion only, the amount of caffeine absorbed was twofold less; this increased after adding the active hydration substances. The values measured for TEC corresponded with the amount of caffeine absorbed. Conclusion: The gel proved to be the more potent vehicle for the active ingredient, as it demonstrated greater transdermal caffeine penetration than the emulsions, correlating with the degree of damage to the skin as detected by TEC.
