In Vitro Test of Nicotine's Permeability through Human Skin. Risk Evaluation and Safety Aspects

摘要

Permeability tests with Franz' diffusion cells and an in vitro test model were made to evaluate the importance of dermal absorption of nicotine as a pathway for intoxication. Studies were carried out to ensure that safety procedures, when spilling nicotine on skin, are sufficient prevent poisoning. Pure nicotine and nicotine in various concentrations in water or ethanol were applied on human skin or gloves in Franz' cells. Washing was simulated by removing nicotine from skin after 3 or 5 min.
