Comparison of diffusion by anionic surfactants through cellulose acetate and collagen membranes

From a dermatological point of view, it is important to know what is the irritation potential of surfactants on human skin. Recent research trends have been oriented towards the establishment of new ' in vitro ' techniques that will avoid animal experimentation.
In this paper, some results on the rate of diffusion of different anionic surfactants through both cellulose acetate and collagen membranes are described. A correlation between results of diffusion through the protein membrane and results published on the same surfactants and their irritation potential during ' in vivo ' experiments appears possible.
