By forming the salt of zwitterions, dramatic increases in skin and membrane transport may be achieved. The rules for counterion selection followed the covalency of the salt formed and the solubilities of the salt in both the solvent and the membrane.

The permeation of nicotine through human epidermis in vitro, membranes, adhesives, an adhesive-membrane laminate, and the laminate with epidermis was measured. Skin irritation in rabbits was shown to depend on the driving force of nicotine in the don

The use of selected salts of zwitterions of varying polarizability, size, hydrogen-bonding ability and lipophilicity as criteria to improve skin permeation of zwitterionic drugs is described. Prior to this study, it was not appreciated that salts of

For a series of bases, which penetrate through human skin in vitro at similar rates (0.056–0.49 μ m /cm 2 /hr), penetrant p K a is shown to correlate with erythema, edema, and color meter readings. As estimates of irritation, erythema, edema, and

The relationship between pKa and skin irritation in humans was studied for a homologous series of benzoic acid derivatives with predicted permeation through human skin at comparable rates (15-90 μg/cm2/hr). Skin irritation and pKa are strongly corre

The relationship between pKa and skin irritation in man is studied for a homologous series of benzoic acid derivatives, which permeate through human skin at comparable rates (15–88 µg/cm2/hr). Skin irritation and pKa are correlated for pKa ≤ 4.

Sorption of ethanol and water into stratum corneum, delipidized stratum corneum, and triolein as a simple model lipid was investigated. Optima in ethanol sorption and flux are related to dehydration of keratins. There was no optimum for solubility in
