An IR spectroscopic technique provides methods for measuring the irritation potential of a formulation and to assess the ability of molecules to enhance the permeability of substances into and through skin using samples comprising stratum corneum. Molecules are screened for their performance as chemical penetration enhancers using a unique in silico procedure that may be applied iteratively in an attempt to generate molecules showing successively higher performance. Both the irritation potential and the ability of the molecule to enhance penetration are considered in the in silico approach. The invention provides specific molecules that may be used in topical or transdermal formulations to improve the delivery of actives. The structures of compounds of the invention include: Formulas (I), (II), (III), (IV), (V), (IV) and analogs thereof.
