The interactions between small mols. and keratins are poorly understood. In this paper, a NMR method is presented to measure changes in the 1H T1 relaxation times of small mols. in human hair keratin to quantify their interaction with the fiber. Two populations of small-mol. compounds were identified with distinct relaxation times, demonstrating the partitioning of the compounds into different keratin environments. The changes in relaxation time for solvent in hair compared with bulk solvent were shown to be related to the mol. weight (MW) and the partition coefficient, LogP, of the solvent investigated. Compounds with low MWs and high hydrophilicities had greater reductions in their T1 relaxation times and therefore experienced increased interactions with the hair fiber. The relative population sizes were also calculated This is a significant step towards modeling the behavior of small mols. in keratinous materials and other large insoluble fibrous proteins.
