Abstract

Solid-state and diffusion NMR spectroscopy are versatile tools that allow for studies of both structure and dynamics of complex solid and semisolid materials. We have developed a suit of pulse sequences based on polarization transfer that is readily applied to studies of formulations and their interactions with biological systems. In the present paper, we illustrate its applicability by using an incompletely hydrated surfactant system (tetradecyl-maltoside, C14G2) and skin (stratum corneum, SC) as examples. In the former case, solid-state NMR has allowed us to study the dynamics of the system at the level of individual functional groups, and also to derive the surprisingly complex... (More)

Solid-state and diffusion NMR spectroscopy are versatile tools that allow for studies of both structure and dynamics of complex solid and semisolid materials. We have developed a suit of pulse sequences based on polarization transfer that is readily applied to studies of formulations and their interactions with biological systems. In the present paper, we illustrate its applicability by using an incompletely hydrated surfactant system (tetradecyl-maltoside, C14G2) and skin (stratum corneum, SC) as examples. In the former case, solid-state NMR has allowed us to study the dynamics of the system at the level of individual functional groups, and also to derive the surprisingly complex C14G2-H2O phase diagram at water contents <5%. For SC, NMR data has allowed us to study the effect of natural moisturizing factor (NMF) on the dynamics of its lipid and protein constituents. The results challenge the conventional view that NMF protects the skin from dryness by increasing its water content.
