Determination of the hydratation capacity of active ingredient

Low field NMR (20 MHz) applications have been developed to access to the compartmentalization of water in contact with the active ingredient, the skin or the hair (highly bound / bound / free water) and to the binding forces of the different compartments of water. These methods can be used for example to provide scientific and marketing arguments on the hydration capacity of active ingredients, to study the benefic effect of an active ingredient or of a formula on the skin or the hair, to compare the effectiveness of active ingredients in terms of hydration, to work on a simple model in vitro...
