The synthesis and surface behavior of a series of nine new hydrogenated nonionic surfactants and their fluorinated analogs, derived from D-mannitol are described. Adsorption monolayers (Gibbs monolayers) were studied by surface pressure (H) measurements as a function of time. For the spread monolayers (Langmuir monolayers), the measurements of surface pressure versus molecular area (A) were performed
