Provided is a stable aqueous dispersion suitable for application to different substrates and especially to paper substrates for producing a barrier layer against compounds of the saturated and aromatic hydrocarbon type. The aqueous dispersion comprises destructurized starch in a complexed form. Also provided is the use of aqueous dispersion as a coating composition for paper based substrates, as a microencapsulant of fragrances and as a film-forming component for paints.

Oil and grease resistant paper products are disclosed that include a substrate and, on at least one side of the substrate, a continuous layer of a barrier coating, the barrier coating comprising a binder system and a pigment. The barrier coating, when applied to the substrate and dried to form a barrier layer, has a Pigment Volume Concentration (PVC) that is below a Critical Pigment Volume Concentration (CPVC) of the barrier coating, providing a continuous three-dimensional film of the binder system. In some implementations the binder system comprising a latex and a natural binder and/or the paper product further includes a topcoat disposed on a side of the barrier coating opposite the substrate.
