FIELD: stabilized dispersions.
SUBSTANCE: invention relates to emulsification and colloidal stabilization of emulsions and dispersions of hydrophobic phases in aqueous phases using a coacervate. In particular, stable emulsified or dispersed composition of invention, including hydrophobic and aqueous phases, is stabilized by cationic colloidal coacervate stabilizer including anionic and cationic components in a proportion ensuring zeta potential of the composition to be at least 20 mV. Preferred hydrophobic phase is non-colophony reactive or non-reactive sizing substance, although employment of coacervate allows stable emulsions or dispersions of mixtures of colophony and non-colophony sizing substances to be obtained. Furthermore, methods of obtaining and using stable emulsions or dispersions as well as sized paper made using emulsified or dispersed coacervate-stabilized sizing substance are described.
EFFECT: enhanced stabilization of emulsions and dispersions.
