The present invention relates to a stabilized emulsified or dispersed composition comprising a hydrophobic phase and an aqueous phase, the composition being stabilized by a cationic colloidal coacervate stabilizing agent, the coacervate stabilizing agent comprising an anionic component and a cationic component, the anionic and cationic components being present in a proportion such that the composition has a zeta potential of at least about 20 millivolts. The hydrophobic phase is preferably a non-rosin sizing agent, including a reactive or nonreactive sizing agent, although mixtures of rosin and non-rosin sizing agents can form stable emulsions or dispersions using the coacervate of the invention. Methods of making and using the stable emulsions or dispersions are also disclosed, as is sized paper made using an emulsified or dispersed sizing agent stabilized with the coacervate stabilizing agent of the invention.
A stabilized emulsified or dispersed non-rosin sizing composition comprising a non-rosin sizing agent stabilized by a cationic colloidal coacervate stabilizing agent, the coacervate stabilizing agent comprising an anionic component and a cationic component, the anionic and cationic components being present in a proportion such that the sizing composition has a zeta potential of at least about 20 millivolts.
A method of making a stable cationic non-rosin sizing composition comprising a non-rosin sizing agent and a colloidal coacervate stabilizing agent, the method comprising the steps:
A method of producing sized paper comprising employing in the manufacture of the sized paper a sizing composition comprising a non-rosin sizing agent stabilized by a cationic colloidal coacervate stabilizing agent, the coacervate stabilizing agent comprising an anionic component and a cationic component, the anionic and cationic components being present in a proportion such that the sizing composition has a zeta potential of at least about 20 millivolts.
Sized paper sized with a non-rosin sizing composition comprising a non-rosin sizing agent stabilized by a cationic colloidal coacervate stabilizing agent, the coacervate stabilizing agent comprising an anionic component and a cationic component, the anionic and cationic components being present in a proportion such that the sizing composition has a zeta potential of at least about 20 millivolts.
A stabilized emulsified or dispersed non-rosin composition comprising a hydrophobic phase and an aqueous phase, the composition being stabilized by a cationic colloidal coacervate stabilizing agent, the coacervate stabilizing agent comprising an anionic component and a cationic component, the anionic and cationic components being present in a proportion such that the composition has a zeta potential of at least about 20 millivolts.
