A water-dispersible OCN material is described that does not need added hydrophilic polymers to provide dispersibility for at least 7 days at a concentration of about 1-5 mg/mL. These OCN materials also have a UV absorbance maximum in water of about 220 nm and pass through a 0.22 µm pore PES membrane.
