Abstract:
The present invention relates to ophthalmic compositions for treatment of conditions in the eye. More specifically, the present invention relates to ophthalmic compositions comprising a polyquaternium compound and an anionic polymer. Methods for reducing and/or preventing the incompatibility of polyquaternium compounds with anionic polymers are also disclosed.

Claim (Index 21):
A method of reducing, inhibiting or preventing the precipitation of a polyquaternium compound and an anionic polymer in a composition comprising such compounds, comprising the steps of:\n i) providing from about 0.001% to about 0.5% of an anionic polymer having a weight average molecular weight of from about 250 to about 4,000,000 Daltons; ii) adding an effective amount of an organic acid, salts thereof or mixtures thereof, such that the organic acid binds with the monomer units of the polyquaternium compound at at least a 1:1 molar ratio; and iii) adding from about 10 ppm to about 1000 ppm of a polyquaternium compound having a weight average molecular weight of from about 150 to about 15,000 Daltons; wherein the composition is substantially free of cationic oligomer compounds and precipitation inhibiting compounds.
