Abstract
There is provided an aqueous composition comprising at least one poorly water soluble compound and at least one pH-sensitive dispersed polymer. Also provided is a method of preparing an aqueous composition, comprising the step of preparing a mixture by mixing such ingredients, where the viscosity of the mixture is less than 1.0 Pa*s.

An aqueous composition comprising
- (a) 2% to 80% at least one poorly water soluble compound, by solids weight, based on the total weight of said aqueous composition,
- (b) 0.1% to 30% at least one pH-sensitive dispersed polymer, by solids weight, based on the total weight of said aqueous composition, and
- (c) 0% to 10% pH-insensitive polymer, by solids weight, based on the total weight of said aqueous composition.
A method of preparing an aqueous composition, comprising the step of preparing a mixture by mixing ingredients comprising
