- a) an aprotic organic solvent comprising, with respect to the total composition, from about 200 g/L to about 999 g/L;
- b) a polymer or oligomer capable of hydrogen bonding comprising, with respect to the total composition, from about 1 g/L to about 200 g/L;
- c) a dispersed active ingredient comprising, with respect to the total composition, from about 1 g/L to about 700 g/L;
- d) a clay or silica rheology modifier comprising, with respect to the total composition, from about 1 g/L to about 200 g/L;
- and
- e) at least one surfactant comprising, with respect to the total composition, from about 1 g/L to about 600 g/L.
