mixtures thereof, and particulates pre-treated with a binder composition comprising at least one silicone oil, at least one ester oil and at least one silicone film former prior to incorporation into the slurry mixture, wherein the binder composition additionally comprises methoxycinnamate.

2. The composition of claim 1 wherein the particulates comprise pigments or powders.

3. The composition of claim 2 wherein the pigments or powders have a particle size of from about 0.01 to 100 microns.

4. The composition of claim 1 wherein the binder comprises ethylhexylmethoxycinnamate.

5. The composition of claim 1 wherein the evaporation residue of the slurry mixture is hydratable with water.

6. The composition of claim 1 wherein the evaporation residue of the aqueous based composition is solvatable with non-polar solvents.

7. The composition of claim 1 further comprising pigments and/or powders having a particle size ranging from about 0.01 to 100 microns;

and wherein the evaporation residue of the aqueous based composition comprises one or more water soluble ingredients in addition to the water soluble or water dispersible polymer.

8. The composition of claim 1 comprising from about 0.1 to 20% water in addition to the evaporation residue.

9. A method for making a slurry powder composition of claim 1 comprising:

(a) combining particulates, a binder composition, and an aqueous based composition comprising at least one water soluble or water dispersible polymer;

(b) subjecting the composition of (a) to slurrying; and

(c) evaporating the aqueous based composition;
