Claim:
A method of producing an oil-in-water emulsion comprising: dispersing an inorganic pigment in a water immiscible solvent; preparing an aqueous phase including water, the aqueous phase separate from said inorganic pigment and said water immiscible solvent, the aqueous phase including at least one ingredient selected from the group consisting of sodium stearate, potassium stearate, titanium stearate, zinc stearate and magnesium stearate, the ingredient having an HLB of about 14 to about 20; combining said water immiscible solvent including the inorganic pigment with the aqueous phase to form an oil-in-water emulsion; and agitating the oil-in-water emulsion for a time sufficient to partition the inorganic pigment into the aqueous phase but prevent the inorganic pigment from agglomerating.
