Patent ID: 8623389

Claim:
A physically stable oil dispersion comprising: a) an organoclay stabiliser selected from the group consisting of tetraalkyl ammonium bentonite, tetraalkyl ammonium hectorite and tetra(alkyl/aryl)ammonium bentonite, b) an alkyl ethoxylate emulsifier, c) a low polarity liquid selected from the group consisting of paraffinic oil and mineral oil having a dielectric constant less than 2.5, and d) an oil insoluble pesticide that has a particle size of from about 1 to about 10 μm and is substantially insoluble in the low polarity liquid, wherein the organoclay stabiliser is activated by a method comprising mixing the organoclay stabiliser with the alkyl ethoxylate emulsifier under high shear conditions in the presence of the low polarity liquid at a temperature above 15° C. wherein the ratio range of the organoclay to the emulsifier ranges from about 1:10 to about 1:1.
