Patent ID: 8734821

Claim:
A composition comprising a blend of a first silicone surfactant of the formula wherein n=2-4, y=3-10, z=0-5, and R=alkyl having 1-4 carbon atoms, and a second silicone surfactant of the formula wherein n=2-4, y=3-10, z=0-5, and R=OH, H, O-alkyl having 1-4 carbon atoms, provided that when z=0, R=H and when z=1-5, R=OH or O-alkyl having 1-4 carbon atoms, wherein the composition is a liquid solution of the first and second silicon surfactants and the total weight percent of the first silicone surfactant and the second silicone surfactant ranges from about 0.1% to about 1.5% by weight; wherein the first surfactant and the second surfactant are present in a concentration such that the composition exhibits synergistic knockdown (KD) level on treated arthropods in a period of less than about 60 seconds after treatment of the arthropods with the composition.
