TECHNOLOGY FOCUS - AGRICULTURE - Preferred Process: The step (a) further involves adding stabilizing agent selected from allyloxypolyalkylene glycol methyl ether, polyoxyalkylene monoallyl ether and polyoxyalkylene monoallyl acetate to water to obtain the mixture. The process (P1) further involves adding naturally occurring active ingredient and synthetic active ingredient to composition.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The stabilizing agent is selected from at least one of allyloxypolyalkylene glycol methyl ether, polyoxyalkylene monoallyl ether and polyoxyalkylene monoallyl acetate, where the alkylene group is selected from the lower alkyl groups. The aqueous based system comprises water, mixture of polar solvents with water and mixture of non-polar solvents with water. The naturally occurring active ingredient is selected from neem oil, catnip oil, lemon grass oil and citronella oil. The synthetic active ingredient is selected from synthetic pyrethroids, N,N-diethyl-3-methylbenzamide (DEET) and para-methane-3,8-diol. The fragrance is selected from natural fragrances and synthetic fragrances.    TECHNOLOGY FOCUS - PHARMACEUTICALS - Preferred Composition: The composition further comprises a stabilizing agent; at least one naturally occurring active ingredient; at least one synthetic active ingredient; and at least one fragrance. The composition comprises (wt./wt.% basis of the total weight of the composition): acyclic organosiloxane compound (0.001-50); the stabilizing agent (2-30); and the aqueous based system (70-99.9).    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The acyclic organosiloxane compound is at least one modified polysiloxane compound selected from hydroxyl alkyl disiloxanes, polyether modified polysiloxane, polyester modified polysiloxane, polydimethyl siloxane-polyethylene oxide copolymer, polyether trisiloxane copolymer, polyalkylene-modified polysiloxane, linear trisiloxanes, polydiorganosiloxane-polyoxyalkylene copolymers, polyether-polysiloxane copolymer, ABA type silicone compounds, branched silicone compounds, Gemini type silicone compounds, amine based silicone compounds, siloxane glycol copolymers and siloxane-alkylene oxide copolymers. The acyclic organosiloxane compound is polyalkylene oxide modified heptamethyl tri-siloxane, where the alkylene group is selected from the lower alkyl groups. The polyalkylene oxide modified heptamethyl tri-siloxane is polyethylene oxide modified heptamethyl tri-siloxane. ACTIVITY - Insecticide; Insect repellent. 50 Culex female mosquitoes were introduced into Peet Grady chamber. A composition comprising polyalkylene oxide-modified heptamethyl trisiloxane (10 g) in water (1 l) was introduced into sprayer. The composition (4 ml) was sprayed in Peet Grady Chamber. It was observed that within 5-6 seconds the composition exhibited 100% mortality.    MECHANISM OF ACTION - None given.    EXAMPLE - 5 Grams of polyalkylene oxide-modified heptamethyl trisiloxane and allyloxypolyethylene glycol methyl ether was added to 1 l of water in a vessel equipped with a stirrer. The solution was rigorously stirred for about 3-5 minutes at ambient conditions to obtain a homogenous composition.
