Abstract: Linear alkylsilicone compounds of the formula ##STR1## wherein x=0 to 20, preferably 0 to 10, most preferably 0 to 1; y=1 to 10, preferably 1 to 5, most preferably 1; and R is an alkyl or alkyl ester group containing 6 to 16 carbons, or cyclic alkylsilicone compounds of the formula ##STR2## where m is 0 to 4, preferably 0 to 2, most preferably 0, and n is 1 to 5, preferably 3 to 5, most preferably 4, provided that m+n=3 to 5, are adjuvants for agricultural applications of oil-containing compositions. Especially preferred alkylsilicone compounds have a degree of polymerization of .ltoreq.6 and an alkyl content of .ltoreq.50% by weight. The compounds potentiate spreading of mineral or vegetable oils or oil-containing emulsions in dormant spray oils, crop oil concentrates, pesticides, and the like on difficult-to wet surfaces such as waxy leaf cuticles and arthropod exoskeletons.

Abstract: The present invention teaches the use of novel lipophilically modified organosilicone materials and their use as agricultural adjuvants with carrier oils. The lipophilically modified silicones (LMS) of the present invention include linear organosilicone compounds or certain cyclic organosilicone compounds of the formulae: R.sub.a (Me).sub.3-a Si-[OSi(Me).sub.2 ].sub.x -[OSi(Me)R].sub.y -OSi(Me).sub.3-a R.sub.a wherein a=0 or 1; when a=0, x=0 to 4, y=1 to 4, and when a=1, x=0 to 4, and y=0 to 4, provided that the sum of x+y is .ltoreq.6; or (b) ##STR1## where m is 0 to 4, and n is 1 to 5, provided that m+n=3 to 5. R is the lipophilic group and may be an aryl, substituted aryl, aralkyl, alkyl phenyl ether, substituted alkyl phenyl ether or an alkyl alkyleneoxide group. The compounds potentiate spreading of mineral or vegetable oils or oil-containing emulsions in dormant spray oils, crop oil concentrates, pesticides, and the like on difficult-to-wet surfaces such as waxy leaf cuticles and arthropod exoskeletons.

Abstract: A surfactant blend comprising a polyalkyleneoxide polysiloxane and an organic compound having a hydrophobic moiety containing less than 11 carbon atoms in the main chain or backbone and a method of using the surfactant blend as an adjuvant in pesticide sprays or crop oil concentrates.

Abstract: Synergistic surfactant compositions. Polysiloxane-polyoxyalkylene copolymers in which the polyether pendants bear carboxylic acid groups or salts of carboxylic acid groups are demonstrated to have synergystic interactions with anionic and cationic organic surfactants to improve the surface characteristics of a solution, requiring unexpectedly low concentrations to obtain specific surface tension values or to attain critical micelle concentrations in aqueous solutions. Compositions containing an organic surfactant and a polysiloxane-polyoxyalkylene copolymer bearing carboxyl groups are claimed. A method for modifying the surface properties of an aqueous system by employing such compositions as components of the system is also claimed.

Abstract: A surfactant mixture for use as a pesticide adjuvant comprising an organosilicone compound and a polyalkyleneoxide copolymer.

Abstract: Liquid fabric conditioning compositions are disclosed. The compositions incorporate compatible organosilicones which form mutually soluble mixtures with common fabric softening agents.

Abstract: An antifoam composition and laundry detergent formulation including it. The antifoam composition comprises a selected alkylaminosilicone, finely divided filler particles and a hydrocarbon carrier oil. Optional ingredients include oil/water surfactants and silicone oils. The alkylaminosilicone reduces the surface tension of the hydrocarbon oil and renders the formulation self-hydrophobing.
