    Abstract: The present invention relates to an organopolysiloxane compound having at least one group having the formula ##STR1## and at least one group having its formula selected from --R.sup.3 --C.sub.6 H.sub.5 or --R.sub.3 --O--C.sub.6 H.sub.5 per molecule wherein R.sup.3 is a divalent hydrocarbon group having from 1 to 20 carbon atoms, R.sup.4 is hydrogen, an alkyl group, an aryl group, or an acyl group, d has a value of 0 to 150, e has a value of 0 to 150, with the proviso that the value of d+e is at least one. The organopolysiloxane compounds of this invention reduce the amount of foam in the hydrocarbon fuel, especially in diesel fuels and jet fuels. The organopolysiloxane compound acts as a foam control agent which displays consistent compatibility and miscibility with additives which are frequently present in hydrocarbon fuels.

    Abstract: The specification discloses a method of controlling foaming of liquid hydrocarbon fuels (e.g. diesel fuel and jet fuel) by inclusion therein of certain siloxane polyoxyalkylene copolymer as antifoam agents. The copolymers have an average molecular formula such that oxyalkylene groups of the copolymer provide from about 25% to about 65% by weight of the copolymer. Preferred copolymers are according to the general formulaMe.sub.3 SiO(Me.sub.2 SiO).sub.x (MeR'SiO).sub.y SiMe.sub.3in which each Me represents a methyl group, each R' represents a group according to the general formulaQ(OA).sub.n OZin which Q represents a divalent group attached to the silicon atom, each A represents an ethylene group, n has a value from 10 to 15, Z represents a hydrogen atom or a group OCR" in which R" represents a monovalent group and the ratio x:y lies in the range 1:1 to 11:1, more preferably in the range 3:1 to 7:1.
