    Abstract: Dispersion containing, in addition to water, 0.5 to 20% by weight of hydrophobic silica, 0.01 to 10% by weight of a gelling additive, or viscosity-increasing additive which, as further components, contains at least one phenol or at least one phenol derivative and/or at least one aldehyde. It is prepared by dispersing the individual components successively or together in water, in which case the individual components are deaerated before and/or during the addition or the dispersion is deaerated during the individual dispersion steps and thereafter the residual air present in the dispersion is removed by application of vacuum. The dispersion can be used as insecticide and for controlling pathogenic agents.

    Abstract: Aqueous dispersion containing pyrogenic titanium, zinc, iron or cerium oxide particles with a median particle size below 250 nm and an asymmetric particle size distribution includes a dispersant selected from phosphate esters and copolymers of maleic compounds and optionally alkoxylated allyl alcohol. Aqueous dispersion containing pyrogenic titanium, zinc, iron or cerium oxide particles with a median particle size below 250 nm and an asymmetric particle size distribution includes a dispersant selected from phosphate esters of formula (I) and copolymers of formula (IIb) and/or (IIb); R = (un)saturated 6-22C alkyl or hydroxyalkyl; A = 2-4C alkylene; M = H, alkali metal or NH4; a = 0-30; b = 0-2; Ma = H, a mono or divalent metal cation, NH4 or organic ammonium; X = OMa, O(CpH2pO)qR1, NHR2 or NR22; R1 = H, 1-20C aliphatic hydrocarbyl, 5-8C cycloaliphatic hydrocarbyl or optionally substituted 6-14C aryl; p = 2-4; q = 0-100; R2 = R1 or CONH2; Y = O or NR2; A1 = 2-4C alkylene; m = 10-30; n = 0-50; k = 10-30; m+k = 20-60. An Independent claim is also included for production of the dispersion by dividing a stream of a predispersion comprising the oxide particles and dispersant and optionally additives into at least two substreams, passing the substreams through a high-energy mill under a pressure of at least 500 bar, expanding the substreams through a nozzle, contacting the substreams with one another in a gas- or liquid-filled reaction chamber, and grinding the product.
