  • Patent number: 9872490
    Abstract: Homogeneous stable liquid agrochemical concentrate formulations which form stable dilutions with water comprises biologically efficacious oil, water, agrochemical dissolved in the water to form concentrated aqueous electrolyte, a stabilizing surfactant, based on non-ionic or non-ionic and anionic or amphoteric surfactant, comprising oil compatible, electrolyte tolerant surfactant and water soluble, electrolyte tolerant surfactant and optionally a polyol component, are useful as tank mix adjuvants. The formulations combine biologically efficacious oil, e.g. crop oil, with an electrolyte agrochemical, particularly water soluble non-selective herbicide such as glyphosate, or electrolyte nutrients particularly water soluble inorganic fertilizers providing nutrients such as nitrogen, phosphorus, potassium or sulphur.

  • Patent number: 8883945
    Abstract: A compound of the formula R1.[(AO)n.—R2]m (I) where: R1 is the residue of a group having at least m active hydrogen atoms; AO is an alkylene oxide residue; each n is independently from 1 to 100; m is at least 2; and each R2 is independently H, a C1 to C21 hydrocarbyl, or an acyl group —OC.R3, where R3 is a C1 to C21 hydrocarbyl group, wherein on average greater than one of the R2 groups is or comprises a C4 to C21 hydrocarbyl group comprising at least two ethylenic double bonds. The compounds are particularly suitable for use in preparing aqueous emulsions or dispersions of resins and polymers, especially alkyd resins.

  • Patent number: 8470742
    Abstract: Oil based emulsifiable concentrates containing a liquid saccharide including a) at least one oil component; b) at least one saccharide, particularly a liquid saccharide solution (LS); c) and at least one non-ionic surfactant. The concentrate may also contain at least one of d) at least one surfactant hydrocarbyl saccharide; or e) at least one anionic surfactant; or f) at least one additional oil soluble non-ionic surfactant. The concentrates are typically homogeneous for at least 24 hours and emulsify readily on dilution into water. The concentrates may also contain an antifoaming agent especially a polysiloxane. Upon dilution in water, the emulsions formed from the concentrates are applied to substrates in combination with agrochemically active ingredients, preferably N-phosphonomethylglycine in the form of its soluble salts, to control weeds.

  • Patent number: 7754674
    Abstract: A liquid and readily flowable composition includes (a) a room-temperature-solid solute, such as a nonionic surfactant, preferably having a hydrophile-lipophile balance from about 11.1 to about 18.4, a (ii) C8-C14 fatty acid, or combinations thereof; (b) an alkoxylated fatty alkanolamide; and (c) water, if needed. The alkoxylated fatty alkanolamide, which is substantially liquid at room temperature, solvates the solid solute to form a homogeneous composition which is liquid and readily flowable at room temperature. The select classes of nonionic surfactants include polyalkylene oxide carboxylic acid esters, ethoxylated fatty alcohols, poloxamers, alkyl polysaccharides, or combinations thereof. Useful alkoxylated fatty alkanolamides include propoxylated fatty ethanolamides.
