Abstract: Polyacrylamide is made by inverse emulsion polymerisation using an oil phase including at least one ester based oil, particularly a vegetable oil, using a primary emulsification system including a polymeric carboxylic surfactant; a low HLB emulsifier; and an oil phase structurant, particularly an ester wax such as beeswax. The use of the combination emulsifier enables the use of vegetable oils especially rape seed (including canola) oil as the continuous in the polymerisation step.

Abstract: Water dispersible solid granular agrochemical formulations, typically in the form of wettable powders, particularly having an average particle size from 5 to 50 &mgr;m, or water dispersible granules, particularly having an average particle size of from 200 &mgr;m to 5 mm, include one or more water dispersible agrochemical active components; and a dispersing agent including a water dispersible styrene (meth) acrylic copolymer. The copolymeric dispersing agent may include monomer residues which include strongly acidic, particularly sulphonic acid groups.

Abstract: Aqueous agrochemical compositions of dispersed phase agrochemicals, particularly phytoactives, such as growth regulators and/or herbicides, or pesticides, such as insecticides, fungicides, or acaricides, include as adjuvant a branched primary alcohol alkoxylate of the formula (I): [CH3.(CH2)n][CH3.(ch2)m].CH.[(CH2)p.O.(AO)q.H] where n, m, p, AO and q have defined meanings are disclosed. In the compositions, the agrochemical can be present as dispersible granules or dissolved or dispersed in an oil. The compositions can be concentrates or diluted sprayable compositions. A particularly convenient form of composition is as dispersible granules.

Abstract: Adjuvants for aqueous agrochemical compositions incorporating hydrocarbyl polysaccharides can be formulated with polyalkylene glycols, particularly polyethylene glycols, without a major loss of effectiveness in the total formulation. The compositions can include other water soluble or dispersible non-ionic surfactants. The agrochemical compositions can be used to kill or inhibit vegetation where the agrochemical includes a growth regulator and/or herbicides, particularly water soluble herbicides, such as a glyphosate type herbicides; or to kill or inhibit plant pests where the agrochemical includes a pesticide, particularly an insecticide, fungicide and/or acaricide.

Abstract: Agrochemical compositions including compounds of the general formula (I), as defined herein, such as, N-(1-deoxy glucityl)N-(2 hydroxy dodecyl)-N-methyl amine, can function as emulsifiers, dispersants or, and particularly, as adjuvants. The agrochemical can be a plant growth regulators, herbicides, and/or pesticides, for example insecticides, fungicides, acaricides, nematocides, miticides, rodenticides, bactericides, molluscicides and/or a bird repellent. Particularly useful formulations include water soluble herbicide(s), particularly such as Glyphosate, Sulfosate, Glufosinate and Paraquat.
