摘要: 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.

摘要: A bleach composition comprises a peroxygen bleach source (for instance hydrogen peroxide, a perborate or a percarbonate salt) and an activator of the formula I: ##STR1## in which X is O or S; one of E and G is --A-- and the other is --N(R.sup.2)--; A is --O-- or --S--; R.sup.1 is a C.sub.1-50 alkylene group (including cyclo alkylene), optionally interrupted by an arylene group and/or by one or more ether, ester, anhydride, thioether, secondary or tertiary amine, amide or imide linkage, an arylene group or an alkarylene group; R.sup.2, is selected from H, alkyl, aralkyl, alkaryl and aryl; R.sup.3 is alkyl, aralkyl, alkaryl or aryl, or, when E is --N(R.sup.2)--, H; in which R.sup.2 and R.sup.3 can be joined so as to form a heterocyclic ring with the atoms to which they are attached, and/or in which R.sup.1 can be joined with R.sup.2 or R.sup.3 ; and L is a leaving group which may optionally be joined to any of R.sup.1, R.sup.2 and R.sup.3. The activator gives the composition good bleaching at low temperatures, minimal dye and fabric damage and which bleach a wide range of oxidisable stains.
