The present invention relates to combinations of surfactants and solvents (surfactant / solvent mixtures). The surfactant / solvent mixtures can be used for the preparation of formulations of one or more active substances, in particular of agrochemical active substances.

The surfactant / solvent mixtures according to the invention are suitable, for example, for the preparation of active ingredient formulations such as emulsions and suspensions and their concentrates or granules such as water-emulsifiable granules, in particular of liquid active substance formulations such as oil suspensions, Oil suspension concentrates, suspoemulsions, suspoemulsion concentrates, emulsions eg based on W / O or O / W, emulsion concentrates, microemulsions, microemulsion concentrates, and (aqueous) spray mixtures obtainable therefrom.

The invention thus also relates to active ingredient formulations, in particular agrochemical active ingredient formulations, such as liquid agrochemicals, e.g. herbicidal, insecticidal or fungicidal active substance formulations containing,

(1) one or more active substances, in particular agrochemical active substances such as herbicides, insecticides, fungicides or safeners,

(2) the surfactant / solvent mixture according to the invention,

(3) optionally further organic solvents and

(4) optionally conventional auxiliaries and additives such as thickening and thixotropic agents, wetting, anti-drift, adhesion, penetration, preservation and antifreeze agents, antioxidants, fillers, carriers, dyes,

Fragrances, defoamers, fertilizers, evaporation inhibitors, as well as the pH and viscosity affecting agents, and

(5) optionally water.

With the surfactant / solvent mixtures according to the invention can be stable

Make drug formulations, especially of water-sparingly soluble drugs, e.g. those with a solubility less than 5 g / l of water. These agents may e.g. Dyes, agrochemical active ingredients, adhesives, explosives, pharmaceutical or veterinary active ingredients, cleaners, fragrances or proteins, are preferred agrochemical active ingredients.

As agrochemical active ingredients (1) come e.g. Herbicides, insecticides, fungicides (preferably those which are not azole compounds), safeners and growth regulators. Preferred are herbicides, e.g. leaf-active herbicides such as ALS inhibitors (e.g., sulfonamides such as flucarbazone,

Propoxycarbazone or amicarbazone or sulfonylureas such as mesosulfuron, lodosulfuron, amidosulfuron, foramsulfuron), diflufenican, or bromoxynilhaltige Products containing loxynil, herbicides from the class of aryloxyphenoxypropionates such as fenoxaprop-p-ethyl, sugar beet herbicides such as Desmedipham, Phenmedipham, Ethofumesate or Metamitron, or also active substances from the class of HPPD inhibitors (eg isoxaflutole, sulcotrione, mesotrione).

If the active ingredients contain one or more asymmetric C atoms or double bonds which are not stated separately, all isomers are included. The possible defined by their specific spatial form possible stereoisomers, such as enantiomers, diastereoisomers, Z and E isomers are all included and can be obtained by conventional methods from mixtures of stereoisomers or prepared by stereoselective reactions in combination with the use of stereochemically pure starting materials. The stereoisomers mentioned in pure form as well as their mixtures can thus be used according to the invention.

For the purposes of the present invention, the active compounds which are contained as components in the active substance formulations according to the invention are always, in addition to the neutral compounds, their salts with inorganic and / or organic counterions. Thus, for example, sulfonylureas can form, for example, salts in which the hydrogen of the -SO ₂ -NH group is replaced by a cation suitable for agriculture. These salts are, for example, metal salts, in particular alkali metal salts or alkaline earth metal salts, in particular sodium and potassium salts, or else ammonium salts or salts with organic amines. Likewise, salt formation can take place by addition of an acid to basic groups, such as, for example, amino and alkylamino. Suitable acids for this purpose are strong inorganic and organic acids, for example HCl, HBr, H ₂ SO ₄ or HNO ₃ .

Herbicides contained in the agrochemical compositions according to the invention are, for example, ALS-I inhibitors (acetolactate synthetase inhibitors) or herbicides which are different from ALS inhibitors, such as herbicides from the group of the carbamates, thiocarbamates, haloacetanilides, substituted phenoxy, naphthoxy and Phenoxyphenoxycarbonsäure derivatives and Heteroaryloxyphenoxyalkancarbonsäure derivatives, like Chinolyloxy, Chinoxalyl oxy, Pyridyloxy, Benzoxazolyloxy and Benzthiazolyloxyphenoxyalkan-carbonsäureester, Cyclo hexandionabkömmlinge, phosphorus-containing herbicides, eg of the Glufosinate type or of the Glyphosate type, as well as S- (N-aryl-N-alkylcarbamoylmethyl) dithiophosphoric acid ester.

The ALS inhibitors are in particular imidazolinones, pyrimidinyloxypyridinecarboxylic acid derivatives, pyrimidyloxybenzoic acid derivatives, triazolo-pyrimidine-sulfonamide derivatives and sulfonamides, preferably from the group of sulfonylureas.

Preferred ALS inhibitors are derived from the series of sulfonylureas, e.g. Pyrimidine or triazinylaminocarbonyl [benzene, pyridine, pyrazole, thiophene and (alkylsulfonyl) alkylamino] sulfamides. Preferred substituents on the pyrimidine or triazine ring are alkoxy, alkyl, haloalkoxy, haloalkyl, halogen or
