System of surfactants allow to obtain stable liquid composition of active substances and compositions contain (a) one or more water-soluble active substances (type (a) and (b) optionally one or more water-insoluble active substances (type (b), (C) optionally, organic solvents, (d) the system of surfactants and water. The compositions are either single-phase aqueous or aqueous-organic composition of active substances (a), for example, glufosinate ammonium or glyphosate (salts thereof), or micro-emulsions of the active substances (a) and type (b), for example herbicides based on diphenyl ethers. 3 N. and 10 C.p. f-crystals, 4 PL.

The invention relates to systems of surfactants for liquid is realsie. The invention relates preferably to systems of surfactants for single or multiphase compositions with one or more active substances, with at least one of the active substances soluble in water. Active substances can be, for example, active substances used in areas such as medicine or agriculture, as well as other substances with specific technical functions, such as, for example, dyes. In particular the invention relates to microemulsions of plant protection products with a combination of water-soluble and practically insoluble in water active substances, especially the microemulsions of glufosinate and oxyfluorfen or glifosato and oxyfluorfen.

Often use a combination of active substances with the purpose of sharing the properties of the individual active substances or due to the synergistic effect of the combination of the individual active substances, i.e. sverhsummarny increase activity. In addition, the active substances are usually used in the form of a pure substance, and depending on the application and the required physical properties application, in combination with certain excipients, i.e., and is an expert often faced with the problem of the incompatibility of the individual active substances with each other, and with auxiliary substances in the joint composition. To take full advantage of the combination of active substances of particular interest are the stable cobalt containing composition.

In principle, a combination of different active substances can be prepared in different ways, depending on the biological and/or chemico-physical parameters. In General, as possible compositions take into account, for example, razbryzgivayuschie powder (WP), emulsion oil-in-water or water-in-oil” (W or SW), suspensions (SC), suspension-emulsion (SE) or the granules for soil or for dispersion or water dispersible granules (WG). These types of songs in principle known and described, for example, in: Winnacker-Kuchler. Chemische Technologie, T. 7, publishing house C. Hauser-Verlag, Munich, 4th edition 1986; van Valkenburg. "Pesticides Formulations" Marcel-Dekker, N. Y., , new York, 1973; K. Martens. "Spray Drying Handbook", 3rd edition 1979, G. Goodwin Ltd., , London.

In the case of combined active substances, if we are talking about connections with antagonistic chemical-physical properties, it is of course possible compositions is limited. For example, the broad-spectrum herbicides: glufosinate and glyphosate with festiville highly soluble in water. Herbicides from the group diphenyl ethers, such as oxyfluorfen, on the contrary, practically insoluble in water.

The combined application of herbicides of the type specified above is known. For example, in the application DE-A-19501986 (WO 96/22692, FOR-A-96/0502) described combination glufosinate of ammonia and its salts with oxyfluorfen and are mentioned as possible cobalt containing compositions razbryzgivayuschie powder, water dispersible granules and emulsion oil-in-water”. Other cobalt containing compositions glufosinate ammonium and oxyfluorfen known from application US-A-5324708 and Researche Disclosure 275, (1987), 154. If this describes obtaining granules of such combinations of active substances, see application EP-A-448538 and EP-A-0394211.

Also known, for example, aqueous dispersions of glufosinate or its salts and water-insoluble herbicide J-AND-07089817). Use special popularity aqueous dispersion of glufosinate ammonium and linuron, monolinuron, metolachlor or alachlor (application EP-A-0244754), as well as dispersion of glufosinate ammonium and Diuron or Simazine (application EP-A-0499798).

Combinations of glyphosate (salts) and oxyfluorfen known from the application WO 84/03607 and applications EP-A-0143547.

None of these songs are not one is the second microemulsions or micellar solutions, due to the small particle size (100 nm), optically transparent. A particular advantage of microemulsions is their thermodynamic stability, resulting microemulsions are characterized by a theoretically unlimited storage stability and durability. On the contrary, microemulsion or suspension are, as a rule, only kinetically stable and after different duration of time, it is necessary to take into account the separation of the phases and, consequently, the “decomposition” of the composition.

Compared with the optically transparent emulsion concentrations (EC) microemulsions differ, as a rule, less weight solvent content. Due to a sharp reduction in the voltage at the interface of water and oil phases under the action of appropriate systems emulsifiers it is possible to refuse widespread thickening agent for stabilization of the composition. Since the voltage on the phase boundary and the surface tension is correlated to each other (see equation Jung), then in such micellar solutions often do not require the use of antispyware.

Another advantage of microemulsions is that contained in concentrate very small to the. is therefore under normal dilution with water prior to biological application form finely dispersed solutions for spraying, which prevent clogging of the nozzle of the sprayer. In addition, the microemulsion is prepared mainly with very low energy consumption with the use of technically simple mixers, i.e. already in the process of making obvious advantages compared with the above thermodynamically unstable compositions not only save materials, but also reduce energy costs.

Examples of pesticide preparation of microemulsions is described inter alia in the publications WO-A-9006681, WO-A-9314630, EP-A-160182, EP-A-0533057, EP-A-499587, EP-A-500401, EP-A-432062, DE-A-3624910, DE-A-3235612, EP-A-648414, EP-A-617894.

However, the corresponding microemulsions not contain any of glufosinate ammonium or glyphosate (salts thereof), and described in the above publications, emulsifiers, wetting and dispersing agents in most cases not suitable for the production of microemulsions containing glufosinate and/or glyphosate, their use results in unstable compositions, characterized by a strong turbidity and subsequent separation of the phases.

In addition, it is known that using mixtures of fatty Aminat the ionic surfactants (application US-A-5565409) in the presence of other surface-active components or compatible promoters of the resulting microemulsion of glyphosate (salts) and oxyfluorfen. Given in the publications emulsifiers are purely basic or cationic origin.

In addition to these General advantages of microemulsions also know that microemulsions are so critical systems, as generally sensitive to temperature changes and/or to replace or Supplement the individual components. The modification is the result of adding one or more surfactants in most cases is impossible, and makes it difficult to align the corresponding microemulsions used active substances and combinations or other conditions, such as the proportion of active substances, temperature extremes during storage, climatic zones, etc.

How stable are prepared microemulsions in a separate case, until now it was difficult to predict and required special coordination of all components and the quantitative ratios. Therefore, in principle, there is a need for systems, surface-active substances, which provide stable microemulsions.

It is also known that the activity of pesticides sameboat (salts) have been proposed, for example, alkoxysilane fatty amines (application EP-A-0290416). Along with this, also described isopropylammonium salts of esters of phosphoric acid and three times ethoxylated butanol as a surface-active component to increase the biological activity of glyphosate (salts) (application DE-A-4116516). Similarly occur in the case of glufosinate ammonium strong increase in activity in the presence of sodium sulphate simple digitalimage ether12/S14-fatty alcohol series (application EP-A-0476555, the application EP-A-0048436, the application EP-A-0336151 or application US-A-4400196). It is widely known application of sulphate simple alkylpolyglycoside esters also for a number of other herbicides, including herbicides type diphenyl ether, as an aid penetration and means to improve the effectiveness (application EP-A-0476555). Therefore, there is a particular interest in compositions that are either directly contain such amplifiers activity as excipients, or allow them to integrate into the technically necessary mixture of emulsifiers. In order to achieve the required technical properties of compositions both in relation to their stabily substances. Therefore there is an urgent need for systems of surface-active substances, which provide the implementation of active substances in the composition.

Often also suitable combination of different solvents, additionally containing alcohols, such as methanol, ethanol, n - and isopropanol, n-, ISO-, tert - and 2-butanol.

For single-phase aqueous-organic solutions are applied fully or substantially miscible with water, solvents or solvent mixtures.

To obtain microemulsions used mainly solvents, which are the main constituent of the organic phase, i.e., the solvent or mixture of solvents that are water do not mix or poorly mixed. This can, if necessary, and mixed solvents, partially or infinitely soluble in water.political solvents, such as toluene, o-, m - or p-xylene and mixtures thereof, 1-methylnaphthalene, 2-methylnaphthalene, a mixture of 6-16C-aromaticheskikh hydrocarbons, such as, for example, a series of "Solvesso" (SS), presents the types of "Solvesso" 100 (boiling point: 162-S), "Solvesso" 150 (boiling point: 187-S) and "Solvesso" 200 (boiling point: 219-S)1-C12-alkilany ester of phthalic acid, specially WITH4-C8is an alkyl ester of phthalic acid, is not miscible with water, alcohols, such as, for example, cyclohexanone or isophorone or6-C20-aliphatic hydrocarbons, which may be linear or cyclic, such as series products Shellsol, types T and K or R,R-n paraffins, esters, such as glycerol-triacetate, as well as polar organic solvents, such as N-organic and Dowanol PM (onomatology ether of propylene glycol).

Components that may optionally be included in the compositions as auxiliary substances according to the invention can be, for example, water-insoluble, solid, inert materials, which are often successfully contribute to the stability of the composition. Thus it is possible, for example, to eliminate or slow down the formation of macropus, the precipitation of solid phases and other Suitable inert materials are in the Denia for example, natural resins such as rosin (wood resin, latex rubber) and tannin. Additive resins can be, for example, up to 30 wt.%, preferably up to 20 wt.%, in particular up to 15% by weight of the composition.

Excipients necessary for obtaining the above compositions, in particular, surfactants and surface-active savedata, in principle known and described, for example, in utcheon''s "Detergents and Emulsifiers Annaual", MC Publ. Corp., Ridgewood, N. J; Sisley and Wood, "Encyclopedia of Surface active gents" (encyclopedia of surface-active substances). hem. Publ. With. Inc., N. Y. 1964; Schnfeldt, “Grenzflchenaktive ” (Surfactant adducts of ethylene oxide). Wiss. Verlagsgesellscgaft (Science publishing society), Stuttgart, 1976; "Chemische hnlgi" (Chemical technology), I. 7, ed. C. User-Vrlg, , Munich, 4th edition 1986, respectively cited in the literature.

Although these publications and described in sufficient chemical “structure” of the individual components, but on the basis of these reference materials is not possible to predict the properties of mixtures of such components for the composition of a certain system of active substances. This is true even in the case, to the substances as can be seen from the following table 1. If this case applies, for example, the combination of surface-active substances, which have already been obtained and described microemulsions other active substances (see application DE-A-36234910), for combinations of glufosinate ammonium and oxyfluorfen not described microemulsions, but only unstable multiphase systems (see examples 1 and 4).

A similar situation occurs in the case when instead used in examples 1 and 4 ethoxylated fatty amine as simulator” apply connection, which for different reasons have already been described as a surface-active cowesett, as, for example, n-butanol (example 2). And in this case get a multiphase system instead of the microemulsion. If this is the incorrect assumption that n-butanol is too hydrophobic to in this case be used as surfactants for the formation of microemulsions. As can be seen from example 3 of table 1, with increasing index L the microemulsion is formed. In addition, in the case of glufosinate ammonium and oxyfluorfen when receiving neutralized esters of phosphoric acid in the presence of primary power is required, which do not form stable microemulsions of the combination of active substances (a) and (b), one should not expect that using a system of surface-active substances according to the invention it is possible to obtain microemulsions described in paragraphs (a) and (b) active substances. This applies in particular to mixtures consisting of the main surface-active cowesett (cationogenic components) and complex acidic esters of phosphoric acid (anionic components). For such “katiana-anionic” mixtures of surface-active substances it is expected the formation of water-insoluble, crystalline precipitation. Therefore, a priori, they are totally unsuitable for use as emulsifiers. Unexpectedly it was found that they fit exactly to microemulsion described in paragraphs (a) and (b) active substances. This is shown in table 2 (see below) examples that give an idea about the chemical flexibility of the described component mixtures. Thus it is possible to use complex acidic esters of phosphoric acid of different chemical origin, such as phosphated ethoxylated alcohols of the fatty series on the basis of different fatty alcohols (examples I and III), amoxilin is amoxilonline esters of phosphoric acid plays only a minor role, as is clear from example II. In addition, as the main surfactant cowesett can also be chemically different components, such as alkylamines followed on the basis of various Akilov (examples I and VI) or Minoxidil (example VII). Finally, example VIII clearly shows that may apply even basic amides of carboxylic acids as surface-active savedata or sour the ethoxylated arylphosphate as surface-active substances.

Possible chemical diversity allows you to optimally match the desired system surface-active substances with requirements in the individual case, technical requirements, and it must be borne in mind that the mixture with the component (a) are particularly effective in the case when they contain in excess of basic surface-active movemento (examples 1-VII, IX-XIV) or in excess of a complex acid ester of phosphoric acid (example VIII). The preferred molar ratio (based on equivalents of acid or basic groups) components acidic ester of phosphoric acid: the main surface-active movemento are in particular 1:1,01-1:100 or 1:0.01 or 1:0.01 to 1:0.99, and suppose the about suitable for microemulsion, in particular, mixtures containing both components are surface-active substances (1) and (2) not in equimolar amounts. Preferably, the pH of the composition was therefore to avoid the above-described phase separation in the case of glufosinate ammonium preferred range of pH is about 7. If the pH value is not initially located in the neutral range, as is the case in examples VII and VIII, for his achievements can be used, for example, acetic acid (examples 1-VI, IX, X, XII-XIV).

Using only anionic surfactants such as sulfates or carboxylates esters of alkylpolyglycoside, i.e. without the application of the system of surface-active substances according to the invention, cannot be obtained microemulsion mixtures (a) and (b), because their presence acts “destabilizers”. Use only this kind of anionic surfactants leads, as a rule, for mixtures of (a) and (b) to the formation of thermodynamically unstable systems, such as described in the application DE-A-19501986 microemulsion. However, unexpectedly, were obtained in the case of sulfates and carboxylates esters of alkylpolyglycoside in combination with a sufficiently hydrophobic particlemanager components according to the component of the mixture (d) is thermodynamically stable target composition (example IX or X).

As follows from example XI, described in paragraph(a) of the mixture components can be used to microemulsion water-insoluble active substances, such as oxyfluorfen, in the presence of glyphosate.

In the descriptions of the US-And-5338762, US-A-5326789, US-A-5317042, US-A-5298529, US-A-5300529 and WO-A-9213454 disclosed N-alkyl-pyrrolidone as ingredients pesticide microemulsions. System (d) surface-active substances according to the invention allows to microemulsions combinations of active substances (a) and (b) regardless of the presence of the ingredient N-methylpyrrolidone. Directly explains this example XII.

Microemulsions or micellar solutions obtained according to the present invention contain water. In this part of the water is the water contained in the commercial brands of surfactants or mixtures thereof, the other part is formed with an aqueous solution of herbicides of type (a); to use the mixtures of surfactants really get microemulsions requires, as a rule, the additional amount of water.

System (a) surface-active substances according to the invention forms a stable single-phase aqueous solutions in the absence of organic is pyrrolidon, in combination with the active compounds of type (a). This is illustrated by examples (table 3).

Using mixtures of components (d) can be obtained mainly liquid compositions of glufosinate, or glyphosate, or their salts or other water soluble substances, different content

(a) 1-50 wt.%, preferably 5-20% of the active substance (a),

(b) 0-70 wt.%, preferably 0-10% of the active substance type (b)

(f) 0-20 wt.%, preferably 0-15 wt.% conventional auxiliary substances

(g) 0.1 to 60 wt.%, preferably 10-40% water,

moreover, the weight ratio between the herbicides (a) and listed in paragraph (C) surface-active substances, based on the detergent is preferably from 1:1 to 1:10, especially from 1:1 to 1:5.

Particularly preferred is P CLASS="ptx2">

(b) 1-10 wt.% the active substance is called of type (b)

(C1) 5-30 wt.% organic solvents, forming together with the active substance (b) phase

(C2) 0-30 wt.% water-soluble organic solvents, and the total content of the solvent (C1)+(C2) is mainly from 5 to 30 wt.%,

(a) 10-40 wt.% the mixture of components (d) according to the invention (the system of surface-active substances),

(e) 0-20 wt.%, preferably 0-15% other anionic surfactants, such as alkylphenolethoxylate or alkylphenolethoxylate,

(f) 0-20 wt.%, preferably 0-10 wt.% conventional auxiliary substances

(g) 10-40 wt.% water.

Along with this, the preferred water-phase solutions of the herbicides (a) containing system (d) surface-active substances according to the invention. Such solutions are the optimal form of the herbicides (a). While the preferred herbicide aqueous phase solutions containing

(a) 1-50 wt.%, preferably 5-20 wt.% the active substance is called of type (a)

(d) 3-70 wt.%, preferably 5-50% of a mixture of component (d) according to the invention (with whom the conclusion of phase separation

(f) 0-20 wt.%, preferably 0-15 wt.% conventional auxiliary substances

(g) 10-40% water.

Solvents, primitively to the water phase solution in the process of obtaining, are primarily indefinitely or substantially miscible with water and organic solvents, such as, for example, N-methyl-pyrrolidone, dimethylformamide, dimethylacetamide or simple onomatology ether of propylene glycol.

Traditional excipients (f) of the composition are, for example, called inert materials, antifreeze, evaporation inhibitors, preservatives, dyes, defoamers, etc.; preferred auxiliary substances (f) are

- insoluble in water, inert materials (e.g., oil-soluble resin) up to 30 wt.%,

- antifreeze and evaporation inhibitors, such as glycerol or ethylene glycol, for example, in the amount of 2-10 wt.%,

- preservatives, for example, Mergal K9N (Riedel) or Cobate®,

- defoamers, such as ®Fluowet PL 80 (Clariant), in the amount of osili according to the invention can be obtained in principle by conventional methods, i.e., by mixing under stirring, shaking or using the static methods of mixing. The resulting liquid compositions are stable and stable in storage.

In addition, the liquid compositions are of optimal properties desired for technical applications. As can be seen, for example, in the table 4 measured herbicide activity of active substances glufosinate ammonium and oxyfluorfen prepared in the form of a microemulsion obtained according to the invention for formula 1, undeniably superior to the activity of these active substances in the form of microemulsion. Accordingly, it relates, generally, to other compositions according to the invention. Therefore the composition according to the invention is particularly suitable for suppressing unwanted vegetation.

In the following examples, the quantitative data relate to weight, unless otherwise indicated. The examples of table 1 are comparative examples (examples are not illustrative of the invention) that do not relate to the generation of microemulsions. Table 2 presents examples that illustrate the microemulsion according to the invention. Table 3 shows, in addition, examples, CAS is istia described compositions.
