Description

FIELD OF THE INVENTION The present invention relates to concentrated, finely dispersed, liquid formulations which are stable to the methods of use, containing the active ingredient in liquid form, free from interfering inorganic salts, and diluted with water to form the invention or mixed with other finely dispersed liquid formulations.

It is known that pesticidal (pesticidal) agents can be formulated in so-called "emulsifiable concentrates" by emulsifiers in organic, mainly aromatic, solvents. It is further known that water-soluble pesticidal agents can be formulated in an aqueous medium with emulsifiers and optionally further formulating agents.

It is known, as disclosed in German Patent Publication No. 2,805,251, that pesticidal, in particular herbicidal, active compounds, which belong to the class of compounds of 2,6-dinitroanilane derivatives, are in the form of aqueous emulsions of 10-75%. by weight of herbicide, 0-60% by weight of a substantially water-immiscible solvent, 0.5-10% by weight of emulsifier and 15-70% by weight of a 15% aqueous solution of an inorganic salt.

However, the addition of said amounts of inorganic salts can, in practice, lead to cosine disturbances or to the formation of a fluffy precipitate when combined with other pesticidal formulations in which only a small amount of water is added.

It is also known, although EP-A-47396 discloses, that during storage, stable concentrated emulsions can be prepared from herbicidal phenoxyalkane carboxylic acid esters in aqueous media using ester-soluble emulsifiers and water-soluble dispersants. As an ester-soluble emulsifier, optionally mixed with alkylaryl sulfonates, poly (ethylene glycol) esters of fatty acids, polyethylene glycol ethers of fatty alcohols, and polyethylene glycol ethers of glycerides or alkyl phenols, and polyoxyethylene (oxypropylene) block polymers are used. Dispersing agents include alkylaryl poly (ethylene oxide) containing ammonium, sodium or potassium salts of phosphorylated poly (styrylphenyl) poly (ethylene oxides) or condensation products of long chain aliphatic amines with ethylene amide and phosphate groups.

The amount of oil soluble emulsifier used in the formulation is from 1.01 to 11.1 parts by weight, based on 100 parts by weight of phenoxyalkane carboxylic acid ester. The amount of dispersant is 0.5-5 parts by weight per 100 parts by weight of aqueous solution. Antifoams containing long chain alcohols and silicones are used to prevent foaming.

Experiments in which the above-mentioned phosphorylated alkylaryl poly (ethylene oxide) derivatives have been applied to drugs other than those described in European Patent Application Publication No. 47,396 have shown significant problems in terms of application. up. When stored at 50 ° C for more than three months, disintegration phenomena occurred throughout the formulation, which were only partially reversible.

Similar results were obtained with salts of phosphorylated poly (styrylphenyl) polyethylene oxides ( ^R Soprophor FL), which are used in the preparation of concentrated oil / water emulsions as disclosed in European Patent Application 33,291. The alkyl-aryl-poly (glycol-ether) compounds disclosed in German Patent Publication No. 3 111 934 were also used in combination with alkyl-arylsulfonic acid salts only to produce conditionally stable colloidal emulsions.

German Patent Publication No. 3,009,944 discloses that polyvinyl alcohol and gum arabic used as dispersants in the formation of insecticidal phosphoric acid esters, at low temperature fluctuations, lead to significant disintegration and phase separation. The addition of electrolytes, as is customary in the application of buffer mixtures or to improve stability to low temperatures, has resulted in coagulation and precipitation.

European Patent Publication No. 28 052 discloses a process for the preparation of aqueous, easy-flowing concentrates of the herbicidal napropamide [N, N-diethyl-2-naphthyloxy] propionic acid] in clays, nonionic emulsifiers, lignin sulfonate-based dispersants and antifreeze agents. using agents. However, this process has the disadvantage that its viscosity varies greatly depending on the storage and use temperatures. At higher temperatures, a decrease in viscosity may result in sedimentation phenomena and phase separation.

In addition to the above, other processes are known whereby, as in European Patent Application Nos. 17,001, 29,626 and 52,313, the components used for molding are pre-milled dry in a mill and / or the desired final to a particle size. However, these processes require additional, costly grinding processes and have all the disadvantages associated with dispersions.

The object of the present invention is to eliminate the disadvantages of the known pesticidal formulations containing solvents, inorganic salts or thickeners of mineral origin. In particular, the present invention has been directed to the problem of providing concentrated, finely dispersed, liquid, pesticidal formulations that are stable at -10 ° C, containing the active ingredient in liquid form, containing no organic solvents at all, or containing less than usual amounts of organic solvents. , do not contain disturbing inorganic salts, are stable against hydrolysis and can be diluted with water, either alone or in admixture with other finely dispersed liquid preparations.

Surprisingly, it has been found that certain wetting and dispersing agents which are soluble in water and organic solvents are more effective and substantially more effective than phosphorylated phosphorylated compounds disclosed in European Patent Application Publication No. 47,396.

EN 202052 Water-soluble dispersants of alkylaryl-poly (ethylene oxide) type.

It has been found that the use of propylene oxide and ethylene oxide-based phosphorylated block copolymers or salts thereof, unlike the dispersants described in European Patent Application Publication No. 47,396, results in application-stable formulations with the above-mentioned beneficial properties.

The compositions thus obtained are completely free of inorganic salts and can be used in addition to other pesticides. By varying the polyethylene glycol moiety, the desired viscosity of the formulated composition can be readily controlled, thereby eliminating otherwise conventional mineral dispersants and thickeners.

The process of the invention is applicable to both the 2,6-dinitroaniline derivatives formulated according to German Patent Publication No. 2,805,251 and the herbicidal phenoxyalkane carboxylic acid esters formulated according to European Patent Application Publication No. 47,396. . Likewise, the process of the present invention can be formulated in a stable technical manner for use as fungicides, insecticides, acaricides (acaricides), nematocides (nematodes), pheromones and repellents (insecticides). The process of the invention may also formulate active ingredients, such as disinfectants, for use in the health care sector.

Suitable emulsifiers include nonionic, anionic or cationic surfactants; of these, mixtures containing nonionic and anionic components are used primarily. However, combinations of nonionic and cationic surfactants may also be used. Preferred emulsifiers are, for example, the calcium salt of benzenesulfonic acid, ethoxylated nonylphenols, ethoxylated aliphatic alcohols, ethoxylated castor oil, propylene glycol-ethylene glycol block polymerizates and mixtures thereof.

Water-soluble polymers such as polyvinyl alcohol, polyvinylpyrrolidone and cellulose derivatives can be used as thickeners.

In preparing the compositions of the present invention, the aqueous phase (carrier phase) is first prepared by mixing the dispersant and optionally the di- or polyols with water. The active ingredient to be emulsified is then mixed with the emulsifying agent and finely dispersed in the aqueous phase. For active compounds having a melting point of about 0 ° C or higher, it may be necessary to first form a concentrated solution of the active ingredient in one or more of the organic solvents mentioned above and to disperse these solutions, after the addition of emulsifiers and optionally stabilizers. in the aqueous phase.

However, it is also possible to first mix the dispersant with the active ingredient and then disperse it in the aqueous phase.

The dispersion can be carried out by stirring or optionally shaking and is conveniently continued until the organic phase has reached the desired droplet size. It is recommended that the droplet diameter be set to 1-15 pm. The dispersion is conveniently carried out at room temperature, but may be carried out at lower or higher temperatures.

The compositions of the present invention are particularly useful for formulating active ingredients which, due to their low melting point, can only be unfavorably or not at all transformed into finely dispersed aqueous phase grinders. The compositions of the present invention may also be used to formulate active ingredients whose grinding process requires special safety measures.
