Abstract
A microemulsion composition is provided for use as an adjuvant with agrochemicals, comprising an oil phase component, a hydrophilic emulsifier, a lipophilic co-emulsifier and water.
Description
The cross reference of related application
The application requires the rights and interests of the formerly unsettled provisional application series number 60/453,768 of submission on March 11st, 2003, and the document is introduced into as a reference with its full content at this.
Background of invention
The form of the present invention relates to is the liquid adjuvant of microemulsion, and it can combine with agricultural chemicals to improve the effectiveness of agricultural chemicals.
Agricultural chemicals for example biocide, weed killer herbicide, insecticide and even fertilizer comprise and be insoluble to or relatively poor water-soluble organic compound.For these agricultural chemicals being changed into wherein the form that they are handled by the user easily, usually with they as suitable organic solvent for example the concentrated solution in the alkylbenzene sell.Before using, must arrive the concentration that their require by these solution of dilution.Yet the use of these organic solvents is owing to economic cause with especially because ecological consideration is undesirable.Therefore, the concentrate based on water of the agricultural chemicals that need discuss.
Usually, microemulsion is the isotropism that comprises oil, water and emulsifier and nonessential additive, thermodynamically stable mixture, and this additive can comprise pure and mild electrolyte.Emulsifier generally includes oxyalkylated non-ionic surface active agent, and as oxirane, expoxy propane and composition thereof, they prevent that microemulsion is broken to the oil base of separation mutually with mutually water base in relatively limited temperature range.
The microemulsion of this type is murdered many years of thing medicament industry with the existing form service with adjuvant products that is used for agricultural chemicals.The fine droplet size of these emulsions (usually little to about 100nm) causes having the product of the clear of long shelf life.The water component of microemulsion replaces the very most hydrocarbon solvent that usually is used for the hydrophobicity agrochemical concentrate usually, causes eco-friendly preparaton.Yet these microemulsions comprise in a large number the surfactants based on oxirane and expoxy propane inlay and break copolymer, this surfactant biological degradability difference and plant had phytotoxicity.In addition, these block copolymers have cloud point, and this is the known properties of block copolymer and non-ionic surface active agent, and it is the result with the dissolubility variation of the thermometer surface-active agent that increases; (referring to the encyclopedia of chemical technology of Kirk Othmer, the 3rd edition, the 22nd rolls up 360-361 page or leaf (John Wiley﹠amp for " cloud point " to can be observed the temperature that second phase occur; Sons, 1983)).Therefore, if the temperature of microemulsion reaches cloud point, microemulsion will be unsettled.
People's such as Foerster U.S. patent No.6,255,253 disclose the microemulsion formulations that comprises water, emulsifier and oil phase, and this oil phase comprises the water-insoluble agricultural chemicals, and promptly the oil droplet in the microemulsion comprises the agricultural chemicals component.In the mixture of this type, the water-insoluble agricultural chemicals are put into the microemulsion that contains emulsifier and water, make that they are operational at any time basically, although they will dilute before using in afield usually.
Yet, be to preserve agricultural chemicals and adjuvant individually and just before they are applied in the field, they are combined with additional water usually easily.In addition, adjuvant preferably is applicable to the many different agricultural chemicals that can be selected by the user, and is not only the oil base agricultural chemicals.
Therefore, advantageously have microemulsion ecological safety, temperature stabilization, this microemulsion can just mix and increase the effectiveness of agricultural chemicals with water-soluble, water-soluble substantially, water-insoluble or basic water-insoluble agricultural chemicals before they are used.
Summary of the invention
The present invention is the microemulsion as the agricultural chemicals adjuvant, and this microemulsion comprises oil phase component, hydrophilic emulsifier, lipophilic co-emulsifier and water.The microemulsion that obtains is that droplet particle is usually less than the supernatant liquid of 100 nanometers.
According to the preferred embodiments of the invention, oil phase component is an ester, and most preferable ester, hydrophilic emulsifier are alkyl poly glucosides, lipophilic co-emulsifier is glyceride or the sorbitan ester with 6-22 carbon atom, most preferably glyceryl monooleate or mono laurate sorbitan ester.Be suitable for preferably including weed killer herbicide and being used for other material of plant protection, as murder the thing medicament with the agricultural chemicals that microemulsion adjuvant is used; weed killer herbicide; algicide; fungicide; bactericide; virucide; insecticide; aphicide; miticide; nematocide; invertebrate poison etc.; plant biotechnology regulator; fertilizer and nutrient; gametocide; defoliant; desiccant; exterminator; synergist; herbicide-safener (it reduces the phytotoxicity of weed killer herbicide to crops); salt additives (it strengthens the effect of weed killer herbicide); preservative; its mixture etc.
Microemulsion adjuvant of the present invention combines when preferably using in afield with water-soluble or basic water-soluble agrochemicals.Microemulsion adjuvant of the present invention can randomly comprise other typical additives that is used for agrochemical applications.
Find that microemulsion of the present invention increases the effectiveness of agricultural chemicals in the field experiment.In addition, the preparaton of adjuvant can have additional advantage, and this advantage comprises that all components of (1) microemulsion adjuvant can naturally derive, and is biodegradable easily therefore; (2) component of microemulsion can all be " green " chemicals does not promptly need special label; (3) component of microemulsion can reduce the foam formation during agricultural chemicals are used and need not comprise additional froth breaking chemicals in adjuvant.
