Description

ADJUVANT FOR AGRICULTURAL SPRAYING FROM ORANGE PEEL OIL INTRODUCTION

[001] The invention relates to the stable microemulsion adjuvant composition for agricultural spraying.

[002] The use of adjuvants in agricultural practice, which can be added to the spray tank to improve application, is increasingly common.

[003] The pH of the tank mixture affects the solubility and effectiveness of many plant protection products, which can result in solid precipitation or degradation of active ingredients. In some cases, water conditioning and adjuvants are used to adjust or buffer the pH and improve the product or solubilization in the mixture, control its ionic state and increase the compatibility of the tank mixture. Some manufacturers have added acidifiers, such as phosphoric acid, citric acid and propionic acid (methylacetic acid) for ethoxylated acid and propoxylated nonionic surfactant and oil mixtures to reduce precipitation, which, however, can reduce the efficiency of penetration of the adjuvant in the plant, especially with the increase in the level of oils.

[004] There is, therefore, a very high demand for stable multipurpose adjuvant emulsion, which acts as an adhesive spreader for the drop on the plant leaf and which increases the penetration of assets and nutrients.

[005] Spray adjuvants are generally grouped into two broad categories: activator adjuvants, used to improve absorption in plant tissue, and may include surfactants, vegetable oil concentrates, nitrogen, fertilizers, humectants and penetrants; and water conditioning adjuvants, which actually broaden the range of conditions under which a specific formulation is used, which can alter the physical characteristics of the spray solution, and include buffering, compatibility, defoaming and drift control agents.

[006] In the case of the present report, the product is a yellowish liquid formulation with density between 0.8 and 1.0, prepared from emulsifiers, such as ethoxylated fatty alcohols, ethoxylated fatty acids, ethoxylated alkylphenol, alkyl benzene sulfonated, phosphate alkyl ester and neutralized alkylsulfosuccinate; orange peel oil or substitutes; terpenes obtained from orange oil or substitute; glycols, such as propylene glycol, monoethylene glycol; butylglycol; dicutiglycol; and demineralized water and biocidal preservative.

[007] The mass composition (% w / w) is given by:
orange peel oil or substitute: 4 to 6%;
water: 50 to 90%;
glycol: 1 to 20%;
ethoxylated alkylphenol: 1 to 5%;
neutralized alkylsulfosuccinate: 1 to 5%;
neutralized sulfated alkylbenzene: 1 to 5%;
biocidal preservative: 0.1 to 0.5%.

[008] The formulation process is done in an industrial mixer, adding the raw materials in the following order:
orange peel or substitute oil,
glycols,
emulsifier,
water and
biocide.

[009] The agitation is kept in high rotation for 2 to 4 hours.

[010] The entire process is carried out in a single mixing tank.

[011] The basic chemical composition is dated by the following formulation:
at least 4% and up to 6% methylated vegetable oil,
at least 50% and up to 90% water,
at least 1% and up to 20% glycol,
at least 1% and up to 5% ethoxylated alkylphenol,
at least 1% and up to 5% of neutralized alkylsulfosuccinate,
at least 1% and up to 5% neutralized sulphated alkylbenzene, and
at least 0.1% and up to 0.5% biocide.

[012] Regarding the physicochemical results:
pH (1%) = 2.00 to 3.00,
aspect (density) = 0.8 to 1.0 containing emulsifiers: ethoxylated fatty alcohols, ethoxylated fatty acids, ethoxylated alkylphenol, sulfonated alkyl benzene, phosphate alkyl ester and neutralized alkyl sulfosuccinate; orange peel oil or substitutes; terpenes obtained from orange oil or substitute; glycols, such as propylene glycol, monoethylene glycol; butylglycol; dicutiglycol; and demineralized water and biocidal preservative, and
aspect (dilution 1: 100) = yellowish liquid.

[013] In other embodiments, one or more oils may be a natural compound, modified by esterification or transesterification, such as an ester, for example, methyl esters, ethyl esters, propyl esters, and is preferably a glycol.

[014] In other embodiments, one or more oils may be a natural compound, modified by transesterification, such as alkyl fatty acid ester, methyl esters pure or mixed with an essential oil, terpenic oils mixed together that are combined with one or more compounds ethoxylates.

TECHNICAL STATUS

[015] The state of the art teaches adjuvants based mainly on oils, typically concentrates of vegetable oil with a high concentration of emulsifiable culture oil, especially base oil and non-ionic surfactant.

[016] The most common method is the esterification of common seed oils, such as methyl - sunflower oil, soybeans, cotton and flax seeds.

[017] Thus, many straight or cyclic, mono- or di-peroxycarboxylic organic peroxyacids are known and disseminated, eg in the detergency segment.

[018] In the case of peroxycarboxylic acids, they are known, eg: diperoxydodecanedioic acid, monoperoxyphthalic acid, diperazelaic acid etc., while in the case of monopersulfates, it is no different, given that the state of the art teaches, for example, amino-derived (poly) peroxycarboxylic acid monopersulfates, the subject of a patent as listed below.
