Definitions

  • This Patent of Invention comprises a composition of coadjutant substances added to copper compound suspensions capable to increase the stability of such formulations thereby increasing the service life of the final product and also comprises the method for preparation of such compositions.
  • water insoluble copper compounds concentrated suspensions (copper hydroxide, copper oxychloride, cupric oxide, cuprous oxide, tribasic copper sulfate, etc) are usually used in the agrochemical sector, besides being applied to other sectors, such as: a) Copper oxide: welding paste, catalyst, metallurgical industry; b) Copper hydroxide: ceramics, metallurgical industry; c) Copper oxychloride: fireworks, paints; d) Copper tribasic sulfate: veterinary industry, etc.
  • inert coadjutant substances (solvents, dispersants, moisteners, anti-foamiers, etc.) compatible with the intended suspension compound. That way, the study of the formulation stability in the presence of such substances is essential to determine if the coadjutant is able to arouse alterations in the physical and chemical characteristics of the compounds (or in the mixture of the compounds).
  • Concentrated suspensions of water insoluble copper compounds were prepared in the presence of several inert coadjutant substances (in this case, tense-active substances) typically present in concentrated suspensions of agrotoxic substances, cosmetics and medicine drugs.
  • coadjutant substances typically present in concentrated suspensions of agrotoxic substances, cosmetics and medicine drugs.
  • other coadjutant types were tested, such as: antifreezes, anti-foamiers, adhesive and compatibilizing agents.
  • the evaluated adjutant substances presenting the best compatibility/ stability ratio were chosen for the final formulation of this invention.
  • This invention comprises the formulation of an insoluble copper compound suspension that remains in the stock tube without phase separation for time periods exceeding twenty (20) months and for up three (3) days after dilution in water for using.
  • Such formulation is prepared with the following components: water, dispersing agent (ethylene oxide/ propylene oxide condensate or akyl, aryl, ethoxylate alkylaryl or lignosulphonated or formaldehyde condensate or mixtures thereof), moistening agents (naphthalene formaldehyde condensate or naphthalene- formaldehyde sulphonate or polycarboxylate or mixtures thereof), antifreeze agents (ethylene glycol or propylene glycol or ethylene or mixtures thereof), adhesive (precipitated silica or polyvinyl alcohol or polyvinylpyrrolidine or polyacrylamide or mixtures thereof) and anti-foamier (silicone solutions at 10 to 100%).
  • dispersing agent ethylene oxide/ propylene oxide condensate or
  • the insoluble copper compound is added to that mixture and after the solution is homogenized the stabilizing agent gel is added which had been previously prepared (24 hours in advance), mixing the powdered stabilizing (xanthan gum or gar gum or hydromethylcellulose or mixtures thereof) with the preserving agent (formaldehyde solution 38% or methyl or propyl parahydroxibenzoate or 2-bromo-2-nitro-propane-l,3-diol or sodium benzoate or glutaraldehyde or benzoisotiazolinones) in water.
  • the preserving agent formaldehyde solution 38% or methyl or propyl parahydroxibenzoate or 2-bromo-2-nitro-propane-l,3-diol or sodium benzoate or glutaraldehyde or benzoisotiazolinones
