Abstract:
An aqueous composition containing a hydrophobic material, and, more particularly, a water soluble matrix of a water soluble polymer and a water soluble surfactant, in the form of a complex, for stabilizing the hydrophobic material, as a nanoparticulate dispersion or emulsion. A delivery system for delivering bioactive hydrophobic materials as an aqueous nanoparticle dispersion of a water soluble matrix of polymer and a surfactant.
Abstract:
What is described herein is a synergistic matrix composite for making a stable microemulsion in water of an active ingredient comprising a first matrix composition including by wt. (a) 5-30% of a C 8 -C 18 N-alkyl pyrrolidone, (b) optionally, 5-60% of a water insoluble organic solvent soluble therein, (c) 30-70% of a non-ionic emulsifier, and (d) 1-15% of an EO/PO/EO copolymer, and, (e) optionally, 1-5% of a surface active buffering agent, e.g. a branched alkyl ethoxylated phosphate ester, a second matrix composition comprising a polar polymeric material, e.g. polyethylene glycol, and/or a neutralized derivatized vegetable oil, e.g. maleated linseed oil, which composite is capable of loading a higher amount of said active than either composition alone.
Abstract:
A concentrate suitable for forming a stable aqueous composition upon dilution with water includes a water-insoluble active organic compound and a water-insoluble oil-modified alpha-beta unsaturated carboxylic acid.
Abstract:
A wood treatment concentrate includes by weight; (a) 0,1-10% of an active wood treatment chemical, (b) 50-99% of a microemulsion concentrate including: (i) 0.03-80%, preferably 40-70%, of a castor oil ethoxylate or tristyryl phenol ethoxylate, (ii) 0-10%, preferably 0.005-6%, of an ethoxylated phosphoric acid ester as pH buffer, (iii) 0.002-40%, preferably 0.05-29%, of a N-C8-C18 alkyl pyrrolidone and (iv) 0-60%, preferably 0.15-40%, of a N-C1-C4 alkyl pyrrolidone, and (v) 0-30%, preferably 0.5-15%, of an ethylene oxide/propylene oxide block copolymer; and (c) 1-50% of a substituted phenol. The use formulation includes (d) water of dilution.
Abstract:
What is described herein is an aqueous dispersion for coating water-soluble granules of a water soluble active agricultural chemical to substantially increase the rain fastness of the active. The dispersion includes by wt.: (a) at least 0.1 % of a polymeric anionic dispersing agent, (b) 5-30% of a water-insoluble, natural or synthetic inorganic or organic polymer, and (c) to 100% of water.
Abstract:
This invention relates to a single phase emulsifiable concentrate composition comprising (a) between about 0.05 and about 25 wt.% of a biologically, fungicidally and/or herbicidally active aza compound; (b) between about 2 and about 40 wt.% of a lactam selected from the group of N-methyl pyrrolidone, N-methyl caprolactam, a C8 to C18 alkyl pyrrolidone, a C8 to C18 caprolactam and a mixture thereof; (c) between about 2 and about 20 wt.% of a moisture scavenging agent selected from the group consisting of a liquid molecularly hindered carbodiimide, a molecular sieve or a mixture thereof and (d) between about 10 and about 80 wt.% of a mixture of at least two non-ionic surfactants having an overall hydrophilic/lipophilic balance (HLB) above 7. The invention also relates to the stable oil-in-water (o/w) miniemulsions prepared from the above by dilution to between about 40 and about 99.99 wt.% water for a "pour on", dip or spray solution useful in the treatment of animals or plants.
Abstract:
A water miscible emulsion composition which is essentially free of long-chain alkylpyrrolidone and aromatic oil comprising: (i) a long chain substituted amide; (ii) a water insoluble film forming polymer; (iii) a water soluble anionic surfactant; and (iv) optionally, a bioactive, is particularly useful in providing water repellency and delaying the onset of fungi growth on crops and leaves.
Abstract:
A stable, aqueous suspension concentrate which includes a solid polymeric dispersant comprising one or more anionic polymeric dispersing agents, optionally a co-dispersant which preferably is a homopolymer and/or a copolymer of a heterocyclic vinyl lactam, preferably in a wt. ratio of 0.1:1 to 1 :0.1 , a UV-labile, water-insoluble biocide active, and a UV-blocker or UV-absorber to stabilize said active upon storage and/or exposure to sunlight or UV radiation.
Abstract:
What is described herein is a stable microemulsion concentrate and composition for delivery of an active biocide/disinfectant in an aqueous medium providing sustained release of the active. The composition is effective against both bacteria and fungi.
Abstract:
A matrix composition for making a stable microemulsion for an active ingredient includes a C 8 -C 18 N-alkyl pyrrolidone with little or no N-methyl pyrrolidone, and a water-insoluble organic solvent soluble therein, preferably more hydrophilic than said C 8 -C 18 alkyl pyrrolidone and with low water solubility.
