摘要:
A solid polymeric dispersant composition for water-insoluble actives includes a primary anionic polymer dispersing agent and a co-dispersant which is a vinyl lactam, in a defined weight ratio, and wettable powders, water dispersible granules and tablets thereof, for delivery of actives to a desired site.
摘要:
A matrix composition for making a stable microemulsion for an active ingredient includes a C8-C18 N-alkyl pyrrolidone with little or no N-methyl pyrrolidone, and a water-insoluble organic solvent soluble therein, preferably more hydrophilic than said C8-C18 alkyl pyrrolidone and with low water solubility.
摘要:
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 C8-C18 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.
摘要:
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.

摘要:
A delivery system for delivering bioactive materials as an aqueous nanoparticle dispersion of a water soluble matrix of polyvinylpyrrolidone (PVP) polymer and copolymers thereof, and an anionic surfactant.
摘要:
This invention relates to the stabilization of o/w microemulsions containing an active aza biocide by addition of an alkaline, water soluble buffering agent in an amount sufficient to adjust the pH to between 6 and 14 and to the use of said o/w microemulsions to control infestations and/or infections when topically applied to livestock or domestic animals.
摘要:
What is described is an aqueous, flowable suspension concentrate of an agriculturally active chemical having excellent dilution and storage stability, and sprayable aqueous use formulation thereof, containing partially neutralized alkyl vinyl ether-maleic acid half-ester copolymers as dispersing agents therein.
摘要:
This invention relates to a solid delivery system (SDS) for active agricultural chemicals, and, more particularly, to a bioenhanced, stable SDS for sulfonyl and sulfamoylurea agricultural chemicals capable of forming aqueous microdispersions or tank mixes thereof suitable for application to a plant site.
摘要:
A matrix composition capable of forming an emulsion/micro-emulsion comprising an emulsifiable matrix, essentially free of alkyl pyrrolidone and alkoxylated alcohol, comprising: (i) a long chain substituted amide; (ii) a surface active agent; and (iii) optionally, an organic diluent.
