Download or read book A Novel Rheology Modifier for Agrochemical Formulations written by Juliana Pierobon and published by . This book was released on 2013 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flowable formulations require a rheology modifier to prevent sedimentation phenomena. Rheology modifiers produce a "three-dimensional" gel network in the continuous phase resulting in a non-Newtonian fluid, which provides stability to the formulation. The rheology modifier must give high viscosity so the product does not separate during long-term storage but still allow the product to be easily poured from the package. The objective of this research was to evaluate a novel polymeric alkoxylate (PA) with carbendazin (500 g/l) for its effect as a rheology modifier on the formulation properties of viscosity, yield point, shear stress, shear thinning, stability, and spray droplet contact angle. PA has been formulated with other surfactants and solvents as a ready-to-use liquid rheology modifier. Formulations with four concentrations of PA formulated as a ready-to-use liquid [0.5, 1.0, 1.5, and 2.0 % weight per volume (w/v)], were evaluated and compared to formulations with four concentrations of a xantham gum (0.05, 0.1, 0.15, and 0.2 % w/v). Formulations with PA performed comparably to xantham gum for viscosity. PA provided desired behavior in shear stress and shear rate studies, and there was little variation in response because of changes in concentration. PA provided a higher yield point than xantham gum. Xantham gum provided stable formulations at all concentrations as measured by bleeding, settling, and particle size distribution. PA provided acceptable formulation stability at concentrations of 1.5 % (w/v) or greater. When diluted in water for field application, formulations containing PA had lower contact angles than xantham gum formulations which will result in improved wettability. PA is classified as a non-eye irritant.

Download or read book Rheology of Dispersions written by Tharwat F. Tadros and published by John Wiley & Sons. This book was released on 2011-07-18 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: A dispersion is a system of unmixable phases in which one phase is continuous and at least one is finely distributed. Examples are found in many industrial applications, including emulsions, suspensions, foams, and geld. The control of their flow characteristics - rheology - is essential in their preparation, long-term physical stability and application. Filling the need for a practical, up-to-date book connecting the stability/instability of the dispersion to its rheological behavior, this title aids in understanding the principles of rheology and the techniques that can be applied. From the contents: * General Introduction * Interparticle Interactions and Their Combination * Principles of Viscoelastic Behavior * Rheology of Suspensions * Rheology of Emulsions * Rheology of Modifiers, Thickeners, and Gels * Use of Rheological Measurements for Assessment and Prediction of the Long-Term Physical Stability of Formulations (Creaming and Sedimentation)

Book excerpt: In the search for new agrochemicals with safe and improved agronomic efficacy in the field, oil dispersion (OD) formulations have been investigated intensively because they are expected to have a better performance on crops than ordinary formulations. This is because the oils and surfactants within the formulation play the role of adjuvants. Therefore, an OD formulation may show a better biological efficacy, making the addition of tank mix adjuvant (regularly used in association with systemic pesticides) optional. The main goal of this work was to develop a new insecticide OD formulation with active ingredients that would be produced as a suspoemulsion (SE), resulting in a better and easier way of formulating a commercial product. These formulations were developed with new surfactants and dispersants and were stabilized using different rheology modifiers, showing appropriate results in stability tests. Rheological assessments were also performed in order to understand system microstructure. The new insecticides' OD formulations also exhibited excellent performance in physical-chemical lab tests and were subjected to field trials with cotton crops at Primavera do Leste, Mato Grosso, Brazil, during the 2012-2013 season. The target insect evaluated in this study was the cotton boll weevil, Anthonomus grandis Boh. (Coleoptera: Curculionidae), which is primarily responsible for damage to Brazilian cotton. The results from using the new OD formulations showed an improved performance when compared to tank mixtures of the same insecticides. Dispersants and rheology modifiers used in this development are promising tools for future OD formulation technology.
