Dialyzability of Surfactants Commonly Used in Pesticide Formulations
Objective: This study aimed to determine the dialyzability of common pesticide surfactants. Methods: Hemodialysis and hemoperfusion were performed for three surfactants-sodium dodecylbenzenesulfonate, lignosulfonic acid sodium, and naphthalenesulfonic acid polymer with formaldehyde-with buffer solutions (2 L) containing 0.2% surfactant with or without bovine serum albumin (3.0 g/dL). Results: T...
متن کاملApplication of lactobionic acid and nonionic surfactants as solubilizing agents for parenteral formulation of clarithromycin.
PURPOSE The purpose of this paper is to enhance the solubility of clarithromycin (CLR) using nonionic surfactants and some type of acids for preparation of the new formulations. METHODS Myrj 52 and chremophor (2.5 and 5% w/v) were used in two concentrations. To investigate solubility, the formulations were shaken for 48 hours at room temperature. For stability test, lyophilized samples were m...
متن کاملPhysicochemical Characterization of Nonionic Surfactants in oil-in-water (O/W) Nano-emulsions for New Pesticide Formulations
Physicochemical characteristics of pre-formulation concentrates of an emulsion system of LFAMEs/APG:organosilicone/water were determined. The surfactants used were octyl/decyl polyglucosides (short-chain APG; SAPG) and dodecyl/tetradecyl/hexadecyl polyglucosides (long-chain APG; LAPG). Alkyl chain length of the APG was found to dominate the different flow behaviours of emulsions. The SAPG-emuls...
متن کاملMicrobial surfactants: fundamentals and applicability in the formulation of nano-sized drug delivery vectors.
Microbial surfactants, so-called biosurfactants, comprise a wide variety of structurally distinct amphipathic molecules produced by several microorganisms. Besides exhibiting surface activity at the interfaces, these molecules present powerful characteristics including high biodegradability, low toxicity and special biological activities (e.g. antimicrobial, antiviral, anticancer, among others)...
متن کاملThermodynamic Analysis for Cationic Surfactants Binding to Bovine Serum Albumin
In the present study, the binding isotherms for interaction of a homologous series of n-alkyltrimethyl ammonium bromides with bovine serum albumin (BSA) have been analyzed on basis of intrinsic thermodynamic quantities. In this regards, the intrinsic Gibbs free energy of binding, AGb(i,)„ has been estimated at various surfactant concentrations and its trend of variation for both binding sets ha...
