Thermal Degradation of Guar Gum
Information about the thermal degradation of guar gum has been obtained from the time dependence of the viscosity at high temperatures measured using a slit viscometer. The viscosity is related to the molecular weight using previously published relations between the zero shear specific viscosity and the coil overlap parameter in conjunction with the appropriate Mark-Houwink equation. Unlike ani...
متن کاملCarboxymethylation of Guar Gum: Synthesis and Characterization
Recent studies focus on the chemical modification of polysaccharides for biomedical applications. Guar gum is a natural polymer composed of linear chains of (1-4)-β-D mannopyranosyl units with α-Dgalactopyranosyl units attached by (1-6) linkages, in a ratio of about 1.5-2, possessing hydroxyl groups available for the attachment of biologically active compounds. The modifications here discussed ...
متن کاملCationic guar gum polyelectrolyte complex micro particles
Aim: The aim of this study was to organize polyelectrolyte complex microparticles (PECMP) of cationic guar gum and xanthan gum. Materials and Methods: The complex formed was loaded with diclofenac sodium (DS) as a model drug. The prepared microparticles were characterized by Fourier transform infrared spectroscopy (FT-IR), differential scanning colorimetry (DSC), scanning electron microscopy (S...
متن کاملCarboxymethyl guar gum nanoparticles for drug delivery applications: Preparation and preliminary in-vitro investigations.
Carboxymethyl guar gum (CMGG) synthesized from commercially available polysaccharide was formulated into nanoparticles via ionic gelation using trisodium trimetaphosphate (STMP) as cross-linking agent. Characterisation using a range of analytical techniques (FTIR, NMR, GPC, TGA and DLS) confirmed the CMGG structure and revealed the effect of the CMGG and STMP concentration on the main character...
متن کاملStudy of Hydration Kinetics and Rheological Behaviour of Guar Gum
BACKGROUND Guar galactomannan is a plant polysaccharide with extensive applications in food, paper, textile and petroleum industries. The main advantages for using guar are its low cost, easy availability and capacity to form viscous solutions and gels at low concentration. Additionally, chain architecture of guar galactomannan can be selectively modified to tailor properties of guar formulatio...
