Hydration of Hydroxypropylmethyl Cellulose: Effects of pH and Molecular Mass
Magnetic resonance imaging was used to study the diffusion of a water solution of hydrochloric acid (HCl) and sodium hydrochloride (NaOH) into hydroxypropylmethyl cellulose matrices. Polymer in the form of a cylinder was hydrated in a water solvent of pH = 2, 7, and 12 at 37◦C and monitored at equal intervals with a 300 MHz Bruker AVANCE. The spatially resolved spin–spin relaxations times and s...
متن کاملSans Studies of Liquid Crystalline Microemulsion Gels
We have investigated by small-angle neutron scattering (SANS) the ternary system containing water, alkane and the surfactant mixture benzyltetradecyldimethylammonium chloride and tetradecyltrimethylammonium bromide, which we have found to form a cubic liquid crystalline phase. A contrast variation experiment with equal volume fractions of water and oil showed three Bragg reflections varying in ...
متن کاملBiocompatible microemulsion systems for drug encapsulation and delivery
This review of biocompatible lipophilic drug encapsulating and delivery systems entails the basics of colloidal drug delivery with special reference to oil-in-water microemulsion. The behaviour of the biocompatible systems, their formulation and ingredients, physicochemical properties, applications through different routes, advantages and restrictions therein have been presented. In vitro and i...
متن کاملAggregation and gelation in hydroxypropylmethyl cellulose aqueous solutions.
In this work we present an analysis of the thermal behavior of hydroxypropylmethyl cellulose aqueous solutions, from room temperature to higher temperatures, above gelation. We focus on significant aspects, essentially overlooked in previous work, such as the correlation between polymer hydrophobicity and rheological behavior, and the shear effect on thermal gelation. Micropolarity and aggregat...
متن کاملRespiration Rate of Cherry Tomatoes and Gas Permeability of Hydroxypropylmethyl Cellulose-Based Coating
The aim of this study was to measure the gas permeability of edible films using a homemade experimental apparatus and to determine the respiration rate of tomatoes (L. esculentun var. Cerasiforme) without (NC) and with (CC) edible coating at different temperatures. Permeability was determined using an experimental device according to the ASTM D1434 method and the apparatus was validated using p...
