Abstract:
Hydroxypropyl methylcellulose in an aqueous solution upon heating tends to undergo thermal gelation, where the polymer chains form a network and precipitate from solution. This occurs at a temperature known as thermal gelation point. Polymer precipitation causes a significant drop in the shear viscosity. This could be a disadvantage in a hot environment or in applications were heat is applied. In this work, a hydroxypropylmethyl cellulose (HPMC) was formed that undergoes thermal gelation with no polymer precipitation and with enhanced rheological properties. The target HPMC was prepared from w

Abstract A collaborative study was performed to determine the reproducibility of a method for the determination of methylcellulose (MC) and hydroxypropyl methylcellulose (HPMC) in food. These widely used food gums possess unusual solubility characteristics and cannot accurately be determined by existing dietary fiber methods. The new method uses the enzyme-digestion procedure of AOAC Official Method 991.43. Digestate solutions must be refrigerated to fully hydrate MC or HPMC. The chilled solutions are filtered and analyzed by size-exclusion liquid chromatography. Collaborating laboratories rec

Purpose – The paper aims to investigate the effectiveness of hydroxypropyl methylcellulose (HPMC) as corrosion inhibitor for aluminium in 0.5 M H2SO4 solution. Design/methodology/approach – This study was carried out using weight loss and electrochemical techniques. Inhibition efficiency was determined by comparing the corrosion rates in the absence and presence of inhibitor system. Quantum chemical computations were performed using density functional theory to assess the parameters responsible for the inhibition process and also to analyse the local reactivity of the molecule.

This study aimed to formulate a gastro retentive slow release dosage form based on oral film for metoclopramide hydrochloric acid (HCl), a medication with a narrow absorption window. The gastroretentive film was made using a solvent casting method with varying ratios of primary polymers (HPMC 15000 cps and HPMC K4M), secondary polymer (carbopol 934), and PEG-400 as a plasticizer. The film of hydroxypropyl methylcellulose (HPMC) K4M-3 (50:50) (HPMC K4M: carbopol) was buoyant for 20 minutes.

This study investigated the frictional properties of HPMC under different load and concentration conditions through friction experiments and surface characterization. The study aimed to explore and reveal the influence of load and concentration on the frictional properties of HPMC, as well as its anti−wear mechanism. The results of the study indicated that under the same solution concentration, the effect of load on the friction coefficient of HPMC was not significant. Specifically, for samples with low concentration (C−0.2), the wear ratio of HPMC under a 4 N load (1.01 × 10−11 mm3·N−1·m−1) w

To examine the flexural toughness characteristics of textile-reinforced lightweight aggregate concrete (TRLC), a four-point bending test was conducted to assess the impact of varying numbers of textile layers and the inclusion of hydroxypropyl methylcellulose on the ultimate load-bearing capacity and deformation capacity of TRLC thin plates. Six groups of specimens were prepared for the experiment, and the bending capacity of the thin plates in each group was evaluated. The flexural toughness index was utilized to quantify the bending performance of TRLC thin plates. The findings revealed that

Hydrophilic polymers in a swellable matrix tablet hydrate quickly to form a hydrogel layer on the exterior of the dosage once in contact with water or biologic fluid. The resultant hydrogel serves as a barrier to regulate water permeation into the matrix and drug diffusion from the preparation. It is therefore important to understand how the polymer is hydrated and what mechanism exists between hydrogel formation and drug dissolution from a swellable matrix tablet.

The shelf life of foods is mostly limited by microbial growth and oxidation reactions. Reducing both these mechanisms by active packaging is an attractive concept to enhance the shelf life. Antimicrobial packages recently developed combine natural antimicrobial compounds like carvacrol and isothiocyanates with biobased polylactic acid (PLA) films. Antioxidant packaging can be used to further improve product quality and extend the shelf life of food by free radical scavenging.

As a coating on granular foods, FHSBO also prevents undesirable interactions between the coated granules and other components in the product matrix. However, during mixing processes, impact from the mixer impellers and abrasion from the other ingredients can lead to chipping or wear on FHSBO coatings, which lowers the quality of the finished products.
