The study reports on the preparation of nanocrystalline cellulose from waste papers (WPNCC), as an environmental friendly approach source material and investigation their effects morphological, mechanical barrier properties Hydroxypropyl methylcellulose/Cationic starch (HPMC/CS) nanocomposites. HCl hydrolysis followed by alkali treatment deinking fibers resulted in production WPNCC. Also, HPMC/...

Chewable modified release tablets containing two active ingredients vitamin C (200mg) and Sodium Fluoride (2mg) were formulated for the treatment of dental diseases. Other ingredients include Mannitol, Carbopol and Hydroxyl-Propyl Methylcellulose (HPMC), in different ratios. These tablets were prepared by direct mixing of Hydroxypropyl Methylcellulose (HPMC), vitamin C, Sodium Fluoride, Carbopo...

Formulations for sustained medication release are very useful in the treatment of chronic disorders. The oral route has selected matrix tablets as most likely type prolonged drug release. In order to generate therapeutic activity a protracted duration, maintain stable plasma concentration and sustain rate throughout time. preparations with short half-life high dosage frequency, extended-release...

TEMPO (2,2,6,6-tetramethylpiperidine-N-oxyl)-oxidized cellulose nanofibrils (T-CNF) and silver nanowires (Ag NWs) were formulated as active inks. Their rheological properties investigated to design optimal conditions for processing by the screen-printing process, with aim of preparing antibacterial patterns. Rheological experiments mimicking process applied different ink formulations investigat...

This study was conducted to improve the quality and theoretical understanding of gluten-free sorghum bread. The addition of 2% hydroxypropyl methylcellulose improved bread based on 105% water, 70% sorghum flour, and 30% potato starch. Nevertheless, a flat top and tendency toward a hole in the crumb remained. Sourdough fermentation of the total sorghum flour eliminated these problems. Size-exclu...

The objectives of present investigation were to achieve immediate release of paracetamol and tailored release of diclofenac sodium from bi-layer tablets. A 2(3) full factorial design was adopted using the amount of polyethylene glycol, microcrystalline cellulose and crospovidone as independent variables for fabricating paracetamol tablets. Diclofenac sodium tablets were prepared using hydroxypr...

Crystallization of metformin hydrochloride by solvent evaporation method was carried out in the presence of hydrophilic and hydrophobic polymers to investigate the influence of polymer in the agglomeration of the crystallites in–vitro. Transparent, prismatic shaped crystals (of size: 7 × 2 × 1.5 mm3) were crystallized in hydrophilic polymer hydroxypropyl methylcellulose (HPMC) and long rod shap...

The aim of this study was to evaluate binders to improve the flowability of granulates and compactibility of Metformin HCL (Met) using the moist aqueous granulation (MAG) process. The effect of the binder moisture content on granulate and tablet quality was also evaluated. Vinylpyrrolidone-vinyl acetate copolymer (Kollidon VA64 fine: VA64), polyvidone (Povidone K12: PVP), hydroxypropyl cellulos...
