The development of liquid crystal materials via nanotechnology has become an interesting subject research in optical material chemistry. One the significant nanomaterials is cellulose-based nanoparticles. In this review article, we highlighted classification (LCs), and types cellulose-NPs their characterization as LCs materials. Finally, present our promising data on synergistic effect behavior...

The current study deals with the synthesis of novel hydroxypropyl methyl cellulose acrylate (HPMCAA) by the process of esterification of hydroxypropyl methyl cellulose and acryloyl chloride. The polymers were characterized by FTIR spectrophotometry, DSC, XRD and haemocompatibility studies. The microstructures of the HPMC and HPMCAA powders were studied under a scanning electron microscope. The ...

The incremental elimination or hydroxy functionality in an organosolv lignin by ethylalion or acetylation dramatically innuenced the state of miscibility and resulting morphology or blends prepared with hydroxypropyl cellulose (HPC). A maximum level of interaction between the blend components, as determined from melting point depression, oa:.urred where 23-40-1. or the hydroxy groups were subst...

In present study, mucoadhesive vaginal tablet of sertaconazole was designed using a combination of mucoadhesive polymers like Carbopol 934P, chitosan, carboxymethylcellulose sodium, sodium alginate, methyl cellulose, hydroxypropyl methylcellulose and hydroxypropyl cellulose. Effervescent was incorporated into formulations to enhance swellabilty of mucoadhesive tablet. For various drug-free form...

DESCRIPTION LOPID (gemfibrozil tablets, USP) is a lipid regulating agent. It is available as tablets for oral administration. Each tablet contains 600 mg gemfibrozil. Each tablet also contains calcium stearate, NF; candelilla wax, FCC; microcrystalline cellulose, NF; hydroxypropyl cellulose, NF; hypromellose, USP; methylparaben, NF; Opaspray white; polyethylene glycol, NF; polysorbate 80, NF; p...

The aim of this work was to investigate the effects of the nature and concentration of cellulose derivatives on the release kinetics of ibuprofen from hydrogel matrices using a response surface method (RSM). A series of cellulose derivatives, as methyl, hydroxyethyl, hydroxypropyl and hydroxypropyl methyl celluloses (MC, HEC, HPC and HPMC) were used as polymer platforms and their impacts on dru...

Mucoadhesive microbeads of low methoxyl pectin were prepared, either alone or in combinations with hydroxypropyl methyl cellulose, sodium carboxymethyl cellulose, methyl cellulose and carbopol 934P, by ionotropic gelation. The influence of copolymers on mucoadhesivity, microbeads characteristics and in vitro drug release was investigated. Spherical microbeads with 78.69±0.59 to 85.84±0.78% drug...

A short review with 49 references describes the electrospinninng (ES) process for polysaccharides, cellulose and chitosan, and their derivatives, including cellulose acetate and hydroxypropyl cellulose. A majority of applied studies adopted a two step-process, in which the cellulose acetate was used for the first ES process, followed by acetyl group removal to regenerate cellulose thin fibers. ...

Cellulose etherification with 3-chloro-2-hydroxypropyl-trimethylammonium chloride (CHPTAC) was carried out in NaOH/urea aqueous solution, under homogeneous conditions. The substitution degree of the prepared quaternized cellulose, cellulose-CHPTAC, increased with increasing molar ratio of CHPTAC/anhydroglucose unit (AGU), reaction temperature, and reaction time. The structure of the cellulose-C...
