Nano-silica/hydroxypropyl methyl cellulose nanocomposite

Hydroxypropyl methylcellulose (HPMC) is found better thickening and suspending properties to prevent sedimentation problems when used for water-based drilling fluid, and it shows better solubility at room temperature when surface modified to instant hydroxypropyl methylcellulose polymer.

Effect of HPMC Concentration Variation as Gelling Agent on

HPMC is a gelling agent that belongs to the semi-synthetic polymer group and is widely used as an excipient in topical dosage formulations. When compared with other gelling agent, HPMC produces clearer, neutral, colorless, tasteless liquids, produces gels with good viscosity in long-term, non-toxic, storage and does not irritate the skin.

Hydroxypropylmethylcellulose - an overview | ScienceDirect Topics

Hydroxypropyl methylcellulose (HPMC) or hypromellose refers to soluble methylcellulose ethers. HPMC is used as a thickening agent, binder, film former, and hydrophilic matrix material. HPMC polymers for fabricating hydrophilic matrix systems are available in various viscosity grades ranging from 4000¨C100,000 mPa s.

Cellulose sent to TAP reviewers k2

119 HPMC has many pharmaceutical uses, as a drug carrier, a coating agent, a tabletting agent, an emulsifier in ointments 120 (Greminger, 1973). It is also used in ophthalmic solutions (Robert, 1988, USP 1995) and as a slow release agent. It is 121 widely used in personal care products as a thickening agent and foam stablizer (Dow, 2002). 122

Hydrocolloids as thickening and gelling agents in food: a

Hydrocolloids are a heterogeneous group of long chain polymers (polysaccharides and proteins) characterised by their property of forming viscous dispersions and/or gels when dispersed in water. Presence of a large number of hydroxyl (-OH) groups markedly increases their affinity for binding water molecules rendering them hydrophilic compounds.
