Numerous online platforms provide detailed insights into its chemical properties, application methods, and safety data. Websites dedicated to the chemical and pharmaceutical industries offer extensive databases that outline the various grades of HPMC available, along with their specific functions.
The CIR Expert Panel noted that in addition to the use of the cellulose ingredients in cosmetics and personal care products, they were widely used in food, pharmaceuticals and industrial products. Large doses of Methylcellulose and Cellulose Gum administered orally as laxatives produced no toxic effects in humans. The cellulose derivatives pass essentially unchanged through the gastrointestinal tract following oral administration. They are practically nontoxic when administered by inhalation or by oral, intraperitoneal, subcutaneous, or dermal routes. Subchronic and chronic oral studies indicated that the cellulose derivatives were nontoxic. No significant developmental or reproductive effects were demonstrated. Ocular and dermal irritation studies showed that the cellulose derivatives were minimally irritating to the eyes and nonirritating to slightly irritating to the skin when tested at concentrations up to 100%. No mutagenic activity of these ingredients was demonstrated.
In tablet formulations, HPMC serves multiple functions. It acts as a binder, ensuring the cohesion of granules during compression, which is crucial for maintaining tablet integrity. Additionally, HPMC can function as a disintegrant, promoting the breakdown of tablets in the gastrointestinal tract and thereby enhancing drug absorption. When used in controlled-release tablets, HPMC creates a gel-like barrier around the drug, allowing for a slow and continuous release of the active pharmaceutical ingredient (API) over time. This is particularly beneficial for drugs that require long-term therapeutic effects with minimal side effects.
