hydroxy methyl cellulose. HMC is valued for its ability to act as a binder, thickener, and stabilizer in these formulations, helping to ensure that the active ingredients are evenly distributed and that the product remains stable over time. HMC is also used as a film-forming agent in oral drug delivery systems, helping to control the release of the active ingredient in the body.2. HPMC produced
- In the cosmetic industry, HEC serves as an emulsifier and stabilizer, ensuring the uniform mixing of oil and water-based ingredients. It is commonly found in shampoos, conditioners, and lotions, where it improves texture and gives products a rich, creamy feel. Additionally, it acts as a rheology modifier, controlling the flow and spreadability of these formulations.
- Understanding HPMC Viscosity Table
- The first distinction among HPMC types lies in their substitution pattern. The ratio of hydroxypropyl (HP) to methyl (M) groups varies, affecting solubility and gel strength. Low-viscosity HPMC, with a higher proportion of HP groups, tends to be more soluble and is often used for immediate-release formulations. In contrast, high-viscosity HPMC, rich in M groups, provides a stronger gel network, making it suitable for extended-release applications.
