Ashland Benecel HPMC 2910E E4M is a high-quality hydroxypropyl methylcellulose in the Benecel 2910E series. Custom-designed for oral controlled-release formulations and personal care (mainly oral care) products, it meets stringent international pharmacopoeia standards, featuring hydrophilic gel film-forming and efficient foam stabilization, suitable for diverse processing technologies
pH-Dependent Solubility - Insoluble in gastric acid environment, rapidly swells and dissolves in small intestine, achieving intestinal targeted release
Bioavailability Enhancement - As solid dispersion carrier, significantly improves solubility of poorly soluble drugs
Tough Film-Forming Protection - Forms dense and flexible films, blocking gastric acid erosion and ensuring drug stability
Excellent Processing Adaptation - Suitable for aqueous dispersion coating, organic solvent coating and other processes with good flowability
Solid Dispersion Preparation - Used as carrier for solid dispersion of poorly soluble drugs to improve drug dissolution rate
Formulation Enteric Coating - Used for enteric coating of tablets and capsules to achieve intestinal targeted drug release
Intestinal Targeted Formulations - Constructs intestinal targeted delivery systems, protecting bioactive drugs from gastric acid damage
Sustained-Release Matrix - Used as matrix material for sustained-release formulations to regulate stable drug release in intestines
