Products Description
Headcel HEC for controlled release products
HEC has good water solubility, viscosity and thickening properties, which can control the release rate and release pattern of the drug, and is suitable for a variety of drug forms such as tablets, capsules and solutions.
The following factors need to be considered when using a special hydroxyethyl cellulose for slow and controlled release:
- Molecular weight and degree of substitution: these factors determine the physicochemical properties of HEC, such as solubility and viscosity.
- Solubility of the drug: The appropriate concentration and type of HEC needs to be selected based on the solubility of the drug.
- Environmental conditions: such as pH and temperature also affect the performance of HEC and the release of the drug.
