Understanding the chemical underpinnings of an ingredient is vital for optimizing its use in product development. Hydroxypropyl Cellulose (HPC), a derivative of cellulose with the CAS number 9004-64-2, is a prime example of how molecular structure translates to diverse functionalities. NINGBO INNO PHARMCHEM CO.,LTD., as a leading chemical supplier, is dedicated to providing HPC that meets precise scientific and industrial demands.

HPC is synthesized through the etherification of cellulose, where hydroxyl groups on the cellulose backbone are substituted with hydroxypropyl groups. This modification introduces both hydrophilic (ether linkages and hydroxyl groups) and slightly hydrophobic (propylene backbone) characteristics. Crucially, the degree of substitution and molar substitution dictate HPC's solubility and thermal behavior. Most HPC exhibits a lower critical solution temperature (LCST) around 45°C, meaning it is soluble in water below this temperature but precipitates out upon heating, a reversible process.

This unique thermal solubility profile makes HPC valuable in applications requiring controlled viscosity changes. In pharmaceuticals, this can influence drug release rates, while in cosmetics, it can affect product texture and spreadability. For formulators looking to buy ingredients with predictable thermal responses, HPC is a compelling choice. As a manufacturer, we ensure consistent molecular weights and substitution levels for reliable performance.

The polymer chain length and branching, influenced by the manufacturing process, also contribute to HPC's thickening capabilities. Its ability to hydrate and form viscous solutions makes it an effective thickener, emulsifier, and stabilizer in a wide range of formulations. Companies seeking to purchase high-performance thickeners for their products will find HPC to be an advantageous ingredient.
