What is HPMC?

Purchasing Hydroxyethyl Cellulose

After the emulsion is formed, it must be converted into a powder. This is typically achieved through drying techniques, with spray drying being one of the most common methods. In spray drying, the emulsion is atomized into fine droplets and passed through a hot air chamber. As the droplets travel through the chamber, the water evaporates rapidly, leaving behind a fine powder of polymer particles. Alternatively, other drying methods such as freeze-drying or drum drying can also be applied, depending on the specific requirements of the product.
