For all purposes and intent, both types of capsules are used extensively and interchangeably for drug delivery because of their similar properties as finished products.

Yet, their disparate origins often result in some subtle differences between them, like:

6. Heating (If Necessary)

In construction, HEC serves as a crucial ingredient in adhesives, mortars, and sealants. Its thickening and water-retention capabilities improve the workability of these materials, allowing for better performance during application and curing. HEC helps to enhance the adhesion and flexibility of construction materials, ensuring durability and longevity.

3. Organic Solvents While HPMC is primarily water-soluble, the chart also provides insights into its solubility in organic solvents. Grades of HPMC may exhibit varying degrees of solubility in organic solvents like ethanol or methanol, which can aid in the formulation of certain products, especially in the cosmetic or food industries.
