                                Hypromellose, also known as HPMC, is derived from cellulose, the most abundant organic polymer on Earth found in plant cell walls. While its origin is plant-based, the key question remains: is hypromellose natural, or is it a chemically altered substance? It is actually considered a semi-synthetic compound.
