What is Hydroxypropyl Methylcellulose Made Of?
HPMC is a derivative of cellulose, a natural polymer found in plant cell walls. Through a series of chemical processes, cellulose is modified by propylene oxide and chloromethane to form hydroxypropyl methylcellulose. Although synthetic, HPMC retains the essence of cellulose, making it biodegradable and essentially a part of nature.
