Hydroxypropyl methylcellulose is produced by treating cellulose with sodium hydroxide to form alkali cellulose, which is then reacted with propylene oxide and methyl chloride to substitute hydroxyl groups on the cellulose chain with hydroxypropyl and methyl groups, respectively. The final product is then washed, purified, and dried into a powder or granule form.
