Once purified, the cellulose undergoes a series of carefully controlled chemical reactions. It is first treated with sodium hydroxide to swell the fibers and increase their reactivity. Following this, methyl chloride is introduced to substitute the hydroxyl groups on the cellulose backbone with methyl ether groups, forming methyl cellulose. Subsequently, ethylene oxide is added, which reacts with the remaining hydroxyl groups to introduce hydroxyethyl moieties. This dual substitution yields MHE C-methyl hydroxyethyl cellulose, a compound that combines the water-solubility of hydroxyethyl cellulose with the thermal gelation properties of methyl cellulose This dual substitution yields MHE C-methyl hydroxyethyl cellulose, a compound that combines the water-solubility of hydroxyethyl cellulose with the thermal gelation properties of methyl cellulose
