Pagkatapos ng alkalisasyon, ang cellulose ay hinaluan ng ethylene oxide (EO), isang reaktibong kemikal na nagdadala ng hydroxyethyl groups. Sa pamamagitan ng pagkokontrol sa temperatura at presyon sa panahon ng reaksyon, ang mga hydroxyethyl groups ay ikinakabit sa cellulose backbone. Ang proseso ng rekomendasyon ay nagsisimula sa mga temperatura sa pagitan ng 40-60 degrees Celsius, at kadalasang tumatagal ng ilang oras, depende sa nais na degree of substitution (DS) ng HEC.

The Chinese MHEC industry has also benefited from the government's supportive policies aimed at promoting chemical manufacturing and export. These initiatives have led to enhanced research and development capabilities, resulting in the production of innovative formulations that cater to the specific needs of diverse sectors. Chinese manufacturers have been successful in producing a range of grades of MHEC, which can vary in viscosity, solubility, and other properties, allowing customers to select products tailored to their specific applications.
