The production of hydroxyethyl cellulose begins with cellulose, which is typically extracted from wood pulp or cotton. This natural polymer needs to undergo a series of treatments to make it suitable for further chemical modifications. The cellulose is first subjected to a process called mercerization, where it is treated with a sodium hydroxide solution. This step increases the reactivity of cellulose by breaking down its crystalline structure, making it more amenable to substitution reactions.

In the construction industry, for instance, MHEC is widely used as a thickener and water retention agent in cement, mortar, and tile adhesives. Its ability to improve workability and extend the open time of these materials makes it a critical component in modern construction practices. Additionally, MHEC also helps to prevent cracking and ensure stronger adhesion, thereby enhancing the durability of construction projects.

Moreover, hypromellose is an essential ingredient in ophthalmic preparations, particularly in eye drops. Its excellent mucoadhesive properties help retain moisture on the eye's surface, alleviating dry eye symptoms. As a result, HPMC has become a preferred choice for the formulation of artificial tears and other ocular solutions.
