Once the cellulose is in its alkali form, it is treated with ethylene oxide in a controlled environment. The etherification process introduces hydroxyethyl groups to the cellulose chains, resulting in hydroxyethyl cellulose. The reaction conditions, including temperature, concentration of reactants, and reaction time, are carefully controlled to regulate the degree of substitution (DS) of the hydroxyethyl groups. A higher DS often leads to improved solubility and thickening properties, making it essential to optimize this parameter according to the intended application of the HEC.

In the pharmaceutical industry, HPMC serves multiple roles. It is commonly used as a binder and film-coating agent in tablet formulations, enhancing drug stability and releasing the active ingredients in a controlled manner. HPMC's ability to create viscous gels makes it a suitable excipient for sustained-release formulations, enabling more effective drug delivery.

In the realm of personal care, HPMC is commonly used in the formulation of cosmetics and toiletries. Its thickening and film-forming properties contribute to the overall texture and user experience of products such as lotions, shampoos, and conditioners. Moreover, HPMC is known for its ability to enhance the spreadability of these formulations, allowing for a smoother application on the skin or hair. The versatility of HPMC in the beauty industry underscores its ability to adapt to diverse formulation needs.
