HPMC is a semi-synthetic polymer derived from cellulose, which is a natural polymer obtained from plant cell walls. The basic structure of cellulose consists of linear chains of glucose units linked by β-1,4-glycosidic bonds. To create HPMC, cellulose is modified through chemical reactions involving methylation and hydroxypropylation. The degree of substitution—indicating how many hydroxyl groups on the cellulose backbone are replaced by methyl or hydroxypropyl groups—affects HPMC’s solubility and viscosity.

In pharmaceuticals, CMC is primarily employed as a binder in tablet formulations and as a thickening agent in topical applications like creams and ointments. Its biocompatibility and non-toxic nature make it ideal for use in a broad range of health and beauty products. CMC also acts as an effective dispersing agent in suspensions, ensuring a uniform distribution of API throughout the formulation.
