HPMC can be described as a semi-synthetic polymer derived from cellulose. It is produced through the etherification of cellulose with propylene oxide and methyl chloride. Due to its unique properties, including film-forming, thickening, and stabilizing capabilities, HPMC has garnered significant interest among formulators. Notably, its non-toxic nature makes it suitable for various applications, including dietary supplements, coatings, and as an excipient in pharmaceuticals.

Personal care products, such as shampoos, conditioners, and lotions, often contain methylcellulose for its thickening and stabilizing properties. It helps to maintain the consistency of these products while providing a smooth feel to the skin and hair.

HPMC is produced by the etherification of cellulose with propylene oxide and methyl chloride. The degree of substitution varies, leading to different molecular weights and rheological properties. On the other hand, HEC is synthesized by reacting cellulose with ethylene oxide, resulting in an ether that provides unique solubility and viscosity characteristics.
