Hydroxypropyl Methylcellulose (HPMC) is a semi-synthetic compound derived from cellulose, which is a naturally occurring polymer found in the cell walls of plants. HPMC is produced through a chemical modification process where cellulose, typically sourced from wood pulp or cotton fibers, is reacted with propylene oxide and methyl chloride.

While the starting material for HPMC is natural (cellulose), the modification process involves the use of chemicals, making it a semi-synthetic substance. The purpose of the chemical modification is to introduce hydroxypropyl and methyl groups onto the cellulose backbone, resulting in the desired properties and functionalities of HPMC.

HPMC retains some of the characteristics of natural cellulose, such as water solubility and biodegradability, while offering improved performance and versatility compared to unmodified cellulose. Its semi-synthetic nature allows for precise control over its properties, such as viscosity, gelation, and film formation, making it suitable for various applications in industries like pharmaceuticals, food, cosmetics, and construction.

It's worth noting that the specific manufacturing processes and the quality of HPMC can vary among manufacturers. Therefore, it's important to ensure that the HPMC used in a specific product meets the necessary quality standards and regulatory requirements.
