About Hydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl Methylcellulose (HPMC), also known as hypromellose, is a semisynthetic, inert, and viscoelastic polymer derived from cellulose. Its chemical formula is variable due to the degree of substitution and molar substitution on the cellulose backbone, but it is commonly represented as C₅₆H₁₀₈O₃₀. HPMC typically appears as an off-white to beige powder that forms colloidal solutions when dissolved in water. Industrial production involves the etherification of cellulose with methyl and hydroxypropyl groups, resulting in a compound with versatile properties. HPMC is widely utilised across various sectors, including construction, pharmaceuticals, food, personal care, and ceramics.

Hydroxypropyl Methylcellulose Uses

Construction Industry

In the construction sector, HPMC serves as a vital additive in products like tile adhesives, cement renders, and gypsum-based materials. It acts as a thickener, water retention agent, and improves workability, ensuring enhanced performance and durability of construction materials.

Pharmaceutical Applications

HPMC is extensively used in the pharmaceutical industry as an excipient in oral tablets and capsules. It functions as a binder, film-former, and controlled-release agent, aiding in the effective delivery of active pharmaceutical ingredients. Additionally, its mucoadhesive properties make it suitable for oromucosal delivery systems, including mucoadhesive tablets and films.

Food Industry

As a food additive, HPMC acts as an emulsifier, thickener, and stabiliser. It is employed in various food products to improve texture, consistency, and shelf-life. Notably, HPMC serves as a vegetarian alternative to gelatin in food applications.

Personal Care Products

In personal care and cosmetic products, HPMC functions as a thickening agent, film-former, and emulsifier. It is commonly found in products such as shampoos, lotions, and creams, enhancing their viscosity and stability.

Ceramics Industry

HPMC is utilised in the ceramics industry as a binder and plasticiser. It improves the workability of ceramic formulations, aids in shaping processes, and enhances the mechanical strength of green bodies before firing.
