Gelatin Capsules

In conclusion, Hydroxypropyl Methylcellulose (HPMC) is not just another polymer — it is a crucial element that serves diverse industries through its unique properties. As research and technology advance, the potential applications of HPMC are likely to expand further, solidifying its role as a vital component in the future of materials science and product formulation.

HPMC, a versatile cellulose ether derived from natural plant fibers, exhibits a wide range of viscosities. The viscosity of HPMC is typically measured using a solution in water at a specific concentration and temperature. The viscosity is often expressed in terms of centipoise (cP) or mPa·s (millipascal-seconds).

For all purposes and intent, both types of capsules are used extensively and interchangeably for drug delivery because of their similar properties as finished products.

Yet, their disparate origins often result in some subtle differences between them, like:

The production of HPMC powder generally involves several steps. It begins with the extraction of cellulose from wood pulp or cotton. The cellulose is then chemically modified through etherification, where hydrochloric or sulfuric acid is used as a catalyst to introduce hydroxypropyl and methyl groups. The resulting product is then dried and milled to obtain a fine powder.
