- For a long time, the only material used to make capsule shells was gelatine. Gelatine is obtained from the skin and bones of various animal species, especially pigs and cattle. Due to strict regulations on the use of gelatine caused by emerging diseases such as TSE (Transmissible Spongiform Encephalopathy), which includes BSE (Bovine Spongiform Encephalopathy), the search for a substitute for gelatine was encouraged.
Plant-based capsules have also been available on the market since 1998. With HPMC, consumers have a completely safe, plant-based product at their disposal, so that vegans or vegetarians and people who abstain from gelatine due to their religion also have an alternative to gelatine capsules.
HPMC capsules can withstand high temperatures and high humidity and have a low inherent moisture content. This makes the capsule shells suitable for storing moisture-sensitive ingredients. They therefore protect their contents from all kinds of fluctuations, such as temperature fluctuations and humidity. HPMC capsules can therefore be stored well in all climate zones. In contrast, gelatine capsule shells have a lower water content. They therefore quickly become brittle at low humidity.
Despite the many advantages of HPMC capsules, gelatine capsules are still the most commonly used type of capsule in the pharmaceutical industry. One reason for this is probably the lower price. - 3.

- HPMC is a chemically modified cellulose derivative that is water-soluble and has a high degree of stability. It is commonly used as a thickening agent, stabilizer, and emulsifier in many products. Its ability to form transparent gels makes it a popular choice in pharmaceuticals for coating tablets and controlling drug release.
- Another crucial factor influencing HEC prices is the cost of raw materials. Cellulose, the primary ingredient, is sourced from wood pulp or cotton lint, both of which are subject to seasonal and regional variations. Unpredictable weather conditions can lead to a scarcity of these resources, pushing up the production cost and affecting HEC prices.
- In the realm of pharmaceutical manufacturing, the role of Hydroxypropyl Methylcellulose (HPMC) cannot be overstated. This versatile polymer serves as a critical component in a range of formulations, from tablets to capsules and even topical applications. Its popularity stems from its ability to act as a binder, thickener, and disintegrant, among other functions. However, understanding the nuances between different types of HPMC is crucial for optimizing its performance in various formulations.

- In pure water, HEC generally forms a clear, viscous solution at room temperature. The rate of dissolution depends on factors such as particle size, concentration, and temperature. Smaller particles dissolve more rapidly, while increasing temperature can enhance solubility by reducing the viscosity of water and increasing the kinetic energy of the molecules.
- Next, prepare a vessel filled with tepid water—water that is too hot can degrade the polymer, while cold water will not facilitate efficient wetting. It is recommended to use a temperature around 20°C to 25°C for optimal results. The quantity of water needed will depend on the desired concentration of the HPMC solution, but generally, using more water than you think is necessary will help in preventing clumps.
- The use of HPMC in mortar formulations also offers economic benefits. Despite its additional cost, it can reduce the overall consumption of cement and sand, thereby offsetting the extra expense. Moreover, the improved workability and strength can lead to faster construction, reduced labor costs, and potentially longer lifespan of structures.

In repair mortars, it enhances crack resistance and flexibility, thereby prolonging the life of the structure. Moreover, in the production of external thermal insulation composite systems (ETICS), redispersible powders contribute to better mechanical properties and weather resistance.
HPMC and HEC, both of them are a kind of cellulose ether. but what is the difference between them? HPMC VS HEC. In recent years, the output and consumption of HPMC have been increasing rapidly. HPMC is an ironic cellulose ether. it begins refined cotton after alkalization treatment. Propylene oxide and methyl chloride is the etherifying agent in the HPMC manufacturing process. After a series of reactions, get HPMC. But HEC also begins refined cotton after alkalization treatment. With acetone, HEC uses ethylene oxide as the etherifying agent. So HEC has more hydrophilic than HPMC. It is prone to absorb moisture.
