Pill capsule is one of the most important ways for people to take oral drugs over the last hundred years, and gelatin becomes the first choice for capsule materials because of its low price and stable chemical and physical properties. As the wide usage of the gelatin, some of its problems were gradually revealed. On the one hand, because early gelatin is often made from the bone and skin of cattle and pigs, many diseases are thought to be easily transmitted by gelatin capsule, such as mad cow disease (bovine spongiform encephalopathy). And these ingredients may be unacceptable to vegetarians, Jews, Islamists or Hindus. On the other hand, the development of various New Chemical Entity causes more requirements for using gelatin capsules. For example, some substances containing aldehyde groups may cause a cross-linking reaction of gelatin, and with strong reducing substances, the gelatin will cause Mailard Reaction, and so on. Therefore, many experts started to look for a new alternative for capsule material, which would be safer and healthier. HPMC (HYDROXYPROPYL METHYLCELLULOSE) is one of the suitable alternatives, and then it comes out HPMC capsule.

Dow Chemical, for instance, provides a range of products under the Cellosize brand. You can access detailed information, product data sheets, and even technical support on their official website.
There are a few blogs and sites pushing scare stories regarding the heavy metals found in HPMC. The heavy metals present in our HPMC are tested and certified at a level of under 10 parts per million. This is significantly below the threshold of what might be considered unsafe for human consumption. Again, it's worth noting that heavy metals are all around us and when consumed in small doses, are perfectly safe - our bodies naturally filter them out. They are found in fish, greens, brown rice and more. To clarify, we are not saying that the consumption of heavy metals is a particularly good thing, just that any form of panic or hysteria regarding the consumption of minuscule amounts of them is not helpful. For example - there is more mercury in fresh tuna than there is in HPMC. That is the very same tuna that is prized in Japanese cuisine - a country which had the second highest life expectancy in the world in 2018.
Viscosity is a measure of a fluid's resistance to flow, and for HEC, it is crucial in determining how the substance will behave in various formulations. The viscosity of HEC solutions can vary significantly based on several factors its molecular weight, concentration, and temperature. Generally, as the concentration of HEC increases, the viscosity of the solution also rises. This is due to the interactions among the polymer chains, which lead to an entangled network in the solution.
