Additionally, research indicates that HPMC is non-toxic, non-irritating, and biodegradable. Studies have shown that HPMC does not exhibit genotoxicity or carcinogenicity, further supporting its safety profile. The polymer is often used in products intended for oral ingestion without adverse effects, making it an appealing choice for formulation developers.
In the context of HPMC, the term “high viscosity” is relative and context-dependent. Generally, the industry recognizes HPMC with viscosity values above 100,000 mPa·s as high viscosity. It is important to note that 100,000 mPa·s may be a high viscosity value for one application, but 100,000 mPa·s may be a standard viscosity or even a low viscosity for another application. Although we mentioned above that there is a range of viscosities, the so-called high and low viscosities need to be compared to a corresponding application.
- In conclusion, there are several options available for purchasing hydroxyethyl cellulose. Whether you choose to buy online, through a chemical supply company, from a specialty store, or at a local hardware store, make sure to do your research and select a reputable seller. With a little effort, you can easily find the HEC you need for your projects or applications.
