- In conclusion, hypromellose (HPMC) is an essential component in the pharmaceutical industry, offering versatility and functionality in various drug formulations. Its precise usage, based on the percentage present, plays a pivotal role in determining the effectiveness and performance of the final product. As research continues to explore new applications and modifications of HPMC, its significance in the pharmaceutical sector is likely to grow even further.
- In the food industry, HPMC is used as a food additive in various products such as sauces, soups, and dairy products
- As a disintegrant, HPMC accelerates the breakdown of the tablet into smaller particles when it comes into contact with moisture. This is essential for ensuring that the active ingredient is released quickly and effectively once the tablet reaches the stomach. HPMC is particularly effective at promoting disintegration in tablets containing drugs that are sensitive to moisture or heat HPMC is particularly effective at promoting disintegration in tablets containing drugs that are sensitive to moisture or heat

- Manufacturers of HPMC play a crucial role in the global market, ensuring consistent quality and supply to meet diverse industry demands. These manufacturers are spread across the globe, with major players situated in countries like China, India, and Europe, where there is an abundance of raw materials and advanced production technologies.
- The pharmaceutical sector is another significant beneficiary of HPMC. It is used as a key excipient in tablets, serving as a binder to hold the tablet together and a disintegrant to ensure rapid dissolution in the stomach. Additionally, it is employed in the formulation of controlled-release drugs due to its ability to form a gel matrix that controls the release rate.
- Conclusion
For hydroxypropyl cellulose (E 463), the identified NOAEL corresponded to the highest dose 6,000 mg hydroxypropyl cellulose/kg bw per day (by gavage). The most relevant feeding studies with HPMC (E 464) were performed in rats which tolerated up to 10%, corresponding to 9,000 mg test item/kg bw per day. Rabbits tolerated up to 7,500 mg HPMC/kg bw per day administered via the diet (30 day exposure) and dogs up to 1,500 mg HPMC/kg bw per day, in either case being the highest tested dosages. More studies were conducted using sodium carboxy methylcellulose (E 466). The most relevant ones were conducted in rats, with NOAEL values ranging from 4,500 to 9,000 mg test item/kg bw per day (in all cases the highest dose tested). In these studies, some effects (caecum and colonic enlargement, urothelial hyperplasia, nephrocalcinosis, diffuse epithelial hyperplasia in the urinary bladder) were observed, however, not considered of toxicological concern: the findings in the gastrointestinal tract were considered to be a consequence of the accumulation of poorly absorbed water-soluble material and the findings in kidneys and urinary bladder were attributed to the up to fourfold higher concentration of sodium in the test diet compared with the basal diet. In one further study, rats were daily exposed (gavage) to doses equivalent to 0, 500, 2,500 or 5,000 mg/kg bw per day. Animals treated with ≥ 2,500 mg/kg bw per day had soft and pale faeces, which was attributed to the presence of test material and not considered of toxicological relevance. In the absence of any other adverse effects, also for this study, the identified NOAEL was the top dose (5,000 mg/kg bw per day).
- Customers should be prepared to provide their name, contact information, and a brief description of their inquiry when calling the HPMC contact number
hpmc contact number. This will enable the customer service representative to better understand their needs and provide timely and accurate assistance.
- Moreover, HPMC imparts improved adhesion to the gypsum plaster
hpmc for gypsum plaster. It allows the plaster to form a stronger bond with various substrates, including brick, wood, and concrete. This enhanced adhesion prevents delamination and prolongs the lifespan of the plaster by resisting the forces that could lead to peeling or flaking over time.
