HPMC online is more than just a platform; it's a catalyst for educational transformation, empowering students and researchers worldwide with unprecedented access to advanced computational tools and resources.

HPMC-Kapseln sind nicht magensaftresistent, das bedeutet, sie lösen sich bereits im Magen auf und geben so die Inhaltsstoffe frei.

Magensaftresistente Kapseln können zwar ebenfalls aus HPMC bestehen, sie sind aber zusätzlich noch mit synthetischen Stoffen überzogen, die der Magensäure standhalten. Die Idee hinter solchen Kapseln ist, dass sie sich im Dünn- bzw. Dickdarm auflösen und dort erst die Inhaltsstoffe freigeben. Dies ist dann sinnvoll, wenn bspw. das saure Milieu des Magens die Wirkstoffe zerstören würde. Die Einnahme solcher Kapseln sollte aber immer mit dem behandelnden Arzt bzw. der Ärztin abgesprochen werden, da die Anwendung genau beachtet werden muss.

Gelation temperature refers to the temperature at which a solution or dispersion changes from a liquid to a gel-like state. This transition is crucial for the stability and functionality of many products, including pharmaceuticals, food, and personal care products. HPMC plays a significant role in controlling the gelation temperature by affecting the interaction between the polymer chains and the solvent molecules.

One of the most significant applications of redispersible polymer powder is in the production of cement-based products. When added to cement, it significantly improves the workability, strength, and durability of the final product. This is because the polymer particles act as a filler, reducing the amount of water needed in the mixture, which in turn reduces the risk of cracking and shrinkage. Additionally, the polymer particles enhance the bonding between the cement grains, leading to improved mechanical properties.

Another significant advantage of VAE redispersible powder is its ease of use. The powder can be easily mixed with water to form a smooth, uniform dispersion, eliminating the need for complex mixing equipment or skilled operators. This simplifies the application process and reduces the risk of errors or inconsistencies in the final product.

Moreover, HPMC finds applications in the paint and coatings industry as a rheology modifier, improving flow properties and preventing sagging during application. It is also used in printing inks for its film-forming properties and in paper manufacturing to enhance the strength and printability of the final product.

7. Store the Solution Once you have achieved the desired consistency, store the HPMC solution in an airtight container at room temperature. Avoid storing the solution in direct sunlight or near heat sources, as these can cause the HPMC to degrade over time.

There are data for microcrystalline cellulose (E 460), methyl cellulose (E 461), hydroxypropyl cellulose (E 463) and sodium carboxymethyl cellulose (E 466), which were tested in mice, rats, hamsters and/or rabbits with oral dosing or via gavage. As regards microcrystalline cellulose (E 460) studies have been conducted in rats (dietary exposure) with a mixture including guar gum or sodium carboxymethylcellulose (E 466) (15% in either case). The NOAEL for both maternal and developmental toxicity were the highest experimental dosages, i.e. 4,500 mg/kg bw (for mixture with guar gum) and 4,600 mg/kg bw (for mixture with sodium carboxymethyl cellulose). Methyl cellulose (E 461) was examined in mice, rats, hamsters and rabbits. In two different studies, pregnant mice were exposed via gavage (vehicle corn oil) to a dose range of 16-1,600 mg methyl cellulose (E 461)/kg bw per day from day 6 to 15 of gestation, followed by a caesarean section at day 17 of gestation. In the first study, maternal toxicity (increase in mortality and reduced pregnancy rate in the survivors) as well as retarded ossification in fetuses were noticed at the highest tested level, pointing to a NOAEL of 345 mg methyl cellulose (E 461) mg/kg bw per day (the last but one highest dosage) in mice. In the second study, no maternal toxicity and fetal abnormalities were observed in mice exposed up to 700 mg methyl cellulose (E 461) mg/kg bw per day. Rat studies (n = 2) were performed in pregnant dams exposed via gavage (vehicle corn oil) to a dose range of 16-1,320 mg methyl cellulose (E 461) mg/kg bw per day from day 6 to 15 of gestation followed by a caesarean section at day 20. In the first study (0, 13, 51, 285 or 1,320 mg methyl cellulose (E 461)/kg bw per day) the highest tested dosage resulted in no maternal toxicity but also in increased incidence of extra centres of ossification in vertebrae of fetuses from high dose dams; in a second rat study, the incidence of such alteration slightly increased in fetuses from the highest dosed group (1,200 mg methyl cellulose (E 461)/kg bw per day). Based on the above results, a NOAEL of 285 mg methyl cellulose (E 461) mg/kg bw per day could be identified in rats. No maternal or fetal toxicity was detected in Golden hamsters exposed via gavage (vehicle corn oil) up to 1,000 mg methyl cellulose (E 461) mg/kg bw per day from day 6 to 10 of gestation followed by a caesarean section at day 20. The study on rabbits was discarded due to poor experimental design. The only relevant developmental toxicity study with hydroxypropyl cellulose (E 463) (dissolved in 1% gum arabic solution) was performed in pregnant rats exposed via gavage from day 7 to 17 of gestation to 0, 200, 1,000 or 5,000 mg/kg bw test item and some of them subjected to caesarean sections at day 20. No treatment-related adverse effects were detected in dams or in the examined fetuses. A number of dams were allowed to deliver and no clinical, behavioural or morphological changes were observed in the examined pups. Their reproductive ability was seemingly not affected and no abnormalities were found in the F1-derived fetuses. The in utero exposure to the highest dose (5,000 mg/kg bw per day) may be considered as the NOAEL of methyl cellulose (E 461) for this study. No mortality, and no adverse effects were observed on implantation or on fetal survival in pregnant mice or rats dosed via gavage with up to 1,600 mg sodium carboxymethyl cellulose (E 466)/kg bw per day.

Moreover, redispersible polymer powder offers significant improvements in workability and water retention

In the rabbit hindgut, fermentation occurs through a wide prevalence of Bacteroides that do not allow an extended digestibility of fibre. Digestibility of cellulose was shown to amount to 16% of the administered dose, whereas values of 14% and 18% were reported for fibre (cellulose being the main component) (review from the NRC, 1977). Later studies reported values comprised between 15 and 25% in rabbits administered different plant sources of cellulose (Gidenne and Perez, 1996; Chiou et al., 1998). In the horse, digestion of plant structural carbohydrates (including cellulose) occurs in the hindgut (colon and overall caecum). The microbiota of the caecum comprises bacteria similar to those of the rumen, but specific protozoa. The resulting digestibility is about two-third that measured in ruminants.

In the food industry, HEC is used as a stabilizer and thickening agent in a variety of products, including sauces, dressings, and dairy products. It helps to improve the texture, mouthfeel, and overall sensory properties of these foods. HEC is also often used in low-fat or fat-free products to mimic the mouthfeel and texture of full-fat versions.

In the construction industry, hydroxyethylcellulose is commonly used in cement-based products such as tile adhesives, grouts, and mortars. It acts as a thickening agent and helps to improve the workability and consistency of these products. Additionally, HEC is used as a protective colloid in cement slurries, where it helps to prevent sedimentation and improve stability.
