It is commonly found in personal care products, pharmaceuticals, and food additives due to its ability to form thickening agents, emulsifiers, and stabilizers. If you are looking to buy hydroxyethyl cellulose, there are several options available.
Chemical composition and origin
Hydroxypropyl methylcellulose (HPMC) is produced by treating natural cellulose with methyl chloride and propylene oxide. Cellulose, the basis of HPMC, is an organic compound found in the cell walls of plants, giving HPMC its plant origin. During the production process, hydroxypropyl and methyl groups are added to the cellulose chain. This chemical process improves the solubility of HPMC in cold water and increases its gelation temperature, making it particularly useful in applications requiring thermal stability.
Comparison with other thickeners
Compared to other thickeners such as gelatin, which is of animal origin, HPMC offers a crucial advantage: it is 100% vegetable. This not only makes HPMC suitable for vegetarians and vegans, but also offers significant advantages in terms of stability and shelf life. HPMC is less susceptible to microbial degradation than gelatin, which is especially important for nutritional supplements and medications that require storage in various climates and conditions. In addition, HPMC is resistant to pH fluctuations. While gelatin can break down or lose its effectiveness at different pH levels, HPMC maintains its stability over a wide pH range, making it an excellent choice for formulations that require consistent performance regardless of the acidic or basic conditions in which they are used .- HPMC – type D: high methyl and medium hydroxypropyl content.
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.- In conclusion, methyl hydroxyethyl cellulose (MHEC) is a highly versatile polymer with numerous potential applications across various industries. Its unique properties make it an ideal thickener, stabilizer, film former, and more. As research continues on this fascinating material, we can expect to see even more innovative uses for MHEC in the future.
