In the construction industry, HEC is used in cementitious products, while in oil & gas, it serves as a drilling fluid additive. A rise in infrastructure projects or drilling activities can increase the demand for HEC, pushing up its price.
- Another contributing factor to HEC's thickening mechanism is the formation of 'secondary structures
hydroxyethyl cellulose thickening mechanism.' In aqueous solutions, HEC chains can associate through van der Waals forces or hydrogen bonding, forming aggregates or micelles. These secondary structures further enhance the viscosity by restricting the free movement of water molecules and increasing the internal friction within the solution.
- Moreover, HPMC's excellent film-forming characteristics enable its use in film coating processes. Film coating is crucial for improving the appearance, stability, and patient compliance of solid oral dosage forms. HPMC films provide a smooth and uniform coat, protecting the drug from environmental factors such as moisture and light while masking any unpleasant tastes.
- Hydroxypropyl methylcellulose (HPMC) is a versatile and widely used ingredient in a variety of industries. It is a synthetic derivative of cellulose, which is a natural polymer found in plant cell walls. HPMC is commonly used in the construction, pharmaceutical, food, and cosmetic industries for its unique properties.
- In the cosmetics industry, HEC is a popular choice for its non-toxic and non-irritating nature
- Hydroxyethyl cellulose (HEC), a chemical derivative of cellulose, is a non-ionic, water-soluble polymer that has found extensive use in a myriad of industries due to its unique properties. Its versatility stems from its ability to form stable solutions in cold and hot water, its non-toxic nature, and its ability to thicken, suspend, emulsify, and stabilize various substances.
- Both HPMC and CMC have their unique attributes, but when used in combination, they can create synergistic effects that optimize drug delivery systems. For instance, in oral solid dosage forms, HPMC can control the release rate of the drug, while CMC can ensure the tablet disintegrates properly, facilitating absorption. This collaboration results in a more efficient and reliable therapy for patients, enhancing compliance and overall treatment outcomes.
(6) Polyvinyl chloride: As dispersant in the production of polyvinyl chloride, it is the main assistant in the preparation of PVC by suspension polymerization.
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.Visual density: 0.25-0.70g/cm (usually about 0.5g/cm), specific gravity 1.26-1.31.
