Moreover, its film-forming ability contributes to the prevention of cracks, thus increasing the overall structural integrity.

  • The applicant claims that the feed additive HPMC is specified to be manufactured to meet the specifications set for its use as a food additive. The main specifications as food and feed additive are: methoxyl groups ≥ 19 and ≤ 30%, hydroxypropoxyl groups ≥ 3 and ≤ 12%, loss on drying < 10%, sulfated ash < 1.5% (for products with viscosities of 50 mPa.s or above) or < 3% (for products with viscosities below 50 mPa.s). Five batches of the additive were analysed for some of the above specifications, resulting in: methoxyl groups (four batches) 23.5–29.2%, hydroxypropoxyl groups (four batches) 5.2–8.4%, loss on drying (one batch) 1.2% and sulfated ash (one batch) 0.6%. Only statements, without figures, of compliance with the specifications for some impurities (heavy metals, arsenic, solvents, microbial purity) were provided. Information on other impurities ((pesticides, dioxins, dioxin-like and non-dioxin-like polychlorinated biphenyls, mycotoxins, botanical impurities) was not provided.

  • The solubility of HPMC in organic solvents is relatively low, but this property is utilized in certain applications where water resistance is desired, like in the production of water-resistant coatings or films.

  • The use of HPMC hard capsules is not just a bonus for vegetarians and vegans, it's also great news for the many consumers who avoid animal products — as long as there’s no perceived disadvantages compared with the animal-based original. However, as a conscientious consumer, it’s worth taking a look behind the all-natural image. Hydroxypropyl methylcellulose (HPMC), also known as hypromellose, is produced from cellulose, a natural polymer and fiber, which is considered to be safe for human consumption.

  • Furthermore, HPMC is also utilized in the production of personal care products like toothpaste, shampoos, and cosmetics, providing viscosity and stability to these formulations.
  • One of the key properties of HEC is its ability to thicken aqueous solutions. When dissolved in water, HEC molecules form a network of intermolecular interactions that trap and hold water molecules, resulting in a gel-like consistency. This thickening property is utilized in a wide range of products, including paints, adhesives, and personal care products.

  • 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.
