Hydroxypropylmethylcellulose

Beschreibung:

Hydroxypropylmethylcellulose (HPMC), mit der CAS-Nummer 9004-65-3, ist ein halbsynthetisches Polymer, das aus Cellulose gewonnen wird. Es zeichnet sich durch seine weiße bis cremefarbene Pulverform aus, die geruchlos und geschmacklos ist. HPMC ist in kaltem Wasser löslich und bildet ein viskoses Gel, während es in organischen Lösungsmitteln unlöslich ist. Diese Verbindung weist hervorragende Eigenschaften zur Filmformung, Verdickung und Emulgierung auf, was sie in verschiedenen Anwendungen, einschließlich Pharmazeutika, Lebensmitteln, Kosmetika und Baumaterialien, weit verbreitet macht. In der pharmazeutischen Industrie dient HPMC als Bindemittel und kontrolliertes Freisetzungsmittel in Tablettenformulierungen. In Lebensmittelanwendungen wirkt es als Verdickungsmittel und Stabilisator, verbessert die Textur und die Feuchtigkeitsspeicherung. Darüber hinaus ist HPMC ungiftig und biologisch abbaubar, was zu seiner Attraktivität in umweltfreundlichen Formulierungen beiträgt. Seine Vielseitigkeit und funktionalen Eigenschaften machen es zu einem wertvollen Inhaltsstoff in mehreren Sektoren, einschließlich der Körperpflege und industriellen Anwendungen.

(Hydroxypropyl)methyl cellulose - Viscocity 80-120 cP, 2 % in H2O (20 °C)

CAS: 9004-65-3

Hydroxypropyl methylcellulose (HPMC or hypromellose) is a semisynthetic, inert and viscoelastic polymer that is used as eye drops and as semi-synthetic substitute for tear-films. When applied, a hypromellose solution acts to swell and absorb water, by increasing the thickness of the tear-film, resulting in decreased eye irritation.  In addition to its use in ophthalmic liquids, hypromellose has been used as an excipient in oral tablet and capsule formulations, where, depending on the grade, it functions as controlled-release agent. It is also used as a binder and as a component of tablet coatings.  Hypromellose in aqueous solution, unlike methylcellulose, exhibits thermal gelation properties. HPMC is approved as a food additive, emulsifier, thickening and suspending agent, and as an alternative to animal gelatin (Codex Alimentarius code (E number) is E464).
