Cellulosa, etere 2-idrossipropilico

Descrizione:

Cellulosa, etere 2-idrossipropilico, comunemente noto come cellulosa idrossipropilica (HPC), è un derivato non ionico e solubile in acqua della cellulosa. Viene prodotto mediante l'eterificazione della cellulosa con ossido di propilene, risultando nell'introduzione di gruppi idrossipropilici nella struttura della cellulosa. Questa modifica migliora la sua solubilità in acqua e solventi organici, rendendolo utile in varie applicazioni. HPC è caratterizzato dalla sua capacità di formare soluzioni chiare e viscose, il che lo rende prezioso come agente addensante, agente filmogeno e stabilizzante in prodotti farmaceutici, cosmetici e alimentari. È anche noto per la sua biocompatibilità e bassa tossicità, il che amplia ulteriormente la sua applicabilità nei campi biomedici. Inoltre, la cellulosa idrossipropilica presenta proprietà termoplastiche, consentendo di essere lavorata in varie forme. La sua stabilità chimica e resistenza alla degradazione in condizioni normali contribuiscono alla sua longevità nelle formulazioni. In generale, HPC è un polimero versatile con una significativa utilità in più settori grazie alle sue proprietà uniche.

Hydroxypropyl cellulose - Average MW 100,000

CAS: 9004-64-2

In water, hydroxypropyl cellulose forms liquid crystals with many mesophases depending on concentration. These mesophases include isotropic, anisotropic, nematic and cholesteric, the latter resulting in many colors such as violet, green and red. Pharmaceutical applications include treatments for medical conditions such as dry eye syndrome (keratoconjunctivitis sicca), recurrent corneal erosions, decreased corneal sensitivity, exposure and neuroparalytic keratitis. It is also used as a binder in tablets. Hydroxypropylcellulose is also used as a thickener, a binder and emulsion stabiliser in foods with E number E463.  HPC is used as a support matrix for DNA separations by capillary and microchip electrophoresis.
