Polietilenglicole

Descrizione:
Polietilenglicole (PEG), con il numero CAS 25322-68-3, è un polimero versatile noto per le sue proprietà idrofili e biocompatibilità. È composto da unità ripetitive di ossido di etilene, risultando in una struttura che può variare in peso molecolare, il che influisce sulle sue caratteristiche fisiche e chimiche. Il PEG è tipicamente un liquido incolore, inodore e viscoso o un solido ceroso, a seconda del suo peso molecolare. È solubile in acqua e in molti solventi organici, rendendolo utile in un'ampia gamma di applicazioni, tra cui prodotti farmaceutici, cosmetici e alimentari. Il PEG funge da lubrificante, umettante ed emulsionante, ed è spesso utilizzato nelle formulazioni farmaceutiche per migliorare la solubilità e la biodisponibilità. Inoltre, la sua natura non tossica e la capacità di formare idrogeli lo rendono prezioso in applicazioni biomediche, come sistemi di somministrazione di farmaci e ingegneria dei tessuti. Tuttavia, le proprietà specifiche del PEG possono variare significativamente con il suo peso molecolare e formulazione, il che deve essere considerato quando si sceglie per applicazioni particolari.
