CAS 9004-74-4

Etere monometilico di polietilenglicole

Descrizione:

Etere monometilico di polietilenglicole (PEG-ME), con il numero CAS 9004-74-4, è un tensioattivo non ionico e polimero ampiamente utilizzato in varie applicazioni, tra cui prodotti farmaceutici, cosmetici e processi industriali. È caratterizzato dalla sua natura idrofila grazie alla presenza di catene di polietilenglicole (PEG), che ne migliora la solubilità in acqua e la compatibilità con altre sostanze. Il PEG-ME presenta generalmente bassa tossicità ed è considerato sicuro per l'uso in molte formulazioni. La sua struttura molecolare include un gruppo etere metilico, che contribuisce alle sue proprietà uniche, come una maggiore stabilità e una viscosità ridotta rispetto ad altri derivati del PEG. La sostanza è spesso utilizzata come solvente, emulsionante o agente addensante, e può anche migliorare la biodisponibilità dei farmaci nelle applicazioni farmaceutiche. Inoltre, il PEG-ME è noto per la sua capacità di formare film e migliorare la texture dei prodotti, rendendolo prezioso nelle formulazioni cosmetiche. In generale, la sua versatilità e le caratteristiche favorevoli rendono il PEG-ME un composto ampiamente utilizzato in vari settori.

Poly-(ethylenglykol)-methylether-Mn 550

CAS: 9004-74-4

Poly(ethylenglycol) methyl ether Mn 550 is a polymer that has been synthesized by the reaction of MnCl2 and ethylene glycol. The thermal expansion coefficient for this polymer is about 1.8x10^-5/K, which can be used to determine the temperature changes in the environment. The ionization mass spectrometry analysis shows that it consists of Mn and oxygen atoms. This polymer has a diameter of around 2 nm, which can be determined by transmission electron microscopy (TEM). Poly(ethylenglycol) methyl ether Mn 550 has been shown to have catalase activity, which is an enzyme that breaks down hydrogen peroxide into water and oxygen gas. It also has growth kinetics that are dependent on the concentration of the polymer.
