CAS 9004-74-4

Éter monometílico de polietilenoglicol

Descrição:

Éter monometílico de polietilenoglicol (PEG-ME), com o número CAS 9004-74-4, é um surfactante não iônico e polímero amplamente utilizado em várias aplicações, incluindo produtos farmacêuticos, cosméticos e processos industriais. É caracterizado por sua natureza hidrofílica devido à presença de cadeias de polietileno glicol (PEG), que melhora sua solubilidade em água e compatibilidade com outras substâncias. O PEG-ME geralmente apresenta baixa toxicidade e é considerado seguro para uso em muitas formulações. Sua estrutura molecular inclui um grupo éter metílico, que contribui para suas propriedades únicas, como maior estabilidade e menor viscosidade em comparação com outros derivados de PEG. A substância é frequentemente utilizada como solvente, emulsificante ou agente espessante, e também pode melhorar a biodisponibilidade de medicamentos em aplicações farmacêuticas. Além disso, o PEG-ME é conhecido por sua capacidade de formar filmes e melhorar a textura dos produtos, tornando-o valioso em formulações cosméticas. No geral, sua versatilidade e características favoráveis fazem do PEG-ME um composto amplamente utilizado em várias indústrias.

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.
