CAS 9004-62-0: Celulosa, éter 2-hidroxietílico
Descripción:
Celulosa, éter 2-hidroxietílico, comúnmente conocido como celulosa hidroxietílica (HEC), es un polímero no iónico, soluble en agua, derivado de la celulosa. Se caracteriza por la sustitución de grupos hidroxietilo en la cadena de celulosa, lo que mejora su solubilidad en agua y modifica sus propiedades reológicas. HEC se utiliza típicamente como agente espesante, estabilizador y formador de películas en diversas aplicaciones, incluyendo productos farmacéuticos, cosméticos y alimentarios. Es conocido por su capacidad para formar geles y mejorar la textura y viscosidad de las formulaciones. HEC también es biocompatible y biodegradable, lo que lo hace adecuado para aplicaciones respetuosas con el medio ambiente. Sus propiedades se pueden ajustar modificando el grado de sustitución y el peso molecular, lo que permite una amplia gama de usos funcionales. Además, HEC es estable bajo una variedad de condiciones de pH y puede soportar temperaturas moderadas, lo que lo hace versátil en sistemas acuosos y no acuosos. En general, la celulosa hidroxietílica es un ingrediente valioso en muchos productos industriales y de consumo debido a sus características multifuncionales.

CAS:Hydroxyethyl cellulose (HEC) is a polysaccharide that is used as a thickener and emulsifier in the pharmaceutical industry. It has been shown to be effective in treating human serum with detrusor muscle contractions. HEC is also used as a negative control for experiments involving the effect of drugs on HIV infection. When mixed with isoxsuprine hydrochloride, HEC can be used to measure the concentration of basic proteins in human serum. The fluorescence probe can bind to specific regions of the protein, which will cause an increase in fluorescence when exposed to a wavelength of light. The optimum concentration of HEC for binding fluorescence probes was found using Langmuir adsorption isotherm measurements and fluorescence detector experiments. HEC has been shown to be an effective antimicrobial agent against bacteria and fungi, such as Staphylococcus aureus and Candida albicans.

CAS:Hydroxyethyl cellulose (EHEC) is a non-ionic, water-soluble cellulose derivative produced by introduction of ethylene oxide groups to the hydroxyl groups of the cellulose backbone. Hydroxyethyl cellulose is useful as a water thickener, rheological control additive, protective colloid, binder, stabilizer, suspending agent and film former. It is used in many industrial applications including latex paints, emulsion polymerization, petroleum, paper, pharmaceuticals, cosmetics and many other applications.Pureza:Min. 95%Forma y color:PowderRef: IN-DA00ILIZ
