Poly(ethylene glycol) methyl ether - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | polyethylene glycol monomethyl ether is a derivative of polyethylene glycol, soluble in water, ethanol and most highly polar organic solvents, compared with glycerol, it is not easy to volatilize, has stable chemical properties, is not easy to be hydrolyzed and destroyed, and has strong hydrophilicity. Vapor pressure, thermal stability, in the textile printing and dyeing industry and the daily chemical industry as a thickener, lubricant. In the building materials industry, it is used as the raw material of cement water reducing agent and reinforcing agent. The polycarboxylic acid superplasticizer synthesized by using the raw material has strong cement particle dispersion retention ability, so that the product has low dosage, high water reduction rate, good enhancement effect, durability, no corrosion of steel and environmental friendly and other advantages. Can be applied in the field of mixing and long-distance transportation of high performance, high strength (C60 or more) of the goods in the concrete. |
| Application | polyethylene glycol is a polymer of ethylene oxide hydrolysate, which is non-toxic and non-irritating, and is widely used in various pharmaceutical preparations. Low molecular weight polyethylene glycol is relatively toxic, and the toxicity of diols is relatively low. Topical application of polyethylene glycol, particularly Mucosal administration, can cause irritant pain. In the external lotion, this product can increase the flexibility of the skin, and has a similar moisturizing effect with glycerin. High-dose oral polyethylene glycol can appear Diarrhea. In the injection, the maximum concentration of polyethylene glycol 300 is about 30%(V/V), and the concentration of more than 40%(V/V) can appear hemolysis. |
