Poly(propylene glycol) Usage And Synthesis
  • Chemical PropertiesViscous colourless liquid (whose viscosity depends upon the average
  • UsesHydraulic fluids, rubber lubricants, antifoam agents, intermediates in urethane foams, adhesives, coatings, elastomers, plasticizers, paint formula- tions, laboratory reagent.
  • DefinitionChEBI: A macromolecule composed of repeating propyleneoxy units.
  • General DescriptionColorless liquid that is odorless or has a mild sweet odor. May float or sink in water.
  • Reactivity ProfilePoly(propylene glycol) is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
  • Health HazardThe compound has a very low toxicity; few, if any, symptoms will be observed. Contact of liquid with eyes causes slight transient pain and irritation similar to that caused by a mild soap.
  • Safety ProfilePoison by intraperitoneal and intravenous routes.When heated to decomposition it emits acrid smoke and irritating fumes.
