• Propylene glycol dinitrate (PGDN, 1,2-propylene glycol dinitrate, or 1,2-propanediol dinitrate) is an organic chemical, an ester of nitric acid and propylene glycol. (wikipedia.org)
  • A study was made of possible neurotoxicity due to chronic or acute exposure to 1,2-propylene-glycol-dinitrate (6423434) (PGDN), a nitrated ester used in the torpedo propellant Otto-Fuel-II, in military personnel exposed during torpedo maintenance procedures. (cdc.gov)
  • Named after its inventor, Otto Reitlinger, Otto Fuel II consists of the nitrated ester explosive propellant propylene glycol dinitrate (PGDN), to which a desensitizer (dibutyl sebacate) and a stabilizer (2-nitrodiphenylamine) have been added. (wikipedia.org)
  • The Food and Drug Administration has classified propylene glycol as "generally recognized as safe," which means that it is acceptable for use in flavorings, drugs, and cosmetics, and as a direct food additive. (cdc.gov)
  • The Food and Drug Administration has classified propylene glycol as an additive that is "generally recognized as safe," which means that it is acceptable to use in flavorings, drugs, and cosmetics, and as a direct food additive. (ecolink.com)
  • As a food additive, propylene glycol is metabolized in the body and used as a normal carbohydrate source. (ecolink.com)
  • The U.S. version contains higher levels of propylene glycol, an ingredient that European countries limit more stringently than the U.S. Food and Drug Administration -- which allows 50 grams of the ingredient per kilogram -- does. (ibtimes.com)
  • 1998), has caused excess levels of propylene glycol in the body. (cdc.gov)
  • However, recent reports in the veterinary literature of scientifically sound studies have shown that propylene glycol reduces the red blood cell survival time, renders red blood cells more susceptible to oxidative damage, and has other adverse effects in cats consuming the substance at levels found in soft-moist food.

  • Further purification produces finished industrial grade or USP/JP/EP/BP grade propylene glycol that is typically 99.5% or greater. (wikipedia.org)
  • SAFE-T-THERM GRAS Biobased - NSF approved as HT1, it uses a renewable source USP grade propylene glycol and FDA approved corrosion inhibitors. (acculube.com)
  • SAFE-T-THERM Classic Biobased - Product uses renewable source industrial grade propylene glycol, is ideal for components in residential and commercial systems. (acculube.com)
  • SAFE-T-THERM HD Biobased - Ideal for high demand applications, it uses renewable source industrial grade propylene glycol, has an enhanced corrosion package. (acculube.com)
  • The waste TEG produced by this process has been found to contain enough benzene to be classified as hazardous waste (benzene concentration greater than 0.5 mg/L). Triethylene glycol is well established as a relatively mild disinfectant toward a variety of bacteria, influenza A viruses and spores of Penicillium notatum fungi. (wikipedia.org)
  • Much of the scientific work with triethylene glycol was done in the 1940s and 1950s, however that work has ably demonstrated the antimicrobial activity against airborne, solution suspension, and surface bound microbes. (wikipedia.org)
  • The ability of triethylene glycol to inactivate Streptococcus pneumoniae (original citation: pneumococcus Type I), Streptococcus pyogenes (original citation: Beta hemolytic streptococcus group A) and Influenza A virus in the air was first reported in 1943. (wikipedia.org)
  • Solutions of triethylene glycol are known to be antimicrobial toward suspensions of Penicillium notatum spores, Streptococcus pyogenes (original citation: Beta hemolytic streptococcus Group A ), Streptococcus pneumoniae (original citation: pneumococcus Type I), Streptococcus viridans, and Mycobacterium bovis (original citation: tubercle bacilli Ravenel bovine-type). (wikipedia.org)
  • The latter investigation suggests that triethylene glycol may prove to be a potent weapon against future influenza epidemics and pandemics. (wikipedia.org)
  • In the 1940s and early 1950s, further studies showed inactivation of diverse bacteria, influenza virus, and Penicillium chrysogenum (previously P. notatum) mold fungus using various glycols, principally propylene glycol and triethylene glycol. (wikipedia.org)
  • But a roundabout pathway does lead from acetyl-coA to pyruvate, via acetoacetate, acetone, hydroxyacetone (acetol) and then either propylene glycol or methylglyoxal. (wikipedia.org)
