Was macht man mit Propylenglykol?
Verwendung. Propylenglykol ist in Lösungsmitteln und in Hygieneartikeln wie Hautcremes, Zahnpasta und Deos als Feuchthaltemittel und Weichmacher enthalten. Propylenglycol kommt als Kotensid in Mehrkomponentensystemen zur Anwendung und ist in der Lage, W/O-Emulsionen zu fördern.
Ist PG schädlich?
Reizungen oder andere minimale Effekte können auftreten, aber insgesamt ist Propylenglykol für Säugetiere und andere Primaten nicht sonderlich schädlich. Auch wenn der Rauch deutliche Schäden verursachte, gab es zwischen PG und Glycerin keine Unterschiede.
What happens when you mix water with propylene glycol?
The freezing point of water is depressed when mixed with propylene glycol. It is used as aircraft de-icing fluid. Water-propylene glycol mixtures dyed pink to indicate the mixture is relatively nontoxic are sold under the name of RV or marine antifreeze.
Are there any cases of toxicity from propylene glycol?
There is only one documented case of toxicity caused by food. A man drank very large amounts of cinnamon whiskey containing propylene glycol and was found unconscious. While his symptoms were also due to the alcohol, some could be attributed to the propylene glycol ( 10 ).
Are there any other names for propylene glycol?
Other names it is known by include ( 2 ): Propylene glycol is sometimes confused with ethylene glycol, as both have been used in antifreeze due to their low melting points. However, these are not the same substance.
How is the optical isomer of propylene glycol obtained?
Propylene glycol is a clear, colorless and hygroscopic liquid. Propylene glycol contains an asymmetrical carbon atom, so it exists in two enantiomers. The commercial product is a racemic mixture. Pure optical isomers can be obtained by hydration of optically pure propylene oxide.
