Dippels animal oil

Dippels animal oil or essential animal oil ( Oleum animale aethereum , Oleum animale Dippelli ) is an initially colorless essential oil named after its maker Johann Konrad Dippel (1673–1734) , which then turns yellowish or brown.

At the time, it was produced by repeated distillation from the stinking animal oil ( Oleum animale foetidum crudum , raw animal oil), a strongly smelling animal oil with alkaline , nitrogenous compounds.

Dippels Oil achieved fame through Dippels claim in his dissertation to have found an Elixir vitae , a universal medicine . It was used for typhus , epilepsy and rubs. With three parts turpentine oil it forms the oleum contra Taeniam Chaberti , an old tapeworm remedy . However, Diderot raised doubts about its effectiveness in epilepsy in the Encyclopé .

According to Georg Ernst Stahl, Dippel's animal oil was of crucial importance in the discovery of the pigment Berlin blue by Johann Jacob Diesbach .

In the first photographs by Joseph Nicéphore Niépce in 1827, the photosensitive layer consisted of Judea asphalt , which was dissolved in Dippel's oil and then applied to a tin plate.
