Store bought oils....

[NavyDood]

Just a quick question.



Cooking oil that you buy off the shelf at your local food store I. E. Veg oil, peanut oil, canola oil, sunflower oil, or olive oil.



Is it already glycerine free?

 

[JFaughn]

No its not , most vegi oils have about 20% , used oils can have more.

 

[DFerverda]

Glycerine is the stickey molecule in the oil, It takes the transvestifercvation process to remove it, ie lye+methanol+heat
