I have been reading alot about diy ejuice and keep seeing stuff about diacetyl acetoin acetylpropionyl butyic acid and triglyceride. I have read most places stopped using diacetyl and in there place use acetoin and acetylpropionyl. Which I hear can have low percentages of diacetyl. But can also be harmfull. I looked on tfa and found a hand full that use acetoin and acetyl that I was going to order. But looked on fa and can't seem to find out what's in there juice. Is there a file or site that says what's in fa juice? Or are they free of these? Is there replacement concentrates that are free of these and give the same taste? I notice still people using concentrates that have acetoin and acetyl, is it some what ok to vape them at lower percentages? Or do people just figure it is still better then smoking cigarettes. I'm just trying to be on the safer side and understand if they are ok. Any input would be very appreciated.
