don't put those in an ecig. I'd assume they're all alcohol.
The vanilla is on 35% alcohol is that ok?
No. 35% is still pretty high. Most any bottle of whiskey you can buy at a liquor store is 40%. Vaping that stuff is gonna suck.
I do believe there are some McCormick flavors you can use, as they're only flavoring and pg, but most arent, so make sure to check that the labels dont say anything about alcohol or natural extracts/oils, those are both bad. Im not too sure about the other two brands, but again check the label.
Also another thing to keep in mind is that even the McCormick flavors you can use, you need a lot of it. They tend to be very weak in comparison to stuff like TFA or Lorann, and you end up having to double or even triple the percentage to get a comparable flavor.
Its best just to stick with the stuff that we know works.
Don't do it. There are no off the shelf McCormick flavorings that taste good in an E-Cig.
Cost/Benefit analysis - Best Case: You have flavorings to make juice right away. Worst Case: You end up wasting VG and Nicotine on unvapable juice. Also permanent lung damage.
I have 3 different vanilla extracts, those ingredients are all "extractives of vanilla bean in water" and "alcohol" but the pure peppermint and the pure lemon extracts both have no ingredients listed. Can I use any of these to mix with vegetable glycerin?
The 'pure' peppermint and lemon are likely the concentrated oil extracts. They're fine to eat but I'd avoid the essential oils as vaping flavors re: lipid pneumonia.
Also oils are hard to get to mix with your base. Also also there are other ways to get these flavors that aren't suspended in a fat.
