Question about re-creating a salicylic acid toner, please

Hi, all.
I would like to create a scaled-down version of this toner, ingredient list shown below.  I have a question about creating just the "BHA"/salicylic acid portion of it.

  1. Is it most likely that they are solubolizing the salicylic acid in the butylene glycol?  Or the ethanol?  I assume this is a fairly easy process and that no extra solubolizing agents are needed (assuming the below list is 100% complete/accurate)?
  2. Is it correct that they are not using any additives to adjust the pH higher?

Thank you.

    The Salicylic Acid is most likely dissolved in a combination of Butylene Glycol and Alcohol.

    Thank you, @MarkBroussard.  So combine them together (maybe 5-7pct concentration each?), heat them up, and then add 1-2% salicylic acid?

    Yes, that would appear to be about right.  Firgure the Glycolic Acid is loaded at 8-10%, so you would be in the right ballpark
