  Does the Rec. Percentage apply to the entire solution or to the active ingedient?

  Posted by Wickers on June 24, 2020 at 9:46 pm

  Hi,

  I was wondering: you know how most suppliers usually list the recommended percentage for an active solution? Like 0.1%-2%?

  What if the ingredient supplied is a peptide, for example, and the INCI is: Water, Glycerin, pentapeptide-3

  If the active (or extract) is listed at 20% of the solution, do I have to scale up the recommended percentage to 0.5%-10%?

  I’m not sure if they mean 0.1%-2% as in the active ingredient is supposed to be that amount, or if the whole solution is to be that percentage of the final formulation.

  This was puzzling me for quite a while, but I thought it was a stupid question.

  Thanks in advance!

  Vendor recommendation is for how to use their specific product. So recommended % usage applies to the whole solution, no other math required.
