    But many ingredients have some color that affects the color of the final product. Most of the extracts have a fairly distinct color, they are generally quite neutral - yellow, orange, green, but how to judge if these colors have an impact on marketability? I once made a face toner with a few extracts and believe me or not, I unintentionally got a rather distinct yellow-orange color. I couldn’t decide whether this color was good or not - on the one hand it was a nice vivid color, on the other hand it looked a bit like urine  ;)

    We better not even mention what a few drops of Buah Merah oil does to one of my creams.  (Few drops in 150 gram trial)  :D  Good thing is is only in there for the ORAC value. :)  **WARNING**  if you apply Buah Merah neat…you will look like TRUMP!  :D   *** DISCLAIMER*** Samples get used so fast…I have NO IDEA how long the color lasts.  :p

    I don’t recall seeing it much above the 7% range.

    but wasn’t sure if it’s the one high in rosmarinic or carnosic.
