Question regarding vanilla discolouration

Soapprentice · May 3, 2017

Hey guys, I have a question regarding vanilla. Suppose if we separate the batter into two and added 2 separate FOs one being vanilla and used them in the same soap, does vanillin discolour the part with no vanilla too?

Nope, only the part you add it to. You can do some swirls with uncolored batter or other colors. Gold is a nice shade to put against that brown. If you want to be certain of a good brown, though, use a colorant for it. Cocoa makes a nice brown.

As Susie said, cocoa makes a nice brown.

In my April stripes entry, I used vanilla and with cocoa to intensify the brown. Some of the layers went through multiple heating and cooling. All of the browns stayed in their own layers.

In my opinion, it depends. I've had discoloring fragrances bleed. Not sure exactly which circumstances led to that. I'm guessing water content, temp, and the fragrance itself but if you figure it out, please tell. It's worth trying tho!

I had wanted to implement something like that for last months challenge but I've been too busy as of late.

Ah! Thank-you. I forget sometimes that the FO will add another influence that the diluted extract of vanilla doesn't have when it comes to bleeding colours.
