Hello all, I made a kiwifruit batch recently - I'm no fan of fluro colours, but I was attracted by this picture of kiwifruit soap It seemed to me that the brown colour would be a natural result of the kiwifruit puree changing colour over time. What I was surprised by was that my soap (using hard white oils) came out very white, with a few seeds popping up here and there... Its been 8 weeks, and white it has stayed. So now I'm guessing that brown is the result of a fragrance oil (vanillin perhaps).. Attached is my ingredients list + puree amount. Any help in achieving a nice natural colour such as theirs is wonderfully appreciated ! Have I been wrong to assume that purees can add colour to soap?
