I have done two orange experiments recently, and both have come out nicely.
Orange Experiment 1 has no added colour in it, but it does have grated fresh orange peels, freshly squeezed orange juice and both Sweet and Bitter Orange essential oils. I think the essential oils are what colour this soap a nice light orange... We will see if it lasts.
The second one is much oranger. Basically the same soap, superfatted slightly higher but with a little Annatto powder added to the lye solution and also at trace. You can see slight specs of the powder in the soap. The bigger spots that you can see in the first soap were the orange peels. This time I blended them up more.
Now that I am really liking the look of my Seville Orange soap... I need to find an orange essential oil blend that STICKS and ENTICES. This one is not bad, but slightly sweet from the Geranium... I can't wait to try out the 10-fold Orange Essential Oil I recently ordered!
Next experiment: Turmeric
