For some pictures of soaps that some or our members have made using beta Carotene as a colorant, I have included a few links. Since they were not my soaps, I am not linking to their photos, only to the original posts:
posted in 2015 a photo of a deep yellow soap she made using beta carotene.
entered a lovely mosaic soap
in last June's SMF Mosaic Soap Challenge. The color came out a very nice orange in this soap.
Others have mentioned it, but I wasn't able to find more photos of the corresponding soaps. Susie
once said she uses it often. Others who mentioned using Popcorn Oil (Coconut Oil colored with beta carotene for a buttery looking popped corn) said the soap turns out orange.
I have used it myself a few times and my photo of one of my Challenge entries is not anywhere near as nice as the two above, but here
it is. I also made some pumice soap for my brother using beta carotene last June and it came out orangish-yellow, using 2 capsules in about 1/3rd of a total batch size of 1547.5 grams. That soap is pictured below, although not pretty soap, the color is clearly orangish-yellow. (It was meant to be a Clyde Slide, but the pumice seemed to thicken the batter too much for any kind of smooth swirl technique.)
