Making a soap with butterfly pea flower powder and purple sweet potato?

[slapsoap]

Has anybody used these and if so how did they turn out? Im just concerned these will turn out brown in soap making?

So sorry... both turn brown.
Use the Search icon (magnifying glass in upper right corner of this page) for each colorant separately to learn more.

Both are anthocyanin pigments (just like red cabbage, berries, wine, and hibiscus). So they don't survive the lye inferno of soapmaking undamaged.

Awesome thank yall both im new here and really appreciate the help!!

Do they turn brown even if added to hot process soap after the saponification is complete?

I can't tell about HP specifically, but when I incorporated butterfly pea powder into soap dough (that was essentially through saponification by that time), it had looked promising for a week or two, until it turned into a weird olive colour.

I've seen a greyish kind of brown from purple potato in soap. It was HP. I don't know when she added the potatoes though sorry.

Try it? Worst you'll get is nice lather hehehe

Hi I want to experiment with coloring with the butterfly pea flower powder. Does anyone know how to use it so it makes your soap blue?

Sorry to interrupt.
What about indigo powder?

I have not tried it myself, but I did some googling after reading a thread on the subject here at SMF and found these links below:

Found not to stay blue: Soap dough and late superfat/colour/FO addition

Using tea & not the actual powder also found to be unstable in CP soap: Butterfly Pea Flower Tea

For MP soap, see this link for more information on extracting the color from the flowers: Butterfly Pea Flower Soap Recipe

Indigo powder can work but it's also good for being a finicky pain in the butt too sometimes.

I have yet to get a natural blue. Indigo turns dark black and I do hot process

It sounds like you are using too much indigo powder, which will turn black when used in excess.

Have you tried infusing the indigo into your oils? Here is a video about that:
