What about frozen grape juice cubes with lye instead of water..

[whitetulips]

I have some homemade grape juice (without preservatives) that probably should be thrown out. I thought that perhaps I could use it instead of water with lye (as frozen cubes because of the sugar content) and perhaps get some purple coloring from it. If it turns brown, that wouldn't be good, though. Anyone done this before?

I haven't tried it but I think the grape juice would turn brown (just my opinion). I've used different wines and the beautiful colors of red/purple have always turned brownish. Even the batches in which I used white wine also discolored. The batches all have discolored to a tan or slightly darker.

If I used it in a soap that I wanted a brownish color, do you think there would be any grape scent still left? Did your wine scent stay in your soap when it was finished?

Most food/liquid scents don't survive the lye. Scents have to be very concentrated to remain in soap like fragrance oils and essential oils. I doubt the grape scent would make it through saponification. However, I've never used it so I could be wrong. I can't say if any wine scent did survive saponification. I've always scented the batches.

You're not going to be able to retain the scent of the colouring of the juice unfortunately.

Would there be any benefits from the grape juice though? even though the smell wouldn't remain would any of the goodness?

The sugar from the juice would add to the bubbles, but that's about it.
