Ginger Peach Jam Test Batch

While testing another fragrance in cold process, I didn't expect to encounter such a great chemistry experiment! I used titanium dioxide to whiten the yellow hue of the natural soap (which is caused mostly by the palm oil) and colored the other half of the swirl with cellini blue mica. I was expecting this color:... not pink and then purple! Immediately, the raw soap turned a bright pink and by the end of the day, the color deepened into a beautiful purple. When I put my used Pyrex in the sink for a rinse after I finished pouring, the pink soap leftover in the dish turned bright blue as soon as the water hit it. This is a great reminder to always do a small test batch when using a new color or fragrance for the first time before making large quantities, particularly if you intend to sell your soap. I'm curious to see if this batch will go back to blue by the end of the month-long waiting period. Either way, it smells great and will make a wonderful addition to our bulk loaf soaps for sale in the store!

  1. Isn't the Cellini Blue the best? I love how it does that - it's a perfect Purple color...

  4. I love both... the blue and the purple. It is amazing how chemistry works... who would have thought that gorgeous blue would turn that pretty purple.

  5. Fun, right? I really like the purple, which has stayed true for a couple weeks now. Makes me want to use it in a lavender bar. Thanks for the comments!
