I wanted to show you how vanilla will change the color of a soap. Originally, the fragrance oil in the Fruit Loops batch turned the base yellow. A week later it remained unchanged but in the second week, it is changing every day. I don't expect it to get much darker.

The same is happening with my Chocolate Raspberry Bliss soap. Of course, I did know it would do this and considered it in my coloring of this batch and the Fruit Loops one as well.

Often times, people imagine a vanilla soap being very light-colored like vanilla ice cream, but in reality, it will be much darker like the vanilla bean itself. I've also had soap darken on me even though the fragrance didn't contain vanilla at all. That is always a bit puzzling and disappointing too if it interferes with the coloring of the soap.
I have thoughts of a new soap that will incorporate lots of vanilla, brown sugar, honey, chocolate, and possibly some almond. Mmmm.... I will need a few ingredients to make that one so that one will wait. You can bet my next one, whatever it is, will have heaps of glitter!
