I love to use the jojoba beads for coloring in my soaps. I have never had them melt or bleed. Sometimes I disperse them throughout the soap, sometimes I sprinkle them on top. But my most successful use of them has been to swirl with them. Makes for a fun and easy and stress-free swirl. Just make sure the soap has a good medium trace going or the swirls will sink to the bottom of the mold. They come in all sorts of colors. You can combine colors as well. Can be a bit scratchy when the soap is rubbed directly on the skin if the beads are on the surface of the soap. I think the drying out of the surface of the soap causes the beads to be a bit tough. They are rounded, of course, so no sharp edges. Still, can be a bit scratchy.
