If you work with Ultramarine Blue, please note that the color can develop a "rotten egg" smell due to the presence of sulphur. This smell develops if the pH is above 6. To eliminate, keep the pH below 6 or add an acid resistant, and keep your pH above 6.5.

Mixing suggestion: Start with a bit of the colorant and slowly add your chosen medium to the colorant until you get the consistency you want. Once you have the desired consistency, incorporate the colored medium into the base you're working with. This process will minimize speckling and clumping.
Recommended medium for dispersion is glycerin, fragrance oil, or an ingredient oil in the soaps you're making.
