If you are new to soap making, you undoubtedly have many soaping questions. One question or concern that jumps to my mind (because I receive calls or emails weekly) is about "color bleeding". First, let's clarify that color bleeding doesn't mean the soap color stains your body while bathing. Color bleeding, AKA "color migration", occurs when the color is not appropriate for the material/application being used (Melt and Pour soaps, in this case) .
The colorant type used in melt and pour soap base determines whether a color bleeds. You need to select color types that are labeled as non-bleeding. I've pictured two examples of noticable color bleeding. See how the colored embeds have bled (migrated) into the surrounding white or clear soap base? Over time, the color penetrates and bleeds (migrates) into all of the edges of the embedded material. It's not a pretty site, but is easily fixed by using the right pigments. I'm guessing food dye was used to color the embeds pictured. These are NOT a good choice for soap but often used by beginner soapers.
To avoid the problems presented in these photos, purchase non-bleeding pigments. GoPlanetEarth offers a large selection of non-bleeding pigments/dyes that are colorfast and give outstanding color intensity. When you see the term "non-bleeding" next to a color on our web site, you can be assured the color is non-migrating and you won't experince the problems shown in these pics.
