What does the term non-bleeding color mean?
General Non-bleeding colors or colorants are those that don’t migrate with other colors in your soap base. Bleeding or color migration occurs when the color you add in your soap does not stay in place or when the color “bleeds” or “leaks” into other parts of your soap bar. This usually happens with water soluble colorants and usually occurs with bright colorants (i.e. bright red, yellow, blue). Examples of non-bleeding colorants are oxides, micas and pigments.
