Liquid non-migrating soap dye is black and ideal for handmade soaps. By mixing different bases and possibly other dyes, you can achieve various interesting shades and levels of transparency in the finished soap. The number of drops of dye affects the intensity of the colour. Add the dye to the melted base and mix everything until a uniform mixture forms. If using a base for making cream soap, it is not necessary to melt the base. We recommend testing the resulting colour on a small sample of soap base before you start creating.
