We offer two different types of colourant formulations, all manufactured on site. Glycerine based pigments which are used for opaque soap bases, and water soluble colours are used for clear soap bases, cold process soap and bath bombs. Pigment colours are non-bleeding, which means the colour will not run into the surrounding soap base. Ideal if you want to make different coloured layered soap bars. It is important not to use pigment colours with clear soap bases and vice versa, this is because pigments do not dissolve properly in clear soap base, and water based colours will bleed in opaque soap bases and not colour thoroughly. We recommened to add 1% colour they are highly concentrated, excess colour could alter the desired look of the lather on your soap bars.
