Black Oxide liquid colourant is a pigment that has been suspended in vegetable glycerine. This product produces a true black in clear Melt and Pour soap base and is a cosmetic grade colourant that is stable and non-bleeding in soap.
Add colour to your base drop-by-drop. Adding more drops will produce a darker colour. If your soap bubbles are not white you have used too much colour. Adding this colour to white melt and pour soap base will produce a pastel grey coloured bar of soap.

Solubility: dispersible in water so suitable for water based products such as soap. Not suitable for oil based products such as lotions and creams.
Product pH: Stable in products with a high pH so it will not change / morph in cp soap.
Colour Fading: This colour is not sensitive to light so will not fade in your soap.
Colour Migration: This colourant is non-bleeding so is suitable for making soap with layered colours or embeds as it will not migrate or “bleed” between the layers.
