Ultramarine Blue liquid colourant is a pigment that has been suspended in vegetable glycerine. This product is a deep, true blue shade of colour 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 M&P soap base will produce a pastel coloured bar of soap.
INCI: Glycerine, Ultramarine CI 77007
Usage rate: 15ml will colour approximately 5kg of soap for a medium shade. Recommended usage rate is roughly 6 drops per 100g.
Melt and Pour Soap: Yes
CP soap: Yes
Lip Products: No
Not suitable for oil based products such as lotions and creams.
Not Suitable for Bath Bombs, Bubble Bars and Bath Salts as it can cause staining.
Colour: Produces a true blue at full strength in clear melt & pour soap base and a pastel blue colour in opaque (white) melt & pour soap base. In CP soap you really need to colour at medium strength to achieve a nice blue shade as it will otherwise end up looking like faded jeans.
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.
