Obsidian Lake is a nice and easy way to get a black bath bomb. No blooming required. If enough is used you will have a black bath bomb and the bath water will be a dark dark purple.
Lake pigments are oil dispersible colourants that tint by dispersion. This means unlike our water soluble dyes these colourants need an oil to distribute them in water. This makes them a great option for colouring bath bombs. Lakes will give your bath bombs a bright pop of colour and will colour the bath water if enough is used. No blooming needed! Just add these gorgeous colours to your baking soda and blend well until all lumps and colour streaks are gone and your baking soda. We use the back of a big spoon to smooth out the colours. Then add your liquids and mix! So easy! Don't add this to your oil first or you may get purple.
For bath bombs we use 2 + tsp per 1 cup of baking soda to get a good black. Test in a small batch to see what works best for you.
Always test before you sell.
Poly 80 is recommended to avoid a ring in the tub.
Lakes can be used in soap but may bleed. Colour not stable in high PH
Approved for all cosmetic use (eyes, lips, and face) including bath bombs.
