Black is an FDA approved batch certified dye. This dye offers an amazing black color to your bath water.
Although the water turns black it does not color your bath bomb black. It will be a dark green.
To get your bath bomb black you will need to add Activated Charcoal or Black Oxide. You will need to add poly 80 for this.
