In a large mixing bowl, add the baking soda, powdered buttermilk and cornstarch. Whisk dry ingredients together.
Add the coconut oil. This binds all the ingredients together, so you bath bombs don’t crumble when you touch them! Next, add the polysorbate 80. This helps the coconut oil disperse more evenly in your bath water, makes the bath bombs bubbly and prevents the colorant from sticking to the side of the tub.
Add the colorant to the bath bomb mixture.
Mix everything together thoroughly. You may need to use your hands to break down any lumps and make sure everything is mixed in. The mixture is perfect when it holds together when you press it into your hands and feels like wet sand.
Mix in the Vanilla Chai Tea.
Add the mixture to the bath bomb press until they are slightly overflowing. Fill the other side of the mold with the mixture.
Press molds together.
Grind molds together to remove the excess mixture.
Gently tap each side of the mold to release the bombs. Allow to dry a minimum of 24 hours. If your climate is wet or cold, allow an additional 24 hours. My rule of thumb is that when it is hard to the touch, they are ready for the tub! Store in an airtight container until ready for use.
