  • 2 tablespoons coconut oil
  • 2 teaspoons lavender essential oil

What happens if You Don’t Use Citric Acid?

The most obvious thing that will happen if you do not use Citric Acid in your bath bomb will be no chemicle reaction with the baking soda. These are the two ingredients that when coming into contact with water produce the fizzing your expect from bath bombs.

I mean, who’s to say a bath bomb needs to fizz right? But, it is srt of the point and what we have come to know as a normal bath bomb behaviour, so to be non fizzy sort of make it pointless and you may as well be using bath salts instead.

That doesn’t mean you can’t make bath bombs without citric acid. Oh no, there are alternative ingredients if you either do not want to use Citric Acid, or if you have everything else to hand but no citric acid.
