Baking soda, citric acid, sea salt, cornstarch and oils pressed into molds. Let them dry, then drop one in a full tub.
What You’ll Need
- 8 ounces baking soda 1 cup
- 4 ounces citric acid 1/2 cup
- 4 ounces sea salt 1/2 cup
- 4 ounces cornstarch 3/4 cup
- 2 TBSP carrier oil
- 2 tsp witch hazel or water in a spray bottle
- 1 tsp vanilla extract (optional)
- 60 drops essential oils of choice (optional)
- 2 TBSP dried flowers or herbs (optional)
- 10-20 drops natural food dye (optional)
- Digital scale bath bomb mold, medium mixing bowl, fine mist spray bottle
Equipment
- mixing bowl
- mason jars
Directions
- Stir the baking soda, citric acid, cornstarch, and sea salt together well in a large bowl.
- Stir the carrier oil, vanilla, essential oils, and dye (if using) together in a small bowl.
- Pour the wet mixture into the dry a little at a time, working it in with your hands until crumbly.
- Mix in the dried flowers or herbs, if using.
- Spritz with the witch hazel or water and mix by hand until the mixture holds together when squeezed (“should feel like wet sand”). If needed, add a little more witch hazel.
- Pack firmly into silicone molds, muffin tins, ice cube trays, or bath bomb molds.
- Flip the molds over onto a flat surface to release the bombs. Leave them to dry for 48 hours, or until hard.
Notes
Drop one in a warm bath. Store airtight away from moisture; shelf life about 6 months. This is a 0.5% essential oil dilution (1/2 percent, NOT 5 percent). Use caution with cinnamon, clove, ginger, and lemongrass oils. Dried herbs are a gentler choice for sensitive skin, and kid-safe blends are best for children. Safety: patch test; keep dry until use; wear a mask or work gently so citric acid dust is not inhaled and keep it out of eyes; dye and oils can stain or slick the tub; keep away from small children who might mouth them; not for internal use.
