1/2 cup light oil (sunflower, canola, or almond)
3-6 essential oil
1 cup baking soda
1 cup citric acid
3/4 cup cornstarch
4 drops of food coloring (optional)
1 muffin or ice-cube tray
Mix the oils and set aside. Combine all dry ingredients then stir in oil mixture until it forms a crumbly dough. If you’re using food coloring knead it in now. Pack the mixture into the molds and let set overnight. Unmold the next day and let air-dry. Use anytime by dropping one lavender bath bomb into a bathtub of warm water.
Keeps indefinitely if stored in a cool dry place.
