This homemade bubble bath powder makes firm, high-quality, and long-lasting bubbles that will delight bathers of all ages. So scoop and build with them or relax under the suds, however your bathing pleasure, this is a quick DIY project that only takes a few ingredients.
Use a metal whisk or spoon to sift the baking soda and SLSA powder through a fine mesh strainer placed over a large mixing bowl. Wear a mask and work in a well ventilated area to prevent breathing in the powders as you mix ingredients together.
Stir in citric acid. If you are adding essential oils and color dye, now is the time. Begin with 40 drops of essential oil (your choice of scent) and 10 drops of liquid dye. Mix well, test, and adjust as you see fit.
Measure the liquid bubble bath with a dropper or teaspoon and squirt it over the dry powder. Mix again well.
Line a flat surface like a rimmed baking sheet or 9x13-inch glass baking dish with parchment paper and spread the powder in a thin even layer. Wait 12-24 hours until dries completely.
Once dry, lift the paper liner up, dump the contents into a strainer resting over a bowl for the last sifting. Use the back of a spoon to break apart all lumps.
Transfer the powder to a storage jar and keep in the bathroom for use. Add 3-4 tbsp under running water as you fill the bath.
Notes
Double check that the powder is bone dry (no moisture left!) before bottling for storage. Even the smallest amount of moisture could negatively react with the citric acid and cause built up pressure that eventually breaks the bottle. We don’t want that!Storing in mason jars with open cut daisy lids is the ideal presentation for easy pouring and makes a great gift.I share more important notes and tips in the post above (like where to find ingredients, how to make a multicolor powder, and more).
