You will need:
8 oz Sodium Bicarbonate (Baking Soda)
8 oz Lathanol LAL (SLSa)
2.5 oz Cream of Tartar (Tartaric Acid)
1 oz Vegetable Glycerin
1 oz Cocamide DEA
1oz Cocamidopropyl Betaine
5ml (1 tsp) Fragrance
2 Stainless Steel or Glass Mixing Bowls
Silicone Molds, Soap Molds or a Silicone Loaf Pan
Phase 1: Wearing a facial mask to protect against inhaling airborne particles, gently combine all dry ingredients in a stainless steel or glass bowl. You may need to sift the dry ingredients to ensure there are no lumps.
Phase 2: Add fragrance oil to the dry mix and carefully mix together. Try to avoid over-agitating the dry ingredients as they are very light and will become airborne easily. SLSa can irritate air passages and should by handled in a well-ventilated area while wearing a mask for added protection.
Phase 3: Add liquid ingredients slowly while kneading ingredients together. The mixture will begin to take on the consistency of dough. When the mass begins to hold together in your hand, you are ready to add color.
Phase 4: Add liquid or powdered colorant to your preference. Your mixture will take on a pastel hue. Mix thoroughly until color is fully incorporated and no white spots are left. Set aside.
Phase 5: To create a multicolored effect you can layer two different colors of "dough" into a loaf pan or you can combine both colors into a single mass for a streaked or marbled effect. However you choose to combine your "dough" be sure to firmly press the mixture into your choice of mold to help the finished product hold together as it dries. (It may be helpful to grease or powder your mold for easier release.)
Phase 6: After an hour, you may begin to remove your bubble bars from their molds for curing or to cut your bubble loaf (if you used a loaf pan). Once your bubble bars are ready, place on a lined cookie sheet and allow to further cure overnight.
Phase 7: Once your bubble bars have hardened, package in an airtight container until use.
To Use: Drop a bubble bit under warm running water and watch the foam pile-up!
